Soil, water and production systems constitute the most important natural resources of a watershed inthe rainfed agro-ecosystem; and for sustainability of the production systems they need to be in harmonywith the environment. To learn from the past research, a review is made of literature on the impact ofnatural resource management practices on soil and water quality in the semi-arid tropical regions ofIndia. The results from long-term on station field experiments show that an integrated use of soil andwater conservation practices with balanced plant nutrition can not only sustain increased productivitybut also maintain soil quality at the watershed or catchment level. Natural resource managementpractices that conserve soil and water also help to maintain surface and groundwater quality. Thechanges in soil and water quality, as impacted by natural resource management practices, need to bemonitored and assessed on a continuing basis as the outcome of such research offers valuableopportunity for the implementation of corrective management practices, as and when needed
