Abstract

Watersheds are an attractive unit for development in mountainous landscapes. However, watershed analysis usually requires significantly more time, data and funds, and must include more actors, Also, results may be disappointing, Many off-site effects are very difficult to modify without major changes in land use systems, Frequently, these land use changes (eg more pastureor reforestation) pit soil conservation against rural employment. In othercases, sediment may not be originating on-farm, but primarily in other parts of the landscape, implying civil engineering rather than on-farm solutions. On the other hand, we have found that good maps and valid models are ofgrowing interest to municipal authorities as they consider alternative development plans.
