The guidance document provides a tool to assist the WFD (Water Framework Directive) implementation at the farm level, giving advice to national and river basin management authorities on how mandatory and voluntary measures included within the WFD Programmes of Measures can be made operational at the farm level. This guidance document was developed through a collaborative programme involving the WFD Common Implementation Strategy (CIS) partners. Ecologic Institute intensely supported the drafting of the guidance itself as well as the organisation of the CIS workshop on "Clear measures for farmers" that provided input for the guidance. The guidance document is available for download.
