Chris Justice is a geographer and professor at the University of Maryland whose research on land use changes and global agriculture has taken him around the world. His research has had a hand in a variety of NASA programs, including the Moderate Imaging Spectroradiometer (MODIS), Mission to Planet Earth, and the creation of the Global Inventory Modeling and Monitoring group. He talks to us about his journey into science, NASA’s relationship with agricultural research, and how NASA’s using satellite data in its Harvest Mission to tackle global food security.
