Abstract: Perceived hydrological benefits of tropical reforestation programmes have come under severe scrutiny in recent years with "public" and "scientific" views differing widely. Some would argue that the "scientific" perception tends to overemphasise the high water use of trees while downplaying or even ignoring such positive aspects of forestation as enhanced infiltration and soil protection. In this talk the state of play will be presented with regard to the impacts of reforesting (degraded) tropical land in terms of changes in annual and seasonal water yield based on examples from the literature and ongoing work by the Amsterdam Critical Zone Hydrology Group.
About the speaker: Sampurno Bruijnzeel is a professor of Land Use and Hydrology with 38 years of experience with forest hydrological research in the humid tropics of South-east Asia and the Pacific, the Caribbean, and Central America. His main research interests include the hydrological functioning of tropical montane cloud forests, plantation hydrology, erosion and sedimentation, and ecosystem productivity and nutrient cycling issues. He heads the Amsterdam Critical zone Hydrology Group and the Amsterdam Centre for RESearch on Restoration, Reforestation and Regreening (ACRES_R3) - a recently erected platform for the generation and exchange of knowledge to promote the regreening of degraded land worldwide. In 2005 he received the Busk Medal of the Royal Geographical Society of the U.K. for his contributions to biosphere research in the humid tropics.
