InVEST is a family of tools to assess how distinct scenarios might lead to different ecosystem services and human well-being related outcomes in particular geographic areas. InVEST enables decision-makers to assess the tradeoffs associated with alternative choices and to identify areas where investment in natural capital can enhance human development and conservation in different ecosystems. InVEST models are spatially explicit, using diverse data as information input and producing maps as outputs. InVEST produces results in either biophysical terms (e.g., tons of carbon sequestered) or economic terms (e.g., net present value of that sequestered carbon). Maps, trade-off curves and balance sheets are produced, which can be used for assessing scenarios in an iterative process of stakeholder consultations.
