Community seed banks in northern Tanzania are playing a crucial role in strengthening food systems and enhancing farmer resilience. These banks preserve local seed varieties, safeguarding biodiversity and traditional agricultural knowledge. Farmers in the Karatu and Arusha districts have long depended on these farmer-managed seed systems for their livelihoods. The initiative supports food security by providing access to diverse and adapted seeds, particularly important in the face of climate change and environmental challenges. By controlling their own seed supply, farmers reduce reliance on external inputs and maintain autonomy over their agricultural practices. These seed banks are therefore becoming vital components of sustainable agriculture in the region.
