Integrated Valuation of Ecosystem Services and Trade-offs (InVEST)

Purpose

The Integrated Valuation of Ecosystem Services and Trade-offs (InVEST) tool is a suite of free open source software models for the mapping and valuing of ecosystem services throughout terrestrial, freshwater and marine ecosystems. It enables decision makers to assess quantified trade-offs associated with alternative management choices and to identify areas where investment in natural capital can enhance human development and conservation.

Description

InVEST is the main tool developed by the natural capital project in partnership with several academic collaborators including Stanford Department of Biology, the Chinese Academy of Sciences & The Nature Conservancy. The multi-service, modular design of InVEST provides an effective tool for balancing the environmental and economic goals of many stakeholders when ecosystem services are to be considered.    The toolset includes eighteen distinct ecosystem service models designed for terrestrial, freshwater, marine, and coastal ecosystems;

  • Habitat quality
  • Habitat risk assessment
  • Pollinator Abundance: Crop Pollination
  • Forest Carbon Edge Effect Model
  • Carbon Storage and Sequestration: Climate Regulation
  • Coastal Blue Carbon
  • Water Yield: Reservoir Hydropower Production
  • Nutrient Delivery Ratio Model
  • Sediment Delivery Ratio Model
  • Unobstructed Views: Scenic Quality Preservation
  • Visitation: Recreation & Tourism
  • Wave Energy Production
  • Offshore Wind Energy Production
  • Marine Finfish Aquacultural Production
  • Fisheries
  • Crop Production
  • Seasonal Water Yield Model

 

The software was originally developed as an ArcGIS add on in the ArcToolBox environment but all models are currently available as standalone software that is freely accessible through the developer’s website.

Running InVEST effectively does require knowledge of python programming however software such as QGIS or ArcGIS will be required to view results. The sub-models use input data (map/GIS data and information in tables) to explore how changes in ecosystems are likely to effect the flow of benefits provided to human features. Analysis can occur throughout a range of spatial resolutions ranging from local to regional and even global.
