Impact/Purpose:
The Narragansett-3VS model uses system dynamics to explore scenarios for Nitrogen reduction in the Narragansett Bay Estuary and Watershed under selected potential policy options. This information sheet provides an overview of the model to potential users.
Description:
In an effort to advance sustainability, EPA Region 1 (New England) and the EPA Office of Research and Development (ORD) are collaborating on a project to address the problem of nutrient impairment to ecological functions in sensitive waterways. The project is based on the Triple Value (3V) framework, an innovative approach that captures the dynamic interrelationships among economic, environmental, and social systems. This approach is being piloted in the Narragansett Bay watershed with the development of a policy simulation tool that draws from watershed-specific data and stakeholder input. The model, entitled Narragansett-3VS (Triple Value Simulation) enables users to explore different scenarios, interpret results and evaluate outcomes of selected policies or interventions aimed at reducing adverse impacts of nutrients on the watershed. The model is based on an integrated assessment methodology called System Dynamics and is intended to serve as a communication tool that can help build shared understanding of policy alternatives among diverse groups including technical experts, policy makers, and citizens. This Information sheet briefly describes the structure and content of the Narragansett-3VS model and serves as an introduction to the key components of the full model and its documentation.
