Relative ease in promotion of local food for cultivation, consumption and value addition </p><p>analysis, nutrition and income 4. Developing value chain for farm produces, involving network of women SHGs and </p><p>supported by skill development, access to char credit, market linkage, and also char advocacy (no chemical fertilizers) </p><p>5.
