As the climate of our home planet changes, some places are drying out and others are getting wetter, including the land that produces the food we eat. Farmers are learning how to adapt to changing climate conditions. @NASA’s fleet of satellites has been watching over Earth for more than half a century, collecting valuable data about the crops that make up our food supply and the water it takes to grow them. This wealth of information allows scientists to monitor farmland – tracking the overall f
