Agroecology is our best option for creating an agrifood system capable of nurturing people, societies, and the planet. But it is still not widespread. Fertile Ground offers nine case studies, authored by agroecologists from Africa, Latin America, the Caribbean, North America, and Europe, that demonstrate how the endogenous practice of agroecology can be “scaled” so that it is known by more farmers, practiced more deeply, and integrated in planning and policy.
