This document presents an overview of know-how related to the impact of the forest and its management on water resources. The first part is primarily focused on water demand and the effects of the forest on water resources, as well as practices and the legal framework that would make the combined management of forests and water resources possible. The second part presents more detailed information on specific themes, in the form of ten technical data sheets (for example, "Forest and water resources", "Forest and water quality", "Riverains", etc.). Recommendations are given for the purpose of providing integrated management solutions for the forest and water resources.
