A North-West University (NWU) expert in consumer sciences recently served as guest editor for the first special issue of the South African Journal of Science focusing on sustainable food systems in southern Africa.

Prof Annchen Mielmann says this landmark issue brings together contributions from a wide range of disciplines that deepen understanding of food sustainability, food security and nutrition in southern Africa. It features a guest leader and perspective, three commentaries, two review articles, and thirteen research articles. Collectively, these works highlight the vital role of local food systems in stimulating the production of healthy, safe and sustainable food resources.

A regional challenge, a global goal

Prof Mielmann notes that southern Africa faces complex challenges in creating sustainable food systems due to environmental, social and economic pressures. “There is a need for a platform where the scientific community from the region can exchange expertise and data to design tools, strategies and interventions suited to diverse contexts and populations.” Such efforts, she adds, are essential for making diets healthier, strengthening food systems, and advancing progress towards the achievement of the United Nations’ Sustainable Development Goals.

She raises a key question in the issue: “Will protein diversification lead to sustainable food systems in southern Africa?” Prof Mielmann argues that recognising the value of protein pluralism could play a pivotal role in ensuring a more resilient food transition for the region.

According to her, the findings presented reaffirm that the strengthening of African food systems demands a modern, multi-faceted approach. This includes innovation and knowledge, technological advancement, digital tools, trade and creative financing.

“Crucially, the transformation of current food systems into more sustainable ones will not occur automatically. It requires new approaches to food system governance, where farmers, agri-food businesses, financial institutions, governments, non-governmental organisations and other stakeholders engage with and influence one another to achieve shared objectives.
