Abstract:

Plant biodiversity within agricultural ecosystems is a central asset for food security, dietary diversity and ecologically and socially sustainable farming. A key question is how the diversity of seeds and the access to them can be maintained. As human activities have fragmented natural habitats, altered agricultural environments, and facilitated global-scale connections, understanding the diffusion of genetic resources within and among locations has become particularly important. Farmers use, produce, select and conserve biodiversity through their management of seeds, which depends on the ecological and evolutionary processes operating in their fields as well as the flow of seeds among farmers through social exchange. Seed exchange networks thus mediate the diffusion of genetic resources, and integrate natural and social dynamics into the dynamics of agricultural biodiversity.

Network analysis can reveal new relationships between society and biodiversity, and provides a tool that can help support farmers in the maintenance and management of seed flow networks, enabling human communities to adapt to the changing cultural, economic and environmental conditions that characterize our world today.
