Linking Material Flow Analysis with Resilience Using Rice: A Case Study in Global, Visual MFA of a Key Food Product
This article uses the rice price crisis of 2007-2008 to show how material flow analysis (MFA) can be combined with resilience research. After presentation of fundamental information and methods, resilience-related concepts are illustrated using graphical methods and MFA data. Herfindahl-Hirschman Index (HHI) and node-link diagrams are used to highlight potential vulnerability hotspots and show response to, recovery from disturbance and adaptation following a disruption of the global rice market. The methods presented are especially useful in rapid screening for potential impact of supply-side disruptions, such as export restrictions or poor harvests. The article concludes by discussing other potential applications of the chosen approach and stressing the importance of visual communication in dissemination of results and cross-pollination between disciplines. All the data used in this study is available online, as interactive visualizations, at: http://ricestudyvis.weebly.com.
