Comparing green space for urban cooling, study
Cities can become dangerously hot during extreme heat events, making it increasingly important for urban planners to find ways to reduce temperatures and protect people from heat exposure. Woodlands, grasslands, lakes and rivers can create significantly cooler microclimates, offering one potential way to reduce urban heat, a new study finds. The study focused on Guildford, […]
Rapid wetland loss and ‘real estate boom’ increasing flood risk in Lagos
In July, following relentless bursts of rainfall, flash floods covered pockets of Lagos, disrupting commerce and traffic in Nigeria’s commercial capital. Experts have found that the city now faces increased flood risk due to human-induced climate change. Other recent studies have identified another common factor exacerbating flooding risk in Lagos: rapid urbanization. In a study […]
Singapore spending billions to adapt to climate change, but deforestation continues
- Singapore is preparing its first national climate adaptation plan as temperatures and extreme rainfall increase, but the city-state is also clearing forests for housing.
- The planned development of Maju Forest and Gillman Barracks has triggered rare public protests, with residents arguing that Singapore’s environmental impact assessments fail to account for forests’ role in climate adaptation.
- Scientists say forest loss could increase heat and flood risks, while Singapore is spending billions on engineered climate defenses such as drainage, seawalls and heat-resistant paint.
- The conflict puts Singapore’s “city in nature” vision under scrutiny, as conservationists question whether tree planting and managed greenery can compensate for the loss of forests.

Recording a rainforest before Indonesia’s new capital changes it
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. In the forests around Pemaluan in East Kalimantan, Indonesian Borneo, researchers led by Wendy Erb at the Cornell K. Lisa Yang Center for Conservation Bioacoustics in the U.S. have placed audio recorders on mountains, beside caves, and among […]
Singapore made a crow-friendly city. Now it wants to shoot them
The resumption of a crow-shooting campaign in Singapore has revived intense debate over lethal wildlife management in the highly urbanized city-state. Government officials revived the culling program in response to public complaints about crow attacks on pedestrians and cyclists, reports contributor Robin Hicks for Mongabay. In a public statement in March announcing the resumption of […]
How ‘gentle power’ can preserve traditional biodiversity in Tokyo
- In Japan, satoyama are rural landscapes with natural attributes that have also been shaped by centuries of human activity.
- Tokyo’s satoyama provide habitat for many kinds of animals, including ecologically sensitive amphibians.
- A recent study examined a satoyama conservation initiative in Tokyo, finding that it succeeded by prioritizing mutual trust and collaboration — an approach the study defines as “gentle power”.
- Yet, some say this approach, which is based on volunteer participation, can stagnate as the volunteers are typically older, leading to the challenge of “how to pass this on to the younger generation.”

Urban heat islands have solutions; many tropical cities can’t afford them
- In tropical cities, urban heat islands (UHIs) exacerbate an already challenging hot-humid heat burden for residents. UHIs are formed by urban artificial surfaces like concrete and asphalt that retain heat by day and slowly release it at night, never giving cities a chance to cool.
- Natural and infrastructure solutions can be implemented to combat the UHI effect and cool cities. These include creating shade by planting trees or extending roofs; inducing wind to blow down urban streets; constructing green roofs and walls; painting roofs light colors; and changing social practices to avoid midday heat.
- But sufficient funding is needed to implement many of these changes. Wealthy cities, like Singapore, have an advantage over cities with less funding. Many tropical mega-cities, including Lagos, Mumbai, Manila, Jakarta and São Paulo, are working to reduce UHI effects, but struggle to afford full implementation.
- The 2026-2027 El Niño is now growing in strength and expected to bring record temperatures to the tropics. These extreme temperatures, combined with UHI effects and urban poverty, could prove deadly for vulnerable residents, which include the poor, young, old, those with disabilities, and those working outdoors.

As Singapore culls ‘nuisance’ birds, rapid urbanization continues to fuel an avian boom
- A campaign to shoot crows has resumed in Singapore in response to a surge in public complaints about attacks, with authorities saying “pest” birds pose a public health risk and outcompete native species.
- Ecologists argue Singapore’s crow problem is human-made, with poor waste management and illegal feeding fueling a population boom.
- They criticize culling as ineffective over the long term and say it risks normalizing lethal wildlife control while undermining Singapore’s “City in Nature” vision.
- Nature groups say ongoing and planned forest clearance for public housing could lead to further increases in urban bird populations, as more favorable habitats are created, leading to “endless culling” to control bird populations.

In Manila’s shadow, a forest refuge still shelters rare plants
A mountainous reserve near Manila, the Philippine capital, is a critical ecological refuge, harboring high levels of plant diversity despite its proximity to the highly urbanized city, according to a recent study. The findings come from surveys done 10 years earlier, however, and mounting pressures on the area’s forests since then may have had an […]
Looming loss of Singapore’s Maju Forest to development raises many questions (commentary)
- A 23-hectare (57-acre) forest in the Singaporean neighborhood of Clementi that provides stress relief and community enjoyment for residents, plus habitat for urban biodiversity, has been proposed for development, sparking a public debate.
- Although Singapore has earned recognition for integrating nature into this, one of the world’s most densely populated urban environments, the proposal would convert most of it into public housing.
- A new op-ed argues that urban forests are essential public health infrastructure and that this debate reflects a challenge that cities increasingly face: How should we value mature ecosystems in an era of climate change, urbanization and rising health challenges?

‘My Wild City’ reminds us why cities need nature
In her upcoming book, My Wild City: Finding Nature, Meaning, and Hope in India’s Capital, conservation biologist Neha Sinha takes readers to the hidden and not-so-hidden ecosystems of India’s largest city. And while the book expertly details the biodiversity, I believe its greatest strength lies in connecting with the reader emotionally through powerful stories from […]
As Indonesia’s new capital rises, the sounds of Borneo’s rainforest are changing
As Indonesia constructs its new capital, Nusantara, in the mountains of East Kalimantan in Borneo, the roar of chainsaws interrupts the rainforest sounds that have long been part of the cultural heritage of the Indigenous Balik community. New documentary, Sound Guardians, a collaboration between Mongabay, Scientific American and Project Multatuli, follows efforts by scientists and […]
Extreme heat is eroding health, productivity and incomes of Dhaka’s informal workers
- Nearly 75% of migrants in Dhaka, the capital of Bangladesh, reported being negatively affected by rising temperatures, while 100% reported being affected by extreme weather events.
- Bangladesh’s maximum temperature has increased by 1.1°C since 1980, while the country’s “feels-like” temperature has risen by 4.5°C.
- In 2024 alone, heat-related illnesses and productivity losses contributed to the loss of 250 million workdays, costing Bangladesh an estimated $1.78 billion, equivalent to 0.4% of GDP.
- Bangladesh’s informal economy employs approximately 85% of the national workforce, nearly 60 million people making heat stress not only a public health issue but also a major economic concern.

Could a blighted urban inlet become a global beacon of waterway renewal?
- A group of advocates is seeking to transform False Creek, a tidal inlet in Vancouver, Canada, from a polluted city inlet into a place where nature thrives and people can safely swim in the water.
- Facing jurisdictional challenges over who gets to decide the future of this once vital marine ecosystem, advocates have explored various governance models for the inlet, such as getting it designated as an urban marine park or granted environmental personhood.
- Not everyone agrees, and now, they are pushing for the surrounding community to voice their desires and negotiate for False Creek’s future.

Dusky langurs start using new canopy bridge in Malaysia’s Penang Island
Endangered dusky langurs have successfully begun using a new artificial canopy bridge in a major tourism hub on Malaysia’s Penang Island. Camera traps set up by the Langur Project Penang (LPP) confirmed that the first dusky langur (Trachypithecus obscurus) crossed the bridge made out of old fire hoses on June 1, about two months after […]
Bangladesh unveils sweeping EV incentives to cut emissions and pollution
- In the national budget announced on June 11, the Bangladeshi government waived tariffs on the import of electric vehicles (EVs) such as buses and trucks between July 1, 2026, and June 2030, while increasing tariffs on fossil fuel-run vehicles.
- A tariff waiver was also announced for setting up charging stations for EVs.
- The government aims to replace 25% of buses and 30% of trucks with electric alternatives, in line with the Nationally Determined Contribution (NDC).
- Besides adaptation, the South Asian country is now embarking on mitigation to reduce carbon emissions and air pollution that kill hundreds of thousands of people every year.

Old fire hoses become lifelines for Malaysia’s endangered langurs
On Malaysia’s Penang Island, conservationist Yap Jo Leen is turning old fire hoses into lifesaving bridges that help endangered monkeys cross busy roads in residential areas. The idea took root after she witnessed a female dusky langur and her infant get struck by a vehicle in 2016, Yap told Mongabay’s Phil Jacobson and AFP’s Isabelle […]
Urban wildlife is changing from the inside out (commentary)
- Cities are now home to wildlife like foxes, parrots, monkeys, raccoons, boars, and countless bird species, which are not temporary visitors, but permanent urban residents.
- If we want to support their long-term survival, we need to understand how urban environments shape them at every level, from behavior to bacteria, and this includes their gut microbiome, which shapes behavior and other factors.
- “The microbiome is not a niche scientific curiosity, it is a biological system that influences how animals eat, think, move, and cope with stress. And in a rapidly urbanizing world, it may be one of the most important and overlooked tools we have for understanding how wildlife adapts to human-dominated landscapes,” a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Three new ‘planking’ praying mantis species found in Australia and Papua New Guinea
Researchers have identified three new-to-science species of snake mantises, two from Australia and one from Papua New Guinea, and figured out their distribution and behavior with the help of citizen scientists. Matthew Connors, a Ph.D. candidate at James Cook University in Australia, led the effort to revisit the taxonomy of Kongobatha, a little-studied group of […]
As African cities heat up, a new book argues trees are part of the solution
- Africa’s population is now estimated at nearly 1.5 billion people; the continent is urbanizing faster than any other region in the world and projections suggest that nearly 80% of future population growth will take place in urban areas.
- As the climate continues to warm, scientific evidence shows with high confidence that hot days and nights will become more frequent, while many coastal cities are expected to face increasing flood risks related to rainfall events and sea level rise.
- Across the continent, national authorities, city councils and local governments are increasingly turning to trees and green spaces as part of the solution. But the effectiveness and long-term sustainability of many of these initiatives continue to raise questions.
- A new book documenting 34 case studies from Southern, Eastern, Western and Northern Africa places trees and urban green spaces at the center of efforts to address the continent’s intertwined climate, biodiversity and inequality challenges.

Building bridges for human-wildlife coexistence: Interview with Yap Jo Leen
- Conservationist Yap Jo Leen launched the Langur Project Penang after witnessing dusky langurs, an endangered monkey she was studying for her Ph.D. research, getting struck by vehicles on Malaysia’s Penang Island.
- Since 2019, her group has built three canopy bridges made from repurposed fire hoses to help langurs and other tree-dwelling wildlife safely cross busy roads, with no recorded langur roadkill deaths at the first bridge site since its installation.
- The project combines wildlife conservation with citizen science and environmental education, training volunteers to track langur movements, collect ecological and social data, and work with local communities to reduce human-wildlife conflict.
- Yap says the long-term goal is not simply to build more wildlife bridges, but to foster a broader culture of coexistence and community stewardship for urban wildlife across Malaysia.

Wild animal consumption on the rise in Central Africa, study finds
A new study has shed light on the scale of wild meat consumption across Central Africa. According to research led by CIFOR-ICRAF, a roughly 50% increase in the amount of wild meat being consumed is driven largely by growing demand from rapidly expanding urban populations. Published in the journal Nature, the study analyzed data from […]
In Malaysia, a bridge helps endangered langurs and humans coexist
In Malaysia’s Penang state, conservationists and residents are collaborating to reduce conflict between humans and endangered dusky langurs displaced by urban development and habitat loss. The Langur Project Penang built a canopy bridge to help langurs safely cross a busy road and access more habitat, reducing time spent in residential areas and lowering complaints from […]
How AI could save koalas
A new AI-powered camera system could make road crossings less of a nightmare for koalas. Koalas face multiple threats to their survival including deforestation, urbanization, diseases and bushfires. As humans encroach into their habitats, they are forced to cross roads to move across fragmented forests. Because of this, vehicle strikes have also become a major […]
In Nepal’s capital, invasive flora crowd out native species
Native plants are rapidly declining in Nepal’s capital, Kathmandu, replaced by invasive species historically introduced for ornamental and urban greening purposes, reports Mongabay contributor Bibek Bhandari. Botanist Bharat Babu Shrestha said he has observed traditional medicinal plants like the Indian pennywort (Centella asiatica) slowly vanish from Kathmandu over the past decades, displaced by dense, flowering […]
In India, few are tracking birds colliding with glass in buildings
Bird deaths from collisions with glass structures are a global problem. But in India, conservationists are just beginning to learn the scale of the issue, reports Mongabay India’s Kartik Chandramouli. While humans are taught the concept of glass and its transparency, birds likely perceive the reflection of vegetation or the sky as reality, researchers say, […]
Suspected chemical pollution threatens Nairobi Nat’l Park & key water sources
A suspected chemical discharge is flowing into Nairobi National Park, raising concerns over the vulnerability of a unique protected ecosystem and the growing pressure of urban-industrial activity at its borders. On April 30, 2026, the Kenya Wildlife Service (KWS) reported in a press release sent to Mongabay “abnormal foamy water inflows” entering the park through […]
Singapore’s population of Raffles’ banded langur has doubled
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. In a forest reserve on the edge of Singapore, volunteers spend hours scanning the canopy for a primate they may not see. The exercise points to a simple constraint of conservation in a dense city: most habitats are […]
In Pakistan’s deadly heat, low-cost cooling tools offer a lifeline for pregnant women
Canvas canopies, hand fans, damp cloths and solar reflective paint may not sound like elaborate medical interventions. But in Pakistan’s hottest neighborhoods, they can act as a lifeline for pregnant women and newborns from low-income households. In a recent trial of affordable cooling solutions led by researchers at Pakistan’s Aga Khan University, low-tech interventions were […]
Vaupés River contamination identified near rapidly expanding Amazonian town
- Indigenous people who live downstream from a rapidly expanding Amazonian town on the banks of the Vaupés River told Mongabay the river is contaminated by sewage and has made people sick.
- To verify this, Mongabay obtained water quality studies from the Corporation for Sustainable Development of the Northern and Eastern Amazon, which confirmed that sewage contamination and organic load are above safe limits and may impact public health and the quality of the aquatic ecosystem.
- Traditionally, the Macaquiño community downstream considers the Vaupés River to be a living being with whom they coexist and depend on it for bathing, fishing and human consumption.
- Public authorities in Mitú said the contamination stems in part from the municipality’s poorly constructed wastewater treatment plant, which was built on a flood zone and therefore frequently collapses, dumping untreated sewage into the river.

Americas flyways atlas maps the routes of 89 at-risk migratory bird species
- A newly released “Atlas for the Americas Flyways” tracks the high concentrations of 89 migratory bird species that are at risk of major population decline throughout the western hemisphere. It identifies their breeding grounds, wintering areas and stopover locations.
- This marks the first time these hemispheric migratory routes have been mapped in such extreme detail. Hyper-specific location data aim to provide policymakers, conservationists and others with the necessary tools to make informed decisions about protecting migratory bird species all along their flyways.
- The atlas highlights migratory connectivity — identifying key locations in North, Central and South America. Maintaining the environmental integrity of these places is critical to supporting migratory species and includes many tropical hotspots such as Mexico’s Yucatán Peninsula and the Pantanal wetland in Brazil and Paraguay.
- The atlas will also be of use to researchers trying to understand why a species’ population is declining. It can also help planners mitigate perilous threats by providing geographical data as to where, and where not, to build infrastructure.

Invasives take over native plant spaces in Nepal’s cities
- Native plants are declining in Nepal’s capital Kathmandu, largely due to habitat loss and the spread of invasive species.
- Several invasive plants are dominating ecosystems by blocking sunlight, altering soil and displacing native vegetation.
- Non-native species were introduced historically (since the 1850s) and through globalization. Today, a large proportion of Kathmandu’s plants are exotic, with some becoming invasive and harmful.
- Weak regulation, poor monitoring and preference for ornamental or fast-growing exotic plants in urban planning have worsened the problem, highlighting the need for stronger policies, early control and better institutional coordination.

Compost, racoons and sea turtle predation in Costa Rica
Composting keeps organic waste out of landfills, where it can produce methane, a very potent greenhouse gas. But a new study from Costa Rica’s Guanacaste province finds that when not disposed of properly, organic waste can also trigger a cascade of events resulting in fewer sea turtles. “Normally in Costa Rica we are very used […]
Deadly Indonesia landfill collapse a ‘serious warning’ of systemic failure
A mountain of waste at Indonesia’s largest landfill recently collapsed following days of extreme rainfall that destabilized the massive pile. The tragedy resulted in seven confirmed deaths.
Indonesia court orders release of withheld impact studies on new capital
- Indonesia mining industry watchdog Jatam has won a case at the country’s Supreme Court requiring the government to disclose environmental impact assessments pertaining to two utility water projects at the country’s new capital city site.
- In 2019, then-president Joko Widodo announced he would move the capital of the world’s fourth-most-populous country from Jakarta to Nusantara, a new site surrounded by forests and Indigenous communities on the east coast of Borneo.
- At issue are the Sepaku Semoi Dam and Sepaku River intake, two infrastructure projects at Nusantara that have impacted local Indigenous populations, Jatam said.
- The NGO called the ruling a victory for transparency, but criticized efforts to withhold documents and pointed to a 2008 law as well as Indonesia’s Constitution requiring public access to information.

Hat Yai’s floods are a warning for cities built against nature (analysis)
- Hat Yai’s economy is still struggling to recover from the devastating November 2025 floods, raising fears that repeated disasters could drive businesses and investment away from the southern Thai tourism hub.
- Flood risk is rising due to urban expansion, altered drainage, upstream land-use change and increasingly intense rainfall linked to climate change.
- Decades of costly engineering fixes have failed to keep pace, and without major land-use reforms and nature-based solutions, the city risks locking itself into a cycle of worsening floods.
- This post is an analysis. The views expressed are those of the authors, not necessarily of Mongabay.

Mining rush for critical minerals threatens Amazon land reform settlements
- A survey of mining records found dozens of requests for copper, manganese and nickel targeting land reform settlements in northern Brazil’s Carajás region in the last five years.
- The rush for critical minerals is creating potential “sacrifice zones” of contaminated waterways and declining fish populations in the Amazonian settlements.
- These minerals are vital for cars, batteries and war industries, linking increasing global demand to local Amazon conflicts and poverty, despite a local tax boost.

The power of cities over the seas
- Much of what determines the ocean’s condition is decided on land, where ports control entry, cities regulate ship operations, and municipal buyers shape seafood demand. These urban levers can influence marine outcomes at scale even though they receive far less attention than treaties or national policy.
- Port rules on fuel use, emissions, and safety can compel global shipping companies to change behavior, as access to major trade hubs is too valuable to lose. When several large ports adopt similar standards, their combined weight can shift industry norms across entire maritime corridors.
- Public procurement provides another pathway, with city-run institutions able to influence fisheries through what they choose to purchase. Sustainability standards — or public scrutiny, as seen in Brazil’s school meal controversy — can ripple back through supply chains and alter incentives at sea.
- Philanthropy focused on oceans may find high leverage in supporting city-level actions such as port electrification, data-sharing systems, and procurement reform. By targeting where rules meet markets and infrastructure, urban governance can complement national efforts and deliver practical gains even when international cooperation falters.

Kathy Jefferson Bancroft, guardian of a stolen lake
- For decades, Kathy Jefferson Bancroft challenged the idea that Owens Lake was merely a technical problem, insisting it be understood as a living place with history, meaning, and obligations.
- As Tribal Historic Preservation Officer for the Lone Pine Paiute–Shoshone Tribe, she worked at the intersection of Indigenous knowledge and Western science, pressing agencies to account for longer timescales and deeper responsibilities.
- Her advocacy helped protect sacred sites, resist destructive mining and mitigation schemes, and reshape how land and water decisions were made in California’s Owens Valley.
- Bancroft’s work rested on a simple proposition that unsettled bureaucracies: water is not something to be managed at will, but something that carries memory, limits, and consequence.

Light pollution could worsen allergy seasons, new study suggests
Nighttime light is a well-known hazard for migrating birds and sea turtles. New research suggests it may also pose risks for human health. The study finds that plants exposed to artificial light at night (ALAN) produce pollen for an extended period of time, which is “a major public health issue,” Andrew Richardson, an ecologist with […]
Australia’s land-use squeeze
- Australia’s recent land use change has steadily reduced and degraded native vegetation, shrinking the amount of intact habitat available to wildlife and weakening ecosystem resilience.
- Clearing has been concentrated in productive regions, especially along the eastern seaboard and parts of the north, where agriculture, development, and resource extraction continue to reshape landscapes.
- The biodiversity impacts are not only about area lost: fragmentation breaks habitats into smaller, drier, more isolated patches, making populations more vulnerable to fire, heat, invasive species, and local collapse.
- Conservation tools like protected areas and restoration help, but they struggle to keep pace when habitat loss continues through thousands of incremental decisions across overlapping state and federal systems.

Kirtida Mekani, Singapore’s tree lady, has died, aged 66
Singapore sells itself as an engineered miracle: a dense city that works, where heat, rain, and scarcity are managed rather than endured. Greenery is part of that bargain. Trees soften the concrete and help make the place livable, but they are also a kind of civic language. They signal order, foresight, and the idea that […]
Helping Cape Town’s toads cross the road: Interview with Andrew Turner
- Endangered western leopard toads have lost habitat to urban development in Cape Town, and crossing roads during breeding season adds another danger: getting “squished.”
- Mongabay interviewed Andrew Turner, scientific manager for CapeNature, who discussed underpasses to help the toads safely reach their destinations: ponds for mating and laying eggs.
- Citizen science offers a useful data source, as volunteers record and photograph the toads they help cross the road; “It’s hard for scientists and researchers to be everywhere, but citizenry is everywhere,” Turner says.

Urban sprawl and illegal mining reshape a fragile Amazon frontier
- Ever since Mitú was first established as a settlement in 1935, it has rapidly transformed into an expanding urban town in one of Colombia’s most isolated departments.
- The Amazonian forests, rivers and Indigenous communities who surround Mitú are impacted by urbanization, the overexploitation of natural resources, cattle ranching, illegal mining and timber extraction which have caused deforestation, soil degradation and water pollution.
- Researchers say the construction of a highway from Mitú to Monfort has attracted settlers who cleared land around the road to expand the urban center and develop agricultural production and cattle ranching.
- Mongabay found 10,000 hectares (24,710 acres) of tree cover loss in Mitú since 2014.

Brickmaking keeps eating farmland as Bangladesh misses clean-build goal
- Despite a 2019 mandate to switch to concrete blocks and other alternatives by June 2025, most government projects continued using clay-fired bricks, with only the Ministry of Housing and Public Works fully complying.
- About 7,000 brickfields strip an estimated 9.5 million cubic meters (3.35 billion cubic feet) of topsoil each year, rendering farmland uncultivable for years, while the sector accounts for roughly 3% of Bangladesh’s greenhouse gas emissions due to coal- and wood-fired kilns.
- Concrete alternatives are available, along with government-developed lower-cost options such as compressed stabilized earth blocks made from dredged river sediment, which can cut costs and conserve topsoil, yet their adoption remains limited.
- A 15% VAT on alternative building materials has made them less competitive than traditional bricks, discouraging investment and demand, even as officials plan a new deadline and stricter enforcement to revive the stalled transition.

Rapid urbanization, habitat loss are forcing the snakes out in Dhaka
- The government and private agencies in Bangladesh have rescued at least 351 snakes from various densely populated areas in and around Dhaka city this year. Of the rescued snakes, 319 were venomous.
- A study shows that Bangladesh is home to 89 snake species. Though many of these are non-venomous, a fear of snakebites is widespread among the common people.
- Experts say that excessive and unplanned urbanization is playing a major role in exposing snakes to humans, as the species is losing its habitat due to reduced wetlands and open lands, among other reasons.

Nepal’s cities must plan for resilience and inclusion for the future & nature (commentary)
- The current growth trajectory of Nepal’s cities appears to be unsustainable and unready for the increasing stresses of climate change, an environmental engineer writes.
- Unplanned expansion and the breakdown of the natural/urban interface are diminishing wildlife in this nation, and women suffer disproportionately from the impacts, with an increase in the time spent on water collection of up to 30%, for example.
- But, as this new op-ed argues, “If cities learn from each other, they will see transformed public open spaces, demonstrating how we can turn a climate liability into a community asset.”
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

A ‘Life After Cars’ can provide huge human health and environmental benefits
Sarah Goodyear, Doug Gordon and Aaron Naparstek realized that no one was discussing the many cultural factors that have played a role in humanity’s car dependency, or the negative impacts this reliance on motor vehicles has on human health and the planet. So they started their own show to do exactly that, The War on […]
New riverside lake in Nepal wins hearts, but faces government opposition
- The Bagmati Lake (Bharat Taal), constructed recently in Nepal’s southern Sarlahi district, attracts Nepali and Indian tourists with recreational activities, generating revenue, employment and cross-border tourism.
- The lake, which may have helped improve groundwater levels, soil moisture and crop yields in surrounding areas, has provided habitat for migratory birds.
- However, the fate of the lake hangs in the balance as the country’s anti-corruption court looks into alleged corruption and the lack of environmental compliance during its construction.

Indian megacities are sinking putting thousands of buildings at risk: Study
Parts of Delhi, Mumbai, Chennai, Kolkata and Bengaluru, India’s largest cities, are slowly sinking, mainly due to overextraction of groundwater, according to a recent study, reports Mongabay India’s Manish Chandra Mishra. Researchers used eight years of satellite radar data and found that 878 square kilometers (339 square miles) of land across the five megacities show […]
Makassar women press for water as taps and wells run dry in sweltering Indonesian city
- Located on the coast of Sulawesi Island’s largest city, Makassar, Tallo ward endures high water stress and contamination of local sources with heavy metals and other pollutants.
- Water stress is a well-documented driver of gender-based violence around the world, with extensive correlation established by numerous research studies, and causation in many circumstances.
- In Makassar, women are commonly responsible for ensuring local households are supplied with water, which typically involves hauling more than two dozen plastic containers of water across town.
- In response to these challenges, a grassroots women-led organization has entered direct talks with local political leaders and the municipal water company in a bid to improve access to water for consumption and sanitation.

New arrangements should preserve Nairobi’s much-loved Karura Forest
- In Kenya, an uproar briefly followed the August announcement that the beloved Karura Forest north of Nairobi would no longer be jointly managed by local citizens’ group Friends of Karura Forest and the Kenya Forest Service; the decision has since been reversed.
- The 15-year partnership has restored several indigenous plant species to the Karura Forest, which is also a haven for wildlife such as jackals, bush pigs and small antelopes.
- Previously, the area was threatened by land-grabbers and illegal logging; today, the initiative employs more than 35 staff, who work on forest restoration, security and infrastructure maintenance while some 300 local community members supply thousands of tree seedlings each month for reforestation.

Belém faces its social and natural demons as host to COP30
- Deforestation and the city’s historic shift from rivers to roads led to a massive influx of people into low-lying baixadas, where 57% of residents lack services, such as sewage, and are highly prone to flooding.
- The lack of trees in one of the Amazon’s most revered cities, especially in poor neighborhoods, contributes to projections that Belém will face 222 days of extreme heat by 2050.
- Experts argue that the infrastructure projects being implemented don’t offer sustainable solutions, reflecting a long-term failure to address Belém’s water and sewage crises.

Copper rush pushes Vale to ramp up mining near Amazonian protected areas
- Mining giant Vale has obtained a preliminary license for its Bacaba project, the first step toward doubling its copper production in the Brazilian Amazon over the next decade.
- Experts warn the expansion, near several conservation areas, will worsen deforestation, increase water stress and raise the risk of pollution.
- The global demand for copper is expected to rise by more than 40% by 2040, and almost all of Brazil’s known reserves are in the Amazon.

Climate change and aging drains wreak havoc on Kolkata, India
On Sept. 23, the city of Kolkata in eastern India came to a standstill: The capital of West Bengal state received more than 12% of the city’s average annual rainfall in just 24 hours, some 247.5 millimeters (9.7 inches). The subsequent flooding claimed lives and caused extensive property damage. Scientists say climate change has made […]
As Singapore heats up, pests are seeking refuge indoors
- In the past few years, previously spotless air-conditioned icons of Singapore such as Changi Airport and the Apple Store have experienced infestations and diseases on indoor greenery.
- Experts say the rise in extreme temperatures as the city-state loses forest cover explains the migration of flies, bees, butterflies and rats into cooler indoor environments.
- Singapore’s pest control industry is booming as a result, with the country’s National Environment Agency mandating tougher rules to curb vector-borne diseases.
- Methods used to control pest species are being challenged by animal welfare groups concerned over the growing use of glue traps, which catch protected as well as target species.

Are crows really street smart? Science confirms the genius of corvids (commentary)
- Crows and other corvids exhibit remarkable intelligence — including tool use, problem-solving, memory and even social awareness — challenging long-held assumptions that such cognitive abilities are exclusive to humans or primates.
- Scientific research and experiments, some inspired by popular fables about clever crows, show that these birds understand cause and effect, plan for the future, and adapt their behavior based on context, environment and who’s watching.
- Urban crows thrive due to cognitive flexibility, as shown in an ongoing experimental project in India, which highlights their strategic foraging, memory and ability to learn and adapt in human-dominated environments.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

From counting trees to enhancing climate resiliency, Kampala focuses on its forests
- Recognized as a “Tree City of the World,” Uganda’s capital city of Kampala has set out on a journey to transform its urban forest into a resilient, native-rich landscape.
- What began as a response to falling trees has become a comprehensive environmental strategy tackling health, equity and climate change.
- Kampala has recently expanded its mission to increase green spaces to include biodiversity and connecting wildlife corridors throughout the city.

With nocturnal surveys and awareness building, Sri Lanka steps up to protect its owls
- In Sri Lanka, volunteers and researchers survey owls at night along set routes to mark the International Owl Day that falls on Aug. 4. But what takes more effort is the public educational events to challenge deep-rooted superstitions about owls.
- From the common Indian scops owl (Otus bakkamoena) and brown hawk-owl (Ninox scutulata) to the elusive barn owl (Tyto alba), several owl species persist in Sri Lanka’s commercial capital city despite habitat loss and disturbance.
- In Sri Lankan culture, owls are generally viewed as a bad omen, leading to persecution and eviction from nesting sites, even though species like barn owls provide valuable rodent control, hence being particularly useful in urban settings.
- Practices such as placing hollow coconut trunks in agricultural fields to attract barn owls for natural pest control offer nature-based solutions that could be reintroduced to modern agriculture and beat the stigma around the species.

Deadly monsoon rains in Pakistan made worse by climate change: Study
Unusually heavy monsoon rains that killed more than 300 people across Pakistan since late June were made 15% more intense by human-caused climate change, according to a new analysis. The study, by the international initiative World Weather Attribution (WWA), analyzed rainfall from June 24 to July 3 using observational data and climate models. It found […]

Burning, burying and banning: Indonesia’s cities struggle to manage their garbage
- Indonesia’s garbage crisis is growing, with illegal dumping and unmanaged waste threatening communities, tourism, and ecosystems — as seen in the unsanctioned disposal of nearly 200 truckloads of trash near a popular beach in Yogyakarta.
- Despite a 2008 law banning open dumping, enforcement has long been delayed, but as of April 2025, the central government has officially ordered the closure of 343 landfills and threatened jail time for noncompliant local officials.
- Local governments are scrambling to comply, with some cracking down on illegal dumping, promoting waste sorting, or offering cash incentives — though problems like corruption, poor infrastructure, and public resistance to waste separation persist.
- Experts say lasting solutions require public cooperation, better funding, and consistent enforcement, as Indonesia struggles to change long-standing attitudes and behaviors toward waste management.

Singapore’s regreening is a model for cities everywhere
Singapore has come a long way since the 1880s, when only roughly 7% of its native forests remained. Since the 1960s, when the city-state gained independence, it has implemented a number of urban regreening initiatives, and today, nearly 47% of the city is considered green space, providing numerous benefits to human residents and wildlife, like […]
Deadly landslide and flooding in Colombia and Venezuela linked to rapid urbanization
Heavy rainfall in Colombia and Venezuela caused deadly landslides and widespread flooding in June. A new analysis now points to rapid urbanization, deforestation, mining and overgrazing as having reduced the region’s climate resilience. “The rapid growth of population and informal settlements in areas prone to landslides, particularly in Colombia, puts people and infrastructure at risk,” […]
Indonesia moves to revise sea sand export policy after court ruling
- Indonesia’s Supreme Court earlier this year struck down key parts of a 2023 regulation allowing sea sand exports, citing legal contradictions and environmental risks.
- The annulled policy had reversed a two-decade ban and faced backlash for potentially harming marine ecosystems and coastal communities.
- The government now says it’s revising the regulation, arguing that dredging can benefit ocean health and support domestic infrastructure projects.

The Broadway Malls are a series of small […]
As tree planting gathers pace in Bangkok, urban green spaces still under threat
- Bangkok lags behind global urban green space standards, sparking large-scale tree-planting initiatives across the city.
- Recent research warns that despite these efforts, the city continues to rapidly lose tree cover from its existing green spaces.
- The researchers urge city planners to focus on preserving existing green spaces and mature trees, while also ensuring big-budget tree-planting initiatives prioritize the ecosystem value and long-term survival of their plantings.
- Making such improvements will help the city address issues around access to green space, urban food security and climate resilience, the authors say.

In Yaoundé, fecal sludge flows through ‘Caca Junction’ streets
- In Yaoundé, fecal sludge contaminates neighborhoods where locals say the combination of insufficient sanitation and the costs of septic tank service lead to dumping in the streets.
- The city has just one fecal sludge treatment plant that receives up to double its capacity every day.
- City residents pinch their noses at the smells, while water contamination poses disease risks to local residents.
- Similar situations occur in other African cities that lack sanitation facilities capable of handling the needs of growing urban populations.

Africa’s growing cities are endangering birdlife (commentary)
- In Africa, urban land cover is expected to triple by 2030, and the potential impact on birds and biodiversity is particularly alarming, a new op-ed argues.
- A recently published study used citizen science data from Kenyan and Nigerian bird-mapping projects to uncover insights into how urbanization affects birds, their diversity and ecological functions in these nations.
- “As urbanization has intensified, the variety of bird species and their roles in the ecosystem shrinks, resulting in more uniform communities with generalist species,” author Bello Adamu Danmallam writes.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.

African forum on urban forests calls for greater access to green spaces
- Researchers policymakers, and civil society gathered at the African Urban Forest Forum in Johannesburg to discuss the role of urban forests in African cities.
- The forum centered on how trees can make cities more climate-resilient, providing more equitable access to green spaces, and finding sustainable financing strategy for urban forests.

A Cameroon stadium spurs one community’s fight over ancestral lands
- On the outskirts of Yaoundé, the capital of Cameroon, members of the local Yanda community say the construction of a large multisports complex has left them without their traditional forest lands, where their ancestors were buried.
- The forest previously provided Yanda families with trees, plants and animals for their food and medicine.
- The land, they say, was razed for the construction of the Paul Biya Omnisports Complex, which hosted the 2021 Africa Cup of Nations; today, the stadium stands empty.
- The Yanda community is asking the government for compensation, but the people have no formal titles to their ancestral lands — a common problem for traditional communities in similar situations seeking land rights or compensation for their eviction.

Deadly Botswana rains made more likely by climate change, rapid urbanization

Indonesia families evicted for Jakarta PIK2 project flooded at relocation site
- The peak of the rainy season in Indonesia has caused damage across much of the archipelago, with major landslides in forested uplands.
- On the north coast of Jakarta’s greater metropolitan area, families displaced by an upscale property development were relocated to a site that later flooded.
- A landslide in January killed 26 people in one village in Central Java province, while a married couple were swept away last week in a flash flood in a nearby community.
- Research predicts annual rainfall could increase 10% in volume by 2050 in Indonesia, while incidents of extreme rain could become more frequent.

Illegal sea fence displaces fishers and sparks land scandal near Jakarta
- A property developer installed 30 kilometers (19 miles) of bamboo fencing in the sea near Jakarta, blocking fishers’ access; an investigation revealed it encompassed 280 ocean plots for which title deeds had been illegally issued.
- The fence has forced many fishers to stop working, while coastal farmers have lost their land to the same luxury development; residents also face eviction with no clear alternatives.
- Authorities have sanctioned a handful of individuals from the public and private sectors and started revoking the illegal deeds, but activists are demanding criminal prosecutions against the companies responsible.
- The case highlights weak oversight of Indonesia’s national strategic projects, raising concerns over environmental destruction, loss of livelihoods, and government favoritism toward big developers.

Illegal seabed dredging surges as Indonesia resumes sand exports
- Reports of unauthorized seabed dredging have surged following Indonesia’s decision to resume sea sand exports in 2023, raising environmental concerns and exposing weak marine law enforcement.
- Officials argue that removing sediment helps ocean health and prevents land buildup, but experts and activists warn the policy contradicts marine conservation efforts and lacks transparency.
- Dredging threatens mangroves, coral reefs, and fish populations, with projected losses to fishing communities far outweighing state revenue and corporate profits.
- Experts urge the government to reinstate the export ban, conduct thorough environmental impact assessments, and allocate funds for ecological restoration and affected communities.

Ecology vs. development in Karachi: Interview with photographer Salman Baloch
- Malir, the largest district in Karachi, has long been home to Indigenous Sindhi and Baloch tribes that lived for centuries as communal agrarian societies, dependent on the environment; now, rapid urbanization and development projects threaten the land, water and wildlife.
- Wildlife photographer, activist and writer Salman Baloch has fought against development projects such as the 39-kilometer (24-mile) Malir Expressway and Bahria Town, a 19,000-hectare (46,000-acre) gated suburb of Karachi, both of which pose dire consequences for the region’s wildlife.
- Baloch is also photographically documenting hundreds of bird species that have historically lived in the area.
- Baloch recently spoke to Mongabay about his activism, photography, fears and hopes for the future of Karachi’s wildlife and ecosystems.

Balochistan’s Gwadar city sits at the crossroads of climate and conflict
- A new study examines the links between conflict and climate in Pakistan’s Balochistan province, where extreme weather can be a threat multiplier.
- The port city of Gwadar serves as an example, as local residents have long had grievances against the state, which were exacerbated by recent flooding that killed several people and displaced hundreds.
- Experts highlight the absence of data-driven policies, citing a gap in research that has hindered solutions; they call for investment in data and the inclusion of local people in decision-making and infrastructure planning.

Peru’s modern history of migration and settlement
- Four roads with an enormous impact on rural Peru were built starting in the 1970s, incentivizing migration in the second half of the 20th century to the Amazonian lowlands from the Andean foothills.
- The largest single migratory destination in the Peruvian Amazon is landlocked Iquitos; immigrants arrived there in search of jobs in the oil industry. Currently counting more than 500,000 inhabitants, Iquitos is now the largest city in the Western Amazon.
- The cultivation of coca has had major impacts on the development of Peru’s Amazonian regions. Violent clashes between armed groups searching to dominate the activity have pushed as many as 450,000 people out of their homes.

Construction of Indonesia’s new capital sees port activity crowd out fishers
- Construction of Indonesia’s vast new capital city on the east coast of Borneo has prompted a surge in port traffic in Balikpapan Bay, elevating existing pressures on the belt of mangroves lining the inlet.
- Local villages depend on near-shore fisheries within the inlet, but interviews indicate these communities are struggling to endure the increased port traffic and restrictions to fishing areas.
- District-level officials acknowledged that fishers face diverse challenges as a result of the new capital construction.
- However, they say they will seek redress for the destruction of any of the 16,000 hectares (39,500 acres) of mangroves in the bay area.

Cities are climate solution leaders: Interview with Vancouver’s Gregor Robertson
- 2024 will likely be the hottest year on record, surpassing the heat record set in 2023. The resulting extreme heat waves, floods, droughts and wildfires took a terrible toll in death, global suffering and economic loss.
- The biggest climate change impacts have by far been in the world’s cities. And the world’s cities have responded proactively, becoming climate solution leaders, even as national governments have dragged their feet for nearly three decades.
- If nations and investment banks offered billions in financing to boost climate work now underway in cities, that effort could then be vastly scaled up, said Gregor Robertson, former mayor of Vancouver, Canada, and a special envoy to the Coalition for High Ambition Multilevel Partnerships. This is an exclusive Mongabay interview.

Studies link stronger dengue outbreak in Bangladesh to climate change
- A typical consequence of climate change, drier monsoons with sudden bursts of heavy rain has led to days of inundation and long periods of standing water, creating an ideal situation for breeding mosquitoes, which may be linked to the stronger outbreak of dengue.
- Bangladesh has experienced noticeable changes in the timing and characteristics of its monsoon season. Traditionally occurring from June to August, the monsoon now extends from July to early October.
- Dengue cases have risen dramatically worldwide, with Asia responsible for 70% of reported instances, according to WHO. Researchers indicate that temperatures between 27 and 32 degrees Celsius are optimal for the breeding of Aedes mosquitoes, the vectors of the viral disease.
- As of Nov. 18, the death toll from the dengue outbreak in Bangladesh is 415, with around 80,000 infected, while the country recorded 1,705 dengue-related deaths in 2023.

As global fire risk rises, modern homes become toxic plastic traps
- In the 21st century, petrochemical-based building materials and furnishings have replaced traditional wood, fabric and metal materials in homes worldwide. But plastics are more flammable and release persistent toxic chemicals when burned or exposed to high heat.
- Also over the last 25 years, wildfires have multiplied and intensified due to global warming, and often now jump the wildland-urban interface, burning whole neighborhoods and leaving behind a dangerous toxic home legacy.
- Homeowners whose houses survive such wildfires are often stunned to learn that their homes are a toxic health threat, unlivable and a total loss.
- The multibillion-dollar production and wide-ranging export of plastic building materials and home furnishings, and the dramatic surge in wildfires, has made this a global problem impacting communities in the U.S., China, Australia, Brazil, Canada, Portugal and beyond.

In Kenya, a river restoration initiative pays for itself, and then some
- The water supply for the Kenyan capital, Nairobi, depends on the Tana River, which flows for 1,000 km (620 mi) across the northern part of the country into the Indian Ocean.
- In recent decades, farmers have cut down forests to grow crops on ever-steeper hillsides in the river basin’s upper reaches, damaging water quality.
- The Upper Tana-Nairobi Water Fund was established in 2015, drawing money from corporations and government to pay for watershed restoration and reforestation of this vital resource.
- The fund has enjoyed some success, but obstacles include building up expert knowledge of nature-based solutions by officials in the water sector

As Kathmandu’s birds get used to humans, biodiversity suffers, studies show
- Rapid urbanization in Nepal’s capital, Kathmandu, has led to changes in bird behavior, with urban birds showing increased tolerance toward humans.
- The urban sprawl has caused habitat loss, with the city’s built-up area expanding by 112% between 1989 and 2019, largely at the expense of open green spaces and trees crucial for bird nesting.
- Birds such as the house crow have adapted by using urban materials, such as wires and human clothes, for nesting, while other species have become scarce or disappeared entirely from urban areas.
- Despite government efforts, researchers highlight the need for more native trees in urban areas to preserve bird habitats and promote biodiversity.

Javan fisherwomen lead fight against marine dredging amid fears of damage
- Fisherwomen on the north coast of Java Island are pushing back against plans to dredge sea sand for export, saying they fear it will worsen coastal erosion and harm marine ecosystems.
- Under a 2023 regulation, the government ended a 20-year ban on sea sand exports, sparking backlash despite claims that dredging will occur only in open waters.
- Communities in the north Java districts of Demak and Jepara, where fishing is the primary livelihood, say they are particularly concerned that dredging will severely disrupt their fishing grounds and harm their livelihoods.
- Experts also warn of long-term damage both to marine ecosystems and to the economy, including losses to fishers and the undermining of Indonesia’s marine carbon storage.

Supreme Court decision on saving Kathmandu rivers stirs up heated reactions
- The Supreme Court of Nepal has ruled to extend no-construction zones along major rivers in Kathmandu Valley, sparking varied reactions.
- Environmental activists praise the decision for addressing severe river pollution and encroachment, but the federal government has requested a review due to local opposition.
- The ruling introduces an additional 20-meter (66-foot) buffer zone, which would impact thousands of households, raising concerns about property rights and potential displacement.
- Critics argue the ruling will cause economic hardship and require substantial compensation, prompting the government and local authorities to seek revisions.

Bangkok turns to urban forests to beat worsening floods
- Bangkok is launching city forests to help beat flooding by soaking up excess rainwater runoff.
- A new park slated to open in December will feature 4,500 trees, a floodplain and a weir to slow the flow of water; another newly opened $20 million city forest acts as a sponge during the monsoon season.
- Bangkok is sinking, and fast: according to the World Bank, 40% of the Thai capital could be flooded by 2030.
- The key to solving the city’s flooding problem is to learn to live with water, not to rid the city of water, says one landscape architect helping to launch the urban forests.

Wildlife-rich mangroves suffer as Indonesia ramps up construction of new capital
- The development of Indonesia’s new capital city on the island of Borneo has resulted in clearing of mangrove forests that are home to threatened wildlife such as proboscis monkeys and Irrawaddy dolphins.
- The government has repeatedly claimed that the Nusantara project will be “green,” but experts attribute the ongoing deforestation to a lack of planning by the developers.
- With around 3,900 proboscis monkeys, Balikpapan Bay is a stronghold for the endangered species; but the new capital city’s footprint overlaps with 41% of their habitat.
- The government agency overseeing the project insists it’s doing what it can to mitigate the impacts on wildlife and ecosystems through planning, as well as cracking down on contractors destroying the mangroves.

Conserving & restoring waterways can mitigate extreme urban heat in Bangladesh
- Conserving existing wetlands and restoring urban waterways can be an effective way for urban planners to protect city residents from extreme heat.
- In Dhaka, as in other large cities, paved urban landscapes absorb heat and intensify the risk of heat waves. Areas of cities that are prone to such thermal intensity are known as “heat islands.”
- Urban sprawl frequently fills or covers wetlands and waterways as cities grow.
- Conserving green spaces is important to reducing urban heat and protecting people in cities from extreme heat, but conserving wetlands and waterways is even more effective.

Rio’s grassroots agroforestry sustains birds, bees & communities
- In 2017, some residents of the Rio de Janeiro neighborhood of Governor’s Island spontaneously started tending a neglected garden that originated from a brief corporate event.
- Lacking ongoing governmental or corporate support, the initiative shifted toward agroforestry — a sustainable agroecology system where fruit trees, shrubs, medicinal plants and vegetables are grown in combination to benefit each other — inspiring a dozen more such projects across the island.
- These agroforests have reshaped the urban landscape and now attract an array of fauna, from birds to bees and even fireflies, drawn by the diversity of plant life thriving on improved soils.
- Perhaps most importantly, the agroforests offer free food and medicines to residents in need, plus shade and educational opportunities for the whole community, from schoolchildren to university students and residents.

Uttarakhand villagers thirst for water as tourism, temps & development rise
- An influx of tourists and new residents to Uttarakhand, driven by heat waves and work-from-home options, is straining local resources, particularly water.
- Nearly 12,000 natural springs reportedly have dried up in recent years, with 90% of Uttarakhand’s population depending on these vital water sources.
- Widespread construction for tourism disrupts aquifers and natural water percolation, exacerbating water scarcity and affecting water quality; water sources are further threatened by changing rainfall patterns and rising temperatures.
- Local residents, especially women and marginalized communities, face increased hardships in accessing water amid growing allegations of water diversion by hotels.

Streetlights make tree leaves tougher for insects to eat, Beijing study shows

- In response, researchers, nonprofits and Bangladeshi residents are searching for ways to protect their communities and families.

Bali’s rapid coastal erosion threatens island’s ecosystems & communities: Study
- A recent study revealed that Bali’s coastline shrank from 668.64 kilometers (415.47 miles) to 662.59 km (411.71 mi) between 2016 and 2021 due to human activities and wave circulation, at an average rate of -1.21 meters (3.97 feet) annually.
- The erosion, combined with rising sea levels, threatens the island’s ecosystems, infrastructure and communities, which are economically and culturally significant.
- Despite the erosion, there was a net land increase of 1.25 km2 (0.48 mi2) due to land reclamation and infrastructure development, though these efforts also posed environmental risks.
- The study highlights the need for integrated coastal management to balance environmental protection with the needs of coastal communities.

Photos: Exploring Mexico City’s Aztec-era farms, the chinampas
- Chinampas are part of an agricultural system developed during the Aztec Empire in shallow lakes or marshes in the southern valley of what is today Mexico City.
- The system consists of elevated, narrow platforms used as fields that are surrounded by water canals, and is considered one of the most intensive and productive farming systems ever developed.
- However, for decades, chinampas have faced increasing threats due to urbanization, the overexploitation of water resources, water contamination and unregulated tourism, as well as the growing rejection of chinampa culture by traditional farmers and the loss of ancestral knowledge.

Black days for black kites in Bangladesh’s growing capital city
- The sight of soaring black kites has become a rare sight in Dhaka city, which has become urbanized in an unplanned manner at the cost of wetlands and numerous mature trees.
- In the last two months, at least 35 sick black kites were rescued from several Dhaka localities. Experts are concerned as the population of the bird has dropped drastically in the city in recent years.
- The absence of large trees close to the black kites’ foraging sites forces the birds to undertake long trips, consuming extra energy between roosting times.
- Unfavorable weather, such as heavy rainfall and heat waves, also hampers parent black kites’ feeding habits, reducing food availability and impacting breeding success.

Trial begins for Mother Nature Cambodia activists on conspiracy charge
- Ten environmental activists face up to a decade in prison as their trial gets underway in Cambodia on charges of plotting against the government.

Borneo and Sumatra megaprojects are carving up clouded leopard forests
- Massive infrastructure projects currently underway on the Southeast Asian islands of Borneo and Sumatra are set to severely erode forest connectivity across key habitats of the Sunda clouded leopard.
- Two major highway networks and the relocation of Indonesia’s capital city to Borneo will further fragment the domain of the arboreal predator that has already experienced steep population declines in recent decades due to the expansion of oil palm and poaching.
- Experts say the findings will help to target conservation actions, but they add that road design standards and development planning processes remain woefully inadequate in the region.
- The authors call for improved development strategies that seriously consider sustainability and include data-based environmental assessments and mitigation measures, such as wildlife crossings and avoidance of sensitive ecosystems.

Uttarakhand limits agricultural land sales amid protests & tourism development
- Following widespread protests, Uttarakhand’s Chief Minister Pushkar Singh Dhami has issued orders to district magistrates to deny permission to sell agricultural lands to those outside the state.
- With just 14% of its land designated for agriculture and more than 65% of the population relying on agriculture, calls for legislation to safeguard residents’ land rights have intensified.
- With a lack of comprehensive, updated land records, monitoring the usage of farmlands for nonagricultural purposes has become challenging.
- Lack of employment opportunities and resources as well as shifting weather patterns and climate change have pushed numerous farmers to sell their land holdings.

Circular solutions vital to curb enviro harm from cement and concrete
- Concrete is ubiquitous in the modern world, but building cities, roads and other infrastructure and more comes with an environmental cost. Cement and concrete production is responsible for significant pollution, human health impacts and vast amounts of climate-fueling emissions.
- Manufacturing cement is particularly problematic as the chemical process used to make it produces nearly 8% of global carbon emissions. Experts also underline that demand for the mined and quarried aggregate materials used to make concrete, such as sand, is responsible for biodiversity and ecosystem harm.
- Demand for cement and concrete is set to grow, especially in developing countries to improve infrastructure and living standards. Experts say that solutions reigning in the sector’s environmental footprint are vital, especially curbing greenhouse gas emissions that could absorb a major chunk of our remaining carbon budget.
- Solutions to address these challenges include a suite of technological advances, material changes, improved resource efficiency, and circular economy approaches. Some specifics: electrifying cement kilns, low-carbon concrete, carbon capture, and bio-architecture utilizing natural building materials.

In highly urbanized Japan, city farmers are key to achieving organic goal
- The Japanese government aims to convert at least 25% of all its farmland to organic by 2050, a significant jump from just 0.5% in 2020.
- Researchers found that urban and semi-urban farmers in Tokyo tend to adopt environmentally friendly practices more often than rural farmers, in response to a more environmentally conscious populace, a greater number of organic food stores and restaurants, and freedom from pressure to conform with farming practices in rural communities.
- Japan’s urban farmers are also more likely to diversify their business, such as by engaging in direct sales and creating hands-on farming events or volunteer opportunities, strengthening their ties with the local community.
- Despite positive steps, agricultural land in Tokyo continues to shrink, mirroring a trend in declining biodiversity. Advocates say continued efforts will be needed to preserve and make the best use of the capital’s urban farms.

Ecological overshoot is a ‘behavioral crisis’ & marketing is a solution: Study
- The current ecological crises facing our planet are extensively the result of a human behavioral crisis, according to a 2023 paper appearing in the journal Science Progress. The paper cites economic growth, marketing and pronatalism as key drivers of human “maladaptive behaviors” resulting in ecological overshoot.
- The authors, three of whom have affiliations with the marketing industry, argue that behavior manipulation through the use of marketing, media, and entertainment could go a long way toward solving our environmental problems. It “may just be our best chance at avoiding ecological catastrophe,” they write.
- Experts interviewed by Mongabay say they agree that human behavior contributes to the environmental problems faced today, but they disagree with the paper’s focus on behavior manipulation of individuals as a leading solution, which risks shifting focus from the urgent need for broader systemic changes, such as decarbonization.
- “The most effective and scalable behavior change interventions often target social, physical and economic factors rather than individuals directly,” notes behavioral scientist Kristian Steensen Nielsen.

To save topsoil & reduce pollution, Bangladesh moves toward alternative bricks
- Bangladesh plans to move from traditional fuel-burned bricks to alternative bricks to save agricultural topsoil and reduce air pollution.
- As part of the initiative, the government has already set a target to use alternative bricks made from concrete blocks for all government works starting this year.
- The environment department estimates that the nation’s 7,000 or so brickfields currently use 3,350 million cubic feet of topsoil or clay annually as a raw material to produce around 23 billion bricks.
- Meanwhile, the Bangladesh Housing and Building Research Institute (HBRI) demonstrates through its research and development how the nation could save an enormous amount of topsoil by utilizing alternative building materials and bricks in place of the conventional bricks made from agricultural topsoil, which is necessary to maintain soil fertility.

Controversy brews over proposed dam on Kathmandu’s Bagmati River
- A proposed dam on Kathmandu’s Bagmati River aims to collect rainwater during the wet season and release it in the dry season to rejuvenate the river, but skeptics question its viability and safety.
- Concerns include environmental impact, potential destruction of trees, pollution and the risk of dam failure in earthquake-prone Nepal.
- Political, ecological and community-related questions remain unanswered, with some advocating for alternatives and further analysis before proceeding.

Risky development in Uttarakhand: Interview with environmentalist Ravi Chopra
- Ravi Chopra, an esteemed environmentalist based in Uttarakhand, is renowned for his dedicated efforts to preserve natural resources within the Himalayan region.
- In 2019, the Supreme Court appointed Chopra as chair of a committee to review the controversial Char Dham highway construction project; he later resigned after construction proceeded despite the committtee’s findings that the project could pose significant risks to the ecologically fragile region.
- The Char Dham project drew international attention in November 2023, when a segment of a tunnel collapsed, trapping dozens of workers for 17 days.
- In a recent interview with Mongabay, Chopra discussed the environmental risks and hazards of development in Uttarakhand.

Study: Indonesia’s new capital city threatens stable proboscis monkey population
- A recent study warns that the ongoing construction of Indonesia’s new capital city on the island of Borneo could destabilize the population of endangered proboscis monkeys currently thriving in the area.
- President Joko Widodo has characterized the development as green and with a minimal environmental impact, but concerns have arisen over the potential threat to the nearby Balikpapan Bay mangrove ecosystem that’s home to proboscis monkeys and other threatened wildlife.
- Scientists have advocated for sustainable development practices and emphasized the importance of respecting local biodiversity while constructing the new city, Nusantara.
- Their recommendations include legal protection for affected areas, habitat restoration, and collaboration with local stakeholders to mitigate the environmental impact.

Livelihoods at stake as Lake Victoria’s papyrus swamps come under pressure: Photos
- The papyrus swamps at the edges of Lake Victoria in East Africa have for generations provided a livelihood to communities living here.
- While some harvest reeds to make into mats, baskets, and handicrafts, others catch the plentiful fish that nurse in the shelter of the reedbeds.
- The swamps are also home to birds that have become specialized to live amidst the papyrus reeds in a narrow geographic range, while the reedbeds serve as filters taking up nutrients and retaining sediment — in the process also allowing carbon storage through the buildup of significant detritus and peat deposits.
- However, development pressure for new resorts and farmland is putting this ecosystem under threat, while the introduction of the Nile perch here in the 1950s has devastated native fish species.

Communities on troubled Java river mold future from plastic waste
- The Ciliwung is a highly polluted river running from Mount Pangrango in western Java, through the city of Bogor, before ending in the bay north of Jakarta, Indonesia’s capital.
- Since 2018, Bogor Mayor Bima Arya Sugiarto has overseen an initiative to rehabilitate the river, which was awash with plastics and dangerous levels of fecal coliform bacteria.
- Bogor is among more than 50 global cities participating in the Plastic Smart Cities, initiated by WWF to help eliminate plastics from nature.

Why the Amazon’s small streams have a major impact on its grand rivers
- An unprecedented time-series study in the basin of the Tapajós River, a major tributary of the Amazon, assesses the level of degradation of small rivers threatened by agribusiness expansion.
- Researchers from several universities will assess the conservation status of 100 streams spread between the municipalities of Santarém and Paragominas, at the confluence of the Tapajós and the Amazon, which were first analyzed in 2010.
- The impact of dirt roads and their network of river crossings, which causes sediment load, siltation, erosion and changes in water quality, was one of the factors that caught researchers’ attention in the initial time-series study.
- Experts say that local development models should ideally start from water to land, rather than the other way around, given the importance of water for the rainforest, its biodiversity, and the inhabitants who depend on both.

Study: Singapore biodiversity loss is bad — but not as bad as previous estimate
- A recent study concludes that Singapore has lost 37% of its species since the construction of the city began in 1819.
- While high, the figure is significantly lower than a 2003 estimate of 73% species loss during the same period, a difference the authors of both the current study and the 2003 estimate attribute to more advanced statistical modeling.
- Although 99% of Singapore’s forests have been wiped out, extinction rates have leveled off and all remaining primary forest is protected, which researchers say presents an opportunity to conserve remaining species and work to reintroduce animals that have gone locally extinct.

Discriminatory U.S. housing policies still affect bird sightings 90 years later
- Researchers have found far less data on bird sightings in neighborhoods impacted by discriminatory housing policies in the United States since the 1930s.
- Even with the rise of digital citizen science platforms like eBird in the last two decades, the information gap on bird species between wealthy and impoverished areas has gotten much worse.
- This legacy of environmental injustice in the U.S. prevents ecologists from having a reliable picture of biodiversity in major cities.

The Amazon’s archaeology of hope: Q&A with anthropologist Michael Heckenberger
- A professor at the University of Florida, Michael Heckenberger has been visiting and studying Indigenous peoples at the Upper Xingu River for decades and says the Amazon is already facing its tipping point: “It’s a tipping event.”
- In this interview for Mongabay, he tells how he and his colleagues have been practicing an “archeology of hope” — helping the Indigenous peoples in the region to prepare for climate change, using ancestral knowledge pulled out from archaeological research.
- “It should be the default, not the exception, to assume that there were Indigenous people living or dwelling in some way on almost every inch of Brazilian land,” he says about the marco temporal thesis, which aims to limit new Indigenous territories, now being discussed in Brazilian Congress.

Indonesian islanders draw line in sand as Dubai-style reclamation nears
- Residents of the island of Lae-Lae off the Makassar seafront in eastern Indonesia are stepping up their opposition to a major reclamation project conceived in 2009.
- The community has staged seven demonstrations this year to press their opposition to the ongoing development, which they warn will decimate their near-shore fisheries.
- The provincial government has previously said the island’s population will not be required to move, and that Lae-Lae will derive economic benefits from the development.

Tien Hai Nature Reserve latest battleground in Vietnam’s push for development
- In April, the government of Vietnam’s Thai Binh province quietly issued a decision to remove protection from 90% of Tien Hai Nature Reserve, which forms an integral part of the UNESCO-recognized Red River Delta Biosphere Reserve.
- After environment activists publicized the decision last month, public backlash prompted officials to pause plans to develop a resort in the degazetted area — at least for now.
- The project is just one of several recent cases in which the country’s protected wetlands and forests have been threatened by development projects.

Bangladesh to produce lithium batteries, electric vehicles to cut emissions
- According to Bangladesh’s nationally determined contribution (NDC) toward reduced emissions under the Paris Agreement, the transport sector accounts for 9% of total greenhouse gas (GHG) emissions in Bangladesh. The country has proposed 3.4 million metric tons of CO₂ equivalent GHG emission reduction by 2030 in the transport sector.
- To facilitate policies aimed at reduced emissions, such as tax holidays and financial incentives for local manufacturing of electric cars and the expansion of technology and infrastructure for vehicles that need less fuel, Bangladesh has formulated the Automobile Industry Development Policy 2021.
- It is hoped that by encouraging the uptake of electric vehicles — among two-, three- and four-wheelers — Bangladesh can achieve its goal.
- The production of locally made lithium batteries and transformation of the sector through electric vehicles will aid the country’s emission reduction plan, industry insiders say.

Nepal’s BP Highway threatens endemic, critically endangered lizard
- The dark sitana, a lizard endemic to a town in Nepal, is critically endangered by the loss and degradation of its habitat due to the BP Highway and unplanned urban development.
- Researchers are studying the ecology and threats of the dark sitana and conducting conservation outreach to raise awareness and support for its protection among local communities and stakeholders.
- The dark sitana is understudied and neglected by the government and needs more research and conservation efforts to prevent its extinction, researchers say.

Elders call for Indigenous cultural preservation in new Indonesia capital
- The Balik and Paser Indigenous communities worry that traditions risk becoming supplanted by Indonesia’s new capital city on the east coast of Borneo.
- More than half of the new capital estate could be considered customary territory, according to the Indigenous Peoples’ Alliance of the Archipelago.
- Indigenous elders said that if rituals are to be conserved, then the customary territories must be maintained, while the local government says it is working on programs to uphold local culture.

São Paulo students plant mini-forests on school grounds as urban oases
- Four thousand students planted nearly 10,000 trees on public school grounds in the city of São Paulo, Brazil, in 2022, and another eight mini-forests will be planted in 2023.
- The project, created by the NGO formigas-de-embaúba, could be implemented at 650 public schools in the city, according to a MapBiomas study.
- Guarani leaders from the Jaraguá Indigenous Territory participate in the project, which was inspired by Indigenous knowledge and cosmology.
- Specialists see mini-forests at schools as a strong strategy for creating a democratic network of “cooling places” or urban oases in the face of intensifying global warming.

On burning-prone Borneo, planners work to fireproof Indonesia’s new capital
- The developers of Indonesia’s new capital city, Nusantara, have begun preparations to protect the site from the threat of wildfires and smoke pollution.
- City planners are to launch drones to monitor the estate for wildfires and hope to operate a dedicated fire brigade from next year.
- Nusantara faces lower wildfire risks owing to its east-coast location and distance from Borneo’s flammable peatlands, but officials nonetheless stress the need to build an early-warning system for wildfires around the site.

Opposition grows to Indonesia’s resumption of sea sand exports
- Marine conservation and fisheries activists in Indonesia are pushing for exports of sea sand to be scrapped, saying the activity harms the environment and community livelihoods.
- Indonesia imposed a ban on exports of dredged sea sand in 2003, but reversed the policy through a regulation issued in May this year.
- Activists say the policy directly threatens the future of Indonesian fishing and coastal communities in the world’s largest archipelagic nation, where millions of people are dependent on fishing for their livelihoods.
- Others say the resumption of exports will benefit foreign interests, including Singapore, which has expanded its land area by 20% thanks largely to Indonesian sand, and China, which is building artificial islands to shore up its claims to parts of the South China Sea.

Five ways to increase tree cover in cities (commentary)
- As cities in the U.S. and other nations suffer from current heat waves, one proven way to cool urban areas and clean the air is by planting trees.
- The solution sounds simple but there are numerous barriers to increasing tree cover in urban areas, from high mortality rates to capacity limitations within municipal forestry, parks, and recreation departments.
- “Trees are as integral to city infrastructure as sidewalks and power lines,” a new op-ed that shares useful resources says: people need improved information and tools to advocate for, plan, and implement urban tree conservation, maintenance, and planting activities to support cities’ future livability, equity, and public health.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Indonesian architect presses vision for low-cost homes from nature
- Architect Yu Sing is among a number of notable Indonesian architects prizing natural materials and traditional techniques as part of contemporary design.
- For more than a decade, Yu Sing’s Bandung-based Studio Akanoma has built projects great and small, from showpiece convention spaces to communal bamboo kitchens for women farmers.
- In 2009, Yu Sing published a book, Mimpi Rumah Murah, setting out his vision for affordable homes using locally available natural materials.

Bangladesh’s ‘bird restaurant’ serves up snacks with a side of conservation
- Shomour Kumar Ghosh, a sweetmeat maker living in western Bangladesh, began feeding a flock of mynas gathered outside his shop in 2012.
- Since then, he hasn’t stopped, and today feeds an estimated 2,000-2,500 of the birds each morning, at a cost of around $28 daily.
- Ghosh’s “bird restaurant,” as it’s become known, is one of several efforts initiated by individual bird lovers across Bangladesh trying to do their part for avian conservation.
- Ghosh’s love for birds and his feeding efforts have been widely lauded across Bangladesh, and in 2020 he was awarded the best “Bird Lover” in the country by the Forest Department.

Not so fast, experts warn as Dhaka tries to clear the air with car tax and bus ban
- With one motor vehicle for every one of its more than 20 million inhabitants, Dhaka has grown into one of the most polluted and congested cities in the world.
- Policymakers want to change this with a pair of proposals: Slapping a carbon tax on multiple car ownership, and removing aging buses and trucks from the city’s roads.
- However, experts and studies point out that the biggest contributor to the city’s dire air quality isn’t vehicle emissions, but the burning of straw for brick kilns.
- They also warn that abruptly slashing the city’s bus fleet would severely impact residents, for whom the bus network is the main mode of transportation.

Strengthening crops with insect exoskeletons? Study says yes, by way of the soil
- Supplementing soil with insects’ cast-off outer skin after a molt can help increase plant biomass, the number of flowers, pollinator attraction, seed production, and even resilience to insect herbivore attacks, according to researchers.
- Farmers are already using insects, in particular the black soldier fly, for livestock feed and waste reduction, and this new use could help the transition to a more sustainable and circular agricultural system, scientists say.
- Along with further investments in research and development, a higher uptake in insect farming practices, by both small and industrial farmers, will improve for boosting crop productivity within circular agriculture.

For urban poor in Global South, nature-based solutions have always been a way to get by
- Nature-based solutions are increasingly being seen as a way of providing societal benefits and conserving biodiversity.
- Informal settlements, which lack necessary infrastructure and are often at the forefront of climate change and other natural disasters, can benefit from nature-based solutions and improve residents’ quality of life.
- A recent study explored the different forms of nature-based solutions in practice in Southeast Asia and the Pacific, their benefits and disadvantages, and identifies factors that make them successful.
- While the term “nature-based solutions” has recently been popularized in the Global North, researchers note that communities in many parts of the world have engaged in these practices for centuries.

Experts, activists unite to blast Indonesia’s U-turn on sea sand exports
- Indonesia will resume exporting sand dredged from the sea, commonly used in reclamation projects, ending a 20-year ban.
- Environmental activists and marine experts have criticized the policy, saying the resumption caters only to business interests and fails to consider the damage to marine ecosystems and fishing communities.
- The government says it will only allow dredging on seabed areas where sediment from land runoff has accumulated, adding that this will also help ease ship traffic.
- But critics say these arguments are meaningless and a form of greenwashing, and have called for widespread public opposition to the policy.

Soil carbon in urban parks important in fighting climate change, study shows
- A recent study shows that urban parks and green spaces throughout the world have a similar amount of carbon stored in their soils as in natural regions close to cities, which means urban green spaces can be important to global carbon sequestration and mitigating the potential effects of climate change.
- Soil microbes in urban green spaces play a vital role in carbon storage, but that carbon is also vulnerable to loss through microbial respiration in an increasingly warmer world; researchers emphasize the need for greater understanding of the soil microbiome in urban policies and planning.
- For context, Suriname has 93% forest cover nationwide and is often referred to as the world’s “greenest” country — but the capital city, Paramaribo, lacks a structural approach to urban greenery.
- Researchers conducted a project to promote a greener and more livable Paramaribo, with the aim of mitigating the effects of climate change and raising awareness among citizens.

Indonesia’s new capital ‘won’t sacrifice the environment’: Q&A with Nusantara’s Myrna Asnawati Safitri
- The ongoing development of an entirely new capital city from the ground up in Indonesia has alarmed environmental and Indigenous rights activists, who have warned of both deep ecosystem and social impacts.
- The government has justified the plan to move the nation’s capital from Jakarta, on the island of Java, to Indonesia Borneo as a way of ensuring a greater share of development beyond the country’s western islands.
- Mongabay has already reported on the risks to the wider Bornean region and the additional pressures on marine ecosystems that are a biodiversity haven.
- In response, Myrna Asnawati Safitri, the deputy for environment and natural resources at the government agency overseeing the development, reached out for an exclusive interview where these and other thorny questions were addressed.

‘Alarming’ heat wave threatens Bangladesh’s people and their food supply
- Temperatures across Bangladesh have hit record highs as the country swelters in the heat wave currently sweeping across much of Asia.
- Dhaka recorded its highest temperature in six decades this month, at 40.6°C (105.1°F), with meteorologists warning that heat waves like this are becoming more common.
- The heat also threatens the country’s all-important rice crop, with the government advising farmers to ensure sufficient irrigation to prevent heat shock to their plants.
- With the heat now easing, a new fear has emerged: Cooler temperatures signal the start of the monsoon, which, in the northeast region of Bangladesh often means floods that can also destroy rice crops.

To build its ‘green’ capital city, Indonesia runs a road through a biodiverse forest
- A new toll road in Indonesia’s East Kalimantan province is under construction to improve access to the interior of Borneo, including to the nation’s new capital city, Nusantara.
- Construction of the road, however, poses immediate environmental risks, as the route cuts through a forested area with high conservation value that connects the Sungai Wain protected forest, coastal mangroves, and Balikpapan Bay.
- Prior to road construction, the integrated forest and coastal ecosystem supported populations of orangutans, sun bears, proboscis monkeys and Irrawaddy dolphins.
- Conservationists say the construction of this toll road belies the Indonesian government’s claims that the development of the new capital will be green and sustainable.

Reconnecting ‘island habitat’ with wild corridors in Brazil’s Atlantic Forest
- This three-part Mongabay mini-series examines grassroots forest restoration projects carried out within isolated island ecosystems — whether those islands are surrounded by ocean as on the Big Island of Hawai‘i, or cloud forest mountaintop habitat encircled by lowlands in Costa Rica, or forest patches hemmed in by human development in Brazil.
- Reforestation of degraded island habitat is a first step toward restoring biodiversity made rare by isolation, and to mitigating climate threats. Though limited in size, island habitats can be prime candidates for reforestation because extinctions are typically much higher on isolated habitat islands than in more extensive ecosystems.
- Scientists mostly agree that the larger the forest island habitat, the greater its biodiversity, and the more resilient that forest system will be against climate change. Forests also store more carbon than degraded lands, and add moisture to soil and the atmosphere as a hedge against warming-intensified drought.
- The projects featured in this series are small in size, but if scaled up could become big forest nature-based climate solutions. In this third story, the NGO Saving Nature works to create wild corridors to reconnect fragmented patches of Brazil’s Atlantic Forest.

Human migration to Nepal’s tiger capital adds to conservation challenges
- Chitwan district in central Nepal is home to the eponymous national park that’s come to symbolize the country’s success in growing its tiger population.
- But the district’s human population is also growing, at a rate far higher than the national average, driven by migrants seeking better health services and other urban amenities.
- Conservationists have raised concerns that the growing human presence in the area will pose additional challenges to conservation efforts and put a strain on natural resources such as forests, rivers and land.
- Some warn of an increase in human-tiger conflict, especially involving migrants who don’t share the same traditional knowledge that Indigenous residents have of coexisting alongside the big cats.

As Indonesia’s new capital takes shape, risks to wider Borneo come into focus
- Indonesia’s plan to build its new capital city on an expiring logging concession in eastern Borneo has sparked concerns among environmental and human rights observers about the larger eco-social impacts to the rest of the island.
- The administration of President Joko Widodo, who made the decision and will leave office next year, has made glowing promises of a green and sustainable development: claiming minimal forest clearance, respect for Indigenous and local communities’ rights, and a net-zero carbon emission design.
- Mongabay visited the site of the project last October to see its progress, observe firsthand some of the earliest impacts from the construction of the city and supporting infrastructure, and speak with the people most likely to be affected.
- Clearing of mangroves and high-conservation forest areas, land conflicts with Indigenous communities, and potentially large-scale displacements are already happening, calling into question whether the $34 billion project’s benefits will outweigh its downsides.

In Chile, drought and human expansion threaten a unique national park
- La Campana National Park in Chile is home to threatened species of plants and animals, many found nowhere else.
- The region has been suffering a 12-year drought, and in spite of rains this year, experts say it’s too early to say whether the climate trend has been reversed.
- The park also faces pressure from expanding farmland and urbanization, including the conversion of native vegetation to fruit monocultures, and the encroachment of domestic animals that can spread disease to wildlife.

Another winter of discontent as Kathmandu braces for deadly air pollution
- As winter sets in, residents of Kathmandu are bracing for worsening air pollution levels that can exceed by a hundredfold the safe limit prescribed by the WHO.
- The sources of the pollution are both local — vehicle exhaust fumes and burning of garbage — and from further afield, including firecracker residue from festivities in neighboring India.
- A recent study says these combine to give Nepal the highest death rate from chronic lung disease of any country — a problem that experts say the government has repeatedly failed to recognize.

Mangroves and wildlife in Bornean bay at risk from Indonesia’s new capital
- Experts and activists say the construction of Indonesia’s new capital city upstream of Balikpapan Bay on the island of Borneo fails to mitigate against damage to the marine ecosystem.
- The stretch of coast between the bay and the mouth of the Mahakam River is packed with mangroves, which host a rich diversity of marine and terrestrial life, including proboscis monkeys and Irrawaddy dolphins.
- The government has said the construction of the new capital, Nusantara, will include retaining a large swath of mangrove forest, but zoning details show most of it won’t be protected against development.
- The $33 billion planned city will in 2024 take over as the Indonesian capital from Jakarta, and its full construction will be completed by 2045, according to the government’s plans.

Cambodia’s elites swallow up Phnom Penh’s lakes, leaving the poor marooned
- Lakes in Phnom Penh are fast being filled in and parceled off as prime real estate to wealthy and politically connected individuals.
- Families who have for generations fished and practiced aquaculture on the lakes and surrounding wetlands face eviction and the loss of livelihoods.
- At the same time, experts warn that filling in these natural rainwater reservoirs risks exacerbating flood intensity and damage in the Cambodian capital.
- This story was supported by the Pulitzer Center’s Rainforest Investigations Network where Gerald Flynn is a fellow.

Mangrove restorers in Haiti bet on resilience amid rising violence
- Haiti is one of the most deforested countries in the world today, with its mangroves in particular now dotting just 30% of its coastline, much of it in thin, fragmented pockets.
- The main threat to the mangroves is the cutting of the trees to produce charcoal, an important fuel for cooking in a country where only a quarter of the population has access to electricity.
- Several mangrove restoration projects have been initiated over the years, and many abandoned due to waning community interest, natural disasters, or poor planning.
- More recently, rising rates of violence have prevented restoration teams from going to the field and coordinating with one another, but some are hopeful that communities remain receptive to mangrove restoration despite all the other hardships they’re experiencing.

In Kathmandu, when the falcon’s away, pigeons come out to play. And poop
- Once treated as pets, Kathmandu’s pigeons have now become a menace.
- With their population growing unchecked, the birds invade homes, soil buildings, and frequently carry parasites.
- Ornithologists attribute the pigeon population boom to the decline in urban birds of prey, such as peregrine falcons that once kept pigeon numbers under control.
- The long-term solution to the problem, they say, is to identify and fix the factors that have pushed the raptors out of the city.

Engineers bet on a miracle to bring Nepal’s holy river back to life
- Officials in Nepal hope to start reviving the sacred Bagmati River that runs through Kathmandu with the help of a rainwater reservoir.
- The Dhap Dam is expected to go into operation in October, when it will start providing water for the Bagmati during the dry season — a period when the river can shrink to just 3% of its monsoon peak.
- Unlike most other rivers in Nepal, the Bagmati doesn’t flow from the Himalayan icepack, and instead is fed by springs that, in recent decades, have dried up as a result of urbanization.
- But with the river so polluted that a study declared it “not suitable for aquatic life,” even those behind the project acknowledge that the best they can hope for is to improve its condition, not bring it back to life.

Urban farming in Indonesia addresses food needs and climate crisis
- Grassroots initiatives in several Indonesian cities have sprung up aimed at achieving food security through urban and family farming.
- Proponents say this is a great way to diversify food variety and cushion the impact of rising food and commodity prices.
- They also tout its ecological benefits, including lower emissions and healthier soil than with commercial farming.

Building Indonesia’s ‘green’ new capital could see coal use surge (analysis)
- Indonesia is planning to construct a new capital city, known as Nusantara, in the Bornean province of East Kalimantan.
- Authorities promote Nusantara as a “green city,” but discussions of the city’s carbon footprint overlook key factors, notably the use of coal to manufacture the building materials required to construct a completely new city.
- With the new city being built in the country’s coal-mining heartland, coal is the most likely energy source for such manufacturing, putting Indonesia’s emissions reduction targets at risk, as well as casting doubt on the green commitments of funders like Japan and China.

For residents of Jakarta’s port district, coal is the neighbor no one wants
- Residents, officials and experts blame dust from a coal storage facility in Jakarta’s port district for a spate of health problems in a neighboring community.
- Children in Marunda ward have been hit particularly hard, suffering from eye and skin problems and respiratory infections, in a city already notorious for its dirty air.
- City authorities inspecting the facility run by KCN, a public-private joint venture, have found several violations and revoked the company’s environmental permit.
- While KCN has offered to provide residents with free medical checkups, it has not acknowledged a link between its operation and residents’ health problems.

Turkey’s authoritarian development ignores planetary boundaries
- Turkey, an increasingly autocratic country since Recep Tayyip Erdoğan and his AKP political party came to power in 2002, was the very last G20 nation to ratify the Paris climate agreement, doing so in October 2021. It has failed so far to take meaningful action against the steady increase of its greenhouse gas emissions.
- Turkey may also be exceeding limits to many of the nine planetary boundaries critical to the survival of civilization. In addition to unregulated carbon emissions, experts are concerned over the nation’s worsening air and plastic pollution, altered land use due to new mega-infrastructure projects, and biodiversity harm.
- For the past two decades, Turkey’s economic growth has been based on carbon-intensive sectors — including fossil fuel energy, transportation, construction, mining and heavy industry — all heavily supported by the state via subsidies, questionable public-private partnerships, and lax environmental laws.
- Turkish president Recep Tayyip Erdoğan’s authoritarianism has undermined checks and balances which might otherwise enhance environmental governance. As activists and academics criticize the lack of transparency regarding environmental data, they face rising governmental pressures and repression.

World’s worst air pollution slashes 7 years off life expectancy in Bangladesh
- Air pollution in Bangladesh is the worst in the world, a new study shows, reducing the average Bangladeshi’s life expectancy by 6.7 years.
- Another study estimates there were 24,000 premature deaths as a result of air pollution in the country’s capital, Dhaka, from 2005 to 2018.
- Brick-burning kilns, vehicle exhausts, various industries, open waste burning, and large-scale construction work are key sources of air pollution, according to the Department of Environment.
- The draft Clean Air Act 2019 has yet to be enacted into law, which proponents say is needed to boost institutional action to tackle the air pollution problem.

‘Lost’ Amazonian cities hint at how to build urban landscapes without harming nature
- Archaeologists have discovered the remains of a Pre-Columbian urban settlement that spans more than 4,500 square kilometers (1,737 square miles) in Bolivia’s Llanos de Mojos region, in the Amazon rainforest.
- This is the latest proof that large, complex urban societies existed in the Amazon before the arrival of the Spanish, challenging the idea that the rainforest was always a pristine, untouched wilderness.
- Some experts say we could learn from these Indigenous urban planning strategies, which, with a sophisticated land and water management system, show us how cities and the rainforest once co-existed without degrading the environment.

9m deaths a year from pollution, the ‘largest existential threat’ to humans
- A new report has found that pollution is responsible for 9 million premature deaths per year, the majority of them caused by air pollution.
- While deaths associated with household pollution and water quality have decreased, deaths related to industrialization and urbanization have increased.
- It’s estimated that lead and other chemical pollutants are responsible for about 1.8 million deaths, but the authors say this is likely to be an undercount.
- The authors argue that more needs to be done to address the issue of pollution, which would also help mitigate the impacts of climate change.

Unseen crisis: Threatened gut microbiome also offers hope for world
- Plants and animals provide a home within themselves to an invisible community of microbes known as the microbiome. But these natural microbial communities are being degraded and altered by human-caused biodiversity loss, pollution, land-use change and climate change.
- On the macro level, habitat loss and diminished environmental microbe diversity, particularly in urban environments, is altering the gut microbiomes of humans and wild animals. Studies have linked microbiome changes to higher risk of chronic and autoimmune diseases.
- Coral bleaching is an extreme example of climate stress-induced microbiome dysfunction: During heat waves, beneficial microbes go rogue and must be expelled, leaving the coral vulnerable to starvation. Microbiome resilience is key to determining corals’ ability to acclimate to changing ocean conditions.
- There are solutions to these problems: Inoculating coral with beneficial microbes can reduce bleaching, while the restoring natural green spaces, especially in socioeconomically deprived urban areas, could encourage “microbiome rewilding” and improve human and natural community health.

History on the walls: Graffiti brings Manaus’s Indigenous roots to light
- Graffiti artists are painting murals recounting the history of Indigenous people and honoring their culture in the capital of Amazonas, the Brazilian state with the largest Indigenous population.
- Indigenous community leaders say they hope the movement will increase the visibility of Indigenous people living in cities, who often face poverty, housing insecurity and stigma that discourages many from maintaining their culture and identity.
- Fearing cultural erasure, Indigenous activists are urging Indigenous people to embrace their ancestry and identify themselves as Indigenous in Brazil’s next census, expected to begin in August 2022.
- As Indigenous people in cities reclaim their identities, occupying public spaces through street art is playing a key role in the fight to make Indigenous people in urban areas more visible.

Big Apple birding is set to take flight: Here’s how to get started this Spring
- New York City is home to some of the most competitive bird watchers in the world, says avid birder Rochelle Thomas.
- Perhaps unrivaled in their intensity, NYC bird watchers have become driven by what we would otherwise perceive to be a leisure activity.
- In an interview with Mongabay, Thomas shares her tips on where and when to get in on the action starting in mid April.

Threatened wetlands in Paraguay’s Lake Ypacaraí raise legal questions
- Wetlands surrounding the protected Lake Ypacaraí in Paraguay are being filled in to allow for the construction of housing and tourism projects.
- In addition to providing habitats for countless species of flora and fauna, the wetlands act as a filter for freshwater and help control flooding and erosion.
- The projects were approved by the Ministry of Environment, sparking outcry from congressmen who want to know if protected area laws are being ignored in favor of urban development.

In Nepal, a messy breakup with hybrid seeds is good news for organic farming
- Some farmers in Nepal are slowly returning to organic farming methods using native crop varieties, after more than a decade of hybrid seeds being available in the market.
- Critics say hybrids require more intensive use of chemical fertilizers and pesticides, and produce fruit and vegetables with less flavor than native or openly pollinated varieties.
- The government is also supporting the push for organic, including through subsidies for farmers, but acknowledges it’s difficult to change minds.
- Many farmers continue to prefer hybrids, despite the associated problems, because of their higher yields, which mean more income.

In Kathmandu, a struggle for water amid worsening floods
- In Kathmandu, residents face the dual challenges of freshwater aquifers running dry, and increasingly unpredictable monsoons causing flash floods.
- The combination of climate change and a rapidly growing urban population is straining an already overwhelmed municipal water system, forcing many residents to have to buy water by the tank at high prices.
- An ambitious project to pipe water to the city from a nearby river was shut down within months of its long-delayed start — a victim of the monsoon floods that destroyed a dam and water treatment plant.
- Another solution being explored is rainwater harvesting, which proponents say should be complemented by restoration of Kathmandu’s green areas and restrictions on drawing groundwater.

More trees means healthier bees, new study on air pollution shows
- Scientists analyzed levels of chemical pollutants in native jataí bees across eight landscapes in Brazil’s São Paulo state.
- They found that in landscapes with more vegetation, the bees had fewer pollutants, at lower levels, indicating that the plants act as a filter and protective barrier
- The findings add to the growing scientific evidence about the importance of afforestation in urban areas, including creating ecological corridors to connect separate landscapes.
- Air pollution is the world’s top driver of illness and death from chronic noncommunicable diseases.

Insects and other invertebrates on tropical islands face challenges as development and tourism expand
- Oceanic islands host 50 percent of the world’s endangered species, but human activities can greatly disturb these isolated ecosystems.
- The number and diversity of insects and other invertebrate species decrease on islands dedicated to urban development or tourism, according to a new study in the Maldives.
- Fragmented habitats take a toll on these species on urban islands, while pesticides are the suspected culprits on tourist islands.

In Indonesia’s ‘Dragon Village,’ customs and nature are at the center of life
- The village of Kampung Naga in Indonesia’s West Java province has for decades eschewed modernization for a way of life rooted in a deep spiritual connection to nature.
- Kampung Naga families have worked for generations to preserve the forest in the Ciwulan River Basin, all under the guidance of a customary rule book.
- They have also worked to reintroduce more than 10 variants of rice seeds that were phased out during the 1950s in favor of new higher-yield varieties.
- Today, Kampung Naga offers a limited form of tourism, aimed at presenting the community’s customary traditions to a handful of curious outsiders at a time.

Honey bees find food more easily in cities, thanks to abundant urban gardens
- In London, western honey bees travel shorter distances to find their meals in metropolitan areas than in agricultural ones.
- A rich supply of gardens and decorative flowers provides ample nectar close to urban hives.
- Adding native flowers and similar foraging hotspots near open fields would help support bees in intensively farmed areas.

In Indonesia, a coastal town rejects ‘metropolitan’ model for mangroves
- Sofifi, the tiny capital of one of Indonesia’s remotest provinces, has made mangrove conservation and ecotourism a central part of its development.
- The town recently inaugurated the Guraping Mangrove Tourism Forest, which officials hope will draw tourists to the town and help it develop into something greater than an administrative hub.
- Indonesia is home to nearly a quarter of the world’s mangrove forests, an important ecosystem that sequesters carbon, blunt the impact of storm surges, and harbour a rich array of marine life.

Borneo’s bearded pigs and traditional hunters adapted to oil palms. Then came swine fever
- Oil palm expansion and urbanization have altered the traditional hunting of bearded pigs by the Indigenous Kadazandusun-Murut (KDM) community in Sabah, Malaysia, a new study has found.
- Researchers interviewed 38 hunters on changes in pig behavior and hunting practices before the African swine fever (ASF) epidemic hit Sabah in 2021.
- They found that even though pig hunting patterns have changed dramatically, the activity remains a cornerstone of KDM communal culture for food, sport, gift-giving, festivals and celebrations.
- As ASF devastates wild pig populations, the researchers’ findings highlight a need for long-term hunting management that conserves both the bearded pig and Indigenous cultural traditions.

Studies debunk ‘nature is healing’ narrative from 2020 lockdowns
- Several new studies have tried to tally up the costs and benefits to the environment as a result of lockdowns around the world last year in response to the COVID-19 pandemic.
- One study showed that emissions of indirect greenhouse gases like CO and NO2 decreased significantly, but one of its authors says this likely won’t have much of an impact over the long term.
- Another study debunks the media hype behind the “animals are reclaiming the cities” trend last year, attributing the increased sightings to the fact that people forced to stay at home finally had time to start noticing the wildlife around them.
- In India, researchers concluded there were more negatives than positives for the environment, including a surge in the use of plastic packaging and PPE, as people shopped online and masked up.

As populations grow, how will thirsty cities survive their drier futures?
- The world’s rapidly expanding cities are on a collision course with climate change, presenting unprecedented challenges to municipal and national governments as they work to continue providing residents with access to safe and sufficient water.
- Increasingly, calls are made to rethink the way we develop urban watersheds and the way we live in them — with water sourcing, transport, use and reuse planning key to the process. One approach, water-sensitive urban design (WSUD) entails a complete reimagining of the role and use of water in urban areas.
- WSUD embraces the water cycle, and considers the entire watershed where cities are located. It uses green infrastructure such as permeable pavements, green roofs and rain gardens, to greatly reduce stormwater runoff. Conscious design allows water to be recycled and reused repeatedly for various purposes. Waste is greatly reduced.
- Some cities are already changing their development pathways to be more resilient to inevitable future climate extremes, with Singapore and Cape Town leading the way. Future water stress can be overcome, but work needs to start now before extreme weather events, including mega droughts and floods, hit.

Scientists, communities battle against Philippine land reclamation project
- A land reclamation project in the central Philippines spanning 174 hectares (430 acres) faces strong opposition from various organizations and civil society groups.
- The $456 million “smart city” project is a joint venture between Dumaguete City and E.M. Cuerpo, a local construction firm.
- While the project promises economic benefits, critics say these will be negated by its environmental impact, which includes covering 85% of Dumaguete City’s coastline and burying four marine protected areas.
- Critics also say the project has ignored the public consultation process, a requirement for a venture of this scale in the Philippines.

Black Death aside, we know surprisingly little about rodents and disease
- Rodents make up 40% of all mammal species on the planet, and an estimated 10.7% of them are known hosts of zoonotic diseases, such as cat scratch disease, bartonella, hantavirus, Lyme disease, leishmaniasis, leptospirosis, and the plague.
- A recent letter in the journal Conservation Biology calls for more attention and funding to be directed toward studying small rodents, “the wildlife species most likely to be abundant, come into contact with humans, and be potential reservoirs in future zoonotic outbreaks.”
- Controlling and mitigating the risk of zoonotic diseases through rodent control is another area that lacks research, with the current approach of killing and poisoning rodents in urban areas actually posing the risk of causing more disease.
- Experts call for evidence-based, whole-system approaches to control rodents and champion the One Health approach to address zoonotic disease, acknowledging that human, environmental, and animal health are all interconnected.

Lessons from Brazil’s São Paulo droughts (commentary)
- São Paulo is increasingly facing severe droughts, as is the case in 2021. In 2014 the city came close to having its reservoirs run dry. Brazil’s agriculture and hydropower also depend on reliable rains.
- Anthropogenic climate change is increasing the fluctuations in ocean surface water temperatures, and the frequency is increasing of the combination of warm water in the Atlantic and cold water in the Pacific off the coasts of South America, a combination that leads to droughts in São Paulo.
- The trends in ocean temperatures are expected to worsen these droughts, but what could make them truly catastrophic is the prospect of this variation being combined with the impact of deforestation depriving São Paulo of the water that is recycled by the Amazon forest and transported to southeastern Brazil by the “flying rivers.” The lessons are clear: control global warming and stop deforestation.

As humans close in on their habitat, crocodiles in the Philippines snap back
- In mangrove-rich Palawan, residents are advised to steer clear of crocodile habitats as the hatching season makes the reptiles more aggressive.
- There are two crocodile species in the Philippines: the endemic Philippine crocodile and the bigger and more aggressive saltwater crocodile, found throughout Asia and the Pacific.
- Crocodile attacks on humans have increased in recent years, which experts attribute to the encroachment of houses within crocodile habitats, particularly mangrove swamps.
- To minimize the risk to lives, both human and crocodile, NGOs say Palawan should implement its crocodile conservation program, which includes, among other things, relocating residents away from crocodile habitats.

‘I am Indigenous, not pardo’: Push for self-declaration in Brazil’s census
- Brazil’s 2010 census was the first to map out the presence of Indigenous people throughout the whole country, but still maintained the term pardo, for a mixed-race individual, that Indigenous activists say has long been used to render Indigenous identities “invisible.”
- The next census is due in 2022, and activists and leaders are mounting a campaign to get all Indigenous Brazilians to self-declare as Indigenous.
- Getting a more accurate picture of the number and distribution of Indigenous people, especially in urban areas, is key to informing public policies geared toward their specific needs, experts say.
- “Everything is Indigenous,” says Júlio César Pereira de Freitas Güató, one of the Indigenous leaders promoting the campaign. “All the rest is invasion.”

In Rio de Janeiro, Indigenous people fight to undo centuries of erasure
- Rio de Janeiro holds a special place in Brazil’s history, but many of its residents are unaware of the city’s Indigenous heritage — from the names of iconic places like Ipanema and Maracanã, to the Indigenous slave labor that built some of its most recognizable structures.
- Nearly 7,000 Indigenous people live in Rio, the fourth-biggest population among Brazilian cities; a unique interactive map by Mongabay shows how they’re spread across the city, as well as their living conditions and ethnic groups.
- Despite their presence, and Rio’s famed diversity and laidback culture, Indigenous people in the city continue to face prejudice and a “silencing” of their traditions and culture that they attribute to centuries of efforts to erase them and make them invisible.
- But Indigenous people are pushing back, agitating to get their rights on the political agenda, and working through academia to unearth the Indigenous history of the city that has long been hidden.

In Boa Vista, Indigenous Brazilians retake their identity through education
- The city of Boa Vista near Brazil’s borders with Venezuela and Guyana is home to Indigenous groups whose ancestral range don’t recognize national boundaries, and who still continue to flow into Brazil from crisis-stricken Venezuela.
- The colonization of Boa Vista by Europeans forced the Indigenous inhabitants off their lands on the banks of the Rio Branco, and resentments simmer today over the return of some of those lands to the original owners.
- The land conflicts also killed off the use of the many ethnic languages spoken in the region, but community-led movements are seeking to bring them back, including in learning materials published by the local university.
- Higher education is seen as a life-changing opportunity for Indigenous students, not just for their personal growth but also for the avenues it opens up to advocate for and empower the wider Indigenous community.

A startup deploys black soldier flies in the Philippines’ war on waste
- In Davao City, in the southern Philippines, a startup has introduced the use of black soldier flies (Hermetia illucens) to address kitchen waste.
- The flies are fed kitchen waste, turning the food waste into compost, while their larvae, rich in protein, is touted as alternative feed for livestock.
- Proponents say insect protein is a much better alternative than commercial livestock feed made with fishmeal, associated with depleting fish populations, or soybeans, linked to deforestation and extensive use of pesticides and fertilizers.
- Treating kitchen waste with black soldier flies is also being touted as a cleaner alternative to municipal plans to incinerate the waste to generate electricity, which would contribute to air pollution.

In Brazil’s most Indigenous city, prejudice and diversity go hand in hand
- São Gabriel da Cachoeira, in northern Amazonas state, is recognized as Brazil’s most Indigenous municipality: an estimated 90% of its population is Indigenous, accounting for both its urban and rural areas; the urban area alone is 58% self-declared Indigenous.
- Spread across an area the size of Cuba, São Gabriel da Cachoeira has a history marked by the arrival of Brazilian military forces in 1760 and subsequently Catholic and Protestant missionaries, organized Indigenous social movements, as well as national and international NGOs focused on defending the environment and the Indigenous peoples.
- According to the census, there are 32 indigenous ethnic groups in São Gabriel da Cachoeira, many of them unknown in the rest of the country, such as the Koripako, Baniwa, Baré, Wanano, Piratapuya, Tukano, and Dãw people.
- The municipality is the only one in the country with four official languages, in addition to Portuguese: Baniwa, Tukano, Nheengatu and Yanomami. But despite its cultural and ethnic diversity, there are frequent reports of discrimination against Indigenous people.

Humanity’s challenge of the century: Conserving Earth’s freshwater systems
- Many dryland cities like Los Angeles, Cairo and Tehran have already outstripped natural water recharge, but are expected to continue growing, resulting in a deepening arid urban water crisis.
- According to NASA’s GRACE mission, 19 key freshwater basins, including several in the U.S., are being unsustainably depleted, with some near collapse; much of the water is used indiscriminately by industrial agribusiness.
- Many desert cities, including Tripoli, Phoenix and Los Angeles, are sustained by water brought from other basins by hydro megaprojects that are aging and susceptible to collapse, while the desalination plants that water Persian Gulf cities come at a high economic cost with serious salt pollution.
- Experts say that thinking about the problem as one of supply disguises the real issue, given that what’s really missing to heading off a global freshwater crisis is the organization, capital, governance and political will to address the problems that come with regulating use of a renewable, but finite, resource.

Ecuadoran water fund transforms consumers into conservationists
- The Regional Water Fund of Southern Ecuador (FORAGUA) operates in 14 municipalities, serving 500,000 residents, and has restored 1,500 hectares (3,700 acres) of land and put an additional 337,000 hectares (833,000 acres) under conservation.
- By 2030, the fund aims to work in 39 municipalities, serving 1 million people and conserving 600,000 hectares (1.48 million acres) of land.
- A pilot project to incentivize landowners to rewild their properties and take up alternative livelihoods shows that where landowners could earn 50 times more per hectare cultivating guanabana, a local fruit, than raising cattle.
- Municipal residents pay on average $1 per month to FORAGUA for their water consumption, with 90% of funds raised going to conservation projects.

The perils of relying on high-tech networks in a warmer world (commentary)
- Wild snowstorms paralyzed electricity infrastructure in Texas, a state in the country with the world’s largest economy.
- Just imagine what climate change fueled extreme weather will do to our cities as infrastructure and ICT systems become increasingly interconnected.
- Many see high-tech “smart cities” as a climate solution, but just how smart are they?
- This article is a commentary and the views expressed are those of the author, not necessarily Mongabay.

Researchers urge better protection as wetlands continue to vanish
- Wetlands provide many benefits to ecological and human communities alike, from nutrients and nurseries to flood control and climate change mitigation.
- However, as much as 87% of the world’s wetlands has been lost over the past 300 years, with much of this loss happening after 1900.
- In response, nations banded together and in 1971 ratified the Ramsar Convention on Wetlands, an intergovernmental treaty designed to facilitate wetland conservation and sustainable use around the world.
- But 50 years on, researchers say the convention has not led to effective protection and wetlands continue to blink out.

Whale shark stranding points to silting of Indonesia’s Kendari Bay
- Volunteers and officials successfully pushed a whale shark back out to sea after it got stranded in shallow water in Indonesia’s Kendari Bay.
- The incident, which one rescuer said was a first, has highlighted the consequences of the rapid silting of the bay amid a spate of development projects in the area.
- The clearing of land allows dirt to run into waterways, with the accumulated sediment halving the depth of Kendari Bay and making flood prevention more difficult.
- Amid the silting, fishing catches have declined and there are indications of heavy-metal contamination of the water.

How to turn climate ambitions into reality: Q&A with Nigel Topping
- 2020 was supposed to be a landmark year for taking stock on climate and biodiversity commitments and determining how societies move forward to address the world’s most pressing problems. Instead, the COVID-19 pandemic intervened, leading to the postponement or cancellation of many events, including the 26th United Nations climate conference (COP26).
- But while COP26’s delay may have stalled government to government negotiations at national levels, it didn’t prevent the parties from advancing efforts to address climate change, including the push to connect government targets with initiatives by sub-national governments, cities, companies, and civil society groups.
- To lead on this latter front, Gonzalo Munoz and Nigel Topping were appointed as High Level Climate Action Champions for the upcoming conference: “Our role is quite literally to champion the ambition and actions taken by non-state actors in addressing climate change. This means that Gonzalo and I work with partners across the world – cities, states and regions, businesses, investors, and civil society groups – to raise the awareness of, ambition for, and levels of action being taken to address climate change.”
- Topping spoke about these issues and more during a January 2021 conversation with Mongabay Founder Rhett A. Butler.

The promise of ‘bird-friendly’ cities: Q&A with author Timothy Beatley
- University of Virginia professor Timothy Beatley lays out a case for building cities that are better hosts to birds and the broader natural world in The Bird Friendly City: Creating Safe Urban Habitats.
- His case rests on the benefits that birds provide, and he discusses the need for equal access to nature for all city-dwelling communities.
- From small home improvements to skyscrapers covered in greenery, Beatley covers the adaptations necessary for more “natureful” cities around the world.

Singapore embarks on a million-tree planting spree to protect its future
- Between 1953 and 2018, Singapore lost nearly 90% of its mangroves to urban expansion and other human activities.
- Singapore has launched a new nature park that covers 400 hectares (990 acres), in an area that serves as a refueling site for migratory birds and a home to oriental hornbills, otters and crocodiles.
- The initiative is part of a larger effort to plant 1 million trees across the city-state by 2030.
- In addition to adding wildlife habitat, researchers say reforestation will help sequester carbon, lower the temperature of the city, and provide buffers against erosion and a rising sea.

Missing mangroves are root of contention over Philippine airport project
- Work on a new international airport project in Bulacan, just north of Manila, has already resulted in the decimation of more than 600 mangrove trees in the Manila Bay area, residents say.
- Bulacan’s coast is a key mangrove forest and important bird and biodiversity area, and one of several sites along the bay that’s facing threats due to land reclamation projects.
- The Bulacan “aerotropolis,” a 2,500-hectare (6,200-acre) airport complex, is part of President Rodrigo Duterte’s revised “Build, Build, Build” infrastructure program and has been awarded to San Miguel Corporation, the Philippines’ biggest company by revenue.
- The cutting of mangroves is prohibited under Philippine law, but no one has been held accountable for the hundreds of trees cut in Bulacan — a problem that residents and environmental groups say will intensify as construction of the airport returns to full force by October.

Discovery of threatened species drives bid to protect Vietnam forest
- The impoverished district faces the same threats as many of Vietnam’s natural areas, including poaching, deforestation and urban development.
- FFI and GreenViet, the conservation NGOs that carried out the survey, are working to convince government officials to establish a nature reserve or national park in Kon Plong.
- More than 120 species of mammals and birds were recorded in Kon Plong, including the critically endangered gray-shanked douc langur, a monkey endemic to Vietnam, as well as the northern yellow-cheeked gibbon, Owston’s palm civet, pygmy slow loris — all endangered species — plus Asiatic black bear, otters, and forest cats.

Finding nature in cities
- Today we’re exploring nature in cities with author Kelly Brenner and urban forester Georgia Silvera Seamans.
- To help us dive into urban ecology, we speak with Kelly Brenner, a naturalist and writer whose most recent book is called Nature Obscura: A City’s Hidden Natural World. Brenner, who lives in Seattle, Washington, joins us today to discuss some of the wildlife encounters she details in the book and to provide some tips on how anyone can go about exploring nature in the city they live in.
- We also welcome to the program Georgia Silvera Seamans, an urban forester who has spearheaded a number of “hyper local urban ecology” projects in New York City. Silvera Seamans is here to tell us about the Washington Square Park Eco Projects, which include monitoring, educational, and advocacy efforts in the iconic NYC park, and to tell us how urban ecosystems benefit all city-dwellers.

As lockdown ends, Manila’s dirty air is back. It doesn’t have to stay
- It’s still possible to maintain improved air quality even as lockdown eases in Metro Manila, a newly released report says.
- The air quality in the Philippine capital region improved after the start of the lockdown on March 15, but began deteriorating in May, when authorities started easing the measures.
- The report recommends adapting many of the measures implemented during the lockdown, including maintaining limited work arrangements and coming up with “people-centric” urban planning designs.
- Local governments should shift to technologies that depend less on fossil fuels and encourage this transition by providing incentives to both private citizens and companies, the report suggests.

Nature needs cities, and cities need nature (commentary)
- At a time when the world is losing its biodiversity at an alarming rate, and that loss has been linked to disease outbreaks, urban nature is more important than ever. Yet urbanization is a major cause of habitat loss – which drives much of the staggering loss of biodiversity
- With thoughtful planning, cities can connect habitats within and outside of city limits in ways that help protect populations of animals and plants that would otherwise be fragmented and vulnerable to extinction.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.

Insects decline on land, fare better in water, study finds
- A meta-analysis has found that land-dwelling insect populations are decreasing by about 0.92% per year, which amounts to 50% fewer insects in 75 years.
- The numbers of insects that live in the water are on the rise by about 1.08% per year, a figure scientists attribute to effective water protection measures over the past 50 years.
- Habitat loss is associated with the decline of insects in this study.

A watery onslaught from sea, sky and land in the world’s fastest-sinking city
- The Indonesian capital has 300 days of rain a year and 13 rivers running through it, so it doesn’t lack freshwater; but rampant development has left much of its area paved over, preventing this water from replenishing the aquifers.
- Instead, the water it gets — from rain and from rivers — often leads to flooding because it can’t be absorbed into the ground and can’t run out to sea.
- City authorities and planning experts agree that the extraction of water from the aquifers must end, but to do so will require providing universal access to clean water.
- Efforts are underway to clean up waterways, educate the public to not dump waste in rivers, and build infiltration wells that will allow the earth to once again capture rainwater.

A vital mangrove forest hidden in Vietnam’s largest city could be at risk
- A majority of the flora in the area was killed by defoliants sprayed by the U.S. Air Force during the Vietnam War.
- Today, the replanted forest protects the city from storms, and stores huge amounts of carbon dioxide, though development plans and aquaculture pose threats to Can Gio’s continued health.

Indonesia’s new capital in the Bornean jungle on hold amid COVID-19 crisis
- Plans to kick off the construction of Indonesia’s new capital city in Borneo have been put on hold pending the country’s response to the COVID-19 pandemic, a top official says.
- The government had planned to begin building the infrastructure for the new city in the second half of this year, but has come under criticism for seeming to prioritize this project over its handling of the pandemic.
- Environmental experts who continue to oppose the project, citing its impact on the forests, people and wildlife of Borneo, have welcomed the news of its sidelining and say its funding should be reallocated to the COVID-19 fight.
- As of April 15, the Indonesian government has recorded 5,136 infections from the coronavirus and 469 deaths — the most of any Asian country outside China, where the outbreak began.

‘Intense’ human pressure is widespread among terrestrial vertebrates, study finds
- A new study assessing the cumulative impacts of human activities on wildlife found that the vast majority of terrestrial species are facing “intense” pressure due to humanity’s footprint across the globe.
- Researchers looked at human pressures across the ranges of 20,529 terrestrial vertebrates and found that 85 percent of the animals included in the study, or some 17,517 species, are exposed to “intense human pressures” in half of their range. About 16 percent, or 3,328 species, are exposed to these pressures throughout their entire range.
- The researchers say that their results could help improve assessments of species’ vulnerability to extinction.

Vervet monkeys thrive despite habitat loss in South Africa
- Vervet monkeys, native to Africa, have rapidly adapted to urban areas seeking food in peoples’ gardens and trash.
- Researchers in South Africa found that despite an abundance of food for vervets in such spaces, populations aren’t booming.
- By understanding vervet populations and behavior, researchers hope to minimize human-animal conflict in cities.

Water flowing up the mountain: Development devours forest reserve in Zambia
- A forest reserve outside Zambia’s capital, Lusaka, has shrunk to just 716 hectares (1,770 acres) from its original 1,750-hectare (4,320-acre) span to make way for housing and lifestyle developments.
- The developments are also pumping sewage into the Chalimbana River, contaminating the fish and water that local communities rely on, and leading to outbreaks of diarrhea.
- Top government officials have been named among the recipients of some of the plots, including the vice president, chief justice, and ministers.
- Activists mounting a legal challenge to end the construction and restore the forest to its previous state saw an earlier ruling in their favor overturned, and are skeptical about getting justice in what they call “an engineered case.”

How cities can lead the fight against climate change using urban forestry and trees (commentary)
- Comprehensive urban forestry planning can influence the everyday lives of citydwellers by reducing storm water runoff, decreasing wildfire risk and severity, reducing urban heat islands, decreasing utility costs, increasing economic growth, and providing clean drinking water.
- Urban trees also have the ability to sequester atmospheric carbon dioxide (CO2) and serve as long-term carbon sinks. However, cities seem to be lacking in language and planning to link together various mitigation and adaptation strategies specifically to sequester and store CO2 within urban trees.
- While there are examples of cities incorporating forest carbon storage and sequestration policies into their planning, these are limited, and often only in our largest cities. Many cities have excellent programming to encourage tree plantings and green space but are not quite comfortable taking a leap into climate mitigation claims and calculations. Here’s a look at what cities are doing.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.

Bali mangrove bay is now a conservation zone, nixing reclamation plan
- Indonesia’s maritime ministry has designated Bali’s Benoa Bay a conservation zone for religious and cultural activities, and traditional and sustainable fisheries.
- The decision effectively kills a $2 billion plan to reclaim land in the mangrove-rich bay for a tourism development featuring hotels, restaurants, entertainment venues and a convention center.
- While opponents of the development project have welcomed the decree, they say it’s only the first step toward ensuring that the bay receives full and permanent legal protection against such development plans.

New lease on life beckons for Arroceros, Manila’s hidden jungle
- Arroceros Forest Park in the heart of Manila is one of the few green spaces left in the bustling Philippines capital.
- Successive governments have tried to get rid of it for new developments, but the city’s newly elected mayor has announced plans to retain and rehabilitate it as part of his “green city” proposal.
- The park is home to more than 3,000 trees, including 60 native species, and serves as a rest stop for migratory birds.
- Often dubbed the “lung” of Manila, Arroceros has been shown to mitigate the city’s notorious air pollution, and plays a key role in minimizing flooding, another of the capital’s litany of problems.

Decolonizing trees in a tropical city to nurture multi-cultural identity
- The survey found that 73 percent of trees in Georgetown were cultivated for their edible fruits.
- The random distribution of trees suggests social cohesion, fostered by a sharing of food traditions, and could provide a blueprint for other multicultural cities.
- But climate change and economic growth mean tree preservation and planting are needed to mitigate social and environmental impacts.

For Indonesia’s Kendari Bay, silting is a death sentence
- Researchers say the Kendari Bay, on the island of Sulawesi, is rapidly disappearing.
- The main culprit is land clearing for development projects around the bay and the rivers the feed it. The land clearing releases sediment into the water that eventually settles on the bottom of the bay.
- The bay may be decades from filling up completely, but studies suggest hope of saving its plant and animal life may already be lost.

Indonesia picks coal and oil heartland as site of new capital city
- President Joko Widodo announced on Aug. 26 that the new capital would sit on the border area between the districts of North Penajam Pasar and Kutai Kartanegara, in Borneo’s East Kalimantan province.
- Among the reasons for choosing that location are the low risk of natural disasters such as earthquakes and tsunamis, and the availability of government-owned land spanning the size of London.
- Construction is expected to begin as early as 2021, with a completion date of 2024, when Widodo’s second and last term in office ends, the planning minister says.
- Environmental and indigenous rights activists are wary about the mega project’s impact on the region and the prospect of land grabs by speculators looking to cash in on the relocation of the capital.

Environmental justice and urban rat infestations
- Today we speak with Dawn Biehler, an associate professor at the University of Maryland, Baltimore County, whose research focuses on the history and public health impacts of rats and other pest species in Baltimore.
- The issue of urban pests like rats in Baltimore has been in the news lately due to tweets sent by US President Donald Trump about the city being “rat and rodent infested.” Trump isn’t the first American politician to use this kind of rhetoric to target communities that are predominantly made up of people of color, while ignoring the fact that policies deliberately designed to marginalize communities of color are at the root of the pest problems in many cities.
- Biehler, who is also the author of the 2013 book Pests in the City: Flies, Bedbugs, Cockroaches, and Rats, joins us on this episode of the Mongabay Newscast to discuss how rat infestations in cities are actually an environmental justice issue and how they can be dealt with in an environmentally sustainable manner.

Red flags as Indonesia eyes relocating its capital city to Borneo
- The Indonesian government will build a new capital city on the island of Borneo within the next five years, and without clearing any protected forest, the planning minister says.
- The exact location for the so-called forest city hasn’t been announced yet, but the plan has already raised fears about the impact to the environment and to local communities who are dependent on the region’s dwindling forests.
- Mining, logging, and oil palm cultivation have already taken a heavy toll on Borneo’s rainforests and wildlife, including critically endangered orangutans.
- The influx of migrants from other parts of Indonesia has historically been a flash point, sparking sometimes deadly conflicts with indigenous communities, and activists fear an escalation in both conflicts and land grabs as more people move to the new capital.

West Nile virus lingers longer in birds exposed to light pollution
- House sparrows exposed to light at night had higher levels of West Nile virus in their blood for two days longer than sparrows that were exposed to darkness, according to a new study.
- The research sought to mimic the effects of light pollution common to urban environments on virus levels in a known reservoir of West Nile virus, which can cause a flu-like fever in humans.
- The team’s research suggests that an outbreak could be 41 percent more likely to happen as a result of the persistence of the virus in this host.

Indonesian governor latest official busted for bribes in environmental case
- Three local officials, including a governor, have been arrested and charged for allegedly taking bribes in a land reclamation project.
- The businessman behind the project in Sumatra’s Riau Islands, who has also been arrested, planned to build a resort and tourism site on reclaimed land in a bay designated as protected.
- Observers say that projects involving land reclamation activities are prone to corruption.

As opposition wanes, a Malaysian land reclamation project pushes ahead
- When Mahathir Mohamad was elected Malaysia’s prime minister in May 2018, Chinese-backed developments were put in the political crosshairs.
- Forest City, a massive mixed-use development being built off the southern coast of Peninsular Malaysia, had already attracted controversy due to concerns about its impact on fisheries, seagrass beds, mangroves, and relations with neighboring Singapore.
- Although it’s been a bumpy political year for Forest City’s developers, construction continues on the project, as does debate over its environmental impacts.

No environmental permit for Bali bay reclamation plan amid opposition
- The Indonesian government says it won’t issue a key permit for a plan to build artificial islands in Bali’s Benoa Bay as long as locals remain strongly opposed to the project.
- The plan is to build artificial islands for a multibillion-dollar complex featuring hotels, restaurants, entertainment venues and a convention center.
- The project appeared to die last August when another permit, the location permit, expired without the government renewing it. The fisheries ministry later issued a new location permit.
- With the developer now seeking to obtain an environmental permit, local communities are gearing up for another fight against a project they say could damage the mangrove-rich area on which their livelihoods depend.

As Cambodia swelters, climate-change suspicion falls on deforestation
- Cambodia has one of the highest rates of deforestation in the world, with key drivers including demand for timber products, land-use conversion, and urbanization.
- Extreme temperatures have led to public criticism linking deforestation to unusually hot weather.
- The Cambodian government has denied this connection, but emerging science provides compelling links between the two issues.

Laurel Chor on photojournalism and Hong Kong’s ‘incredible biodiversity’
- Hong Kong is a city of 7.3 million people and isn’t known for its biodiversity, but journalist Laurel Chor has made it her mission to educate people about their natural heritage
- A photojournalist and filmmaker, she has traveled the world covering stories with images and words, from Iceland to the DRC.
- In conjunction with Ecosperity Week and World Environment Day, Laurel will be speaking at a special edition of Ecosperity Conversations on June 7. She is also a judge for the photo competition Shoot for Sustainability.

As Indonesia mulls moving the capital, indigenous groups fear another land grab
- Indigenous rights advocates worry the president’s plan to relocate Indonesia’s capital to the island of Borneo could result in seizure of lands belonging to local communities.
- The Indigenous Peoples Alliance for the Archipelago, an NGO, is currently working to determine if any indigenous communities would be affected by the plan, though it is difficult to determine until the government’s plans come into sharper focus.
- As potential sites for the new capital, President Joko Widodo has floated Palangkaraya, Gunung Mas and Katingan in Central Kalimantan, and Bukit Suharto in East Kalimantan.

In traffic-blighted Penang, transport upgrade plans raise hopes and fears
- The government of Penang, Malaysia, has big plans to upgrade the state’s transport system via a new network of highways, bridges, tunnels and rail lines.
- While many are hopeful the new roads will ease the island’s infamous traffic, conservationists are concerned that the plan will lock Penang into a car-oriented future.
- One highway project has already been hit by a deadly landslide, adding to residents’ concerns.

Cities may save some species from extinction, but they don’t save species’ ecological functions
- Some species are not only able to adapt to life in urban areas but actually thrive and grow more abundant than they might have in their natural surroundings.
- Thus some cities have been declared urban conservation hotspots — but research published last year shows that while those cities might help preserve robust populations of otherwise threatened species, they do not help preserve the crucial ecological functions of those species.
- If species and the ecological functions they provide are allowed to disappear altogether from natural habitats and only continue to persist in urban areas, that could have “long-term, unexpected effects on ecosystems,” researchers say.

The view from the bottleneck: Is nature poised for a big comeback?
- A new theory, from bottleneck to breakthrough, posits that urbanization, falling fertility and the end of extreme poverty could result in a much greener world than the one we inherited.
- The scientists behind the idea believe that conservation must continue to “hold on” to species and places as nations make their way through the tightening bottleneck.
- If trends today persist, the global population could urbanize and fall dramatically in the next couple of centuries, turning conservation into restoration.
- This post is part of “Saving Life on Earth: Words on the Wild,” a monthly column by Jeremy Hance, one of Mongabay’s original staff writers.

Urbanization in Asia provides a window of hope for tigers, study finds
- The transition to cities by Asia’s human population is likely to affect the continent’s remaining tiger populations, according to a new study.
- Depending on policy decisions around migration, urbanization, education and economics, the trend toward urbanization could provide more space for tiger numbers to rebound.
- A team of researchers modeled five different “socioeconomic pathways” for the continent, showing that a focus on sustainable living could result in fewer than 40 million people living within the tiger’s range by the end of the century.
- But that number could also balloon to more than 106 million people if countries veer away from international cooperation and poor management of urbanization.

Cities could help conserve pollinator communities
- While cities are generally considered to be poorer in biodiversity than rural areas, new research finds that urban areas could actually play a key role in conserving pollinator communities.
- A team of researchers led by scientists at the UK’s University of Bristol studied pollinators and floral resources at 360 sites in four British cities representing all major urban land uses, including allotments (community gardens), cemeteries, gardens, man-made surfaces like parking lots, nature reserves and other green spaces, parks, sidewalks, and road verges.
- After sampling 4,996 insects and documenting 347 flower-visiting pollinator species interacting with 326 plant species, the researchers found that gardens and allotments provide especially good habitat for pollinators, and that lavender, borage, dandelions, thistles, brambles, and buttercups are important plant species for pollinator communities in cities.

Rhinos or roads? Nepal deals with a tricky balancing act
- Nepal’s Chitwan National Park, a UNESCO World Heritage Site, is home to the world’s second largest population of greater one-horned rhinos, as well as nearly 100 Bengal tigers and more than 54 other mammal species.
- After a 2016 mission, UNESCO warned that Chitwan could be placed on the World Heritage in Danger list if a number of planned infrastructure projects were completed as proposed.
- Since then, the largest projects have been suspended or rerouted; now, conservationists say they are more concerned by the impacts of unplanned urbanization and local flood-control projects.
- Local officials often struggle to balance protecting Chitwan’s ecosystem against the popular demand for infrastructure development projects.

A development project in a Bali mangrove bay gets a new lease on life
- A controversial plan to reclaim land in Bali’s Benoa Bay for a commercial and entertainment development project was thought to have ended in August when its permit expired.
- In late November, Indonesia’s maritime ministry issued the developer a new permit that effectively revives the plan.
- Reclamation can only proceed, however, if the developer can obtain approval for its environmental impact assessment from the environment ministry. Its failure to do so earlier this year was what led to its initial permit expiring.
- Activists say they will continue to oppose the project, which they fear will destroy the mangrove-rich ecosystem and harm the livelihoods of thousands of local fishermen.

For APEC’s poorest member, flashy cars point to another boondoggle
- Papua New Guinea will host the 2018 Asia-Pacific Economic Cooperation (APEC) Summit this week.
- The PNG government says the summit will catalyze economic growth and development, but opposition leaders have criticized what they say is extravagant spending even as infrastructure and public services remain severely underfunded.
- The experience of the 2015 Pacific Games, the last time PNG hosted a major international event, could hint at the long-term legacy the APEC summit will leave behind.

Evicted for a showpiece project, this PNG community fights for justice
- Papua New Guinea has embarked on a surge of building projects in Port Moresby as the capital city prepares to host the Asia-Pacific Economic Cooperation (APEC) summit.
- In the buildup to the summit, thousands of people were evicted from a settlement in Paga Hill, which is next to the conference hall where the APEC Leaders’ Summit will be held.
- Former residents of Paga Hill say their experiences of eviction, demolition and resettlement are a cautionary tale for others in the country who face relocation in the name of development.

Is northern India better prepared for air pollution this winter?
- Over the last few years, Delhi and adjoining regions in north India have consistently faced severe levels of air pollution during the winter season, from November to February. Overall air quality in Delhi this year has already dipped into the “poor” and “very poor” categories.
- Following criticism from courts and orders to devise comprehensive plans, India’s environment ministry and state governments, including those of Delhi and nearby regions, have formulated plans to tackle air pollution.
- They include satellite-based air pollution monitoring to check burning of crop residue in the winter, and strengthening of monitoring pollution from vehicles, among others.
- But some environmentalists feel that more needs to be done to curb the air pollution.

Jakarta cancels permits for controversial bay reclamation project
- The Jakarta administration has revoked permits to develop 13 of 17 artificial islands that are part of a $40 billion land reclamation project off the coast of the Indonesian capital.
- The project aimed to slow the high rate of land subsidence in Jakarta, but its critics, including the current governor, say it harms the environment and threatens the livelihoods of local fishing communities.
- An NGO leading the opposition to the project has called for permanent measures to halt the project, given that earlier suspensions to the same effect were eventually lifted.
- Four of the affected islands have already been completed; the city administration says it will put these to use in the public interest.

A civic outcry in Malaysia forces a Chinese builder to live up to its eco-friendly tag
- Forest City, a massive land reclamation project built by a Chinese developer and backed by the sultan of Johor state in Malaysia, was initially allowed to begin construction without a detailed environmental impact assessment.
- Facing public protests, and concern from neighboring Singapore, the government halted the project and required a laundry list of design changes to the city, which is projected to house 700,000 people upon completion.
- The project is marketed as an eco-friendly “future city,” but has been met with concern by environmentalists. China’s involvement has also caused political problems, including an announcement in August that Malaysia will not allow foreigners to purchase property in the development.
- This is the final installment in a six-part series on infrastructure development in Peninsular Malaysia.

As Bali reclamation project dies, activists seek conservation status
- Activists in Bali have welcomed the automatic cancellation of a permit for a reclamation project in the Indonesian resort island’s Benoa Bay.
- The permit expired after the developer failed to secure government approval for its environmental impact assessment for the project.
- The planned development would have cleared large areas of the bay’s mangrove ecosystem for new artificial islands to host a convention center, hotels, restaurants and entertainment venues.
- The activists have called on the government to restore the bay’s status as a strictly protected area for future conservation.

Amid corruption scandal, Malaysia switches track on future of rail network
- Before he was voted out of office and slapped with criminal charges, former prime minister Najib Razak presided over a hugely ambitious rail expansion plan.
- Newly elected prime minister Mahathir Mohamad has suspended several key projects, citing cost overruns and concerns about China’s involvement.
- Public transit programs in the Kuala Lumpur region made significant gains under Najib, but revelations about the nexus of infrastructure projects and corruption leave the future of rail development in question.
- This is the fourth in a six-part series of articles on infrastructure projects in Peninsular Malaysia.

A river restored breathes new life into Kuala Lumpur
- Inspired by a global trend of urban river restorations, then-prime minister Najib Razak in 2012 launched a megaproject to clean up the Kuala Lumpur’s rivers and beautify riverfront areas.
- Ridiculed at first, the River of Life project has made notable strides towards its goals, and officials say it is on track to be completed on time and below budget.
- The initiative is part of a complex legacy left by Najib, who was swept out of power amid a corruption scandal and is currently awaiting trial for breach of trust and abuse of power.
- This is the third article in a six-part series about infrastructure projects in Peninsular Malaysia.

Indigenous stewardship is critical to success of protected areas (commentary)
- A recent article in Science reports that, while the portion of the world’s terrestrial surface allocated to protected areas has grown to around one-sixth of the area available, a significant number of these areas are so compromised by human pressures that they may be unable to meet their conservation goals.
- What we increasingly understand is that if we are to address the threats posed by activities ranging from logging and mining to agriculture and urbanization effectively, we must seek out local solutions where possible. That means drawing on the knowledge of Indigenous Peoples and safeguarding their rights.
- In case after case, the world’s remaining strongholds of biodiversity remain intact thanks to the stewardship of the people living there. That is why conservation organizations have supported Indigenous Peoples and local communities as they negotiate with governments to win recognition of resource rights.

Cracks appear in Malaysia’s building spree, once a model for development
- Mongabay is launching a six-part series on infrastructure projects in peninsular Malaysia. The series will explore the magnitude and environmental consequences of massive infrastructure projects undertaken in the name of modernizing Malaysia.
- We discovered that while the concerns about the security of air, water and land are justified, this program produced unexpected economic gains, as well as considerable financial and political challenges.
- Surprise election results in May brought in a new government, placing into question the future of several planned projects.

Delhi residents protest against axing of the city’s green cover
- Residents of New Delhi, India’s capital, have come out in protest against the proposed felling of more than 16,000 trees for a project to build housing for government officials.
- Many of these trees are decades old, and residents say that planting trees elsewhere in the form of compensatory afforestation will not make up for the loss of green cover in the heart of the city.
- Delhi is among the world’s most polluted cities, and the national capital regularly recording toxic air pollution levels is what’s driving Delhi’s residents to protest the tree felling.

‘Urban Raptors’: Q&A with authors of book on ecology and conservation of city-dwelling birds of prey
- Nest cameras have been set up in cities across the United States to give viewers an intimate look into the nesting activities of urban-dwelling birds of prey like eagles, falcons, hawks, and owls. These raptors represent a rare instance of wildlife thriving amidst the hustle and bustle of areas densely populated by mankind.
- Raptor researchers Clint W. Boal and Cheryl Dykstra are co-authors of Urban Raptors: Ecology and Conservation of Birds of Prey in Cities, a new book that explores the science of how these birds of prey have adapted to city life and what humans can do to support them.
- Mongabay spoke with Boal and Dykstra about the urban raptor species discussed in the book, what kinds of unique threats the birds of prey face in cities, and how important these urban populations are to overall raptor conservation.

US urban areas are losing 36 million trees every year, study finds
- Forest Service researchers estimate that urban areas in the U.S. lost a collective total of 1 percent of their tree cover between 2009 and 2014. In total, around 175,000 acres of tree cover was lost annually.
- At the same time, they found “impervious surfaces” like asphalt roads and buildings increased at 1 percent per year.
- Trees provide a variety of benefits to cities from shielding buildings from the sun and reducing cooling costs and energy consumption, filtering pollutants from water and air, mitigating flooding and erosion, and helping in the fight against global warming by storing carbon. In total, analysts estimate urban trees save the U.S. around $18.3 billion every year. Impervious surfaces do not provide these benefits and often have the opposite effect.
- The researchers urge changes to management policy to prioritize tree cover and create more programs focused on protecting urban forests.

Cities need forests too: A call for forests amid our concrete jungles (commentary)
- More than half the world’s population lives in cities, and that’s set to rise to two-thirds – more than 6 billion people – by 2050. Yet we still depend on forests more than we think.
- Having wild places around is critical, not just for nature but also for people. A wealth of studies have shown that cities with plenty of trees feel like healthier, happier places than those without.
- While deforestation has many drivers, one underlying challenge is that society doesn’t value forests enough. That’s something we can – and need to – change as individuals and as a collective. It starts with spending time in forests, connecting with nature, and showing that we care.

Leopards could reduce rabies by controlling stray dog numbers in India, study finds
- Stray dogs make up about 40 percent of the diet of the roughly 40 leopards currently living in Mumbai’s Sanjay Gandhi National Park, according to a recent study.
- Dog bites lead to perhaps 20,000 deaths from rabies each year in India, according to the World Health Organization.
- A team of scientists figures that leopards kill 1,500 stray dogs each year, reducing the number of bites by about 1,000 per year and the number of rabies cases by 90.

Mexico City dwellers shoulder future of their urban ‘Water Forest’
- The territory, which conservationists and area residents are working to preserve, includes a large swath of southern Mexico City.
- The term “urban forest” typically describes public parkland or a collection of shade trees, but Mexico City’s Water Forest is an actual forest.
- The Water Forest also hosts endangered volcano rabbits (Romerolagus diazi) and Sierra Madre Sparrows (Xenospiza baileyi) as well as pumas, bobcats, white-tailed deer, and at least 10 percent of the bird species known in Mexico.

The uncertain future of Bogotá’s shantytowns
- Colombia’s massive population of internally displaced is second only to Syria, and thousands fleeing violence make homes in the forests outside of cities.
- Outside of Colombia’s capital of Bogotá, thousands live in groups of makeshift homes that form a range of communities from villages to shanytowns.
- The shanytowns present worsening health and public safety problems, and have a devastating impact on the forests where communities are established and growing.

Jakarta reclamation project allowed to resume, but opposition remains
- Indonesia’s central government has allowed work to resume on a project to build 17 artificial islands off the coast of Jakarta.
- The project, which proponents say will help address the city’s land subsidence and overcrowding problems, was suspended last year over environmental concerns and a corruption scandal.
- Opponents of the project include environmental activists, traditional fishermen and Jakarta’s newly inaugurated governor.

Trees provide ecosystem services worth $500 million to the world’s megacities
- Just as they do in forests and other natural ecosystems, trees deliver a variety of ecosystem services in cities. They sequester carbon and reduce air pollution and stormwater runoff, for instance.
- Researchers looked at 10 megacities on five continents that lie in five different biome types: Beijing, China; Buenos Aires, Argentina; Cairo, Egypt; Istanbul, Turkey; London, UK; Los Angeles, United States; Mexico City, Mexico; Moscow, Russia; Mumbai, India; and Tokyo, Japan.
- They determined that trees provide an average of $505 million in benefits to each megacity every year, or about $1.2 million per square kilometer of trees.

Urban heat island effect could more than double climate costs for cities
- The higher climate toll that cities will pay is due to the urban heat island effect, which is caused by the replacement of vegetation and bodies of water by concrete, asphalt, and other materials that trap more heat. The effect is only further exacerbated by the abundance of things like cars and air conditioners in urban areas, which emit more heat and global warming pollution.
- An international team of researchers with the UK’s University of Sussex, Universidad Nacional Autónoma de México, and Vrije University Amsterdam looked at 1,692 cities around the world in order to determine just how much the urban heat island effect could compound the losses already expected to result from global warming.
- The researchers found that, on average, economic losses from higher temperatures could be 2.6 times higher in cities than they would be if heat island effects weren’t factored into the equation.

Not out of the woods: Concerns remain with Nigerian superhighway
- The six-lane highway was shifted in April to the west so that it no longer cuts through the center of Cross River National Park, a ‘biological jewel’ that is home to 18 primate species.
- In a new study, scientists report that multiple alternative routes exist that would still provide the intended economic connections and avoid harming the environment in the area.
- However, Nigerian conservation and community rights group worry that the state government won’t follow through on its promises.
