The Human Influence Index (HII) is a measure showing direct human influence on ecosystems using 8 measures of human presence.

Measures used

The eight measures used in computing the HII are:

  • Population Density/km2
  • Score of Railroads
  • Score of Major Roads
  • Score of Navigable Rivers
  • Score of Coastlines
  • Score of Nighttime Stable Lights Values
  • Urban Polygons
  • Land Cover Categories (urban areas, irrigated agriculture, rain-fed agriculture, other cover types including forests, tundra, and deserts)

    • HII values range from 0 to 64. Zero value represents no human influence and 64 represents maximum human influence possible using all 8 measures of human presence
