| 520 | _aHow can the conditions of ·the people living in degrade mountain watersheds of Nepal improved without further: degradation of the watershed ecosystem? The technical solutions derived from qualitative assessments of watershed conditions in the past has not helped much to answer to t-he issue raised by this question. It calls for a methodology, based on a quantitative approach , for beiter understanding of the local environment. This must be supported by the local farmers responses in order to develop recommendations for: watershed management strategies and to implement the program through the farmers participation. This study demonstrates a methodology to quantify two key physical indicators of watershed conditions and identify the ensues for the change in surf ace 1."'Unof f and high soil erosion rates . The findings from the physical modelling are supported by field data. The study carried out on Nakkhu Khola watershed, indicated that surface runoff increased over time. Soil erosion rate from the watershed area is very high. However, the mass wasting dominate tr1e total sediment load in the river downstream. The major physical and socio-economic factors of degradation analysed were increase in population, high susceptibility of mountain ecosystem to landslide frequency. The present management strategy has to be changed because , the objective is very narrow , the scale of activities is quite low , and the program does not provide initiative to the farmers for launching conservation management activities. Resource management actions an':' recommended to improve the condition of the watershed by increasing local farmer participation. | ||
