• Key Words: desertification, desertification risk map
• About the Map: The Risk of Human-Induced Desertification is based on an overlay of the global desertification map and a global population density map.
• Possible Uses of the Map: Useful for teachers and students who are interested in the global distribution of human-induced desertification. Global modelers may be able to use the data for small scale analysis.
