This Master thesis report has been realised in the context of the Interreg project “Alpeau” between France and Switzerland. Alpeau aims to sustain the protective functions of forest towards drinking water resources and to establish amicable contracts between local authorities responsible for water supply and forest actors. Cases all over the world where particular forest management has been implemented to protect drinking water resources have been inventoried. The forest management measures applied at these sites and the way they are implemented (land acquisition, regulation, contract) are studied. Broad forest management principles could be highlighted. These rules are then transposed to French and Swiss sites of Alpeau project. Forest management recommendations are made and propositions of contracts establishment are suggested.
