Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST)
Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) is a suite of software models that can be used to map and value the different services provided from the natural environment, many of which are vital for social and economic wellbeing. InVEST is a tool that enables decision-makers to assess and quantify the trade-offs associated with alternative management options and determine where investment in the natural environment can enhance both human development and the conservation of the environment. The tool can be used to estimate how the current location, amount, delivery, and value of relevant ecosystem services are likely to change in the future within user-defined scenarios. It produces detailed maps and results that describe the biophysical or economic impacts of different management choices. The toolset currently includes sixteen distinct InVEST models suited to terrestrial, freshwater, and marine ecosystems.
