    En muchas regiones del mundo, la disponibilidad y calidad del agua potable cada vez está más amenazada por su explotación excesiva, el mal uso y la contaminación. En este contexto, la relación entre los bosques y el agua debe recibir una gran prioridad. Las cuencas de captación forestales suministran una gran parte del agua destinada a satisfacer las necesidades domésticas, agrícolas, industriales y ecológicas, tanto en las zonas de río arriba como en las de río abajo.

    Dans de nombreuses régions du monde, la quantité d’eau potable et sa qualité sont menacées par la surexploitation, le mauvais usage et la pollution. Il est nécessaire à cet égard d’accorder une haute priorité aux relations entre les forêts et l’eau. Les bassins versants boisés fournissent un pourcentage important de toute l’eau utilisée à des fins domestiques, agricoles, industrielles et écologiques, dans les zones situées tant en amont qu’en aval.

    Forests, trees and woodlands cover almost one-third of the Earth’s land area. They are a crucial source of food and income for more than a billion people around the globe. They provide a variety of wood and non-wood products and vital ecosystem services – preventing erosion from wind and water, preserving water quality, shading crops and livestock, absorbing carbon which contributes to countering climate change, and providing habitat for many species of plants and animals, thus helping to conserve the planet’s biological diversity.

    Water and soils are increasingly becoming a limiting resource for meeting the food requirements
    of a growing world population. Integrated concepts for managing natural resources in a sustainable
    and environmentally sound manner show encouraging impacts, if applied on a large scale and
    over a long period like in Tigray, the northernmost regional state of Ethiopia.
