On-farm seed banks are a grassroots approach to conserving agricultural biodiversity. They work by allowing farmers to collect, store, and exchange locally adapted crop varieties. These banks act as living libraries of seeds, safeguarding genetic diversity while ensuring access to resilient and region-specific plant strains. By empowering farmers to manage their seed resources, on-farm seed banks play a vital role in preserving heritage crops, promoting food security, and enhancing agricultural resilience to changing environmental conditions.
