Abstract:

In this study, the authors test their hypothesis that seed turnover is an important component of farming systems rich in biodiversity. The authors suggest that this finding conflicts with conservation initiatives that focus on preventing changes in varietal preference. They also explore the relationship between marriage patterns and networks of seed exchange. They discuss potential conflicts between common interventions and local exchange systems that are embedded in cultural practices.
