The United Nations University project Climatic, Biotic, and Human Interactions in the Humid Tropics was initiated as part of the University's programme on Resource Policy and Management to investigate the interactions between forest cover and critical climatological and biogeochemical parameters in the humid tropics. Considering the abundance of speculation and anxiety with regard to the impact of human activity on the earth's climate and biosphere, the need was strongly felt for more scientific information on biotic and climatic interactions to more accurately determine the actual nature and extent of human inflicted damage to environmental systems.

The present study arose from a workshop whose aim was to evaluate existing evidence of the ecological impact of deforestation and afforestation on regional climate and hydrology. This volume makes a clear case for the need for an objective and quantitative assessment of the effects of vegetation on climate and hydrology and their regional extent.
