For the first time in decades, fishermen along Assam’s Barak river are returning home with empty nets. The floods in June, which usually bring an abundance of fish, have instead left the river strangely barren. In Madarpur village of Cachar district, Abdul Kalam, a fisherman for 37 years, says he has barely caught anything in the past two months. “Usually floods mean more fish, but this time it feels like the river is dead,” he said. His daily earnings, which once reached up to ₹500 on a good day, have now dropped to less than ₹20. The crisis is affecting hundreds of families in Madarpur and neighbouring villages like Niz Haritikar. Once teeming with Hilsa, Rohu, Catla and Ritha, the river now yields only baby Hilsa, leaving many without a source of income. Veteran fisherman Lilar...

August 12, 2025 — A new global study has predicted glacier erosion rates with the highest precision yet revealing how ice is reshaping landscapes across the world. Published in Nature Geoscience, the research covers more than 180,000 glaciers and offers the first detailed estimate of how fast they erode bedrock and move sediment. The study found that the most intense glacier erosion happens in regions with large modern ice cover including Alaska, the Canadian Arctic, Greenland, Scandinavia, and the southern Andes. Areas like Central and South Asia, the Caucasus, the Middle East, and New Zealand also show some of the highest erosion rates. Led by Sophie Norris from Canada’s University of Victoria, the researchers used machine learning to combine data on glaciology, climate, and geolog...

Between 2015 and 2019 India lost 18 sq km of forest for every 1 sq km it gained, according to a new IIT Bombay study. Using high-accuracy satellite data, researchers found all states suffered net forest loss, with Tamil Nadu and West Bengal alone making up nearly half of the 1,032.89 sq km lost. While 56.3 sq km of forest cover was added, over half of it was fragmented “islets” with poor biodiversity support. Experts warn that such patchy growth can’t replace large, connected forests that sustain wildlife and prevent ecological collapse. Tigers and other species needing wide habitats face increased threats, and fragmented forests can worsen human-wildlife conflict. The team urges a shift from counting trees to planning forests with “structural connectivity” for long-term health. T...

  Thiruvananthapuram, August 11 — Kerala Chief Minister Pinarayi Vijayan on Saturday unveiled Thiruvananthapuram Corporation’s first-ever climate budget, aiming to make the capital city more sustainable and reduce its carbon footprint. This marks the first time in the state that a local body has presented a budget focused entirely on tackling climate change. Speaking at the launch at Putharikandam Maithanam, the Chief Minister said the initiative could serve as a model for other local bodies. He stressed that while climate disasters are increasing worldwide, global action remains weak, and local solutions are now crucial. “We aim to make Kerala carbon neutral by 2050, and Thiruvananthapuram’s steps are an important part of this mission,” he said. Mayor Arya Rajendran highligh...

New Delhi, August 11 — Despite receiving more than ₹13,000 crore under the National Clean Air Programme (NCAP) since 2019, Delhi has spent only 22% of the funds, leaving its battle against toxic air far from won. The capital’s air remains three times dirtier than the safe limit of 60 micrograms per cubic metre for PM10 pollution particles. In the past six years, Delhi has managed to cut PM10 levels by just 15%. By comparison, Mumbai reduced its PM10 by 44% and Kolkata by 37% over the same period. Experts say Delhi’s slow progress is worrying, especially as the city experiments with costly short-term measures like artificial rain before winter to curb smog. “Such steps show desperation, not long-term planning,” one environmentalist noted. The NCAP was launched to bring PM10 and PM2...

New Delhi, Aug 11 – A glacial lake high in the mountains above Uttarakhand’s Kheer Ganga river may hold clues to the devastating flash floods that buried Dharali village earlier this week, experts say. The National Institute of Disaster Management (NIDM) has identified the lake from satellite images taken between 2014 and 2022. The images show the water body at an altitude of around 5,200 metres, connected to Dharali via a steep mountain stream. However, scientists have not confirmed if a sudden burst of this lake, known as a Glacial Lake Outburst Flood (GLOF), directly caused the disaster. NIDM says the area is naturally prone to debris-filled flash floods because of its glaciers, loose rocks, and sharp slopes. The institute has called for on-ground surveys and hydrological studies ...

While many tropical countries are recording record-high deforestation in 2024, Indonesia has seen a slowdown in forest loss. However, nearly half of the deforestation cannot be linked to any clear cause, raising concerns over speculative land clearing, poor regulation, and hidden environmental damage. According to analysis from TheTreeMap, Indonesia lost 242,000 hectares of primary forest in 2024, a 14% drop from the previous year. Known causes such as logging, oil palm expansion, pulpwood plantations, mining, food estate projects, and fires explain less than half of this loss. The rest remains unattributed, with evidence suggesting much of the land is cleared and left unused for years. Research shows that almost half of deforested land in Indonesia stays idle for more than five year...

A new study has revealed that people’s connection to nature has fallen by more than 60% since the year 1800, raising concerns about both environmental health and human wellbeing. The research, led by Professor Miles Richardson from the University of Derby, tracked the decline using historical data on urbanisation, loss of wildlife, and the shrinking role of nature in people’s lives. The study also found a similar drop in the use of nature-related words such as “river,” “moss” and “blossom” in books between 1800 and 1990. According to Richardson, this “extinction of experience” is likely to continue unless major changes are made, such as introducing children to nature from an early age and dramatically increasing greenery in towns and cities. His modelling suggests that cities may nee...

Satellite images from the Indian Space Research Organisation (ISRO) have revealed the true scale of destruction caused by the flash flood in Dharali village, Uttarakhand. The images show a huge fan-shaped deposit of mud, rocks, and debris spread across nearly 20 hectares at the meeting point of the Kheer Gad and Bhagirathi rivers. The disaster, which struck around 1:30 pm on August 5 after intense rainfall, washed away homes, buildings, bridges, and roads. Several lives were lost, and many people remain missing. Rescue teams are still searching for survivors while trying to restore connectivity to the isolated region. According to ISRO, the debris deposit measures about 750 metres long and 450 metres wide. The satellite pictures also reveal that river channels have widened, the river...
