Traditional seeds are an important tool for strengthening the resilience of farming families in the face of climate change. And they offer food sovereignty and security at lower cost. However, the range of seed varieties is shrinking all the time. This is due to market domination by agro-industrial groups and regulations in their favor. Farmers can no longer freely plant, exchange and sell the seeds they have multiplied on their own farms. In its projects, SWISSAID promotes local seeds and encourages farmers to preserve, conserve and exchange their seeds. At the same time, it fights to ensure that seed regulations are more respectful of farmers’ rights, and opposes the privatization of seeds, both in developing countries and in Switzerland.
