African post-harvest losses for perishable produce have been reported above 30 percent in multiple markets, one of the highest loss rates in the world. Twiga Foods reduced its sourced-farmer loss rate to 4 percent. ColdHubs extends perishable shelf life from 2 days to over 21 days with solar-powered storage. This report maps the cold chain and food logistics landscape and the operators working to close the loss gap.
African post-harvest losses are among the highest in the world. The Food and Agriculture Organization and multiple other sources have reported that fresh produce losses can exceed 30 percent in many African markets, meaning that nearly a third of what farmers grow spoils, is damaged, or becomes unsellable before it reaches a consumer. These losses represent both a food security disaster (food that could have been eaten is thrown away while millions remain food-insecure) and a commercial tragedy (farmers who invested in production receive no value for the lost portion). The root causes are specific and known: inadequate cold storage, poor road infrastructure, fragmented logistics, weak packaging, and limited processing capacity that could convert perishable crops into shelf-stable forms before they spoil. This report maps the cold chain and food logistics landscape, the operators attempting to improve it, and the structural conditions that make the problem hard to solve at scale.
Five factors account for most African post-harvest loss. First, harvesting practices that are labor-intensive, slow, and damaging to produce (bruising during handling, crushing during transport, exposure to sun and heat during field collection). Second, the absence of field-level cooling, meaning that produce begins to deteriorate immediately after harvest in tropical conditions. Third, transport over unpaved or poorly maintained roads that subjects produce to vibration, temperature variation, and extended travel times. Fourth, market and storage facilities that are not temperature-controlled, leaving produce exposed to ambient conditions for the duration of its sale cycle. Fifth, limited processing that could convert surplus production into preserved forms (canned, dried, frozen, or ingredient-processed) during peak harvest periods.
Each of these factors is addressable with the right combination of infrastructure investment, operational discipline, and business model innovation. But no single intervention solves the problem, and the operators who have achieved meaningful loss reduction have typically done so by addressing multiple factors simultaneously rather than focusing on one.
Twiga Foods, the Kenyan B2B agri-logistics company founded in 2014, built its business around the post-harvest loss problem. The company sourced produce directly from smallholder farmers, organized delivery through its own logistics network, and sold to small and medium retailers in urban Nairobi. According to company reporting, Twiga reduced post-harvest losses from approximately 30 percent (the baseline for the informal Kenyan fresh produce trade) to approximately 4 percent (the rate Twiga achieved within its own sourced-to-sold chain). This is a dramatic reduction, and it was the core impact story that Twiga used to attract investor attention and customer loyalty during its growth phase.
The reduction was achieved through a combination of direct sourcing (reducing the number of intermediate hands), dedicated logistics (ensuring predictable transport timing), and aggregated selling (reducing the time between harvest and final sale). Notably, Twiga did not achieve its loss reduction primarily through cold storage. The company's model focused more on speed and handling quality than on temperature control per se, because cold storage infrastructure is expensive and difficult to scale across rural collection points.
The Twiga experience also illustrates the limits of logistics-led loss reduction. The company faced severe operational and financial challenges beginning in 2023, including a reduction of approximately 283 employees (roughly one-third of permanent staff) in August 2023 and a broader restructuring of its business model. The challenges were not primarily about loss reduction (which continued to work at the operational level) but about the unit economics of running a capital-intensive logistics operation in a market where the end customers (small retailers) have thin margins and the upstream suppliers (smallholder farmers) have limited price flexibility.
ColdHubs, founded in Nigeria in 2015 by Nnaemeka Ikegwuonu, has taken a different approach: decentralized solar-powered cold storage positioned at farm clusters and outdoor markets where smallholder farmers and traders operate. Each ColdHubs facility is a walk-in cool room that allows users to store fresh produce 24 hours a day using solar energy for cooling. The impact on shelf life is dramatic: produce that would spoil in approximately 2 days under ambient conditions can remain sellable for more than 21 days in a ColdHubs facility.
The ColdHubs model has reached 38 sites across 22 Nigerian states, according to company reporting, with plans to expand into East, Southern, and West African markets. Each site serves tens to hundreds of farmers and traders within its local area, extending their effective selling window and reducing the pressure to sell at distress prices during peak harvest periods.
The ColdHubs approach works because it does not require the user to own, maintain, or operate the cold storage infrastructure themselves. A farmer pays a small fee per crate per day for storage, which is affordable relative to the value of the produce being protected. The capital cost of the facility itself is borne by ColdHubs, which operates the site as infrastructure rather than as a transactional service.
Processing is a different approach to post-harvest loss. Instead of trying to preserve fresh produce, processing converts it into shelf-stable forms (canned tomatoes, dried fruit, frozen vegetables, tomato paste, flour, ingredient products) that can be stored and transported without the constraints of the cold chain. African processing capacity varies by crop and country. Some categories, notably palm oil, cocoa, and coffee, have meaningful processing infrastructure. Others, including fresh tomato processing, fruit processing, and dairy processing, are underdeveloped relative to the scale of raw production.
Releaf, the Nigerian agri-processing company, has built its business around the processing-to-reduce-loss logic. The company's Kraken processing system is designed to produce 100 tonnes per day of palm oil, approximately 200 times faster than a smallholder farmer using traditional manual methods. By building industrial processing capacity close to smallholder farms, Releaf reduces the need for long-distance transport of raw palm fruit (which is heavy, bulky, and perishable) while extracting more value from the underlying production. This is a fundamentally different logic from fresh-produce logistics and points toward a more industrial future for African agriculture as processing capacity scales.
Three indicators will determine whether the post-harvest loss situation improves. First, whether operators building cold storage infrastructure can achieve unit economics that justify expansion beyond current footprints. Solar-powered approaches like ColdHubs reduce operating costs but still require substantial upfront capital investment. Second, whether processing investment scales in the categories (tomatoes, fruits, dairy) where it has historically been weakest. Third, whether infrastructure investments (rural roads, electricity grid extension, market facilities) keep pace with the commercial logistics improvements that private operators can make. Private sector operators can reduce losses within their own supply chains, but they cannot fix the underlying infrastructure failures that make the broader market inefficient. The post-harvest loss story is a public good as much as a commercial opportunity, and sustained improvement requires both components.
