The annual indigenous traditional community seed festivals have been an ancient practice in India and an integral part of the indigenous farming culture. There is no gainsaying that conservation of agro-biodiversity and agro-ecology is indispensable for food security and indigenous farmers realized it long ago. As an ancient practice, the indigenous farmers in India have been exchanging indigenous heirloom seeds not only among themselves but also passing down the generations both the knowledge and heirloom seeds through observation of indigenous traditional community seed festivals. The indigenous traditional community seed festivals have an inbuilt conservation aspect to it, which acts as the indigenous agro-biodiversity keeper. The indigenous traditional community seed festivals act as a means of exchange of indigenous heirloom seeds and act as a repository to conserve and increase indigenous heirloom seed diversity, agro-biodiversity, and diversity of the traditional food basket.
