dc.description.abstractAlbedo is an important part of the radiation regime of any surface as it indicates the relative amount of solar radiation retained by the surface. Variations in albedo of the earth's land surface are broad. Bare, moist dark soils reflect as little as 9%, grasslands 26% and sandy deserts 37%. Man alters the natural environment in many ways, one of which is through altering the natural albedos. The primary aim of this project is to determine the actual variation in albedos amongst some South western Cape natural and disturbed veld types. Disturbances such as overgrazing, crop-development and fire are included. Surface readings were taken during January and June in ten veld types and floristic and soil data as well as climatic variables were measured. Disturbed veld types were found to have significantly higher albedos than natural veld types. The net loss of radiation may have significant climatic implications, which are discussed.en_ZA
