India Tiger Success Faces a New Challenge as States Reconsider Forest Carrying Capacity

India’s globally celebrated tiger conservation programme is entering a complex phase as rising tiger numbers begin to strain forest ecosystems and intensify human-wildlife conflict. Wildlife scientists and forest officials across tiger-rich states are now calling for a serious rethink of the concept of “carrying capacity”, a term that has long sparked discomfort among conservationists but is gaining renewed urgency. Several states with strong tiger populations, including Karnataka, have flagged the issue, arguing that while conservation measures have boosted numbers, forest landscapes themselves have not expanded. This growing imbalance is expected to be a key discussion point at the upcoming Global Big Cat Alliance summit to be held in Bandipur and Nagarhole Tiger R...

Niagara Falls Nearly Freeze as Minus-55°C Arctic Blast Grips North America

Breaking News, Climate Actions, Environment

An intense Arctic cold wave has plunged large parts of Canada into dangerously low temperatures, transforming Niagara Falls into a rare and dramatic winter spectacle. With wind chill values dropping close to minus 55 degrees Celsius, one of the world’s most powerful waterfalls now appears almost frozen in time, drawing global attention while raising serious safety concerns. The brutal cold spell has sent shockwaves across North America, with icy air spilling south into the United States. Authorities on both sides of the border have issued warnings as extreme conditions disrupt daily life, infrastructure, and tourism. Visitors arriving at Niagara Falls are met with an otherworldly scene. Thick ice coats railings, trees, and observation decks, while constant mist fr...

Why Planting More Trees May Harm Biodiversity and How New Global Standard Aims to Fix it

Environment

Tree planting has emerged as one of the most popular responses to environmental degradation. Governments announce billion-tree targets, corporations promise carbon-neutral forests, and philanthropies fund vast restoration drives. Forests are widely seen as natural solutions absorbing carbon, protecting wildlife, and sustaining livelihoods. But scientists warn that when restoration is poorly planned, it can undermine the very goals it claims to serve. As global restoration pledges have expanded, so have concerns about their ecological validity. Studies over the past decade suggest that many high-profile commitments prioritise numbers over nature, replacing complex ecosystems with simplified plantations that offer limited benefits for biodiversity or climate resilience...

DNA Study Reveals Ranthambore Tigers Feeding on Wider Prey, Livestock Emerges as Major Food Source

Environment

A new scientific study has revealed that tigers in Rajasthan’s Ranthambore Tiger Reserve are feeding on a far more diverse range of prey than previously understood, with domestic livestock now forming a substantial part of their diet. The findings raise fresh concerns about growing human–tiger conflict beyond protected forest boundaries. The study, conducted by researchers from the National Centre for Biological Sciences (NCBS) and the Nature Conservation Foundation, used advanced DNA metabarcoding techniques to analyse tiger scats collected from the reserve. The results were published after comparing this genetic method with traditional scat analysis, long considered the standard approach for studying carnivore diets. Researchers collected fresh tiger scats from ...

Global Study Warns Forest Resilience Weakening as key Tree Species Vanish

Environment

Forests across the world are undergoing a subtle but profound transformation, one that scientists warn could permanently weaken their ability to support life on Earth. A large international study has found that many forests are losing their most ecologically valuable trees and becoming increasingly dominated by fast-growing, generalist species. While these changes may appear gradual, researchers say the long-term consequences for biodiversity, climate regulation and ecosystem stability could be severe. Trees play a foundational role in sustaining life. They absorb and store carbon dioxide, stabilize soils, regulate water cycles and provide habitat for countless species of animals, fungi and insects. Forests also support human societies by supplying timber, food, shad...

Bhuj Earthquake: The Disaster That Redefined India’s Seismic Safety

Disasters, Environment

The Bhuj earthquake of January 2001 remains etched in India’s disaster history as one of the deadliest calamities since Independence. More than 13,000 people lost their lives, over 1.5 lakh were injured, and nearly a million were rendered homeless as entire towns in Gujarat collapsed within minutes. The scale of destruction exposed how unprepared modern India was for a major seismic event. Beyond the tragic human toll, Bhuj tested the entire system responsible for public safety. From urban planning and structural design to construction practices, supervision, and emergency response, every link was stressed simultaneously. What failed was not just brick, concrete, and steel, but also governance, enforcement, and the flow of technical knowledge from codes to constructi...

Snowfall Returns Late to North India, Raising Questions Over Vanishing Himalayan Winters

Disasters, Environment

Snow has finally returned to parts of North India’s higher Himalayas after a long dry spell, as western disturbances brought fresh snowfall to Uttarakhand, Himachal Pradesh and Jammu & Kashmir. While the white slopes have offered brief visual relief, scientists warn that this late-season snowfall cannot undo the damage of an unusually snowless winter, pointing instead to deeper climate shifts underway in the region. The India Meteorological Department has forecast continued rain and snowfall across the western Himalayan region till the end of the month. However, January traditionally the heart of the snow season nearly passed without significant snowfall in several high-altitude areas, including Badrinath, Kedarnath and large parts of the Garhwal region. Locals a...

River Turned Toxic: How Industrial Pollution Is Poisoning the Sirsiya From Nepal to India

Disasters, Environment

For decades, the Sirsiya river shaped everyday life in southern Nepal. Children swam in its waters, families washed clothes along its banks, and farmers relied on it for irrigation. Today, the river tells a very different story. Flowing thick and black through Nepal industrial heartland before crossing into India, the Sirsiya has become a moving channel of industrial waste and untreated sewage, threatening public health, livelihoods and cross-border relations. From lifeline to open drain in Nepal industrial capital The Sirsiya originates in the forests of Bara district and passes through the Bara Parsa industrial corridor, Nepal’s largest manufacturing zone. Once central to agriculture, religious rituals and domestic life in Bara and Parsa districts, the river now...

Drone Technology Helps Scientists Detect Early Drought Stress in Trees, Offering New Hope for Forest Protection

Environment, Idea & Innovations

Rising temperatures and frequent droughts are placing forests under increasing pressure, making it harder for trees to survive changing climate conditions. Scientists at the Swiss Federal Institute for Forest, Snow and Landscape Research have developed a new method to detect drought stress in trees using drone-based multispectral imaging, allowing them to monitor forest health from the air across large areas. During the unusually hot summer of 2023, researchers studied how seven native tree species respond to water shortages. Using drones equipped with special cameras, they were able to identify early signs of stress that are not visible to the human eye. These findings could help forestry experts better understand which tree species are more resilient to climate cha...

America Forests Are Storing More Carbon Than They Have in Decades, New Analysis Shows

Climate Actions, Environment

Forests across the United States have absorbed carbon at an unusually high rate over the past two decades, turning them into one of the country’s most significant natural allies in slowing climate change. A new scientific analysis shows that this surge is the result of a complex interaction between climate trends and human decisions about how forests are managed and conserved. Researchers from Ohio State University analysed national forest inventory data to separate carbon gains driven by natural factors from those influenced by land use and forest management. The findings suggest that U.S. forests are currently holding more carbon than at any point in recent history, but scientists caution that this trend may not continue indefinitely. Climate Conditions and Fore...
