Farm ponds change farmers’ fortunes
While farm ponds in Jharkhand have helped farmers increase yields, they have also exposed them to the risk of price fluctuations, highlighting the need for ‘beyond the farm’ interventions. Posted on 13 Sep, 2019 01:09 PM

While enhanced irrigation coverage has been hailed as an important way to improve agricultural productivity, it continues to lag behind in India and agriculture continues to be rainfed, subject to the vagaries of the monsoon.

Aerosols increase drought severity over the Indian subcontinent
Study finds aerosols - suspended fine solid or liquid matter in the atmosphere - are adding to El Nino, which already deters the Indian monsoon. Posted on 10 Sep, 2019 12:24 PM

Pune, September 05 (India Science Wire): A team of atmospheric scientists from India, USA and Canada have found that aerosols in the atmosphere can increase the severity of droughts over the Indian subcontinent by as much as 17 per cent during El Nino years.

Experts say cold desert regions need special attention
Desertification at high altitudes increasing due to melting of glaciers, causing concern and a push to devise preventive adapation strategies. Posted on 06 Sep, 2019 10:38 AM

Greater Noida, September 5 (India Science Wire): Degradation of land, which leads to the process of desertification, is not limited to arid and semi-arid areas but is also visible in high altitude regions that get very little rainfall and are known as cold deserts.

Vanishing water bodies behind Ahmedabad’s warm climate
A study shows how the open space on the western bank of the Sabarmati river in Ahmedabad acts as a heat sink. Posted on 28 Aug, 2019 10:48 AM

A study published in the Journal of Remote Sensing and Space Sciences, analyzing the cooling effect of the city of Ahmedabad’s water bodies, has thrown up some interesting findings. The east bank of the Sabarmati river, which flows through Ahmedabad, was found to be significantly cooler than the west bank, witnessing a greater drop in temperature even during summer.

Beyond the death toll: The everyday violence of Assam’s floods
Mitul Baruah from Ashoka University narrates personal experiences of people affected by floods in Majuli, Assam. Posted on 19 Aug, 2019 12:53 PM

Floods are an annual phenomenon in Assam. They are as integral to the state as the Brahmaputra River is, and each monsoon, we are reminded that Assam exists (or is drowning). As I write this piece, Assam is slowly recovering from the first wave of flood this monsoon.

Mangroves: Powerhouses of carbon storage the planet desperately needs
Mangroves are carbon-dense ecosystems that can play an important role in carbon storage, study suggests. Posted on 16 Aug, 2019 09:35 AM

Straddling land and sea and swarming with life, mangroves are key to healthy coastal ecosystems. They are recognised for their role as storm barriers, protecting coastal areas from flooding and erosion by dissipating the energy of huge waves. They act as nurseries for fish, help filter river water of pollutants and trap excess sediment before it reaches the ocean.
