In the year 2011, the Ministry of Rural Development, Government of India launched a poverty Alleviation Project after taking into considerations the loopholes in the preceding Rural Development projects viz., IRDP and SGSY. In Nagaland, it was launched in 2012 and Nagaland State Rural Livelihood Mission (NSRLM) is the implementing agency for NRLM in the state. This research is a comprehensive work on the performance of NSRLM and contains information on the status of implementation of the mission with reference to NSRLM vision 2025; the effectiveness of the Community Based Organizations of the mission; the impact of the mission on the livelihood status and socio-economic status of the beneficiaries as well as the constraints of various stakeholders of the mission has been identified and presented. Through this study, the author/researcher has also developed a Livelihood Vulnerability Map (LVM) window for unskilled livelihood activities and using it, the vulnerable sections of the people can be identified with better accuracy. I am convinced that the book �Performance Assessment of Nagaland State Rural Livelihood Mission� can be used as a guide by the policy makers in formulating better policies and strategies for the future. It also highlights the necessary and appropriate approaches to be undertaken when implementing other extension activities particularly in addressing poverty alleviation and developing modules to reach out to the target groups. It will also help in minimizing the gaps when working with the target groups particularly the Self Help Groups and the Community Based Organizations.
