Food security outcomes in agricultural systems models: Case examples and priority information needs

Abstract Analyses of food security with agricultural systems models often focus on indicators availability, limited treatment the other three dimensions: access, stability and utilization. We illustrate how access (food consumption expenditures, a insecurity scale dietary diversity) their can be incorporated into dynamic household-level model maize-based production system in Kenya highlands regional sheep marketing Mexico. Although stylized due to limits empirical evidence, analyses suggest that inclusion multiple provide insights because respond differently shocks, demand growth programs providing subsidies. also examine outcomes response shocks using metrics hardness (ability withstand shocks) elasticity return previous conditions).
