Satellites can reveal how many fields have been planted and how a crop is growing, providing a way to predict how much of a give commodity will be available at harvest. Governments and aid agencies around the world use this information to help them make informed decisions about food prices and trade and the possible need for aid long before harvest. The organizations that use NASA data include the United States Department of Agricultures Foreign Agricultural Service and USAID's Famine Early Warning System Network.
