The idea of SeSTA was conceived in the year 2011 to catalyze the development activities in NE-India through the process of “Nirman” (constructive development) by working for an improved Livelihood system and better well-being status of rural communities of the North Eastern States of India. SeSTA is conceived to put effort as a catalyst for the economic development of NE India by building capabilities of rural communities, promoting and strengthening their institutions so that they could come out of the vicious cycle of contested identity war, and poverty and be able to participate in the global economy.
