摘要：The year 2000 marked a turning point for Zimbabwe's history, particularly Land and Agrarian Reform. The study area included the dam catchment areas for Bulawayo city water supply dams in Umzingwane district, Zimbabwe. It sought to determine the appropriateness of A1 schemes in catchment areas of Bulawayo 's supply dams. Methodology involved use of primary and secondary sources. The rate of soil erosion was determined using Whitlow, (1988) benchmarks based on population changes in different land use areas. Further, the amount of soil loss on croplands was calculated based on the 43 tonnes soil lo ss per hectare benchmark (Chenje e tal., 1998). Subsequently, implications for water supply and water resources management in the watersheds were explored. Results revealed that smallholder resettlement in dam catchments of the Bulawayo city supply dams has increased siltation and reduced dam capacities. In order to achieve full benefits of the fast track land reform programme, technical support would be required to reduce environmental degradation in the watersheds
