IIT Bombay researchers have found the reason why the summer monsoon rainfall has shifted towards northwest India and intensification of extreme rainfall is seen over central India during the month of September. They have developed a land-surface model that takes into account the Indian conditions. For the first time, researchers from the Indian Institute of … Continue reading Irrigation, agriculture shift rainfall to northwest India, IIT Bombay finds

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 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
