Applying Community-Based system Dynamics to Address Food Insecurity in Non-Remote Indigenous Populations in Australia

Abstract

Abstract Objectives There is a growing crisis of hunger and food inequality among Indigenous people in Australia who are increasingly urbanized. They experience substantially higher rates of food insecurity than the general population which impacts on diet-sensitive chronic disease risk and life expectancy. This project aimed to apply systems tools to identify systemic challenges to achieving food security and possible local actions to address the problem in two large Aboriginal communities. Methods A qualitative system dynamics method used group model building (GMB) in two regional and outer urban communities involving participants from Aboriginal Community Controlled Health Services, food relief charities, council, educational groups and some food industry partners in the two local areas. The GMB enabled the participants to consider all the connections between contributing factors, feedback and reinforcing loops to produce a map of food insecurity linked to the local food system. This project was done in collaboration with the Study of Environment of Aboriginal Resilience and Child Health (SEARCH), Australia's largest cohort study into the health of urban Aboriginal children. Results The GMB workshops resulted in causal loop diagrams that mapped the complexities of the food insecurity challenge. The maps highlighted the impact of low incomes and unemployment that influenced the communities’ ability to budget and afford healthy food, thereby leading to a reliance on convenience food outlets. This, in turn, influenced communities’ healthy food preferences, which negatively impacted on food security. Additionally, community education around healthy food choices, meal planning and financial literacy were factors that also directly impacted food security. A distinct loop reflected that a lack of coordination between agencies was leading to duplication and confusion about available food relief services and the ability to access these services. Conclusions These analyses elicited local understanding of the potential levers within the system to address food insecurity in Indigenous people. They are being used to develop community-level workplans to shift the high prevalence of food insecurity and its longer-term impact on preventable chronic disease.
