Transdisciplinary Approaches and Methods in the Context of Food and Nutrition Security.

Abstract

Since the World Food Summit of 1996, the world has strived to achieve sustainable food production and improved nutrition for all. However, the complexity of food and nutrition security, compounded by a growing population, depleting natural resources, changing consumption patterns, and a multitude of environmental shocks to the ecosystem, make it a "wicked problem." Wicked problems transcend the resources of any single discipline and are the focus of contemporary transdisciplinary work. Transdisciplinary research approaches allow us to gain a better understanding of complex contexts, actions, and decisions that determine socioecological systems, and to develop organizational, social, and technological innovations that fit a given situation. Using the case of urban agriculture, which holds both potential and challenges for healthy nutrition and food systems, the key features of transdisciplinary research approaches are identified. As transdisciplinary research stems from a perceived real-life problem, a differentiated understanding and handling of knowledge diversity is needed. Furthermore, there is the need to build and maintain a research team and depending on the number of actors and the diversity of interests involved, the research has to be conceived as a group working process over a period of time requiring group management and process design skills. Though there is no single recipe for a transdisciplinary research process, we present a framework for such a process with iterative loops and multiple interactions among the various spheres of actors through the 4 phases of problem framing, problem analyses, problem solving, and stimulating change. Transdisciplinary research approaches have many challenges and are demanding in the integration of the research environment and processes. The interaction between stakeholders and the joint learning and reflection processes necessitate mutual understanding. However, the management of these interactions is as vital as pure scientific analysis for tackling real-world challenges.
