MUMBAI: The monsoon cannot come a moment too soon for Maharashtra.

Freshwater availability is changing worldwide. Here we quantify 34 trends in terrestrial water storage observed by the Gravity Recovery and Climate Experiment (GRACE) satellites during 2002–2016 and categorize their drivers as natural interannual variability, unsustainable groundwater consumption, climate change or combinations thereof. Several of these trends had been lacking thorough investigation and attribution, including massive changes in northwestern China and the Okavango Delta. Others are consistent with climate model predictions.

The NGT had earlier asked the government to act against unauthorised water extraction and directed it to seal the illegal borewells.

The city-based NGO, Siruthuli’s efforts in construction of rainwater harvesting (RWH) structures in public places across the city has helped in improving the groundwater table, says a release.

Normally groundwater recharge is estimated using methods based on water balance, water table fluctuations, fixed factor of annual rainfall and tracer movement. In many of these methods water stored in the vadose zone and evapotranspiration are not accounted properly. These factors control groundwater recharge to a large extent, particularly in arid and semi-arid regions which are normally characterized by a deep water table, thick vadose zone and high evapotranspiration.

GURUGRAM: Gurgaon has lost as many as 389 water bodies in the past 60 years, a study has revealed.
