O uso de água pelas plantações florestais - Uma revisão

Abstract

This review aims to present some of the main results and infer about the current state-of-the-art of the controversy related to the water use by forest plantations. Several studies have been carried out in this area in different regions, mainly in Australia, South Africa, Europe, India and Brazil. However, according to authors, the controversy persists and it is necessary that the scientific results are understood by the community in order to avoid the predominance of myths and half-truths. In this way, the current review intends to summarize some scientific results concerning the main hydrologic aspects of the plantations (interception, transpiration and catchment water balance), the relationship between the high productivity and the water use efficiency, and the importance of the establishment of forest management plan focused on the river watershed scale, in order to contribute to hydrological sustainability. The results coincide that the relationship between the forest plantations and the water depends on the region, species, environmental conditions and management practices on the watershed scale.
