The channel that feeds most of urban Africa’s poor appears in almost no official statistic. Informal traders and hawkers move a large share of South Africa’s and the region’s fresh produce to low-income consumers — in small quantities, at low margins, in the exact neighbourhoods that formal supermarkets reach last. The contradiction is sharp: the most economically important food channel for the urban poor is also the one policymakers most often treat as a problem to be cleared.
South Africa’s experience is the working baseline. Its spaza shops and street traders form a fresh-produce distribution layer that buys from municipal markets and sells onward in single tomatoes and small bundles — volumes a supermarket cannot profitably handle. The National Agricultural Marketing Council has documented how this informal tier connects formal wholesale markets to consumers who would otherwise be priced or distanced out of fresh vegetables altogether.
The Mechanism: How the Informal Channel Actually Works
The informal trader performs three functions the formal chain struggles to replicate. The trader breaks bulk, selling quantities a low-income household can afford on the day it has cash — a single onion, a handful of spinach, two tomatoes — volumes for which a supermarket’s cost-to-serve is simply too high. The trader sits inside the neighbourhood, often within walking distance, sparing the consumer a transport cost that can exceed the price of the food itself and that no formal store sited on an arterial road can match. And the trader extends informal credit and flexibility no till system offers, carrying a known customer to the end of the month on trust. This is not disorder; it is a finely tuned distribution system optimised for thin wallets and irregular income.
It is also a substantial employment channel in its own right. The trader is usually self-employed, frequently a woman, and the chain behind each stall — wholesalers, transporters, market porters — supports livelihoods that rarely register in formal labour statistics. To treat the informal channel as merely a distribution gap to be closed is to miss that it is simultaneously a jobs base for the very people it feeds.
The informal trader is not the absence of a system — the trader is the system the poor can actually afford.
The Comparators: The Same Backbone, Different Politics
The comparators show the channel under varying official pressure. In Zambia, urban fresh-produce markets and street vendors are the dominant route to low-income consumers, and periodic formalisation drives raise the perennial question of who is displaced. In Zimbabwe, economic stress has pushed even more food trade into informal hands, making the channel less a choice than the default food system for much of the population. Kenya’s vibrant informal markets — the mama mboga vegetable sellers among them — coexist with a strong formal retail sector, showing that the two channels can run in parallel rather than one extinguishing the other.
The pattern across all three: where formalisation clears traders without replacing their function, the poor lose access before they gain anything.
The Verdict: Formalise the Function, Not Away the Trader
The honest verdict is that formalisation is neither inherently good nor bad — it depends entirely on whether it preserves the channel’s function. Food-safety gains, traceability and fair tax treatment are legitimate goals. But a formalisation drive that bulldozes stalls, imposes fees the trader cannot meet, or routes fresh produce only through outlets the poor cannot reach does not formalise the food system; it removes it. The Food and Agriculture Organization consistently frames informal food markets as essential infrastructure for the urban poor, and World Bank agriculture and rural development work cautions that heavy-handed regulation can deepen food insecurity rather than improve it.
The verdict: the question is not whether to regulate, but whether the regulated channel still feeds the same people.
The Forward Action: Upgrade in Place
What must be in place is upgrading rather than clearance — designated trading sites with water, waste handling and basic cold storage; light-touch registration that brings traders into the system without pricing them out; and food-safety support delivered as training, not eviction. The aim is a cleaner, safer informal channel that still serves the consumer it was built for.
South Africa’s informal fresh-produce economy is the continent’s most studied example of a channel that is simultaneously a backbone and, badly handled, a bottleneck. It is a template for emulation where it keeps food cheap and close — and a warning to improve upon wherever formalisation forgets who the informal trader actually feeds.
