Biodiversity

Ecosystems rarely collapse without warning. Long before forests decline, lakes become polluted or coral reefs disappear, nature often shows subtle signs that its resilience is weakening. Today, scientists are using satellite observations,…

A lake turning bright green may appear harmless, but it often signals a growing environmental crisis. Triggered by excessive nutrients, warming temperatures and pollution, harmful algal blooms are becoming increasingly common in freshwater…

Hidden inside seed banks are millions of tiny time capsules containing the genetic diversity that future agriculture may depend upon. As climate change, biodiversity loss and emerging crop diseases threaten global food security, these…

Freshwater is one of Earth's most limited yet essential resources, sustaining people, agriculture, industry and ecosystems alike. As climate change alters rainfall patterns, glaciers retreat, groundwater declines and pollution contaminates…

Every animal leaves behind tiny traces of its DNA in water, soil and even the air. Scientists are now using this invisible genetic fingerprint—known as environmental DNA (eDNA)—to monitor wildlife without disturbing it. From detecting…

Modern conservation is no longer limited to field surveys and camera traps. Today, satellites orbiting hundreds of kilometres above the Earth are helping scientists monitor forests, track wildlife, map wetlands and detect environmental…

Tree plantation drives have become a symbol of environmental action across India, with millions of saplings planted every year. But does planting more trees necessarily mean creating more forests? Scientists say the answer is far more…

India's forests may still stand, but the natural pathways connecting them are disappearing. Wildlife corridors—essential routes that allow elephants, tigers and countless other species to move safely between habitats—are increasingly being…

Wildlife conservation is often associated with iconic animals like tigers and elephants, but biodiversity extends far beyond these familiar faces. Every day, bees pollinate crops, earthworms enrich the soil, frogs control insect…

Across Odisha, the arrival of the monsoon has long marked the beginning of a new agricultural season. But in recent years, changing rainfall patterns have raised concerns about an increasingly uncertain future. While large-scale climate…
