Boundary development in the field of international nutrition science.

Using a sociological approach that elaborates on key observations of institutional entrepreneurs in international nutrition, this paper explores institutional boundaries and boundary work in international nutrition. Sociological concepts of "boundary making" and "situated knowledge" are applied to the boundaries between the nutrition sciences and lay nutrition knowledge in nutrition intervention. These concepts allow an analysis of how nutrition science creates boundaries between its field and other sciences and between nutrition as a science and other nutrition practices, providing additional perspective on current challenges in global food security and malnutrition. Analysis of boundary processes in international nutrition can also illuminate the development of "implementation" or "delivery science" in the field of international nutrition as it attempts to strengthen effectiveness of global efforts to reduce malnutrition. Although some risk taking in the academic world is rewarded, the analysis indicates that there are underlying processes that may inhibit full partnership with local people in the course of intervention work that builds scientific nutrition knowledge. As nutrition science becomes increasingly central to development, the boundaries that are reinforced by digging in heels over the implementation of programs with little local input or softened by inviting local stakeholders to publicly consider the problems in global nutrition together are important to consider in helping to create directions that favor viable solutions.
