The formation of a biodynamic seed network has been developed over several years by the ABD. The current project seeks to strengthen the seed network groups through the formation of a network of small community seed houses which are connected to the ABD mother bank. In selected locations in the states of São Paulo and Minas Gerais, the project uses native seeds in the biodynamic management of groups of family farmers and agrarian reform settlers, based on the concept of constant awareness of farmers regarding the importance of producing and conserving their own seeds. The seed as a universal patrimony of people and as a fundamental asset for food sovereignty, in the face of pressure from the conventional seed market.
