The Deccan region of South India principally supports rainfed agriculture and is home to a fascinating biodiversity of crops. Millets, legumes, oilseeds and wild edible plants produce an incredible and diverse matrix in farmers’ fields. Medak district in the south Indian state of Andhra Pradesh, where the Deccan Development Society (DDS) works, has thousands of amazing women farmers who have kept alive a vibrant diversity of plants and animals on their farms and in their fields. These women, despite being marginalized and working marginalized lands, have courageously preserved and conserved agricultural biodiversity in the Deccan. The diversity sustained by these women is an unbroken tradition stretching back centuries and has inspired the DDS’s biodiversity festivals. Over the last seven years these festivals have traveled a remarkable distance. They have moved ecological agriculture from an environmentalist’s agenda to a farmer’s agenda. They have moved agro-biodiversity out of a sanitised laboratory environment into a vibrant community celebration. They have elevated agricultural biodiversity from the concern of small farmer groups to become a national concern. They have provided a new path and vision for the National Biodiversity Action Plan of a vast country like India. Through an exciting community process they have redefined ecology, agriculture, biodiversity and governance. People’s Agenda for Biodiversity faithfully chronicles the journey of the Mobile Biodiversity Festival organized by the sanghams and the Deccan Development Society.
