One of the biggest changes in world agriculture is less than the food itself, like the water we use to grow it. In some areas, farmers use freshwater resources, including groundwater, at an alarming rate. The GRACE satellites allow scientists to detect changes in aquifers by monitoring changes in Earth's gravity. In northern India, farmers rely heavily on irrigation to grow crops, and the resulting depletion of the huge aquifer creates an uncertain future in the region.
