Conservation of indigenous species of food crops -best practice

Subject: Government Schemes

• Around 20 heritage rice varieties of Tamil Nadu are being traced, collected, redeemed, and restored at least through 10 community seed banks benefiting more than 500 farmers in the state.
• These varieties had been identified for their unique nutritional, medicinal, and ecological qualities and, above all, their climate resilience.
• The majority of small & medium farmers of Tamil Nadu have lost their heritage seeds, once owned traditionally by their community forefathers, due to
• monocropping of hybrids.
• The genetic erosion of heritage and indigenous gene pool of paddy varieties,
• loss of knowledge on the therapeutic/curative properties of native extant varieties,
• lack of accessibility to their seed stocks

Steps taken

• These community seed banks have been promoted by identification of willing farmers based on location with assistance from local NGOs in 24 districts 
• A lead farmer cultivates one to many traditional varieties in his farm, a part of which when harvested is shared and distributed to other interested farmers in the neighbouring localities and districts with or without payment. This is an informal structure with voluntary participation.
• A seed bank capital of Rs. 2000 was distributed to each beneficiary farmer to strengthen the heritage rice community seed banks.
• The initiative by SASTRA Deemed to be University, with support from the Science and Heritage Research Initiative (SHRI) programme of the Department of Science and Technology (DST), is reviving, conserving, and characterizing the traditional rice varieties.
•  Paddy seed exchange festival – ‘Nel Thiruvizha’ organized along with CREATE- a Tiruvarur-based NGO, helped distribute heritage rice seed varieties such as Karuppu kouni, Thuyya malli, Mapillai samba, Karunkuruvai and so on
•  The farmers are trained in conservation methods and ways of enriching and revitalizing the indigenous heritage germplasms, as well as on In situ trials for climate adaptability in the farmer’s field on a pilot scale.
• The initiative to collect & conserve the traditional landraces of rice varieties can help share and exchange knowledge about the varieties with inherent capacities to withstand climate uncertainties, drought and flood resistance, medicinal and nutritional properties. Once the knowledge about these local indigenous rice varieties spreads beyond the tiny localities to which they are confined, farmers can participate in preventing the erosion of the knowledge.
• The initiative can bring sustainable yield to all rice-based farmers in the event of climate change uncertainties. ‘Seeds of Past’ conserved to reserve ‘Seeds for future’ can be promoted for upscaling in coming years.
