Environmental Indicators

Environmental indicators offer a simple measure of the status of an environmental attribute.

  Many different specific environmental indicators are available, examples include indicators of potential damage, such as toxic emissions, as well as indicators of potential benefits, such as biodiversity. Environmental indicators can be used in trade-off analysis.  Below are links to useful general indicators as well as links to soil erosion, pesticide toxicity, and other indicators.

General Indicators:

Soil Erosion Indicators:

Tools for estimating the effects of water-caused soil erosion range from a single equation to a complex simulation model. Three major tools are:

  • Universal Soil Loss Equation (USLE):  This is the original and most widely used tool for estimating soil erosion without knowing location specific data, developed by Ontario’s Ministry of Agriculture, Food, and Rural Affairs.
  • Revised Universal Soil Loss Equation (RUSLE):  RUSLE is a revised, updated version of the USLE, developed by the U.S. Dept. of Agriculture.
  • Water Erosion Prediction Project (WEPP):  WEPP is a process-based, distributed parameter, continuous simulation, erosion prediction model. It can simulate hill slope erosion processes, as well as simulation of the hydrologic and erosion processes on small watersheds.
