A network of communities in West-Central Mexico has rescued its traditional landraces of maize. This experience shows that the benefits of defending an ancestral good is not only limited to regaining cultural identity and agrobiodiversity. The defence of native maize has become a space where old and new knowledge redefined
agriculture and where people achieved food sovereignty, technical autonomy, and a new sense of community.

Victor M. Toledo is a Mexican ethnoecologist and social activist at the National Autonomous University of Mexico. His work focuses primarily on the study of agroecological and knowledge systems. In this interview, Victor M. Toledo explains why co-creation of knowledge is an integral part of agroecology and discusses the changes that are needed for this form of agriculture to gain ground in the global
arena. He argues that agroecology is in itself a major shift in our relationship with knowledge.

Farmers are plant breeders when they select and save the seeds of the plants best adapted to the conditions in their fields. For over two decades, farmer breeders in Honduras have been working with scientists and NGOs to develop new bean varieties. In a context of high agrobiodiversity, limited public sector agricultural research capacity and extension services, the process has not always been smooth. Against all odds, this collaborative effort, which has brought scientific knowledge together with farmer knowledge, has positioned farmers at the forefront of innovation for climate change adaptation. This article highlights lessons learned over 20 years about the power of knowledge co-creation.

For the past half century agricultural innovation has denied a voice to the many groups who work outside the profession of science – farmers, food providers, women and the urban poor. The value of their expertise gained through practical experience must be recognised in the production and validation of knowledge.

Professor Steve Gliessman and farmer Jim Cochran are among the movers and shakers of the strawberry sector in California. Since the 1980s they have been experimenting with sustainable ways to grow strawberries and with alternative food networks. Committed to the agroecological transition, they built a powerful farmer- researcher partnership that was groundbreaking for farmers, academia and the strawberry industry as a whole.
