Methods for understanding complex systems: A protocol for a systematic review in the field of food systems
Global Food and Nutrition Security

This protocol introduces a systematic mapping review to explore the scope, variety, and characteristics of methods used in food systems assessments, a novel approach that examines how food systems influence outcomes such as diets, nutrition and health, environment, economic, or social equity. While frameworks for these assessments have gained consensus, the inherent complexity of food systems—characterized by diverse stakeholders across multiple sectors—creates challenges in achieving methodological clarity. Existing empirical research in food systems and nutrition remains in its early stages, with limited attention to critical aspects such as backward linkages and dynamic interactions within these systems. This protocol presents a systematic mapping review to identify gaps in current methods and explore the potential of complex systems methods. An interactive Evidence and Gap Map (EGM) will visually synthesize and classify the available data. Ultimately, this synthesis aspires to advance food system methods, identify trends, and guide future research and policy priorities in this vital field.
