 Abstract

Land management in upper watersheds involves some interactions among land and water resources, manpower, technology, economics and social aspects. Land use dynamics in the upstream have logical consequences on changing spatial configuration and diversity of land requirements, which lead to spatially-varying land quality. Evaluation of land utilization should be taken into account to control land use conversion, which is naturally arduous to predict, especially in Indonesia. National policy on spatial planning requires special, implementable approaches, preferably spatial-based.  Monitoring scheme, regular  recording and field validation were primary consideration in this research, driven by physical aspects and understanding of limiting factors to land utilization. The research   assessed spatial valuation based on three scenarios: (i) suitability of land utilization using land suitability approach; (ii) suitability of land utilization according to spatial planning; and (iii) suitability of spatial planning in association with land capability. Those three scenarios provided optimum configuration of lands and an aid to assess deviance to current spatial planning.
