520			_aBenchmark estimates of soil loss in Rwanda were made to examine some of the principal environmental conditions and conservation practices that contribute tosoil erosion. Soil loss was estimated by using the universal soil loss from field data collected on more than 19,000 fields. Seasonal soil losses ranged from 1 t/ha to 143 t/ha; the average seasonal soil loss was 5 t/ha. Soil loss in Rwanda showed a pattern of regional differences that closely followed variationsin rainfall and topography. The development of regional strategies to minimize agricultural erosion is likely to be more effective than a single national policy, even in a country as small
