Abstract

Abstract Street traders play a key role in the food system in South Africa and many other countries. Despite their importance, the operations of street traders are not well understood and often undermined by policy makers and planners. This article provides insights into the role of street traders who sell food, in particular fresh produce, and the nature of their operations. It shares experiences of street traders in South Africa since the beginning of the Covid-19 pandemic and derives lessons from this for their contribution to food and nutrition security. The article is based on in-depth research carried out with street traders and other food system actors that they are linked to in three provinces (Gauteng, KwaZulu Natal and Limpopo) of South Africa. It was found that the street traders were severely affected during the first hard lockdown and continued to suffer due to the drop in aggregate demand that has resulted from the reduced incomes of many of their clients. They have also not been able to access the government Covid-19 recovery funds. Despite these challenges, street traders have continued to perform an even more essential role in making fresh produce accessible. This is in contrast to supermarkets that have maintained higher prices and profit margins despite the state of disaster affecting people’s ability to buy. Street traders are deserving of greater recognition and support as they play a key role in achieving food security and addressing other socio-economic challenges. Improving the conditions for street traders requires securing more public space for food trading and recognising and building on the ways that street traders use space and organise their economic lives.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
