The forests cover approximately the quarter of the surface of the continents. They on average consume more water than the meadows and the cultures, because of a foliar index and a high roughness which contribute to the interception of the rains and perspiration ; a deep rooting makes it possible to maintain this perspiration for limited periods of dryness. The global changes will have on the forests the positive and negative effects whose assessment is still uncertain.
