Managing on-farm landrace mixtures for organic farming

On-farm management of landraces and old varieties enhances biodiversity and supports organic farming through dynamic populations that adapt annually to local conditions. Farmers use continuous selection, local seed processing, and small-scale multiplication to maintain seed quality and viability. Collaboration with seed associations and community seed banks addresses technical and economic challenges, enabling market access for heterogeneous seed mixtures under new regulations. This approach strengthens local food systems and ecological resilience, supported by INRAE.
