Résumé

A substantive volume of scientific knowledge about the interactions between forests and water is available. The relationship between water and forests depends on a number of factors such as climatic zones, time of the year, geological situation, tree species composition, forest management, etc. Forests influence the amount of water available and the timing of water delivery. Forests make a great contribution in maintaining high water quality. Forests and trees can reduce the dimension of floods and droughts and the incidence of landslides. Forests have a great potential to reduce the impacts of climate change on water resources. In arid and semi-arid conditions, the trade-offs between the water consumption by forests and trees and the environmental services they provide require a careful consideration. The importance of the relationship between water and forests is increasingly recognised, not only in the scientific world but also in policy discussions. The International Forests and Water Dialogue, which will be held on 8-9 September in the context of the XIVth World Forestry Congress in Durban, will see the official launch of a global Five-year Forests and Water Action Plan.
