SWAT (Soil and Water Assessment Tool) is the most widely applied hydrology (and associated catchment processes) model worldwide. There are current efforts getting under way to develop protocols for assessing Ecosystem Services using SWAT, but there is little consensus and no clear guidelines for new or veteran researchers in using SWAT for this purpose. Because of the models’ widespread use, it is important that standard protocols and guidelines be developed to support CG research in their efforts. The project will aim to: 1. Produce User Guidelines for employing SWAT to assess ecosystem services. Guidelines will be published as a WLE Publication and linked to the recent WLE ESS&R Framework 2. Facilitate and strengthen the CG SWAT Community of Practice, initiated in 2014, holding a meeting during 2015. 3. Continue work to develop socio-hydrological approaches to integrating gender differentiated assessment of ecosystem services using SWAT by finalizing methods paper.
