Toward understanding the governance of varietal and genetic diversity

Varietal and genetic diversity sustain modern agriculture and is provided by breeding systems. Failures in these systems may cause insufficient responses to plant diseases, which threatens food security. To avoid these failures, an understanding of the governance challenges in providing varietal and...

We consider breeding systems as social-ecological systems that focus on activities that generate varietal and genetic diversity and their adaptive ability.
