Operationalising food sovereignty through an investment lens: how agro-ecology is putting ‘big push theory’ back on the table

A central question in the current debate on food sovereignty concerns the concepts and approaches to assist and frame the operationalisation of its agendas for peasant-based agricultural development. Another is the search for inclusive methods and language to discuss these operational, ‘territorial’ agendas with potential constituents. This paper argues that both questions call for an investment lens, a complementary approach within food sovereignty that proposes and discusses investments rather than political demands. Decolonial epistemology will treat existing investment lenses critically; however, in doing so it also urges new perspectives on what constitutes investment, the categories of cost involved, and the measurements employed. In following the rationale of investment in agro-ecological theory and practice, the paper next argues that the reconstruction of ‘big push theory’ outside the ‘modernisation’ paradigm that once produced it is possible, and that formulation and discussion of big push strategies could reclaim a space within critical agrarian studies. Big push theory offers a frame for the consistent critique of ‘silver bullet’ development projects through the study of negative feedback loops; and a frame for the study of positive feedback loops, which crucially underlie the proposals of food sovereignty movements for broad, integrated changes in agrarian systems.
