Main drivers of conflict in the African Sahel

The African Sahel, a transitional region between the Sahara Desert to the north and the Sudanian savanna to the south, stretches across the continent from Senegal in the west to Chad and Sudan in the east. Despite its rich history and cultural diversity, the Sahel has become synonymous with instability and recurrent conflict. Understanding the underlying reasons for this challenging environment requires a deep dive into historical, socioeconomic, environmental, and political dynamics unique to the region.

Historical Context and Colonial Legacies

Historical patterns of governance, beginning with pre-colonial empires like the Mali and Songhai, contributed to the region’s complex ethnic and cultural landscape. The colonial carve-up of Africa by European powers in the late nineteenth and early twentieth centuries disregarded existing social and ethnic boundaries, creating artificial borders that persist today. As a result, ethnic groups were divided across new national lines—Tuaregs, Fulani, Hausa, and others found themselves citizens of different states overnight. This arbitrary partition contributed to lasting grievances, contested identities, and a foundation of mistrust between communities and the post-independence states in the Sahel.

The colonial legacy also established centralized, often unresponsive governance structures. Many Sahelian states inherited patrimonial systems focused on urban elites, neglecting peripheral, rural regions. This unequal power distribution has fueled a sense of marginalization among rural groups, setting the stage for resistance and, at times, violent rebellion.

Socioeconomic Challenges and Lack of Development

Poverty rates in the Sahel consistently rank among the highest globally. According to the United Nations Development Programme, countries like Niger, Mali, and Burkina Faso feature in the lowest deciles on the Human Development Index. Widespread unemployment, lack of access to quality education, limited healthcare, and food insecurity create fertile ground for vulnerability and social unrest.

A study in the Lake Chad Basin illustrates how an economic downturn can fuel conflict. In the past, Lake Chad was a vital resource for millions, offering fishing, farming, and commerce opportunities. However, as a result of climate change and excessive exploitation, the lake’s size has decreased by over 90% in the past six decades. With the loss of livelihoods, local populations encountered heightened rivalry for dwindling resources, which spurred community conflicts and created a conducive environment for extremist groups to recruit.

Those social and economic challenges intersect with population patterns: the Sahel is home to one of the fastest-expanding populations globally, increasing pressure on already limited resources and governmental abilities. The swift movement towards cities and the surge in youth—the average age in Niger is below 16—result in millions of young individuals seeing limited opportunities, escalating the chance of becoming radicalized or engaging in unlawful economic activities.

Environmental Issues and Alterations in Climate

The Sahel is particularly sensitive to shifts in climate. The area is defined by delicate soils and unpredictable rain patterns. Droughts and unusual weather events are increasingly frequent and intense. Livestock herders, like the Fulani, who rely on moving their animals according to the seasons, must journey greater distances to find water and grazing areas. This results in rising conflicts with settled farmers, as established grazing paths intersect with cultivated lands. These clashes between farmers and herders are a frequent cause of violence, often intensified during times of shortage.

Climate change exacerbates existing governance and economic issues, transforming manageable tensions into possible points of conflict. The United Nations Environment Programme has recognized the Sahel as a “climate change hotspot,” where the combination of environmental and social vulnerability is especially noticeable.

Fragile Government Entities and Governance Shortcomings

States in the Sahel frequently lack the capacity to provide basic services, enforce the rule of law, or maintain a monopoly on the legitimate use of force. Remote areas are often left with little presence of central authority, allowing ungoverned spaces to proliferate. This institutional vacuum is readily filled by non-state actors, including armed militias, self-defense groups, criminal syndicates, and insurgent movements.

Deficiencies in governance create a widespread feeling of marginalization, especially among ethnic minorities and rural communities. Issues concerning land ownership, distribution of resources, and political representation frequently remain unresolved through formal processes, prompting dissatisfied groups to address matters independently. Corruption and favoritism further erode trust in government institutions, complicating initiatives for state development and conflict resolution. Moreover, rebel groups often present themselves as providers of stability and justice in regions with limited state presence, making it harder to reestablish governmental control.

The Spread of Armed Groups and Violent Extremism

The Sahel’s instability has enabled the rise of a constellation of armed groups, some with local grievances, others with transnational jihadist agendas. Groups such as Jama’at Nasr al-Islam wal Muslimin (JNIM), Islamic State in the Greater Sahara (ISGS), and Boko Haram operate with varying motives and levels of coordination. Many capitalize on local grievances, recruit marginalized youths, and finance their operations through trafficking in drugs, weapons, and people.

The alliance between local conflict actors and transnational terrorist networks is particularly pronounced in the tri-border area of Mali, Niger, and Burkina Faso. Here, groups exploit ethnic rivalries and government weaknesses to entrench themselves. The result is a landscape where violence can be both deeply localized—rooted in dispute over cattle or land—and interconnected with global jihadist narratives.

International military interventions, such as the French-led Operation Barkhane and the United Nations Multidimensional Integrated Stabilization Mission in Mali (MINUSMA), have had mixed results. While some successes have been recorded, these interventions are often criticized for failing to address root causes, focusing narrowly on counterterrorism and security at the expense of political, economic, and social dimensions.

International Interactions and Localized Instability

Porous borders are a characteristic element of the Sahel region. Individuals, merchandise, and militant factions traverse with relative freedom through lightly regulated boundaries. This movement across borders implies that unrest in one nation can swiftly extend: a coup in Mali, for instance, might encourage insurgents in adjacent Burkina Faso or Niger.

The interconnections between national conflicts have led to spill-over effects. For instance, the 2011 collapse of the Libyan regime unleashed a flood of weapons and displaced fighters into the Sahel, escalating existing disputes and strengthening armed factions. Complex regional dynamics demand cooperative solutions, but geopolitical rivalries and differing priorities among states often hinder effective collaboration.

External Actors and International Interests

The involvement of external actors also shapes the landscape of conflict in the Sahel. France, the former colonial power, maintains a significant military presence and leads counterterrorism operations, motivated by security concerns and the protection of economic interests. The European Union, United States, Russia, and others have backed various stabilization, development, and security initiatives. While international support is critical, competing visions and interests sometimes undermine local ownership and the long-term sustainability of peacebuilding efforts.

Humanitarian organizations encounter significant obstacles when providing assistance in areas of conflict. Their ability to reach those in need is often hampered by safety concerns and bureaucratic barriers, which increase the danger for already vulnerable groups.

Understanding Complexity

Conflicts in the African Sahel are shaped by an intricate blend of historical legacies, social and ethnic divides, economic despair, environmental fragility, and state fragility, all amplified by regional and international dynamics. Solutions that focus solely on security measures or technical development assistance are insufficient without attention to the layers of grievances, identities, and hopes that thread through Sahelian life. Only through recognizing and responding to the full spectrum of these factors can pathways towards stability and renewed opportunity be envisioned for the peoples of the Sahel.
