Africa's richest man spent $20 million trying to fix Nigeria's tomato problem and the country let him down

Aliko Dangote saw the problem clearly. Nigeria was spending hundreds of millions of dollars every year importing tomato paste from China, much of it adulterated with starch and flour and containing as little as 10 percent actual tomato. Meanwhile, Nigerian farmers in Kano and across the north were producing some of the finest tomatoes in West Africa, most of which rotted in the open air before anyone could do anything useful with them. The solution seemed obvious: build a factory, buy the tomatoes, process the paste domestically, and keep the money inside Nigeria.

In March 2016, he did exactly that. Dangote launched the Dangote Tomato Processing Factory at Kadawa in Kura Local Government Area, Kano State, with a $20 million investment. The facility was designed to process 1,200 metric tonnes of fresh tomatoes per day, converting them into 200 metric tonnes of paste. It was the largest tomato processing factory in Nigeria and, at the time of its commissioning, one of the largest on the African continent. Dangote announced a guaranteed purchase price for local farmers, set out an agreement to source exclusively from Kadawa Valley growers, and framed the entire project as a blueprint for how African industry could substitute imports with domestic production.

Within a year and a half, the factory had shut down.

A supply chain that did not exist

The first blow came from nature. In the same year the factory launched, Tuta absoluta, an invasive leaf-mining moth originating from South America that attacks both the fruit and foliage of tomato plants, swept through farms across Kano, Kaduna, Katsina, Jigawa and Plateau states. Farmers lost an estimated N2 billion. Entire plots worth millions of naira in production costs were destroyed in single infestations. Hundreds of growers abandoned tomato cultivation entirely and switched to crops that did not carry the same biological risk. The raw material supply on which the Kadawa factory depended evaporated almost overnight.

The factory's managing director Abdulkareem Kaita was candid about what the pest revealed. The plant needed 40 truckloads of fresh tomatoes every single day, each carrying 30 tonnes, to run at its designed capacity. When the pest hit, that supply simply did not exist. Nigeria had built the processing factory. It had not built the agricultural infrastructure to feed it.

The factory sat idle from late 2017 through early 2019. Dangote's team used those two years to negotiate new pricing arrangements with farmers, work with agricultural bodies on pest management protocols and set a production restart for March 2019 to align with the harvest season. It was the kind of patient, methodical institutional problem-solving that most companies would not attempt after an initial failure of that scale.

The March 2019 restart worked. Briefly. By September of that year, barely six months after reopening, the factory had shut down again. This time the cause was not a pest but the agricultural calendar itself. Farmers engaged to supply the factory abandoned tomato cultivation at the start of the rainy season, switching to other crops with more predictable returns. The factory required a consistent, year-round supply that the seasonal structure of Nigerian small-scale tomato farming could not provide. Kaita told reporters at the time that the company was losing at least N30 million every month the plant remained closed.

The price war it could not win

The deeper problem, the one that has kept the Kadawa factory dormant from 2019 to the present, is one that no amount of farmer negotiation or seasonal timing can solve on its own.

Chinese-imported tomato paste was arriving in Nigerian markets at prices that made locally produced paste commercially impossible. The imports were not competing on quality. Products containing as little as 10 percent tomato content, padded with starch, flour and other fillers, were being sold at prices far below what Dangote's factory could charge for a product made from 100 percent fresh Nigerian tomatoes. The price of energy required to run the processing facility, the cost of sourcing fresh tomatoes at prices that kept farmers in the business, and the overhead of operating Nigeria's largest processing plant could not be recovered when the market price was being set by a product that barely contained tomatoes.

Import bans helped on paper. Enforcement in practice was a different story. Smuggling continued. Substandard paste kept moving through informal channels and into the distribution system. A factory built to produce a superior product at a competitive price found itself unable to compete with a category of imports that should not have been on the shelves in the first place.

By 2025, a BusinessDay investigation confirmed the factory had been shut for four years. Kaita, speaking as the former managing director, described the situation with the kind of specificity that comes from watching a commercially sound idea fail due to factors entirely outside the investor's control. The high cost of energy, the impossibility of competing with adulterated imports, the structural absence of a reliable raw material supply chain. These were not failures of execution inside the Kadawa plant. They were failures of Nigerian agricultural and trade policy architecture that predated Dangote's investment by decades.

What the factory actually needed

The Kadawa plant required things that $20 million cannot buy. It needed a cold chain storage network across Kano and the surrounding tomato-growing states, so that the inevitable seasonal glut could be held rather than wasted. It needed consistent, properly funded pest management infrastructure capable of responding to outbreaks like the 2016 Tuta absoluta infestation before they wiped out entire farming seasons. It needed enforced import quality standards that actually kept adulterated paste off shelves. It needed farmer financing mechanisms to sustain tomato cultivation through the seasons and price cycles when competing crops looked more attractive. It needed road infrastructure capable of moving 40 truckloads of perishable produce daily from remote farming communities to a processing facility without the fruit deteriorating in transit.

None of those things existed in 2016. Most of them do not exist in 2026. Nigeria spends over $400 million a year importing tomato paste, according to the Nigerian Export Promotion Council, despite being the second-largest tomato producer in Africa.

The Nigerian Stored Products Research Institute's senior research officer Adamu Ahmad Abubakar identified the same gaps in June 2026, telling reporters that poor road networks, lack of cold-chain storage, weak processing systems and limited access to funding remain the principal reasons tomatoes continue to rot before they can be used. These are the same gaps that defeated Dangote's factory a decade ago.

The chilling effect

What makes the Kadawa story significant beyond Dangote's own balance sheet is what it communicated to every other potential investor in Nigerian food processing. If Africa's richest man, with $20 million in capital, direct government relationships, the capacity to absorb multi-year losses and a management team capable of executing a restart after a two-year shutdown, still could not make a tomato processing plant work in Nigeria's most productive tomato region, the signal to smaller investors was unambiguous. No comparable private player has moved to fill the gap since the Kadawa factory went quiet.

Dangote's intervention was not a business failure. It was an exposure. The factory ran as well as the ecosystem allowed it to. When the ecosystem failed, as it did repeatedly and for reasons that were largely beyond any private investor's control, the factory had no choice but to stop.

The Kadawa plant now sits dormant in Kura Local Government Area, its rusting infrastructure a monument not to Dangote's limitations but to the infrastructure deficit that has defined Nigerian agriculture since before he was born. The $400 million Nigeria spends annually on imported tomato paste is the price tag on that deficit. Dangote tried to pay it down ten years ago. The country has not yet built what his factory needed to succeed.
