Food Security Policy Analysis Using System Dynamics: The Case of Uganda

Food security FS challenges exist in both the developed and the developing countries, the difference being the severity and the proportion of the population affected. Previous studies maintain that chronic food insecurity at subsistence farming level has persisted due to a number of factors including unsustainable subsistence agriculture and livelihood policies, lack of inputs, poor conservation methods, weak extension services, unregulated markets, limited land among others. This article investigates FS challenges at subsistence farming level using system dynamics tools. The emerging system dynamics model is conceptualised into four sectors; food production, sales, income and food consumption, representing a real-life food security system. The model is used to evaluate policies for better livelihoods as well as explore strategies for profitable subsistence farming and food security.
