Africa’s Top Onion Producers: Which Countries Dominate the Continent’s Most Essential Crop?
Onions are quietly one of Africa’s most strategically important vegetables — grown from the Nile Delta to the Sahel, traded across borders, and eaten in virtually every cuisine on the continent. In 2022, Africa produced tens of millions of tonnes of Allium cepa, with a handful of nations responsible for the overwhelming majority of that output. The rankings reveal a continent of sharp agricultural contrasts: ancient irrigation systems, semi-arid microclimates, and modern agribusiness all playing a role in who grows the most.
Egypt and North Africa Dominate the Rankings
Egypt sits at the top of Africa’s onion production table by a considerable margin, harvesting 3,663,943 tonnes in 2022 according to FAO data. That figure is more than double the output of the second-ranked country and reflects centuries of agricultural refinement along the Nile Delta, where rich alluvial soils and year-round irrigation create near-ideal growing conditions. Egypt is also a significant onion exporter, shipping large volumes to markets across the Middle East and Europe, particularly through the port of Alexandria. The country cultivates multiple varieties, including the prized Giza Red onion, which is well adapted to the dry heat of Upper Egypt.
Algeria ranked second on the continent with 1,763,118 tonnes in 2022, a figure that reflects decades of state investment in expanding irrigated farmland across the northern Tell region and parts of the High Plateaus. Morocco followed at sixth place overall with 802,389 tonnes, benefiting from its Atlantic coastal plains and the Souss-Massa region, where drip irrigation technology has become increasingly widespread. Together, North African nations account for well over half of the continent’s total onion output — a dominance driven by climate, infrastructure, and proximity to export markets.
The Nile and Sahel Belt: Sudan and Niger
Sudan produced 1,591,709 tonnes of onions in 2022, placing it third in Africa. The country’s production is heavily concentrated along the Nile corridor and in the Gezira scheme — one of the world’s largest irrigation projects — where controlled water flow allows farmers to grow onions during the dry season when market prices are highest. Sudanese onions are a major commodity in regional trade, moving into Chad, Ethiopia, and South Sudan through informal cross-border networks that rarely appear in official export statistics.
Niger, ranked fifth with 1,496,545 tonnes, is arguably the most remarkable story in African onion production. Despite being one of the world’s least developed economies and a landlocked Sahelian nation with erratic rainfall, Niger has cultivated a globally recognized onion variety — the Violet de Galmi — that commands premium prices in West African markets and has even attracted interest from European importers. Production is concentrated around the Tahoua and Agadez regions, where shallow water tables allow smallholder farmers to irrigate using simple rope-and-bucket systems. The Violet de Galmi’s distinctive flavor and long shelf life make it especially valuable for long-distance trade.
West Africa’s Growing Weight: Nigeria and Senegal
Nigeria produced 1,554,966 tonnes in 2022, ranking fourth on the continent and first in sub-Saharan Africa. The country’s onion belt runs through the northern states of Kebbi, Sokoto, and Katsina, where the dry harmattan season creates conditions well suited to onion curing and storage. Onions are a critical cash crop for millions of smallholder farmers in these states, and the commodity is central to the trade economy of Sokoto’s famous onion markets, which distribute produce as far south as Lagos and across borders into Benin and Ghana.
Senegal’s 420,000-tonne harvest in 2022 may appear modest by comparison, but it represents a significant policy achievement. The Senegalese government has invested heavily in the Casamance and the Niayes coastal zone to reduce the country’s historically high dependence on onion imports from the Netherlands and Europe. Seasonal import bans, introduced to protect local farmers during the domestic harvest window, have gradually shifted market dynamics in favor of Senegalese producers — though supply chain losses due to poor cold storage infrastructure remain a persistent challenge.
Southern and Central Africa: Steady but Developing
South Africa produced 678,544 tonnes in 2022, with the Western Cape and Northern Cape provinces accounting for the bulk of commercial output. The country’s onion sector is among the most technically advanced on the continent, with large-scale mechanized farms supplying major retail chains and a growing export trade to neighboring SADC countries. Mozambique (409,742 tonnes) and Cameroon (386,766 tonnes) round out the top ten, both representing frontier markets where onion cultivation is expanding but still largely dependent on smallholder production with limited access to certified seed varieties, cold chain logistics, or formal market linkages.
What the Rankings Tell Us About African Agriculture
Africa’s onion production map is ultimately a map of water access, infrastructure investment, and agricultural policy. The countries at the top — Egypt, Algeria, Sudan — share reliable irrigation systems and decades of institutional support for farming. The outliers, like Niger, show what smallholder ingenuity and a well-adapted crop variety can achieve even under severe resource constraints. As climate pressures intensify and urban food demand across African cities continues to rise, onion production will remain a bellwether for the continent’s broader agricultural resilience — and the gaps between these ten countries will be worth watching closely in the years ahead.
