River basins not climate resilient
River basins remain highly vulnerable to climate change, a new study finds out. arathi posted 3 years 3 months ago

Climate change remains a matter of concern globally. A new study by Indian researchers has shown that only six out of 22 river basins in the country have the potential to cope with the threat of climate change, particularly droughts.

Wastewater from tanneries makes farm soil toxic
Wastewater from tannery industries that reach agricultural lands ruin soil health and pollute groundwater, a study finds out. arathi posted 3 years 7 months ago

The use of wastewater for irrigation in agricultural lands is a common practice across the globe. But a study by Indian researchers has found that it can also affect the quality of soil and groundwater, and consequently, human health. 

Greywater irrigation more profitable
A study that finds many trees like eucalyptus grow better with greywater than ground water shows a better way to manage water. arathi posted 3 years 8 months ago

Over the years, the increasing population and urbanisation have meant growing shortage of land for disposal of domestic greywater, indiscriminate cutting down of forests for biomass production and lesser availability of water for irrigation.
