What's the connection between roads and conflict in West Africa? This may seem like an odd question. But a we conducted shows a close relationship between the two.

We are researchers of transnational political violence. We analyzed 58,000 violent events in West Africa between 2000 to 2024. Our focus was on in relation to transport infrastructure.

Anecdotal evidence suggests that roads, bridges, pipelines and other transport systems are across West Africa, but little is known about the factors that explain when, where and by whom.

Violence in West Africa involves a complex mix of political, economic and social factors. Weak governance, corruption, urban-rural inequalities and marginalized populations have been exploited by numerous armed groups, including transnational criminal networks and religious extremists.

West Africa has been one of the world's most violent regions since the mid 2010s. In 2024 alone, the initiative recorded over 10,600 events of political violence in the region. These ranged from battles between armed groups, explosions and other forms of remote violence, to attacks on unarmed civilians. An estimated 25,600 people were killed. This has been the status quo in the region for nearly a decade.

The results of our study show that 65% of all the attacks, explosions, and violence against civilians recorded between 2000 and 2024 were located within one kilometer of a road.

Only 4% of all events were located further than 10km from a road. This pattern was consistent across all road types but most pronounced near highways and primary roads.

We think the reason for this pattern is that there is fierce competition between state and non-state actors for access to and use of roads.

Governments need well-developed road networks for a host of reasons, including the ability to govern, enabling economic activity, and security. Roads enable military mobility and reduce potential safe havens for insurgents in remote regions.

Insurgent groups also see transport networks as prime targets. They create opportunities to blockade cities, ambush convoys, kidnap travelers, employ landmines, and destroy key infrastructure.

Our research is part of a long line of work that explored the role of infrastructure in relation to security in West Africa. Our latest research reinforces earlier findings linking the two. Transport networks have become battlegrounds for extremist groups seeking to destabilize states, isolate communities and expand their influence.

The network

The West African road network is vast, at over 709,000km of roads by the Global Roads Inventory Project. It compares unfavorably with other African regions. For example, paved roads remain in West Africa (17% of the regional network) when compared with North Africa (83%).

Poorly maintained roads impose costs on West African countries. They increase transport time of perishable goods, shorten the operational life of trucks, cause more accidents, and reduce social interactions between communities.

Still, significant variations in road quality are found across the region. The percentage of paved roads ranges from a high of 37% in Senegal to just over 7% in Mali. Nigeria has the in West Africa with an estimated 195,000km, but much of it has deteriorated because of poor maintenance.

Road-related violence is on the rise

We found that road-related attacks have been on the rise since jihadist groups emerged in the mid-2010s. Only 31 ambushes against convoys were reported in Burkina Faso, Chad, Mali and Niger from 2000 to 2015, against 497 from 2016 to 2023.

Attacks frequently occur along the same road segments, such as around in the Gourma Mounts, where (JNIM) conducted nine attacks against Malian forces and Wagner mercenaries between 2019 and 2024.

Violence was the most clustered near roads in 2011, with 87% of all violent events located within 1km of a road. Our analysis shows that, though still high, there's been a decline post-2000: 59% in 2022 and 60% in 2024. This evolution reflects the in West Africa. As jihadist insurgents target rural areas and small towns more and more, an increasing share of violent events also occurs far away from roads.

We've studied the root causes of West Africa's violence for nearly a decade, documenting the ever-intensifying costs paid by its people. In the process, we've uncovered overlooked aspects of the turmoil, including the centrality of the road networks to an understanding of where the violence is happening.

The most dangerous roads of West Africa

Our findings show that violence against transport infrastructure is very unevenly distributed in West Africa and that specific road segments have been repeatedly targeted. This was particularly the case in the Central Sahel, Lake Chad basin, and western Cameroon.

For example, the 350km ring road linking in Cameroon is the most violent road in West Africa, with 757 events since 2018, between the government and the Ambazonian separatists.

The longest segments of dangerous roads are in Nigeria, particularly those connecting Maiduguri in Borno State to Damaturu, Potiskum, Biu and Bama.

In the Central Sahel, the road between Mopti/Sévaré and Gao is by far the most violent transport axis, with since the beginning of the civil war in Mali in 2012. South of Gao, National Road 17 leading to the Nigerien border, and National Road 20 heading east toward Ménaka have experienced respectively, since the Islamic State—Sahel Province (ISSP) its activities in the region in 2017.

In Burkina Faso, all the roads leading to near the border with Mali have experienced high levels of violence since the early 2020s.

Building transport infrastructure to promote peace

Roads are an important part of state counterinsurgency strategies and a strategic target for local militants. Yes, as our work highlights, transport infrastructure is largely ignored in debates that emphasize more state interventions as a means of combating insecurity. Sixty years after the independence of many West African countries, remains elusive in the region.

Peripheral cities such as Bardaï, Bilma, Kidal and Timbuktu, where rebel movements have historically developed, are still not connected to the national network by tarmac roads.

The duality of the transport infrastructure, as both a facilitator and target of violence, has put government forces at a disadvantage. Regular forces are heavily constrained by the sparsity and poor conditions of the road network, which makes them vulnerable to attacks without necessarily allowing them to project their military power over long distances.

Rather than building transport infrastructure, states have focused on by investing in military bases. The military coups in Burkina Faso, Mali and Niger have further reinforced this trend, with the creation of a joint force by the countries of the Alliance of Sahel States.

Strengthening security has taken precedence over developmental support for peripheral communities, who experience the worst of the violence.
