      Biospheric Aspects of the Hydrological Cycle (BAHC) was established as one of core projects of the International Geosphere Biosphere Programme (IGBP) in 1992. Its main focus is to study the role of the terrestrial biosphere in the hydrological cycle. BAHC is an interdisciplinary project combining and integrating expertise from several disciplines, including eco-physiology, biogeochemistry, hydrology and meteorology.The Global Energy and Water Experiment GEWEX was initiated in 1988 by the World Climate Research Programme (WCRP) to observe and model the hydrologic cycle and energy fluxes in the atmosphere, and at the land and ocean surface. GEWEX is an integrated program of research, observations, and science activities ultimately leading to the prediction of global and regional climate change. In this report, we present a brief overview of the synthesis research highlights of both international programmes with the primary focus on the biospheric feedbacks in the hydrological cycle and on interactions with the climate system. A full extended research synthesis book, to production of which this NOP project contributed, is currently in press by Springer Verlag (Kabat et al (eds), 2002: Vegetation, Water, Humans and the Climate: A New Perspective of an Interactive System, 650 pp; ISBN 3-540-42400-8)
