Keeping Track of Food Production From Space
While USDA has monitored crops around the world for almost a century, the discovery that satellites can “see” greening of vegetation has revolutionized agricultural monitoring for food security. The development of the GLAM system in the 1980s, a collaboration with USDA and the International Production Assessment Division, has helped governments to assess whether or not there will be enough basic food crops to feed their populations, as well as provide international food aid organizations with a tool to predict where food shortages might occur.

![The U.S. Department of Agriculture tracks how many acres and the annual yield for every crop produced. One method used to estimate crop acreage and yield is remote-sensing data from the NASA-USGS Landsat satellite program. The program started in 1997,with North Dakota, and by 2008 covered the entire lower 48 states and the District of Columbia.
