The United Nations ended its decade‑long peacekeeping mission in Mali in June 2023, completing the withdrawal by year’s end. The operation, known as MINUSMA, had been the organization’s most visible presence in the Sahel since its creation by the Security Council in 2013. Its departure marked the close of a chapter in which UN troops provided security and political support across the region.

Although the uniformed mission ceased, the UN’s engagement did not stop. The UN Office for West Africa and the Sahel (UNOWAS) continued to operate as a political mission, while the broader UN system maintained humanitarian and development activities. The shift reflects a change in the operating environment, driven by recent moves among three Sahelian states.

In January 2025, Burkina Faso, Mali and Niger formally left the Economic Community of West African States (ECOWAS). The same trio later formed the Alliance of Sahel States (AES), emphasizing sovereignty and strategic autonomy as central goals. Their exit altered regional structures that had previously coordinated political and security responses, leaving ECOWAS and other bodies to navigate a more fragmented landscape.

Humanitarian conditions remain volatile. Displacement, insecurity, food shortages and climate‑related stresses continue to affect populations across borders, even as national governments assert greater control over their own security policies. The UN now operates in a context where traditional peacekeeping tools are limited and where regional alliances are reshaping security dynamics.

Analysts note that the UN’s leverage has narrowed. Mubarak Aliyu, a security analyst based in Nigeria, observed that the AES states have removed mechanisms that once gave external actors influence, replacing them with their own confederation and joint forces. “The influence the UN can actually exercise is narrow,” he said.

In February 2026, the Security Council extended UNOWAS’s mandate until January 31, 2029, while ordering an independent strategic review to be completed by September 30, 2026. The review comes as West Africa’s political terrain is being reshaped by military governments, new regional partnerships and a heightened focus on national sovereignty. Russia’s growing role in the region adds another layer of complexity; its Africa Corps has supported Mali and Niger’s military administrations in ways that the UN was not equipped to address, primarily as regime protection rather than counterinsurgency.

Kabir Adamu, founder of a security consultancy in Abuja, argues that the UN should pivot away from large troop deployments toward diplomatic and development‑focused solutions. “Looking ahead, the UN’s priorities in the Sahel should promote effective security sector governance and reform,” he said. “This will mean shifting from traditional, large‑scale peacekeeping to deeper preventive strategies that address the root causes of fragility, conflict and violence.”

The fragmented security architecture suggests that the UN should work through existing regional mechanisms rather than create its own forces. Adamu recommends that the organization prioritize inclusive mediation to bridge divides between Sahelian and coastal states, while supporting alternative frameworks such as the Multinational Joint Task Force and the Accra Initiative.

Problems in the Sahel have not disappeared with the withdrawal of peacekeepers. Displacement, armed violence, organized crime, food insecurity and climate pressures continue to intersect, especially where state institutions remain weak. Climate change does not single‑handedly cause instability, but environmental and economic stresses can exacerbate vulnerabilities in already fragile communities.

Humanitarian work remains a key avenue for UN involvement. The organization continues to facilitate dialogue, support aid operations and raise awareness of regional crises, even when host governments reject large‑scale military interventions. Emphasis is placed on strengthening local and regional capacities, integrating climate‑peace initiatives and ensuring that assistance is flexible and locally owned.

The 81st session of the United Nations General Assembly convened on September 8, 2026, with its general debate scheduled to begin on September 22. The session takes place without a UN peacekeeping mission in Mali and with Burkina Faso, Mali and Niger outside ECOWAS, while the AES operates as a separate political framework. Observers say this context positions the UN more as an advocate and service provider than as a decisive shaper of outcomes. “It can report, brief, fund aid operations and press for access, but it cannot compel it or offer the regime security that has made Russia indispensable to the military governments,” Aliyu noted.

In the evolving regional environment, the UN’s influence is likely to be exercised through diplomacy, access and partnerships rather than through a substantial military presence. Its ability to affect outcomes will depend on how effectively it can navigate the new political realities and support humanitarian and development efforts amid persistent instability.
