Acoalition of researchers and policy experts has called for the introduction of state-managed food buffer stocks in South Africa as a means of addressing food insecurity, stabilising prices, and insulating consumers from global market shocks.
The proposal was presented in a new policy brief, Staple Food Price Trends in South Africa: A Case for Buffer Stocks?, launched at a hybrid panel discussion co-hosted by the Institute for Economic Justice (IEJ), the Rosa Luxemburg Stiftung, and the Heinrich Böll Stiftung Cape Town. The dialogue formed part of the ongoing G20 Dialogue Series on Food Justice, coinciding with the meetings of the G20 Agriculture Working Group and Food Security Task Force in Cape Town, in preparation for the 2025 G20 Summit in November.
Advocates of the approach argue that public buffer stocks could provide stability in a sector marked by volatility. By purchasing staple grains when prices fall and releasing them during price surges, such reserves can help to moderate inflationary pressures, support smallholder farmers, and strengthen resilience in the face of climate variability and drought.
Sophia Murphy, executive director of the Institute for Agriculture and Trade Policy, emphasised that buffer stocks represent “an age-old solution to a perennial problem”, noting their ability to reduce unpredictability for both producers and consumers. Unlike private stockholding, which often profits from speculation, public reserves would be geared towards transparency and food security.
Andrew Bennie, a senior researcher at the IEJ, situated the call within a global trend. He explained that public stockholding mechanisms gained renewed attention after the 2007–2008 and 2022 global food crises, when price spikes intensified hunger despite sufficient global production. Bennie argued that the model could be implemented at multiple scales – from community-based reserves to regional arrangements across the Southern African Development Community (SADC) and the African Union (AU).
Refiloe Joala, programme manager for food sovereignty at Rosa Luxemburg Stiftung, highlighted the structural drivers of South Africa’s food price instability. While international commodity prices frequently decline, she noted, local consumers often face persistently high retail costs due to profit margins in processing and retail. For Joala, buffer stocks would not only ensure emergency availability but also provide a state-led mechanism to temper these distortions. She stressed that transparency and rigorous oversight, particularly through contracts with smallholder farmers, would be vital to ensure inclusivity and accountability.
The discussion reflects broader continental debates on food security and sovereignty, where African states continue to navigate the interplay between global markets, climate disruptions, and domestic inequalities. Aligning with initiatives under the SADC, the AU, and the G20’s food security agenda, proponents argue that buffer stocks could be a practical tool to reduce vulnerability while fostering more diverse and locally rooted food systems, including indigenous grain production.
While the concept is not without its challenges – particularly in terms of governance, cost, and political will – the proposal adds weight to ongoing calls for systemic interventions that move beyond short-term relief. By anchoring food policy within regional cooperation and long-term resilience, buffer stocks are increasingly framed as one of several strategies capable of addressing the structural roots of hunger in South Africa and across the continent.
