The Resource Investment Optimization System (RIOS) is no longer supported by the Natural Capital Project, meaning we are unable to provide an installer for download. Nor can we provide bug fixes or user support. If you are interested in using the source code, or are looking for the User Guide or sample data, you can find it here. RIOS supports the design of cost-effective investments in watershed services.

RIOS was created to provide a standardized, science-based approach to watershed management in contexts throughout the world. It combines biophysical, social, and economic data to help users identify the best locations for protection and restoration activities to maximize the ecological return on investment, within the bounds of what is socially and politically feasible.
