In this collection of case studies we have attempted to create a showcase of the tools, approaches, best practice guidance and projects currently being delivered by organisations, groups and individuals engaged in Defra’s Catchment Based Approach Initiative. It is hoped that this collection will continue to grow as further case studies are contributed and all of the material presented here will also be placed onto the Catchment Based Approach website. This document has been produced through a collaboration between the Westcountry Rivers Trust, The Rivers Trust and the Catchment Based Approach Community and with funding from the EU LIFE Programme as part of the WaterLIFE Project. WaterLIFE aims to help local communities engage with River Basin Management Plans and to deliver on-the-ground improvements that support accelerated delivery of the Water Framework Directive.
