Description 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).
