  • Key Words: land quality, human impacts
  • About the Map: The Anthropic System Tension Zones map is based on an overlay of the global land quality map and a global population density map. Biodiversity hotspots are also outlined.
  • Possible Uses of the Map: Useful for teachers and students who are interested in the global distribution of anthropic tension zones. Global modelers may be able to use the data for small scale analysis.
