Prized Science | Every drop counts, and making quality medicine
Vimal Mishra, Vikram Sarabhai Professor of civil engineering at IIT Gandhinagar, has won this year’s Shanti Swarup Bhatnagar Prize for Earth, Atmosphere, Ocean and Planetary Science. He discusses his work, which quantifies how water resources have been affected by climate change and human activities, and the relative contribution of these two factors. Our research has demonstrated that while climate change has affected the rainfall characteristics that resulted in reduced groundwater recharge, groundwater pumping for irrigation caused a rapid groundwater decline in north India. We have developed an integrated framework that combines in-situ and satellite-based observations and hydrological modelling to estimate the relative contribution of climate and human interventions on water resources and hydrological extremes. Over the last several years, the water and climate lab at IIT Gandhinagar has not only quantified the impacts of climate change and human interventions on water resources and hydrological extremes, but also developed an operational monitoring and forecasting system in collaboration with other agencies.
