Can forests "provide" water: widespread myth or scientific reality?

The article presents two contrasting views of deforestation and groundwater recharge/dry season flow. Seven variables causing the dichotomy are identified and analyzed. These include the comparative importance of various hydrological processes, research methodological aspects, people's perception of change, and unclear definitions. A simple model indicating the most likely catchment response to deforestation is presented. Recharge through macropores is argued to be the key mechanism for conveying rainwater to groundwater in the dry tropics. Management aspects of forests and water are discussed.
