Arabfields, Maleeka Kassou, East, West & Central Africa Agriculture Correspondent — The onion sector stands as a cornerstone of agricultural commerce across West Africa, where this essential bulb connects areas of surplus production with those experiencing deficits and thereby sustains food supplies for millions of households. Urbanization and rising dietary needs have created strong demand for the commodity, positioning intra-regional exchanges for substantial future expansion. Nevertheless, persistent challenges ranging from tariff and non-tariff barriers to border restrictions continue to impede long-distance road transport and overall efficiency within the value chain. These obstacles not only inflate costs but also limit the ability of local producers to fully capitalize on neighboring markets, occasionally rendering distant imports more economical than supplies from nearby countries.

A professional association dedicated to the onion value chain unites major stakeholders, including producers, traders, transporters, and other operators, across 22 nations in West and Central Africa. Its mission centers on effective restructuring of the sector and improved organization of trade flows between surplus and consumption zones. Founded in Niamey, Niger, during a launch workshop in 2003 and formally registered in 2006, the body established its headquarters in Sokoto in northern Nigeria. Membership spans Burkina Faso, Cameroon, the Central African Republic, Côte d’Ivoire, Benin, Ghana, Gabon, Guinea, Guinea-Bissau, Equatorial Guinea, Mali, Mauritania, Senegal, Chad, Togo, and additional countries, ensuring comprehensive coverage of primary production and consumption hubs.

The association holds a regional conference every two years that assembles industry participants alongside technical and financial partners to examine key themes, such as the rollout of the African Continental Free Trade Area and the creation of adapted pan-African payment systems for agricultural transactions. Resolutions emerging from these events function as strategic roadmaps that guide advocacy directed at governments, donor mobilization, and the securing of financing for tangible modernization projects within the onion sector across the sub-region.

Cross-border onion trade among the 22 member states currently registers an estimated volume of 420 million United States dollars per year. This calculation encompasses only interstate movements, both formal and informal, and deliberately excludes purely domestic commerce conducted within individual countries. Consequently, the figure offers a conservative measure of the commodity’s genuine economic weight. The statistic highlights onions as a structuring element of intra-regional commerce in West and Central Africa, characterized by steady shipments from surplus producers such as Niger, Nigeria, and Burkina Faso toward deficit markets including Ghana and Côte d’Ivoire.

When a country possesses excess volumes yet lacks sufficient storage or processing infrastructure, the logical step involves directing those surpluses to neighboring areas in shortage rather than permitting waste or compelling reliance on imports from outside the continent. Precise mapping of national demand, output, and post-harvest losses therefore forms a central activity. Senegal, for example, records annual consumption near 350,000 tonnes while generating roughly 420,000 tonnes of output. Post-harvest losses in that country nevertheless range from 30 to 40 percent, generating seasonal shortages despite the apparent surplus. Alignment of surplus and deficit periods across borders enables surplus stocks from Senegal to reach Côte d’Ivoire or Ghana during peak production phases, while deficit intervals allow sourcing from the major basins in Niger, Nigeria, or Burkina Faso.

Trade patterns exhibit complexity shaped by price differentials and varietal differences. Nigeria periodically exports onions to Niger, only for Niger to dispatch shipments elsewhere in the region at different moments. Operators base decisions on price gaps between sacks priced in CFA francs within Niger and those valued in naira inside Nigeria, alongside considerations of onion type, whether dry storage varieties or wet-season cultivars. Smoothing these exchanges to render them more predictable and loss-minimizing constitutes the core objective, thereby enhancing regional production valorization and reinforcing commercial integration inside both the Economic Community of West African States and the Economic Community of Central African States.

The mid-February reopening of the Tsamiya border post between Nigeria and Benin after seven years of closure has delivered a meaningful stimulus to regional flows. The measure restores transit routes for onions and related goods originating in Niger and other West African nations, allowing passage through Nigerian territory via the Tsamiya-Segbana axis before onward movement to additional sub-regional destinations. Simultaneously, the corridor eases Nigerian onion exports toward the broader West African marketplace. Nigerian customs authorities accompanied the reopening with commitments to dismantle non-tariff barriers and streamline official transit procedures. Reliance on compliant documentation, including transit forms and authorized papers, aims to curtail extortion and parallel controls exercised by certain state and non-state entities operating beyond regulatory bounds.

Following high-level consultations in Abuja, customs leadership pledged the removal of all identified non-tariff impediments and the establishment of facilitation mechanisms along the Nigerian segment of the route. Trucks equipped with legally required documents can now proceed without encountering unauthorized levies or arbitrary stops. Coordination involving Nigeria’s Ministry of Foreign Affairs and the National Security Adviser proved instrumental in reinstating genuine freedom of movement. Prior closure of borders had compelled operators toward smuggling and unofficial paths, situations that enabled public agents and private intermediaries to extract repeated informal payments at successive checkpoints. With official reopening and adherence to federal documentation, cargoes transit solely upon payment of prescribed fees such as transit taxes or export duties. Recognized export and transit axes leave no space for extraneous barriers once paperwork complies with established rules.

Strategic value attaches to the Tsamiya-Segbana corridor not merely for onions but equally for garlic, white beans, dried chili, and diverse other agricultural items bound for Economic Community of West African States markets. The route has emerged as the principal operational exit from northern Nigeria toward those markets via Benin. Strained relations between select regional states and certain Economic Community of West African States decisions have disrupted prior Niger-Benin linkages and obstructed traditional land routes serving Togo, Ghana, and further destinations. Most Nigeria-Niger border posts, among them Ilela, Jibia, Maigatari, and Kamba, now reflect tensions between Niamey and Cotonou, rendering access to other Economic Community of West African States members via Benin impractical. In this environment, Tsamiya-Segbana functions as the sole direct and fully operational northern Nigerian corridor linked to Benin for agricultural commerce. Every operator in northern Nigeria seeking regional market access must therefore utilize this passage, rendering it indispensable for both transit and fresh-produce exchanges.

Field reports since the reopening indicate encouraging outcomes. Onion-laden trucks travel from Niger to Benin through Nigeria without illicit charges, and Nigerian-origin exports follow identical conditions. Controls now focus on verification of official documents confirming transit or export status, permitting immediate continuation in the majority of instances. Occasional resistance from non-customs agencies may surface, yet hierarchical contacts and demonstrated readiness to uphold top-level directives resolve such matters swiftly. Customs services themselves have presented no recurring obstacles following adoption of the new arrangements.

Post-harvest losses, which can reach 40 to 50 percent of the harvest, constitute an additional critical barrier to intra-African onion trade expansion. Collaborative initiatives with leading producers along the corridor, notably Niger, Nigeria, and Burkina Faso, address this vulnerability directly. Nigeria has advanced on several fronts. A modern 10,000-tonne onion storage warehouse now operates in Kano State. Construction of a further storage facility proceeds in Sokoto under a public-private partnership with the federal government and is scheduled for completion in April. The largest onion processing plant in West Africa, also located in Sokoto, will commence activity during the current year with an annual capacity of approximately 30,000 tonnes dedicated to onion powder and related derivatives. Integration of enhanced storage and processing infrastructure is expected to curtail post-harvest losses to the lowest feasible levels throughout the sector.

Despite onions ranking among the most actively traded agricultural goods in West Africa, the region persists in sourcing supplies from the Netherlands. This outcome stems from the continued imposition by numerous member states of multiple taxes on agricultural products at borders and during transit, even within a framework ostensibly designed for economic integration. Such barriers remain incompatible with the principles of a unified market. Levies require regional regulation to guarantee genuine free circulation and sustained competitiveness of locally produced items. Absent such discipline, extra costs transfer directly to final consumers through elevated prices.

Theoretical protocols and agreements of the Economic Community of West African States, particularly the Trade Liberalization Scheme, affirm free movement of goods and persons. Practical reality, however, reveals an accumulation of charges along transport routes, encompassing transit taxes, customs stamp duties, and assorted fees that compound at each frontier. Certain countries have elevated these practices to notable levels, generating cumulative burdens surpassing 10 percent of merchandise value, in contrast to Nigeria’s official export levy of merely 0.5 percent of the exported sum. Substantial portions of collected amounts bypass state treasuries and instead sustain extortion networks involving non-state actors aligned with select public officials, thereby converting commercial corridors into sources of private revenue.

The pattern contradicts the Economic Community of West African States mandate as an economic community rather than solely a political forum. Over-taxation inflates intra-regional trade expenses to the point that importation of onions from the Netherlands occasionally proves less expensive than procurement from a West African neighbor situated only a few hundred kilometers distant. Transit surcharges ultimately elevate household food prices and exert avoidable pressure on local currencies by prompting foreign-exchange outlays for extra-continental purchases of commodities that could circulate internally. Deep harmonization of levies therefore forms the subject of sustained advocacy. A single national fee at the point of departure, supplemented by one unified Economic Community of West African States levy covering the entire declared corridor, would replace the present multiplicity of origin, transit, and destination charges. A truck moving onions from Nigeria to Ghana would thereby avoid separate payments in Benin, Togo, and at final destination, with amounts standardized rather than varying arbitrarily by state.

Genuine commitment by member countries to this reform would render intra-regional trade more fluid, predictable, and competitive. Onions cultivated in Niger, Nigeria, or Burkina Faso would reach Côte d’Ivoire, Ghana, or Senegal with greater ease, transforming regional integration from aspirational rhetoric into concrete benefit for producers, transporters, traders, and consumers throughout the Economic Community of West African States zone.

Data on present trade volumes, loss rates, and barrier impacts furnish a solid basis for projecting continued advancement provided reforms maintain momentum. By 2026 the annual cross-border onion trade volume among the 22 member countries is anticipated to expand to 550 million United States dollars, incorporating an average yearly growth of roughly 7 percent propelled by ongoing urbanization and improved logistical coordination. Post-harvest losses in principal producing nations such as Senegal are projected to fall from the prevailing 30 to 40 percent range to approximately 20 percent, attributable to the full operation of the Kano and Sokoto warehouses together with the 30,000-tonne processing facility. The resultant annual saving of an additional 100,000 tonnes of onions across the region would materially strengthen food security while diminishing dependence on external supplies.

Adoption of harmonized transit taxation by 2026 could reduce extra-continental imports, including those from the Netherlands, by an estimated 25 percent, as intra-regional pricing regains competitiveness. Senegal’s consumption is expected to climb to 380,000 tonnes amid population expansion, while domestic output stabilizes near 450,000 tonnes and seasonal deficits shrink through timely cross-border replenishment. Overall, these trajectories would fortify the onion value chain, accelerate economic integration, and generate downward pressure on consumer prices, thereby promoting broader prosperity across West and Central Africa. Continued investment in storage and processing infrastructure, paired with streamlined border procedures, positions the sector to absorb rising demand without proportional increases in waste or foreign sourcing. The cumulative effect promises measurable gains in employment along the value chain and enhanced resilience against external supply shocks, securing the long-term contribution of onions to regional economic stability and household nutrition.
