Harvested rainwater could not only help tackle water scarcity in India but could also help people earn money, according to a recent study by scientists looking at NASA satellite data. The study is based on rainfall data collected during the Tropical Rainfall Measuring Mission (TRMM), a joint mission between NASA and the Japan Aerospace Exploration Agency, which provided observations of rainfall over the tropics and subtropics from 1997 to 2015. The study found that collecting rainwater for vegetable irrigation could "reduce water bills, increase caloric intake and even provide a second source of income for people in India".
