Water and Agriculture

Growing human population, increased demand for water and energy, and a changing climate have contributed to expanded concerns centered on freshwater resources and food supply and production. Both water resource managers and the agricultural community need to know the amount and distribution of seasonal rainfall and the timing of the onset of rainfall to prepare for freshwater shortages and forecast crop yields. Remotely sensed precipitation estimates play a key role in predicting changes in freshwater supply and agricultural forecasting. The Water Resources, Agricultural Forecasting, and Food Security Applications area promotes the use of precipitation data from the GPM constellation to analyze and forecast changes that affect water resources and its subsequent impact on agricultural productivity.

A Tale of Two Extremes: Rainfall Across the US
The United States has seen a tale of two extremes this year, with drenching rains in the eastern half of the country and persistent drought in the west. A new visualization of rainfall data collected from space shows the stark contrast between east and west for the first half of 2015. The accumulated precipitation product visualized here begins on Jan. 1, 2015, and runs through July 16, 2015. This visualization shows the heavy rainfall throughout Northern Texas and across Oklahoma as well as the drought in Southern California.

Using NASA Data to Show How Raindrops Could Save Rupees
Rainwater could save people in India a bucket of money, according to a new study by scientists looking at NASA satellite data. The study, partially funded by NASA’s Precipitation Measurement Missions, 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. The study, published in the June issue of Urban Water Journal, is based on precipitation data from the Tropical Rainfall Measuring Mission (TRMM), a joint mission between NASA and the Japan Aerospace Exploration Agency, which...
