We created an interactive, expandable tree diagram of PEWI’s science model for users to explore the components of all seven science modules. By navigating to the science model webpage, you can click on any node to expand the model out to increasing levels of detail. For example, the nitrate-nitrogen concentration module contains four subcomponents:conservation practices, row crop area, precipitation, and strategic wetlands. Clicking on any of these subcomponents expands the model out even further! We encourage you to play with the interactive diagram to learn more about how PEWI links land use, climate, and ecosystem services.
