Environmental, Forest and Climate Change, and Water Resources Advisor Syeda Rizwana Hasan has warned that many river-based infrastructure projects are inflicting irreversible environmental damage by ignoring rivers as living systems. Speaking virtually at a sub-regional workshop on ‘Water and Climate Resilience in the Hindu Kush Himalaya’ held in Kathmandu, she highlighted that despite having policies and institutions, implementation gaps remain a major obstacle in South Asia. Rizwana emphasized the need for fair water sharing, river rights, and disaster risk management among Himalayan countries. She noted that 90% of Bangladesh’s rivers originate upstream, making the nation highly vulnerable to transboundary impacts such as floods, droughts, and salinity. Citing Bangladesh’s accession to the UN Water Convention, she called for stronger cooperation in data sharing and early warning systems. Rizwana also praised Nepal’s river restoration efforts and stressed that rivers are living entities whose rights must be protected through accountability and regional trust-based hydropower collaboration.

More than 60,000 African penguins have died from starvation along South Africa’s coast, according to a new study published in the journal Ostrich: Journal of African Ornithology. The research found that between 2004 and 2012, over 95% of penguins at key breeding sites on Dassen Island and Robben Island vanished due to lack of food during molting periods. The decline is attributed to climate change and overfishing, which have drastically reduced sardine populations—the penguins’ main food source. Scientists from the University of Exeter’s Centre for Ecology and Conservation warn that similar declines are occurring elsewhere. Over the past 30 years, the African penguin population has dropped by about 80%, and the species was declared critically endangered in 2024, with fewer than 10,000 breeding pairs remaining. Changes in ocean temperature and salinity have disrupted sardine spawning, while fishing pressure continues to rise, worsening the crisis for these seabirds.

A persistent cold wave has gripped Kurigram district for the past five days, severely disrupting daily life. The temperature dropped to 13.3°C on Friday, according to the Rajarhat Agricultural Weather Observatory. The biting cold and chilly winds have confined many residents, especially those living on the riverine islands (chars), to their homes. Day laborers, elderly people, women, and children are among the worst affected, as outdoor work has become nearly impossible. Many low-income families are struggling financially due to halted work opportunities. Residents report a lack of warm clothing, while cold-related illnesses such as fever and cough are spreading. Areas along the Brahmaputra River, including Ulipur, Chilmari, Roumari, and Char Rajibpur, are experiencing the harshest conditions. Authorities note that humidity levels remain high at 98%, with temperatures fluctuating between 12°C and 13°C over recent days.

Local authorities confirmed that transportation, electricity, and telecommunications systems across Akqi County remained fully operational. The CENC recorded the epicenter at 41.13 degrees north latitude and 78.40 degrees east longitude. While the tremor was strong, initial assessments suggest minimal impact on infrastructure or residents in the affected area.

Dhaka has been ranked as the most polluted city in the world among 126 cities, according to Swiss-based air quality monitoring organization IQAir. As of Thursday morning, the Air Quality Index (AQI) score for Dhaka stood at 302, placing it in the 'hazardous' category. Several areas, including South Pallabi (374), Eastern Housing (354), Madani Avenue’s Base Edgewater (334), and Kalyanpur (304), recorded extremely poor air quality. Other zones like Grace International School in Gulshan (287) and Pirerbag Rail Line (202) were marked as 'very unhealthy.' The high pollution level is primarily due to excessive fine particulate matter (PM2.5), which was found to be over 27 times higher than the World Health Organization’s safe limit. Jahangirnagar University area in Savar recorded the country’s worst air quality with an AQI of 412, while Khulna also reported hazardous levels at 302. IQAir classifies AQI above 301 as dangerous for human health.

Following a series of mild earthquakes across Bangladesh in the past 20 days, including a 4.1 magnitude tremor felt in Dhaka on Thursday morning, the Fire Service and Civil Defence Department has issued safety guidelines urging citizens to remain calm and follow specific precautions during seismic events. The advisory, released on November 23, outlines eight key actions: staying calm, seeking open spaces if on the ground floor, using the 'drop, cover, hold' method in multi-story buildings, avoiding elevators, turning off gas and electricity after tremors, keeping away from windows and heavy objects, staying clear of trees and poles outdoors, and avoiding damaged structures after quakes. Citizens are also advised to keep emergency items like torches, helmets, medicines, and whistles handy, and to contact the 102 hotline for emergency assistance. The department emphasized preparedness over panic to minimize risks and ensure safety during future tremors.

A severe cold wave has gripped Kurigram, a northern border district of Bangladesh, disrupting normal life as temperatures dropped to 12.4 degrees Celsius on Thursday morning. Dense fog and chilly winds have reduced visibility, forcing vehicles to operate with headlights even after sunrise. The cold has particularly affected low-income workers, day laborers, and those dependent on daily wages, who are struggling to continue their livelihoods amid the biting weather. Residents report that the combination of fog and cold makes it difficult to leave their homes, while transport and local businesses are suffering from reduced activity. According to Subal Chandra Sarkar, acting officer at the Rajarhat Weather Observatory, the temperature recorded at 6 a.m. was 12.4°C and may drop further in the coming days, indicating that the cold spell could intensify.

A mild earthquake measuring 4.1 on the Richter scale was felt in Dhaka early Thursday morning, December 4. According to the European-Mediterranean Seismological Centre, the quake originated about 20 kilometers east of Tongi and 3 kilometers north of Narsingdi, with a depth of approximately 27 to 30 kilometers. The tremor occurred at 6:14 a.m. local time and caused brief shaking across parts of the capital and nearby districts. No immediate reports of casualties or property damage have been received. This follows a series of recent minor quakes in Bangladesh, including a 4.2 magnitude tremor in the Bay of Bengal on December 2 and another felt in Cox’s Bazar and Chattogram on December 1. Authorities are monitoring the situation but have not issued any warnings, as the seismic activity remains within low-risk levels.

Following a series of earthquakes in November that rattled Bangladesh, experts are calling for the country to learn from Japan’s extensive experience in earthquake preparedness and resilience. Japan, located on the seismically active Ring of Fire, experiences around 1,500 earthquakes annually but minimizes casualties through strict building codes, public awareness, and regular drills. Japanese citizens are trained from childhood to respond calmly and effectively during tremors, while cities maintain clear evacuation routes and safe zones. Structural innovations such as seismic isolation, motion dampers, and flexible mesh frameworks help Japanese skyscrapers withstand strong quakes. In contrast, many smaller private buildings in Bangladesh fail to follow seismic codes, leaving them vulnerable. Experts emphasize that Bangladesh should prioritize awareness programs, regular earthquake drills in schools and workplaces, and enforcement of construction regulations. They also stress the need for political will to ensure urban safety and disaster resilience.

Bangladesh’s Fisheries and Livestock Advisor Farida Akhter emphasized the need for responsible harvesting, technological innovation, science-based policymaking, and effective governance to ensure sustainable marine development. Speaking at the second day of the international conference ‘Marine Fisheries and Blue Innovations: Safeguarding Ocean Harmony’ in Chattogram, she said that identifying the blue economy as a national priority has created opportunities for a sustainable ocean future through coordination among science, policy, and community development. Farida highlighted alarming declines in small pelagic fish stocks—down 78.6% in seven years—and the rise of jellyfish due to reduced predator fish, signaling ecological imbalance in the Bay of Bengal. She also warned that the hilsa fish, a national and global heritage species, faces serious threats. Farida called for regional and global cooperation to combat climate change and illegal fishing, and urged that research findings by Bangladeshi scientists be prioritized in policymaking for ecosystem protection and climate-resilient fisheries management.

At least 712 people have been confirmed dead and more than 500 remain missing after devastating floods and landslides struck Indonesia’s Sumatra Island last week, according to the National Disaster Management Agency (BNPB). The disaster has affected around 1.1 million people across three provinces, with North and West Sumatra suffering the worst damage. Communication and transportation links in areas like Tapanuli and Sibolga have been completely severed, hampering rescue and relief operations. Despite government and international aid being sent by air and sea, many remote villages remain cut off, leading to severe shortages of food and clean water. Reports of looting and unrest have emerged as desperate residents struggle to survive. Authorities have deployed police to maintain order and facilitate aid distribution. In response to the communication crisis, technology entrepreneur Elon Musk has announced free Starlink internet services to support emergency connectivity in the affected regions.
