The purpose of the Integrated Natural Resources Management program in the Middle East and North Africa Region (MENARID) is to bring national investment projects in the field of Integrated Natural Resource Management (INRM). The impact evaluation study tests whether the selected technology has significantly contributed to restore and maintain of the ecosystem functions and productivity, and whether has improved the economic and social well-being of the targeted communities. We chose Kamkooyeh Village in the Behabad County where a "Village Development Group" (VDG) has been established by following participatory and capacity building approaches such as social mobilization and micro credit mechanism. A set of complementary activities and interventions were recommended and implemented in the site by consultation and active participation of the local communities and beneficiaries. One of the proposed interventions is rangelands rehabilitation project (RRP). The expected benefits and costs of the RRP were predicted through financial valuation and an ex-ante evaluation of socioeconomic impacts. The financial and social benefit-cost ratio of RRP was estimated to be about 0.97 and 2.15, respectively. Manuscript profile
