Recent research has found that if nothing is done to counter the effects of global warming, by the year 2080, half of the common plants on earth and one third of animals will lose their climate range. This means that the ecosystem, or the habitat of the animal or plant, will be lost and will…
Guards in Assam’s protected forests have to face poachers armed with sophisticated guns day in and day out. Waking up to the serious lacuna in the system, conservation authorities in Assam and local NGOs have recently introduced technology such as conservation drones in Kaziranga.

The government’s move to demarcate eco-sensitive zones around protected reserves is a timely move. But, wildlife corridors too need equal attention. Every animal, from a hare to an elephant, and a snow leopard to a butterfly, needs the forest in its entirety and cannot survive in fractured fragments. Development has to be woven around wildlife,…
Atula Gupta narrates the story of exploitation of the mangrove forests that border West Bengal and Bangladesh, and also suggests a few measures to save the mangroves. The mangrove forests in Sunderbans consist of 54 tiny islands, criss-crossed by innumerable tributaries of the Ganges that were once infested by Arakanese and Portuguese pirates. But today,…
A study has shown that the body size of marine species is disproportionately affected by warmer temperatures. According to researchers, the most likely cause of the drastic shrinking size of marine animals is due to the much lower availability of oxygen in water than in air. Warming increases the need for oxygen across species, but…
Centuries-old trees provide nesting and shelter for up to 30 per cent of all birds and animals in some ecosystems. They store huge amounts of carbon, recycle soil nutrients, create rich patches for other life to thrive, and influence the flow of water within landscapes. In India, the banyan and the peepul are still plentiful,…
