The best way to meet this threat is by paying farmers to "grow" solar power as a remunerative cash crop. Doing so can reduce pressure on aquifers, cut the subsidy burden on electricity companies, reduce...

-The Telegraph A team of Indian engineers has designed a prototype low-cost solar-heated water desalination unit that can produce about five litres of drinking water each day and is intended for use by rural households. The desalination unit may be used to turn brackish groundwater fit for drinking at any place with abundant solar energy, the team of engineers, who are from the National Institute of Technology in Kurukshetra and an engineering...

-The Hindu THIRUVANANTHAPURAM: Much of the drop in yield came from air pollution caused by fine particles like soot as well as ozone generated by sunlight acting on emissions of precursor molecules. India's food grain production is facing a double whammy, with heightened air pollution adding to the impact of climate change on crop yields, according to a recent study. "Our statistical model suggests that, averaged over India, yields in 2010 were up...
