Abstract
Food security is an unresolved issue, especially so among developing countries. Models of food security usually focus on the farming components (availability) and neglect to fully incorporate its multi-dimensional nature: including access, utilization and stability (of food). This article proposes the design of an empirical agent-based model representing Malawian smallholders, which operationalizes the FAO framework on food security at the household level. While the general structure can be customized and replicated for other contexts, the agents’ characterization is based on national survey data. Preliminary results suggest that non-agricultural workers are more food secure. However important feedbacks with the natural (ecosystem services) and the economic system (local/international market) are foreseen but not fully implemented.

This work was supported by an EPSRC Doctoral Training Centre grant (EP/G03690X/1). It was also inspired by an ESPA funded research project: Attaining Sustainable Services from Ecosystems (ASSETS), which aims to “explicitly quantify the linkages between ecosystem services that affect—and are affected by—food security and nutritional health for the rural poor at the forest-agricultural interface” (http://espa-assets.org/). The participatory rural appraisal (PRA) carried out by the University of Southampton and LEAD-SEA, Malawi in the Zomba and Machinga districts of Malawi (6 villages of Chilwa East and West areas) was subjectively interpreted by the authors to build the model general framework which was subsequently assessed by project experts.
