Groundwater depletion alarming in northwest, central India

While a majority of districts in India experienced significant depletion in groundwater storage, those in the Indo-Gangetic plain, northwestern, central, and western parts of India showed the most reduction due to intensive groundwater-based irrigation. Irrigation based on information provided by tensiometers helped farmers in five districts of Punjab save up to 36% groundwater. With 230 … Continue reading Groundwater depletion alarming in northwest, central India

Decline in low-intensity rainfall reduces groundwater recharge in north India

Research carried out by IIT Gandhinagar team has found increased groundwater recharge in south India between 1996 and 2016 due to increase in high-intensity rainfall during monsoon. But in the case of north India, the decline in low-intensity rainfall during the same period has resulted in a reduction in groundwater recharge. Based on data collected … Continue reading Decline in low-intensity rainfall reduces groundwater recharge in north India

IIT Gandhinagar: Changing rainfall pattern results in groundwater deficit in north India

The groundwater level in north India declined at a rate of 2 cm per year during the period 2002-2013, while in north-central and south India it increased by 1-2 cm per year during the same period, says a study carried out by a team of researchers from the Indian Institute of Technology (IIT) Gandhinagar. While … Continue reading IIT Gandhinagar: Changing rainfall pattern results in groundwater deficit in north India

IIT Gandhinagar develops irrigation maps of India

The irrigation maps from 2000 to 2015 for the entire country are available in a repository and can be freely accessed by researchers and others. The repository will be updated every year. For the first time, high-resolution maps of irrigated areas across India from 2000-2015 have been prepared using remote sensing data. The maps were validated … Continue reading IIT Gandhinagar develops irrigation maps of India

IIT Madras researchers prove the superiority of arsenic water filter which got $18 million funding

An exhaustive research carried out by a team of researchers led by Prof. T. Pradeep from the Department of Chemistry at the Indian Institute of Technology (IIT) Madras, spread over four years has put to rest the scepticism about the merits of the arsenic water filter developed by them. The water filter has been in … Continue reading IIT Madras researchers prove the superiority of arsenic water filter which got $18 million funding

60 percent of Indo-Gangetic groundwater too contaminated to use

The water table has either been stable or rising between 2000 and 2012 across 70 per cent of the aquifer in the Indo-Gangetic Basin that is spread over more than 250 million hectres across India, Bangladesh and Pakistan. In the remaining 30 per cent of the aquifer, ground water levels are falling, amounting to a … Continue reading 60 percent of Indo-Gangetic groundwater too contaminated to use
