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.

To reduce risks from natural disasters and build climate resilience, decision makers are using NASA Earth observations to develop index-based insurance products and protect low-income customers in Central America, especially in the region known as the Dry Corridor.
GPM Earth Day 2020 Banner
On April 22, 2020, people around the world will celebrate the 50th anniversary of Earth Day, embracing our commitment towards understanding the planet’s environmental processes and protecting it for future generations. In support of this global event, NASA is highlighting the agency’s contributions to the environment with a week of online events, stories, and resources.

Download this video from the NASA Goddard Scientific Visualization Studio Today, India is among the world’s most water-scarce countries. This means that it does not have enough freshwater resources to meet the needs of all the people who live there. Mismanagement of water resources have largely contributed to the country’s limited water supplies. A growing competition over finite water resources will have serious implications for Indian farmers, as well as India’s food security. More than 70% of India’s population rely on agriculture as a source of livelihood. Even more so, an estimated 82% of...
IMERG rainfall totals from Australia in November 2019
Droughts and dry, arid conditions are naturally occurring phenomena in Australia. Such an environment is conducive to wild fires, which are started mainly by lightning and can occur throughout the year, but typically emerge between October and April and are most prevalent during the Southern Hemisphere summer; they are part of the seasonal cycle in Australia. However, some years are worse than others, and the 2019-2020 wild fire season was especially bad. It has been estimated that upwards of 46 million acres were burned, or roughly the size of the entire state of Washington. In terms of area...
IMERG Sees a Dry September
Rainfall was scarce across much of the country in the month of September, pushing the eastern and southern thirds of the country into drought conditions. IMERG, the Integrated Multi-satellitE Retrievals for GPM, is a unified satellite precipitation product produced by NASA to estimate surface precipitation over most of the globe.
Using the IMERG Long-term Precipitation Data for Applications
A long precipitation data set like the new GPM IMERG V06 product is valuable for many applications and for decision-making. Accurate and reliable precipitation records are not only crucial to understanding trends and variability but also for water management resources and food security, ecological management, and weather, climate and hydrological forecasting. Here we present a few highlights showcasing how GPM IMERG is helping a variety of end users make decisions that will benefit society for years to come.
