This article investigates the impact of North-eastern Region Community Resource Management Project for Upland Areas (NERCORMP) and draws inferences on mechanism of change, context of an intervention and implementation design. Utilising data from three waves of surveys, we find that while there is evidence of significant changes in financial inclusion, productivity and social security, there are some issues in replication and sustenance aspects. Since the impact of intervention is observed across various domains such as socio-economic situation and natural resource management, thus, we believe that this paper presents an important case study in understanding the intervention efficacy, relevance and sustenance.
