Abstract

Natural resource management (NRM) is an impertant issue to be addressed carefully, more so in the semi-arid tropics where majority of the rural livelihoods are dependent on agriculture, Water scarcity and land degradation are the major constraints along with poor socio-economic conditions and lack of infrastructure for increasing agricultural productivity of rainfed systems. The sustainability of production, soil quality and other environment resources are the major impact factors of INRM. With watershed as an entry point, assessing the impact of integrated natural resource. management (INRM) interventions offer useful information 'on the performance of agricultural watersheds. Pathways of impact in watersheds are multi-pronged (Fig. 1) and complex demanding critical analytical framework to assess the impact of . watersheds. Agricultural interventions typically involve opening closed natural systems thai may have attained certain equilibrium; Such products as food, feed, fuel, etc. are exported from the system reSUlting in more outflows than inflows. When this happens, unless outflows are complemented by external inputs, resource productivity will gradually decline. Land degradation is a commonly used term to describe this situation and refers to the productivity loss andj or diminishIng ability of land to provide such esst;ntial ecological services as groundwater recharging, carbon fixation and storage, detoxification o f harmful compounds, and water purification. In order. to minimise the process of degradation and to maintain productive capacity and ability to provide ecosystem services for present arid future generations, various natural resource management (INRM) options have been developed and implemented (Wahi et al., 2004).
