Dams, in distress?
It is time water policies in India acknowledge that many large dams have aged and can no longer be looked upon as the only path to water security. aartikelkar posted 1 year 6 months ago

India is reeling from a severe water crisis. Large parts of the country are experiencing water-stress worsened by the ever increasing demand for water due to population growth, rapid urbanisation, changing lifestyles and consumption patterns, inef?cient use of water and climate change.

Drinking water programs in India treat urban and rural areas separately, generally neglecting the special characteristics of settlements referred to as peri-urban – those on the outskirts or peripheries of urban areas, or “rurban” settlements i.e. rural areas with urban facilities.

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. Amita Bhaduri posted 1 year 6 months ago

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.

Hydropower in the Himalayas: Potential and risks
Study highlights significant hydropower opportunities in the Hindu Kush Himalayan region. Amita Bhaduri posted 1 year 6 months ago

Worldwide, the demand for energy has risen significantly and quickly, leading to serious impacts on environmental sustainability and hindering global efforts to mitigate climate change. Hydropower, a leading renewable option has the additional benefits of water storage for agriculture and other uses.

Growing crops, one byte at a time
Mobile agri-advisory services provide timely and relevant advice to farmers. But do they translate to practice in the field? Amita Bhaduri posted 1 year 6 months ago

Agricultural extension and advisory services facilitate the transfer of knowledge, information, improved technologies and practices to farmers, farmer organizations and market actors. Research has shown positive effects of extension access when it came to knowledge, adoption, productivity, and economic returns for farmers.

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. Amita Bhaduri posted 1 year 6 months ago

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.
