Yak faces threat of climate change
Posted on 12 Apr, 2018 11:37 AMYak--the lifeline of pastoral nomads in high altitudes of the Indian Himalayan region--is facing the threat of gradually rising temperatures in the region.

Nanomaterial from seaweed can clean toxic water
Posted on 08 Apr, 2018 09:02 PMTreatment of wastewater containing industrial dyes and toxic heavy metals is a major environmental problem as available treatment techniques are not very efficient and environment-friendly. Now a team of Indian scientists has developed a nanomaterial drawn from seaweed for effective treatment of toxic wastewater without using any chemicals.

Anthropogenic warming and climate change
Posted on 28 Mar, 2018 11:23 AMHere is more evidence why we need to worry about climate change. A new study says extreme rainfall events are on the rise in India and attributes the trend to man-made emissions, what scientists call anthropogenic warming. Not just this, the trend is likely to become more prominent by mid-century, particularly in southern and central India.

How rural women cope with climate risks
Posted on 03 Jan, 2018 04:00 PMClimate change impacts are being felt in many parts of the country, as manifested in erratic rainfall, extreme weather events and changes in cropping patterns. Adapting to these changes at farm and household levels is critical. A new study says women, particularly in marginalised communities, possess necessary knowledge to cope with climate risks.

Old is gold for Naga rice farmers
Posted on 14 Dec, 2017 10:56 AMRising temperature, erratic rainfall and occurrence of moderate drought are beginning to impact food production in Nagaland. In order to meet the challenge of climate change, the state is now turning to its forgotten resource--traditional food crops which can withstand higher temperatures and water-stressed conditions.

Climate changes Himachal farmers’ game
Posted on 30 Nov, 2017 05:48 AMWith apple production greatly affected due to changing climate in Himachal Pradesh, apple farmers are taking to cultivation of vegetables and ‘low chill’ fruits like pomegranate and kiwi.

Blame Arabian sea for unexpected showers
Posted on 05 Oct, 2017 11:19 AMEvents of heavy downpour over a short span of time have become a regular occurrence leading to frequent floods in many Indian cities, as it happened in Hyderabad this week. A new study has not only established that such events are definitely on the rise but has also found a cause for it--increasing warming of the Arabian sea.

Everyday monsoon’ foxes Mizo farmers
Posted on 21 Sep, 2017 01:52 PMAs the debate around climate change rages on with the growing intensity of hurricanes like Harvey and Irma, climate change is already becoming a ground reality for scores of farmers in the hill state of Mizoram.

Dew as a source of drinking water
Posted on 06 Sep, 2017 03:34 PMWe often notice dew drops on leaves, grass and some sloping surfaces in the morning hours. These dew drops can actually be a source of drinking water.

Small Himalayan glaciers more sensitive to climate change
Posted on 04 Sep, 2017 08:36 PMGlaciers in the Himalayas, which store large amounts of water in the form of glacial ice, have an intricate relationship with climate change. A new study in an important basin in the Indian Himalayas shows that low-altitude glaciers are more sensitive to climate change and have lost a significant amount of water in the past three decades.
