Tribal and rural communities have contributed to conservation of nature and natural resources (Swaminathan, 2000). The traditional knowledge associated with agro-biodiversity resources is important in on-farm conservation. There is rapid erosion of agro-biodiversity evident across the world, particularly in the case of neglected and underutilized crops (NUS) (King, Nambi and Nagarajan, 2009). Nutri-millets like Little millet, Italian millet, Finger millet, Kodo millet and Common Millet are notable among the NUS crops as these crops are nutritionally rich and being neglected, yet are also known to be climate-resilient crops. These crops play a crucial role in the food and nutritional security of the poor communities in marginal environments (Bhag Mal, Padulosi and Bala Ravi, 2010). This paper
shares experiences and lessons regarding on-farm participatory documentation and monitoring of millet diversity in the Kolli Hills of southern India.
