Redistributing power in food systems: how community-led responses move from crisis buffering to systems transformation.

چکیده اصلی

Food and nutrition insecurity in high‑income countries is increasingly persistent, driven by intersecting economic, social and environmental disruptions. In Australia, acute shocks such as the COVID‑19 pandemic, floods and bushfires, alongside chronic pressures including rising food prices, housing stress and concentrated corporate power, have exposed structural weaknesses in food access, governance and system resilience. This review examines how community‑led responses to food and nutrition insecurity function during disruption, whether they buffer short-term hardship or contribute to adaptive capacity and redistribution of agency. Guided by the six‑pillar food security framework and a socio-ecological model, responses are examined across household, community, organisational and governance levels. A continuum of responses is identified, ranging from downstream emergency food relief that buffers immediate hardship through to community and organisational food infrastructure that strengthens local resilience and governance‑level responses with greater transformative potential. Drawing on this synthesis, we propose the SEEDS (Socio-Ecological Enablers of Dietary Security) Model, which conceptualises how food system responses across socio-ecological levels and over time can progress from buffering (acute) to adaptation (medium‑term) and ultimately transformation (long‑term). Central to this framework is a shift in decision‑making power, accountability and participation. While many initiatives improve food access and short‑term stability during crises, the greatest potential for transformation lies where responses are embedded within governance structures, enable meaningful community participation and influence policy, procurement and resource allocation. Implications for public health nutrition practice include expanded roles in systems leadership, cross‑sector governance and advocacy for upstream policy reform.
