The document discusses setting up a national-level Solution Exchange in India to connect development practitioners and tap into India's vast knowledge to address development challenges. It would have active communities of practice on topics like water, food security, health, and more. Specifically, it outlines the Food and Nutrition Security Community which has over 1,400 members and focuses on sustainable food production and reducing malnutrition. Solution Exchange would provide online discussions, consultations, and collaboration between members. The long term plan is to sustain 14 communities and expand the model to other countries.
