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.

Bangladesh orchid losses signal ecological imbalance, researchers say
- Bangladesh has lost 32 orchid species from nature in the last hundred years out of 188 once-available species.
- Habitat destruction, overharvesting, and indiscriminate collection for sale in local and international markets cause the disappearance, researchers say.
- Considering the unique position of orchids in the ecosystem and their herbal, horticultural and aesthetic value, researchers consider this loss alarming.

Bangladesh ‘Village of Herbs’ profits from planting rather than cutting trees
- According to the World Health Organization, 88% of all countries are estimated to use traditional medicine; more than 40% of pharmaceutical formulations are based on natural products, and many landmark drugs originated from traditional medicine.
- According to the Bangladesh Agricultural Research Institute, there are 722 species of medicinal plants in Bangladesh.
- Locals who once cut down trees are now actively planting and cultivating medicinal trees. Large pharmaceuticals, Ayurvedic, and Unani medicine manufacturers collect raw materials from this market.

Bangladesh ramps up freshwater fish conservation in bid for food security
- Bangladesh is reviving 39 native freshwater fish species through hatchery breeding, in an effort to secure stocks of commercially important fish.
- A quarter of the freshwater fish found in Bangladesh are threatened with extinction, according to a 2015 assessment, largely as a result of habitat loss, overfishing and pollution.
- In response to the decline, the Bangladesh government is breeding several species in captivity and distributing the fry for free to fish farmers.
- Bangladesh produces 4.6 million metric tons of fish a year, and is the No. 3 producer of freshwater fish globally.

Extreme temperatures and erratic weather disrupt Bangladesh’s famous Rajshahi silk industry
- Since the 13th century, Rajshahi, named “Silk City,” has been known for its finest silk, which local growers have produced.
- Earlier, the product was named Bengal silk or Ganges silk. Considering the prospects and reputation of the trade, the then-Pakistan government started producing silk officially. Consequently, it established a silk factory in Rajshahi in 1961, which washanded over to Bangladesh Sericulture Development Board in 1978.
- The silk sector in Rajshahi grew as farmers of the neighboring districts used to produce high-quality silk yarns by the larvae of moths fed on fresh mulberry leaves, which were later used for luxurious clothing items. There are three types of silk produced in Rajshahi: mulberry, endi and tassar, with mulberry silk being the finest and most expensive.
- However, Bangladesh’s once-famous silk industry has faced difficulties in recent years, including the excessive dependency on imported low-cost yarn and different bacterial and viral diseases triggered by constantly variable temperatures and humidity.

Bangladesh’s new red list of plants shows country has already lost seven species
- Bangladesh’s first-ever red list of plant species shows the country has lost seven species in the last century and now risks losing at least another five.
- Researchers involved in the assessments of the conservation status of 1,000 species cited climate change, pollution, deforestation, and poor management of protected areas as major drivers behind the ecological damage.
- The Bangladesh Forest Department is working to protect native plant species through large-scale planting efforts across the country.

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.

In Bangladesh, microplastic threat to frogs is also concern for rice farming
- Researchers have found microplastics in 90% of frogs sampled from the Bengal Delta in Bangladesh.
- The finding raises concerns about the freshwater ecosystem health and rice cultivation, given that frogs are a key “natural insecticide” keeping pest numbers in check.
- The study adds to a growing body of literature on the prevalence of microplastic pollution in Bangladesh.
- Nearly a tenth of the 8,000 metric tons of trash generated daily in the country is plastic waste, for which there’s no proper disposal.

Climate change, human pressures push Bangladesh’s ‘national fish’ into decline
- Bangladesh’s all-important hilsa fishery is declining amid pressures from human-driven factors and climate change, experts and authorities warn.
- The fish, Tenualosa ilisha, contributes around 12% of the total fish catch in Bangladesh, and the fishery employs at least 2.5 million people across the country.
- Several government conservation initiatives, including declaring six hilsa sanctuaries and two fishing bans during the year, have helped boost production in the past two decades.
- However, pressures persist, including rising salinity levels in the rivers where the fish spawn, discharge of pollution and agricultural runoff, and disruptions to water flow as dams are built upstream.

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.

Bangladesh tries fences to tackle growing human-tiger conflict in Sundarbans
- About 300 people and 46 tigers have been killed since 2000 in human-tiger conflicts in Bangladesh’s Sundarbans.
- Authorities here have decided to install fencing along the rivers and canals that the big cats use to cross into human settlements.
- Experts point to a successful application of this measure in the Indian Sundarbans, and say the fencing will both keep tigers out of human settlements, and humans and their domestic animals out of tiger habitat.
- The Sundarbans is the only mangrove habitat in the world that supports tigers, but the ecosystem continues to be degraded due to human and natural causes.

In north Bangladesh, human-elephant conflicts signal need for greater protection
- At least four people have been killed in wild elephant attacks in Bangladesh in the last few weeks, three of them in the northern Sherpur district.
- At least one elephant was also killed by locals via electrification after a herd of wild elephants roamed the area for food.
- Of the 12 elephant corridors in Bangladesh, Sherpur is the only corridor that has seen a rise in attacks, as the government and other conservation organizations focused their efforts in the southern zone, where the other 11 corridors are located.
- Conservationists blame the scarcity of adequate resources and funding for proper management of conservation activities, resulting in the continuation of conflicts and killings.

Record year for olive ridley turtles in Bangladesh as conservation work pays off
- Bangladesh has recorded the highest number of olive ridley turtle eggs this nesting season, a conservationist group says.
- The species’ main nesting grounds in Bangladesh are the various small islands off the southeastern district of Cox’s Bazar in the Bay of Bengal.
- Extensive conservation action across the area and the awareness programs carried out among local communities are the key reasons behind the success.
- However, the growth of the tourism industry and infrastructure development continue to pose major threats to the turtles and their nesting grounds.

Fewer migratory birds stopping at key Bangladesh wetland amid human disturbances
- Numbers of most species of migratory waterbirds in Bangladesh’s Tanguar Haor wetland, a key stopping point, have fallen over the past 15 years, a new study shows.
- The cause of the decline isn’t fully known yet, researchers say, but it’s clear that human activity has impacted the wetland, with 40% of the basin’s original area converted to farmland and settlements in just 30 years.
- The study recommends prioritizing conservation at two of the permanent waterbodies, or beels, in the Tanguar Haor complex, citing the high abundance and diversity of the birds that stop there.
- Tanguar Haor is the second Ramsar site in Bangladesh, after the Sundarbans mangrove forest, and accounted for nearly half of the more than 1.2 million waterbirds recorded in the country between 2008 and 2015.

Dhaka faces manifold problems as water bodies diminish
- A study by the Bangladesh Institute of Planners, or BIP, says the capital has lost 36% of its water bodies since 2010.
- Dhaka city has experienced water scarcity during dry months, which puts a strain on firefighters as they battle large fire; during monsoon months, the city experiences regular waterlogging as water retention points fill up.
- The disappearance of water bodies has created multifaceted problems like rising water levels, airborne disease, and mosquito-related diseases.
- In 2000, the government passed the Natural Water Reservoir Conservation Act, which mandates that natural water bodies be kept intact.

‘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.

Bangladesh’s vultures still threatened by poison despite conservation actions
- The discovery of 14 dead vultures in an area of Bangladesh considered safe for the scavenging birds has highlighted the persistent threats to the birds despite ongoing measures to protect them.
- The vultures are thought to have died after feeding on a goat carcass laced with poison, which local residents had left out for feral dogs and jackals that had killed their livestock.
- Vulture populations across South Asia were decimated in the 1990s by the widespread use of the cattle painkiller diclofenac; birds that fed on dead cattle that had been treated with the drug died of severe poisoning.
- Bangladesh has since banned diclofenac and ketoprofen, another livestock painkiller deemed poisonous to vultures, and established vulture-safe zones around the country in an effort to boost their populations.

Resurgence of deadly Russell’s viper prompts Bangladesh to develop antivenom
- Reports of bites from Russell’s viper, the deadliest snake on the Indian subcontinent, have increased in Bangladesh since 2013.
- At least 20 deaths were recorded from 17 of Bangladesh’s 64 districts between 2013 and 2016, all attributed to Russell’s vipers.
- Researchers attribute this to improvements in farming intensification, which means rats — the snake’s prey of choice — are present in crop fields year-round, whereas before they were only there for part of the year.
- Snakebites are a significant cause of illness and mortality in Bangladesh, with an estimated 6,041 deaths annually, but Bangladesh still relies on imported antivenom — although a newly established Venom Research Centre aims to address this shortcoming and boost research on the country’s venomous snakes.

Red coral kukri sightings in Bangladesh prompt call to save rare snake habitat
- The red coral kukri (Oligodon kheriensis) is endemic to a small region of the Himalayan tracts of northern India and Nepal; the snake species was first spotted in Uttar Pradesh in India in 1936.
- For the first time, the rare species was found in Bangladesh on Oct. 27, 2020, while locals were digging soil in a bamboo bush in Panchagarh district; this indicates an expansion of the snake’s distribution range.
- In northern Bangladesh, land use patterns have changed, making forests highly fragmented, indicating that habitat loss, forest degradation and fragmentation are major threats to the species.
- Experts suggest taking immediate conservation measures in the areas where the red coral kukri is found by imposing specific measures to stop the destruction of bamboo bushes and forests.

Amid changing climate, Bangladesh farming groups conserve indigenous rice seeds
- Bangladesh, the fourth biggest rice-producing country in the world, produces around 39 million tons of rice annually to feed its 170 million people, with 130 lab-developed high-yielding varieties.
- For higher production, farmers have turned to a few high-yielding varieties, despite having around 1,000 indigenous varieties that have better adaptive quality amid changing climatic patterns; the trend has forced many traditional varieties to go extinct.
- By cultivating indigenous rice varieties, some farmers are fighting back against monoculture, and a few nongovernmental conservation organizations, as well as individuals, are creating awareness about protecting local varieties.
- Bangladesh Resource Center for Indigenous Knowledge (BARCIK) alone is conserving more than 600 local rice varieties and engaging with farmers across the country.

Jashodhon Pramanik: The farmer guardian of birds in Bangladesh
- Jashodhon Pramanik, a farmer from Natore, Bangladesh, has initiated a bird conservation movement.
- His 23 years of activism led to the banning of air guns, the creation of bird sanctuaries in every district and the creation of watering holes for birds.
- His one-man initiative Pokkhikuler Asroy O Khaddo Nischitkaron Prokolpo (Project for Ensuring Food and Shelter for Birds) influenced the government to make more than 30 decisions in favor of protecting birds.

Is it safe to eat? Bangladesh fish exposed to hormones, antibiotics and toxic waste
- Bangladesh has recently achieved remarkable success in freshwater fish production, with more than 1.25 million metric tons of freshwater fish produced in 2020.
- The use of antibiotics in fish culture and hormones in artificial fish breeding bring into question the safety of Bangladesh’s food supply, as exposure to high levels of these substances can harm human and environmental health.
- Research shows that 88% of fish farmers do not have proper knowledge of antibiotics use, and 81% are unaware of effective chemical dosages in fish farming.
- In addition, toxic industrial wastes containing heavy metals released into the aquatic environment may enter the food chain through biomagnification and may cause various health problems in humans.

Bangladesh bans suckermouth catfish in light of threats to native fish species
- Considering its aggressive breeding nature and the threats the species poses to native fish populations, the Bangladesh government has recently banned suckermouth fish.
- The suckermouth catfish is mainly an aquarium species that was imported into Bangladesh in the 1980s as an ornamental fish and later introduced into water bodies that are home to the country’s main sources of native fish.
- However, in recent years, the number of suckerfish has increased manifold as local fish species have decreased.
- Earlier, in 2002, Bangladesh banned two other fish species: African catfish and piranhas.

For key Bangladesh wetland, bid for Ramsar status is no guarantee of protection
- Bangladesh has proposed designating a third Ramsar site in the country, but the current state of its two other important wetland ecosystems suggests such a designation won’t be of much protection.
- The Sundarbans, the world’s biggest mangrove forest, and Tanguar Haor, a freshwater swamp forest, have been severely degraded by deforestation, hunting of wildlife and fish, overexploitation of natural resources, and water pollution.
- Hakaluki Haor, the largest marsh wetland ecosystem in South Asia, which the government wants designated a Ramsar site, is already facing similar threats.
- “The problem is, the government does nothing after the recognition. They completely fail to take necessary measures, in the interest of vested quarters in the government,” says environmental lawyer Syeda Rizwana Hasan.

Banned but abundant, gillnets pose main threat to Bangladesh’s river dolphins
- Bangladesh is home to around 2,000 Ganga River dolphins and 6,000 Irrawaddy dolphins, found mostly in the Sundarbans, the world’s largest mangrove forest.
- Both species, considered threatened on the IUCN Red List, run a high risk of entanglement in the gillnets used by local fishers.
- Gillnets are banned in Bangladesh, but remain popular among local fishers, with the government unable to crack down on their use.
- To conserve the freshwater dolphins, the government has embarked on a 10-year action plan that includes declaring more areas as dolphin sanctuaries and raising awareness among fishers.
