Political Agroecology In Syracuse: Local Understandings, Possibilities, And Barriers To Food System Transformation, Cooper Olds

Theses - ALL

In recent years, agroecology has begun to receive increasing attention from international institutions such as the United Nations Food and Agriculture Organization (UN FAO). For some, this is seen as a valuable case of up-scaling agroecology which will lead to greater institutional support for the framework. However, critical agroecologists have raised concerns that such institutional adoption is rather a form of co-optation where the social and political elements of agroecology are omitted to facilitate the integration of the framework into a wider program of food system reform. As a result, there is ongoing contestation over the framework between these co-opted …
