Feeding a growing global population is a major concern, but efforts to grow more food will place an added burden on precious supplies of freshwater. New research shows how measurements of soil moisture from space could be used to understand how much water is used for agriculture and potentially help farmers manage consumption.
A new approach for quantifying irrigation by using soil-moisture observations from satellites such as ESA’s Soil Moisture and Ocean Salinity (SMOS) mission is being explored via the WACMOS Irrigation project.
