Designing mixed cropping systems and transition paths towards sustainable ecology based agriculture.

We study the transition to sustainable ecology-based agriculture by using mixed-cropping systems that combine multiple crop species on a single field. Our team elucidates the ecological processes that make mixed cropping systems sustainably productive and we identify which socio-economic and societal or institutional factor need to be resolved to overcome the lock-in in current conventional farming systems. To allow a broad spectrum of farmers, consumers and stakeholders to reach transition goals, we embrace variation in transition paths. We explicitly compare how existing international value chains require adjustments as well as how new short and local value chains can emerge.
