AbstractGiven the long, narrow river valleys flanked by lofty ridges, with heterogeneous spatial, physical and socio-economic features, rational watershed management in t he middle Hills of Nepal must be based on the systematic analysis of relationships among spatial , physical and socioeconomic phenomena. Planning for environmentally suitable and economically sustainable watershed development requires a multipronged strategy, with foci on all aviating the otherwise ever increasing pressure on forest and arable land resources and on eradicating abysmal poverty. In doing the groundwork for such planning strategy, cross-sectional as well as longitudinal research was undertaken in the Upper Pokhara Valley, covering four ridge and valley settlements each represented by 298 farm households of different landholding categories and castes, with emphasis on their resource use and management systems. Factors determining resource management were tested. To complement the inventory of existing conditions, spatial and temporal processes of l and use changes since 1957 were investigated, using topographical and land utilization maps, aerial-photographs, and satellite imagery. Findings reveal that erstwhile existing forests were destroyed mainly in the pursuit of expanding agricultural lands , while future degradation and depletion will likely be caused by fuelwood and fodder collection. Results of investigations into use and management of resources under both the public and the private domain show that caste level and landholding size were related to resource endowment and utilization intensity. Resource use and management systems were found being relatively sensible in valley settlements at accessible locations i n contrast to ridge settlements particularly at hardly accessible locations. Although numerous ridge households disposed of non-farming income , that finance had apparently not been invested in activities related to watershed management. Overal1, the resource use and management system was inefficient owing to the strong dependency on subsistence agriculture, characterized by an inadequate l and use system, small and fragmented landholdings, difficult access to support services and faci1ities, and backwash effects of market centers, compounded by somewhat lopsided and counterproductive changes in government forest policies over the past decades. To alleviate the pressure on watersheds and to institutionalize sustainable development , t he suggested multipronged watershed management strategy includes the creation of mass awareness, provision of manpower development training, adoption of an environmentally suitable and economically sustainable cropping system, promotion of agribusiness, improvement and strengthening of support services and facilities, establishment of agro-processing industries, and rehabilitation of critical locations. Recognizing the ecological variation, area specific and target group oriented watershed management programs are outlined in the context of this multipronged watershed management strategy.
