Forest and water managers are facing a great challenge maximizing a wide range of multisectoral forest benefits without detriment to water resources and ecosystem function. A better understanding of the interactions between forests/trees and water is needed to address this problem. This is for the awareness raising and capacity building in forest hydrology, and for embedding this knowledge and the research findings in policies. Recent forest hydrology has focused on the comparative advantages and disadvantage of forest cover in maximizing downstream water yield; the role of upstream forests in maintaining water flows during the dry season; and water quality preservation. Following the International Year of Freshwater 2003, forest hydrologists, water sector experts and policy-makers has focused on three core issues: incorporation of forest hydrology knowledge in water policies, inclusion of forest-sector contributions in integrated water resource management policies; and payment for forest- and water-related environmental services. After the five years since the Shiga Declaration, the Third World Water forum and the International Year of Freshwater, modern scientific understanding of forest and water interactions has been continuously spreading international and national environmental policies. New perspectives on water and forest interactions have enabled a clearer understanding of what forest can do to deal with the challenges the world will increasingly face in terms of the availability, quality and management of water resources.
