Clouded leopard sighting raises questions about conservation and research in Bangladesh
- Clouded leopards occur in some South and Southeast Asian countries, but have fast been losing their habitat and, in 2021, IUCN declared the carnivore a vulnerable species.
- In Bangladesh, where there is no official record of the species, wildlife researchers studying other wildlife recently spotted clouded leopards in their camera trap footage, raising hope for their habitat conservation.
- Researchers have expressed concern about the lack of intensive research and conservation strategies for endangered species in Bangladesh.

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.

Overuse of antibiotics in Bangladesh aquaculture raises health concerns
- A recent study in Bangladesh reveals high rates of antibiotic resistance in pabda fish (Ompok pabda) bred by farmers through aquaculture.
- Consumption of antibiotic-resistant pabda fish may lead to the development of antibiotic resistance in humans as it exposes the food chain to multi-drug resistant (MDR) bacteria.
- Pabda aquaculture in Bangladesh produces around 20,000 metric tons annually, some of which is exported.
- Researchers are advocating educating farmers on the correct usage of antibiotics with the intervention of fisheries experts.

A Ramsar site in Bangladesh fast loses its fish diversity amid government inaction
- Tanguar Haor, Bangladesh’s second largest Ramsar site and one of the country’s most important habitats of breeding fish, has been losing its fish diversity.
- A recent study found that the number of available fish species is now below 100 while, just two decades ago, the figure was recorded to be 141.
- Experts blame anthropogenic factors, including overfishing and habitat destruction, as the causes of declining diversity.
- However, authorities are ignoring the rising urgency for conservation and are instead celebrating the “increased fish production in the wetland.”

Lesser noddy sighting stirs up birding community in Bangladesh
- In September, near Bangladesh’s Sonadia Island, an ornithologist and a birdwatcher recorded the sighting of lesser noddies, a seabird species never seen in Bangladesh before.
- Lesser noddies are tropical terns known to be confined to the Indian Ocean.
- Experts say it is unknown why lesser noddies traveled to Bangladesh, and predict that they will soon return to their original habitats after this temporary stopover.

Langurs in Bangladesh face extinction as hybridization between species escalates
- Bangladesh is home to less than 500 Phayre’s langurs and 600 capped langurs in the rainforests in the country’s northeast.
- A recent study has unveiled a trend of hybridization between Phayre’s langurs and capped langurs in Bangladesh, which are listed as critically endangered and endangered, respectively, by IUCN.
- Hybridization is a vital indicator of ecological change, and researchers are raising serious concerns about the genetic health of the two species and their future existence in the wild.
- The study holds human activities such as deforestation, habitat fragmentation and hunting as some of the causes responsible for increasing the risk of hybridization cases.

Tiger population census in Bangladesh shows a hopeful upward trend in the Sundarbans
- The latest tiger population census in Bangladesh, which was done by evaluating camera-trapping data, shows that the country is home to at least 125 adult Bengal tigers.
- The report shows almost a 10% increase since the last census in 2018 in the Sundarbans mangrove forests, which is considered to be Bangladesh’s only remaining habitat for tigers.
- Conservationists attribute this success to the efforts made in the region in recent years, including installing fences and increased patrolling against poaching.

New tourism restrictions to protect Bangladesh’s unique wetlands and coral-rich island
- Since 1999, Bangladesh has declared 13 biodiversity-rich areas as Ecologically Critical Areas (ECA) under the country’s environment protection act.
- However, the government has failed to conserve the ECAs over the years other than a few project-based protection measures undertaken in some of the areas like Saint Martin’s Island, Tanguar Haor, Hakaluki Haor, Cox’s Bazar Beach and Sonadia Island.
- Now, the current civil society-led government plans to limit tourism in biodiversity hotspots to ensure the health of the ecosystem.
- The coral-rich Saint Martin’s Island and one of the country’s largest wetlands, Tanguar Haor, will see the first through tourism restrictions.

Coastal farmers in Bangladesh give up shrimp farming for agriculture to combat salinity
- The decades-long shrimp aquaculture on Bangladesh’s southwest coast, which negatively impacts the environment in many ways, including creating a freshwater crisis, is now losing its importance as the farmers are gradually inclining toward agriculture again.
- Increased salinity, both due to sea-level rise and diversion of the upstream flow of freshwater, and peer pressure had forced the coastal farmers to venture into shrimp cultivation about four decades ago.
- For the last couple of years, excessive salinity and repeated viral outbreaks in shrimp farms have pushed the farmers back to agro-based farming again.
- Crop diversification plays a positive role in addressing the changes; however, water shortage poses a big challenge in restoring agriculture.

Bangladesh’s new government implements strong measures to eliminate single-use plastic
- Data shows Bangladesh generates around 87,000 tons of single-use plastics annually, of which 96% are directly discarded as garbage.
- Lack of awareness has led to the collection of plastic waste all over the cities, especially near rivers or lakes, where they mix with water and soil, affecting ecosystems and food chains.
- The current government in the country is implementing the existing law by banning single-use plastic, which started on Oct. 1.

Experts call for urgent leopard conservation efforts in Bangladesh
- The Indian leopard was once prevalent across most the forests in the Bangladesh landscape, but is now critically endangered in the country.
- The big cat’s population has rapidly declined in the country due to habitat fragmentation and degradation, prey crisis and wildlife trafficking.
- Experts suggest taking urgent conservation initiatives for the neglected species and bringing it into national conservation focus in Bangladesh.

Crop fields make way for profitable orchards in Bangladesh, imperiling food security
- The mid-western region of Bangladesh has long been characterized by dry weather due to low rainfall. However, over the last four decades, the agriculture thrived here due to a government-run irrigation project that relies on groundwater.
- A few years ago, following a significant increase in rice production, but a decrease in the groundwater level, the government started rationing irrigation to save groundwater.
- Consequently, the farmers began to opt for alternative non-water intensive crops and converted their arable lands into orchards, cultivating fruits like mangoes and lychees.
- Experts feared that although the transition may bring a secure cash crop for the farmers, this change in agriculture could hamper the country’s overall food security.

CITES suspends Bangladesh as illegal wild bird trade continues
- CITES, the international endangered wildlife trade convention, has suspended Bangladesh, one of its signatory countries, due to the illegal trade of birds, mainly import, for commercial purposes.
- Some common varieties of exotic birds traded within the country include endangered macaws and parakeets from Central and South America.
- Eighty-two private farms are registered in Bangladesh that can trade birds. Six of them are suspended for various reasons, including the violation of rules.
- The convention office recommends that the country establish adequate regulatory measures and act accordingly so that the trade of birds listed under CITES can be stopped.

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.

In the Sundarbans, women are embracing mangrove restoration as an alternative livelihood
- The vast Sundarbans mangrove forests along the southern coast of Bangladesh act as a shield and protect the coastal people and their livelihoods from tropical cyclones and tidal surges.
- In the last couple of years, the number of mangroves in the zone has increased as the government and some NGOs have introduced programs to plant mangrove trees on the coastal embankments as protection measures.
- Women from coastal villages, who know the ecosystem well, have been at the forefront of these reforestation projects and have also become entrepreneurial with mangrove forest resources.
- The involvement of local women and cooperative societies in mangrove restoration and conservation prompts a sense of ownership and agency among mangrove-dependent communities.

Bangladesh introduces awareness initiatives to curb panic over Russell’s vipers
- The Russell’s viper was thought to be nearly extinct in Bangladesh for many decades. Wildlife biologists were unaware of how widespread the Russell viper is in the country until 2013.
- The snake’s increase in population represents the grave danger that they are to people’s lives as many agricultural workers have been killed in the last few years due to the viper’s snakebites.
- The recent surge in snakebite incidents across the country, particularly during the Boro rice harvesting season from May to June, has led to a sudden rise in the indiscriminate killing of all snakes.
- In response to this crisis, the government has taken proactive steps to promote awareness about the importance of not harming snakes and to understand snake bites. Efforts include the dissemination of educational content on social media and mobile apps.

In the wake of Bangladesh’s deadliest dengue outbreak, researchers respond
- In 2023, Bangladesh experienced the deadliest outbreak of dengue fever in the country’s history.
- Climate change will likely make severe disease outbreaks more common.
- Common prevention strategies, like insecticides, are becoming less effective as mosquitoes gain resistance and the nature of disease changes.
- In response, researchers, nonprofits and Bangladeshi residents are searching for ways to protect their communities and families.

Scientists are racing to save South Asia’s butterflies from the threat of extinction
- Butterflies are some of Bangladesh’s most prolific pollinators and important ecosystem indicators.
- Insects, including butterflies, are especially vulnerable to climate change and other human-caused ecosystem changes.
- Despite the increasing threat of extinction, few legal protections or conservation initiatives focus on preserving butterflies and other insects.
- South Asian scientists are engaging communities in citizen science to garner attention to often-overlooked butterfly species.

Dhaka international symposium gathers at the intersection of art & climate crisis
- Climate change is affecting the work of performing artists as well as creative artists in South Asia.
- A July conference in Dhaka brought scholars and performers together to discuss the nascent studies of the intersection of climate change and culture.
- Artists are using their art to address the climate crisis. Some art forms are being lost because of climate impacts.
- The work of young art students shows how nature is infused in art from an early age.

Sundarbans fisherfolk are battered by cyclones amid fishing bans
- Fishers in the Bangladesh Sundarbans have been struggling with income due to damage caused to the mangroves by the recent tropical cyclone Remal and also the seasonal ban on resource hunting from June to August.
- In every disaster, poor fisherfolk are entangled more in a complex debt trap for moving on, and this year, the situation is more aggravating as the cyclone hit just before the fishing ban started.
- Nonetheless, the government is adamant on continuing the ban for the sake of forest resource conservation.
- At the same time, the government is still in the planning stage of providing people food support during the ban period, as has been provided to sea-bound fishers during the hilsa harvest ban period.

Bangladesh incinerator project sparks row between government & contractor
- A planned waste incineration project in Dhaka, which has sparked a debate between the government and the contracting company, has raised questions about potential pollution from the facility — and the overriding issue of what Bangladesh should do with its solid waste.
- Bangladesh’s daily per capita generation of solid waste is nearly 35,000 metric tons, with two city corporation areas of Dhaka producing more than 7,000 metric tons of waste per day, which could increase in the coming decades as the economy grows.
- In 1991, more than 43 hectares (106 acres) of landfill was required to dump the solid waste generated in the urban areas every year, while the landfill requirement in 2021 stood at nearly 223 hectares (550 acres), causing pressure on land-scarce Bangladesh.
- Nearly 80% of the solid waste in Bangladesh is organic in nature, and the hot, humid atmosphere is favorable for turning waste into a wealth of raw material for biogas and organic manure.

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.

Media must help reduce conflict between tigers and people in the Sundarbans (commentary)
- The Sundarbans is the world’s largest mangrove forest, supporting millions of people and myriad wildlife, including endangered tigers, which are increasingly killed for the wildlife trade or in retaliation for attacks on humans.
- Media outlets rarely focus on the root causes of this conflict – habitat loss, poaching, and illegal trade – and yet they often sensationalize tiger attacks, painting a picture of bloodthirsty beasts preying on innocent humans.
- “We must learn to live harmoniously with nature, not try to dominate it. This includes recognizing the power of the media to shape our perceptions and using that power responsibly to foster coexistence,” a Bangladeshi journalist argues in a new op-ed.
- This post is a commentary, the views expressed are those of the author, not necessarily Mongabay.

Bangladesh to formalize fire mitigation plans for Sundarbans as burning risk rises
- A recent fire in the eastern Sundarbans of Bangladesh has highlighted the rising risk of burning in the world’s biggest mangrove forest.
- The Bangladesh government says it’s drawing up guidelines to address the problem, which is attributed largely to human activity.
- A major factor for the fire risk is the drying out of the creeks and canals that crisscross through the Sundarbans, a consequence of embankments that were built to keep out seawater but that have also led to the buildup of river-borne silt.
- In 2022, Bangladesh began imposing a three-month ban, from June through August, on people entering the Sundarbans, but the policy has been widely criticized as unfair.

Bangladesh island’s switch from solar power to fossil fuels threatens birds
- The Bangladesh government recently converted off-grid Nijhum Dwip Island in the Bay of Bengal into an on-grid locality powered by fossil fuel-fired plants, posing a threat to the country’s second-largest mangrove forest.
- The island’s inhabitants had depended on individual solar-run power, and the government planned to install a mini solar grid for an uninterrupted power supply a few years back.
- Instead, the government has facilitated the construction of a 15 megawatt heavy-fuel-run power plant at Hatiya, the subdistrict headquarters of Nijhum Dwip, under the ‘100% Reliable and Sustainable Electrification Project,’ which seems to be a reverse transition from renewable to fossil fuel-based electrification.
- Nature conservationists believe that due to the connection to the national grid, human activities will increase around the forest and endanger the already cornered wildlife of the national park on the island.

Bangladeshi farmers find zucchini’s high yields & low costs palatable
- Though long considered “foreign” to Bangladeshi farmers, zucchini squash is now cultivated among growers who value its high productivity, lower production cost and short growing time.
- Farmers living in dry regions and river islands prefer to cultivate this vegetable, where watering the plant is an issue.
- Bangladesh Agricultural Extensions expects more zucchini squash cultivation in the coming days based on farmers’ enthusiasm and growing local demand in the market.

Rocky rollout for Bangladesh’s ambitious solar-powered irrigation plans
- Nearly half of irrigation costs in Bangladesh are due to irrigation, and the diesel pumps that currently power irrigation networks are responsible for 1.6% of the country’s greenhouse gas emissions.
- To address both issues, the government is rolling out a nationwide program to gradually replace these diesel pumps with solar-powered ones, aiming to slash irrigation-related emissions by 0.8 million metric tons by 2030.
- It also says that given that irrigation use is concentrated in the non-monsoon months, the surplus energy generated by the pumps the rest of the time can be fed into the grid, providing up to 480 gigawatt-hours of clean energy a year.
- In pilot programs, however, farmers have expressed concern over the reliability of the solar pump systems, especially for water-intensive crops such as rice and corn, and have also noted that their irrigation costs remain the same.

In Bangladesh, olive ridley turtles break 4-year record with 53% increase in eggs
- Bangladesh has seen the highest number of olive ridley turtle eggs this year, a conservationist group says.
- The olive ridley’s main nesting ground is different islands of the country’s southeastern district, Cox’s Bazar, in the Bay of Bengal.
- The key reasons behind the success are extensive conservation action across beaches and an awareness program among local people.
- Conservationists say they believe success might decline if the current pace of tourism and related infrastructure development is not checked, as they appear to disturb ecosystems.

Navigating the rise in conflicts between humans and fishing cats in Bangladesh
- In Bangladesh, rapid village expansion shrinks wetlands, forcing fishing cats (Prionailurus viverrinus) closer to humans. This triggers human-cat conflicts occurring every two weeks, with over half of them ending in a cat’s death.
- The main reason for the killings is fear. Locals often mistake fishing cats for tigers and feel threatened. Social pressure to participate in killings and revenge for livestock losses (often caused by other animals) further fuel the conflicts.
- Despite ongoing threats like infrastructure projects that fragment habitats, some hope exists. Government awareness campaigns and dedicated nongovernmental efforts are educating communities and finding solutions to promote peaceful coexistence with fishing cats.

Forest officer’s killing highlights Bangladesh authorities’ waning power
- The recent killing of a forest officer by illegal quarriers in Bangladesh has raised questions about the effectiveness of law enforcement amid intensifying encroachment into protected forests.
- Sajjaduzzaman, 30, was struck by the quarriers’ truck after confronting them for digging up a hillside in the southern district of Cox’s Bazar.
- Attacks on forest officers by people illegally logging, quarrying, hunting or carrying out other forms of natural resource extraction are a long-running problem, with around 140 officers attacked over the past five years.
- Experts have called for a more coordinated approach from various government law enforcement agencies to support the Forest Department in keeping encroachers out of protected areas.

Bangladesh uses satellite transmitters on saltwater crocodiles in Asia’s first
- On March 13, the Bangladesh forest department tagged satellite transmitters on two saltwater crocodiles for the first time in Asia and released them in the Sundarbans waters.
- So far, four saltwater crocodiles — three from captivity and one from the wild — have been tagged and the preparation is in place to tag more.
- The forest department has already started collecting data using the satellite transmitters to understand the crocodile’s habits in this ecosystem and identify nesting its hotspots, ecology, mortality rate and habitat range.
- Experts say the satellite data will play an important role in crocodile conservation in Bangladesh, where the species is critically endangered, and will help the authorities make proper conservation management plans to protect it.

Beneath the surface, a toxic tide threatens Bangladesh’s water lifeline
- Despite widespread water access, millions in Bangladesh lack safe drinking water due to contamination by arsenic, salinity and heavy metals as unveiled by the nation’s first comprehensive report on groundwater quality assessment.
- Depletion of groundwater, driven by irrigation and exacerbated by climate change, intensifies contamination, particularly affecting coastal areas with saltwater intrusion and surpassing safe limits in certain regions.
- Freshwater pockets and deep aquifers provide temporary relief, but experts emphasize that long-term strategies are imperative to address the problem in coastal districts.
- The Bangladeshi government’s commitment to water issues is evident, but urgent global cooperation, improved infrastructure and data-driven solutions are essential for ensuring safe water access nationwide.

Despite investment in conservation, Bengal tigers still struggling in Bangladesh
- As a major tiger habitat country, Bangladesh has been spending a remarkable amount of money to protect the Bengal tiger (Panthera tigris tigris) for the last two decades; however, the population of the big cat has dropped during this period.
- According to the last survey conducted in 2018, only 114 tigers remain in the Bangladesh portion of the Sundarbans, compared to 440 in 2004.
- In Bangladesh, Sundarbans is the only place where the Bengal tiger lives. Three portions of the mangrove forest are designated as wildlife sanctuaries, but none are specifically dedicated to the tiger.
- Experts blame inefficient and inadequate measures in conservation initiatives as the major reasons for the failure in population increase.

Comeback on the cards for Asian antelope declared extinct in Bangladesh
- Nilgais, the largest antelope species in Asia, are reappearing in northwestern Bangladesh, a country that was part of their historical range but where they were declared locally extinct in the 1930s due to habitat loss and hunting.
- Forays by nilgais, mostly from neighboring India but also from Nepal, suggest that the species can be reestablished in parts of Bangladesh that still have sufficient areas of undisturbed natural landscape.
- A 2023 study identified 13 instances of nilgai sightings in the country from 2018-2022 from media reports, but it’s likely that most sightings are going unreported because they end up in local residents catching and killing the antelopes for their meat.
- Experts say any attempt to reestablish a nilgai population within Bangladesh’s borders should be carried out in tandem with a public education campaign to discourage the hunting of the animal.

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.

As lightning strike fatalities increase, Bangladesh still has no reliable preventive measures
- Between 2011 and 2020, lightning strikes claimed the lives of 2,164 people, or nearly four people every week, in Bangladesh, according to the country’s disaster management department. However, a Bangladeshi NGO reports at least a thousand more lightning related fatalities between 2010 and 2021.
- Researchers linked the increased frequency of lightning with climate change; as for the increased death toll, they blamed the government’s inefficient protection measures, including the lack of tall trees.
- To reduce the number of fatalities, the government has started working on long-term solutions, such as installing lightning arresters and growing palm trees. Nevertheless, a significant sum of money is being squandered and nothing functions as expected, say experts.

Herbicide used in Bangladesh tea production threatens biodiversity & health
- Tea is Bangladesh’s second-largest cash crop after jute, producing more than 60,000 tons (60 million crore kilograms) annually.
- To rid tea gardens of weeds, producers are using the harmful chemical glyphosate, mainly under the brand name Roundup, as an herbicide; the chemical is banned in 33 countries due to its negative impacts on biodiversity.
- Despite concern among agriculturists and environmentalists, the government has yet to take any initiative to control the use of harmful chemicals.

As climate disasters claim their children, Bangladeshi mothers seek safety in bigger families
- Climate change is exacerbating child mortality in flood-prone areas of Bangladesh, prompting mothers to have larger families as a response to the fear of losing children to disasters.
- Studies indicate an 8% surge in infant mortality risk in flood-prone regions, resulting in more than 150,000 lives lost between 1988 and 2017.
- While Bangladesh has seen improvements in disaster management, reduced cyclone deaths, and progress in health for mothers and children, climate change poses new threats, especially to vulnerable coastal communities lacking adequate protection.
- A National Adaptation Plan offers solutions such as water conservation and livelihood opportunities, but challenges like funding, coordination and transparency need attention for effective implementation, experts say.

In Bangladesh, sunflower grows where other crops don’t amid increasing salinity
- The changing climate, rising sea levels and other anthropogenic factors are forcing a vast area of Bangladesh’s coastal zone to remain barren due to the presence of salinity in arable land.
- Overcoming these hurdles, coastal farmers, with the support of the government and various nongovernmental organizations, are now farming sunflowers and benefiting from the alternative crop.
- Bangladesh currently produces only 10% of the oilseeds it uses; imports from different countries meet the rest of the demand.
- The government estimates that the country could produce sunflower to meet the local demand for cooking oil by up to 26% by cultivating the oilseed in saline-prone zones.

Overfishing leads to decline in Bangladesh marine fish stocks & diversity
- Bangladesh is facing a decline in marine fish stocks and diversity due to lack of knowledge among fishers, proper implementation of the Marine Fisheries Act and rampant use of industrial trawlers and unauthorized fishing gear in permitted fishing zones.
- The country has a 710-kilometer (440-mile) coastline with 121,110 square kilometers (46,760 square miles) of exclusive economic zones (EEZs) within the Bay of Bengal and is a hub of 740 aquatic species.
- The marine fisheries sector contributes about 15% of Bangladesh’s total fish production, which helps meet the population’s demands for animal protein.

Bangladeshi farmers eye moringa as a climate and economic solution
- Farmers in Bangladesh are increasingly turning to the fast-growing, drought-resistant moringa (Moringa oleifera) tree, which is indigenous to South Asian nations such as India, Pakistan, Bangladesh and Afghanistan.
- Researchers say moringa is beneficial for human health, as both the leaves and the fruits are rich in nutrients and minerals.
- Researchers also suggest that moringa cultivation could be a part of smart agriculture as climatic patterns change, as the plant can tolerate extreme heat and cold.
- A Bangladeshi entrepreneur has been working to create a social movement and entrepreneurship in moringa cultivation and marketing since 2017; so far, he has engaged some 5,000 farmers in 20 districts of Bangladesh.

Indigenous effort in Bangladesh helps reverse endangered fish’s slide to extinction
- Unchecked logging and quarrying of rocks from streambeds in Bangladesh’s Chittagong Hill Tracts led to springs drying up and populations of putitor mahseer fish, an endangered species, disappearing.
- The situation was worsened by climate change impacts, characterized here by a more intense dry season during which even streams that once ran year-round now dry up.
- A project launched in 2016 and backed by USAID and the UNDP is working with Indigenous communities to reverse this decline, starting with efforts to cut down on logging and quarrying.
- As a result of these efforts, areas where forests have been conserved have seen the flow of springs stabilize and populations of putitor mahseer and other fish revive.

Western hoolock gibbon conservation in Bangladesh urgently needs funding (commentary)
- Western hoolock gibbons play an important role in seed dispersal for forest regeneration in northeastern India, western Myanmar, and eastern Bangladesh.
- But the species is among the world’s most threatened primates, and faces a host of threats in Bangladesh ranging from deforestation for agriculture to the illegal wildlife trade.
- These animals “urgently require a comprehensive program that not only focuses on habitat conservation but also on scientifically sound translocations of isolated groups and individuals….Without significant financial support, the survival of Bangladesh’s gibbons remains in jeopardy,” a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.

Prevention is best defense against Bangladesh crop diseases, researchers say
- Two staples — paddy and wheat — and one cash crop, jute, are the major focus areas of researchers and scientists in Bangladesh due to their importance to food security and the economy.
- However, state research institutes say these crops are damaged by five main crop diseases, which could trigger a yield loss of up to 62% annually if outbreaks occur frequently.
- Researchers suggest various approaches, including natural pest control, that could ensure a healthy ecosystem for crop cultivation and reduce the cost of farm production.

Elite appetite turns Bangladesh from source to consumer of tiger parts
- Previously a source country for live tigers and their parts, Bangladesh has transformed into both a consumer market and a global transit hub for the illegal trade, a new study shows.
- The shift is fueled by local demand from a growing elite, global connections, and cultural fascination with tiger products, and facilitated by improved transport infrastructure networks that have allowed two-way flow of tiger parts through Bangladesh’s airports, seaports and land border crossings.
- Despite some progress in curtailing tiger poaching and smuggling over the past two decades, enforcement remains weak and poaching continues, especially in the Sundarbans mangrove forest.
- Experts say there needs to be broader collaboration among state agencies, international organizations and other countries to combat wildlife trafficking more effectively.

Could mugger crocodiles be brought back from regional extinction in Bangladesh?
- Once, mugger crocodiles (Crocodylus palustris) were common in Bangladesh’s major rivers, including the Padma, Jamuna, Meghna and most of their tributaries, but the species is thought to have gone extinct in the country due to unchecked poaching for its prized skin.
- Although the IUCN in 2000 declared the mugger regionally extinct in Bangladesh, three adult muggers were recovered from the country’s river and water bodies in only 11 days, Oct. 17-28 this year.
- The crocodiles were taken to the Karamjol Crocodile Breeding Centre in Khulna, and authorities are working on how muggers could be brought back to nature by increasing their population through captive breeding.
- Experts suggest establishing a safe zone for the crocodiles in the upper Padma River.

Hunters & habitat loss are key threats to red serow populations in Bangladesh
- The red serow population (Capricornis rubidus, a type of goat-antelope) has rapidly declined in Bangladesh due to hunting for meat and habitat loss; 50% of the animals’ habitat has been severely degraded over the last 10 years.
- Recent camera-trap surveys find the existence of red serows in Baroiyadhala National Park in Bangladesh.
- Some 22 cameras captured images of red serows, creating hope for its conservation, but the cameras also captured pictures of roaming armed hunters.
- Experts suggest taking conservation measures in the rocky mountain areas of Mirsharai, Sitakunda and Hazarikhil in Chattogram to revive the population of wild goats.

Banana fiber sari offers sustainable, biodegradable alternative in Bangladesh
- The sari, a quintessential part of Bangladeshi culture and attire, is known for its vibrant colors and intricate designs.
- However, traditional sari production is often associated with resource-intensive processes that raise environmental concerns.
- A couple of Indigenous Marma and Manipuri communities in Bangladesh have taken the Bangladeshi fashion scene by storm with their unique creation: a sari woven entirely from banana fiber, considered a sustainable and biodegradable alternative.

Bangladesh survey records invasive alien plants threatening protected forests
- According to a survey, 44 exotic invasive plant species were recorded in five protected forests in Bangladesh. Of them, seven species were found to be harmful, with significant environmental impacts on protected forest areas.
- As a signatory of the Convention on Biological Diversity (CBD), the country is committed to protecting ecosystems and biodiversity of flora and fauna.
- To check the number and reduce the negative impacts of the identified alien invasive plant species on ecology and environment, the government has taken five strategic management plans.

Seaweed: The untapped economic potential for Bangladesh
- Bangladesh currently produces some 400 tons of seaweed, valued at 55 million taka (about $500,000), while a study suggested the country could produce 50 million tons of seaweed annually by 2050.
- Despite the potential to grow and earn more foreign currency through export, the sector is dealing with a number of difficulties, including inadequate investment as well as proper guidelines and regulations.
- According to the Food and Agriculture Organization (FAO), seaweed farming is one of the fastest-growing aquaculture sectors globally, with an annual production of about 33 billion tons, valued at $11.8 billion.

Habitat loss drove long-tailed macaques extinct in Bangladesh, experts say
- Clearing of mangrove forests along the Naf River in southern Bangladesh was the main driver for the extinction of the long-tailed macaque in Bangladesh, according to longtime experts on the species.
- From an estimated 253 of the monkeys in 1981, the population plunged to just five individuals in 2010, then three in 2012, before it was declared extinct in the country in 2022.
- Experts attribute this trend to the clearing of mangroves for shrimp farms, farmland, refugee camps, and settlements.
- Though one of the most widely distributed monkey species in the world, the long-tailed macaque faces severe threats throughout its range, and since 2020 has seen its conservations status progressively worsen from least concern to vulnerable to endangered.

Salinity hinders Bangladesh agriculture; groups respond with seeds & information
- Bangladesh is the fourth-highest rice-producing country in the world, but much of that production is threatened by salinity.
- More than 30% of the cultivable land in Bangladesh is in the coastal area; a comparative study of the salt-affected area showed that of 2.86 million hectares (7.1 million acres) of coastal and off-shore lands, about 1.056 million hectares (2.6 million acres) — an area roughly the size of Lebanon — of arable lands are affected by varying salinity, hampering agricultural production.
- In the coastal zones, farmers mainly cultivate low-yielding, traditional rice varieties during the wet season, while in the dry season (January- May), most of the land remains fallow because of soil salinity.
- To cope with the situation, government and nongovernmental organizations are introducing different types of saline and extreme weather-tolerant crop varieties to use the farmland yearly.

Bangladesh apparel industry makes progress in ‘eco-friendly’ manufacturing
- According to the United Nations Environment Programme (UNEP), the fashion industry is responsible for 10% of carbon emissions annually. If the current pace of greenhouse gas emissions continues, it will surge by more than 50% by 2030.
- Bangladesh, the second-largest exporter in the $45 billion ready-made garment (RMG) industry with a 7.9% of the global market share and 4.4 million employees, mostly rural women, are very cautious in limiting the environmental impacts and carbon emission through its green initiatives.
- In the last 15 years, Bangladesh has set an example of green and sustainable manufacturing by establishing numerous certified green factories.
- Since 2009, Bangladeshi apparel and textile manufacturers have established 202 “eco-friendly” factories certified by the U.S. Green Building Council (USGBC), the highest in the world.

Sundarbans tiger and prey numbers rise amid Bangladesh conservation efforts
- Recent surveys of big cats and prey in the Sundarbans indicate that numbers for both have increased significantly in recent years, thanks to different conservation measures taken by the Bangladesh government.
- According to the last survey conducted in 2018, there were 114 tigers in the Bangladesh portion of the Sundarbans, while the number counted in 2004 was 440.
- An ongoing camera trapping tiger census has found more presence of tigers across the forest than in earlier counts. The final count of the tiger population will be announced on International Tiger Day, July 29, 2024.
- Experts say that an increase in tigers’ prey animals will reduce human-tiger conflict and help increase the tiger population.

Court order fails to stop poison fishing in Bangladesh Sundarbans
- According to the Bangladesh Forest Department, the Sundarbans mangrove forest in Bangladesh shelters about 210 species of white fish, 24 species of shrimp, 14 species of crabs, 43 species of mollusks and one species of lobster.
- About 1.7 million locals living adjacent to the mangrove forest directly or indirectly depend on forest resources, including fish and crabs, for their livelihood due to the region’s growing unemployment rate.
- Among them, some fishers have been using poison to catch fish, even during the banned period, which eventually damages forest ecology and the health of those who consume the fish caught with poison.
- Considering these damages to the world’s single largest mangrove forest as well as to human health, the Bangladesh High Court issued a verdict responding to a writ petition to stop the heinous practice in September 2021, though the practice is still ongoing.

A thriving online market for wild birds emerges in Bangladesh
- Mongabay discovered up to 10 YouTube channels, Facebook groups and profiles selling wild birds online, despite the illegality of capturing, caging and selling wild birds under the Wildlife Conservation and Security Act of 2012.
- Due to lax laws and limited authority of the Wildlife Crime Control Unit (WCCU), online dealers of wild birds can obtain quick bail and continue with their operations, which encourages more people to enter the trade; an online ecosystem to bring in more offline traders to the online marketplace has developed as a result.
- Hunting, capturing and selling wild birds raises the possibility of zoonotic disease transmission; according to the World Economic Forum, zoonotic diseases result in 2.5 billion cases of human illness and 2.7 million human fatalities each year.

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.

When it rains, it pours: Bangladesh wildlife trade booms during monsoon
- The illegal wildlife trade in Bangladesh increases during the wet season due to a shortage of livelihoods and poor surveillance, a study has found.
- Killing and trading wildlife has been illegal in Bangladesh since 2012, but a culture of hunting means the problem still persists, wildlife officials say.
- Wildlife markets trade in animals and parts from species such as tigers and crocodiles, with the more lucrative end of the trade thriving in areas with a weak law enforcement presence and close proximity to a seaport or airport.
- Efforts to tackle the trade are limited by law enforcement restrictions, with the Wildlife Crime Control Unit (WCCU) lacking the authority to arrest suspects and reliant on local agencies for investigations and legal action.

As Bangladesh’s crab fishery booms, its wild stocks suffer the fallout
- Crab harvests in Bangladesh are booming to meet thriving export demand, but the rates at which wild stocks are being depleted may be unsustainable, experts warm.
- Researchers say the loss of large numbers of mud crabs from ecosystems like the Sundarbans mangroves could trigger an ecological imbalance.
- Bangladesh exported about $35 million worth of crabs in the 2019-2020 fiscal year, with the trend expected to increase to markets like the U.S., the EU and Singapore.
- Experts have called for more efforts to hatch crabs on aquafarms as a way to ease the pressure on wild stocks, but this option isn’t available yet at commercial scale.

Bangladesh ramps up use of recycled fabrics in ready-made garments
- Aligning with the European Union’s target to reduce the use of fresh cotton in the garment sector to reduce the environmental degradation, Bangladesh is increasing the use of recycled materials in its ready-made garment sector.
- The sector accounts for the country’s major share of export earnings, with a value of more than $27.9 billion in exports in the 2019-20 financial year.
- The country currently relies heavily on imported textile fiber; in 2019, almost half of RMG waste was pure cotton.
- Interestingly, many local companies are running recycling plants to meet the gradually increasing demand for recycled cotton fiber.
