Boko Haram and ISWAP in Fierce Battle for Control of Borno’s Lake Chad Islands

November 9, 2025

The Lake Chad Basin — once a thriving hub of fishing and agriculture — has again become the center of a deadly power struggle between two rival jihadist groups: Boko Haram and the Islamic State West Africa Province (ISWAP). Their battle for control of the Lake Chad islands in Borno State has intensified, leaving behind destruction, displacement, and renewed fears among residents.

This new phase of conflict underscores the resilience of Nigeria’s insurgency crisis and highlights the complex dynamics at play in one of the country’s most volatile regions. Despite years of military offensives, the insurgents continue to adapt, turning the vast network of islands into their latest battleground.

Renewed Clashes and a Struggle for Dominance

In recent weeks, heavy fighting has erupted between Boko Haram and ISWAP fighters across the Lake Chad islands, particularly around Abadam, Marte, Kukawa, and the Komadugu-Yobe River corridor. These areas are of immense strategic value — serving as gateways for movement, trade, and access to resources that sustain both armed factions.

Security reports indicate that ISWAP launched coordinated offensives aimed at dislodging Boko Haram remnants from the northern islands. Witnesses from nearby communities described scenes of chaos as explosions and gunfire echoed across the lake. Many residents fled their villages under the cover of darkness, seeking refuge in safer areas.

A fisherman from Baga, who escaped the violence, told SaharaNews247, “We heard loud gunfire for hours. The water lit up with flashes. People ran in all directions. Many did not make it out.”

ISWAP, which has maintained a dominant presence in the region since 2021, is reportedly trying to consolidate its control over trade and smuggling routes that link Nigeria to Chad and Niger. Boko Haram, though weakened, remains fiercely resistant, determined to reclaim territories it lost after internal divisions.

Why the Lake Chad Islands Matter

The Lake Chad islands are more than isolated patches of land — they are the economic heart of local survival. For decades, they sustained millions through fishing, farming, and cross-border trade. But for insurgent groups, they offer even greater strategic advantages.

First, the islands provide natural concealment. The maze of waterways, swamps, and vegetation makes it difficult for conventional military forces to navigate or launch sustained operations. Second, the location offers access to three international borders, making it easy for fighters to retreat, regroup, or smuggle supplies across countries with limited border patrols.

Equally important are the economic incentives. Control of the islands means control of lucrative fish markets and taxation systems. ISWAP, in particular, has developed a shadow economy — collecting levies from fishermen, traders, and transporters in exchange for “protection.”

Analysts describe this as a blend of insurgency and organized crime. By controlling both the population and the economy, these groups maintain influence and recruit new fighters. In many cases, locals comply simply to survive.

Boko Haram and ISWAP: From Alliance to Enemies

The ongoing battle is rooted in the ideological split that divided Boko Haram nearly a decade ago. Founded by Mohammed Yusuf and later led by Abubakar Shekau, Boko Haram gained international notoriety for its indiscriminate attacks, mass abductions, and destruction of communities.

In 2016, a faction broke away to form ISWAP, pledging allegiance to the Islamic State (ISIS). This new group adopted a more structured approach, focusing on military and government targets and attempting to win local support through controlled taxation and limited social services.

The rivalry between both factions deepened after Shekau’s death in 2021, when ISWAP fighters invaded his base in Sambisa Forest. Instead of collapsing, Shekau’s loyalists scattered across the region, regrouping under the old Boko Haram identity. Today, the two groups remain locked in a deadly feud for control, influence, and survival.

What makes the Lake Chad islands especially significant is their shared interest in the area’s resources. While ISWAP seeks long-term dominance, Boko Haram is fighting to prove it still matters — a symbolic and tactical struggle that has claimed hundreds of lives on both sides.

Civilians Caught in the Crossfire

Behind the headlines, it is the civilians who pay the highest price. Villages once bustling with fishing activities now lie deserted. Families have been uprooted, and thousands of displaced people continue to arrive at overcrowded camps in Maiduguri, Monguno, and Dikwa.

Aid agencies report that food insecurity is worsening. Farmers and fishermen cannot safely return to their lands or waters. Humanitarian convoys face frequent ambushes, and many areas remain inaccessible due to ongoing clashes.

A relief worker with an international NGO told SaharaNews247, “Every time one group gains control, civilians suffer. ISWAP demands taxes; Boko Haram enforces loyalty through fear. Those caught in between face starvation, abduction, or death.”

The humanitarian implications are devastating. According to UNHCR, more than 2.5 million people across the Lake Chad Basin remain displaced by the insurgency, with many facing chronic shortages of food, clean water, and healthcare.

The Military’s Challenge

Nigeria’s military, supported by the Multinational Joint Task Force (MNJTF), has intensified operations along the Lake Chad axis, conducting airstrikes and ground patrols targeting insurgent camps.

Recent offensives reportedly destroyed several ISWAP strongholds in Tumbun Gini, Arege, and Dogon Chuku, eliminating key commanders. However, the terrain poses serious challenges. The lake’s fluctuating water levels, dense vegetation, and difficult weather conditions make sustained control almost impossible.

Once the army withdraws, insurgents often return, re-establishing their networks. This cat-and-mouse cycle has persisted for years, eroding public confidence in security efforts.

Security expert and retired military officer, Colonel Ibrahim Dogo, explains: “The Lake Chad environment is not like open desert warfare. It requires specialized amphibious capabilities, continuous intelligence, and local cooperation. Without trust from the communities, lasting peace is impossible.”

He emphasizes that while military might is crucial, governance and development must follow closely behind. “People need to see the government, not just the soldiers. Otherwise, the cycle will continue,” he adds.

Environmental Decline and Economic Desperation

Lake Chad’s shrinking size — from over 25,000 square kilometers in the 1960s to less than 2,000 today — has turned the region into a hotspot of environmental and social stress. As the water recedes, competition over resources intensifies, deepening poverty and fueling recruitment by insurgent groups.

The declining fish stock and loss of farmland have pushed many young men toward militant camps, where they are promised income, food, and protection. For both Boko Haram and ISWAP, the lake’s resources are not only a means of survival but also a recruitment tool.

Experts argue that any sustainable peace plan must address the environmental crisis. Reviving irrigation systems, supporting small-scale agriculture, and restoring water levels through the Lake Chad Basin Commission’s Transaqua project could help rebuild livelihoods and reduce dependence on insurgent-controlled economies.

Regional Security and Cross-Border Cooperation

The Lake Chad conflict is not confined to Nigeria. Fighters frequently cross into Chad, Niger, and Cameroon, taking advantage of porous borders and weak coordination among regional forces.

The Multinational Joint Task Force, while effective in certain operations, faces funding constraints and limited intelligence-sharing mechanisms. Strengthening this coalition is vital to prevent militants from exploiting national boundaries as escape routes.

Beyond military cooperation, experts stress the need for joint socio-economic recovery initiatives. Regional development strategies, youth empowerment projects, and deradicalization programs can help reduce the appeal of extremist movements and stabilize border communities.

The Way Forward

The renewed insurgent rivalry in the Lake Chad islands reveals that Nigeria’s battle against terrorism is far from over. It also exposes the limitations of a purely military approach. To truly end the cycle of violence, the government and its regional partners must adopt a comprehensive strategy that integrates:

Sustained military presence and intelligence-led operations

Strengthened regional cooperation under the MNJTF framework

Restoration of local governance and public trust

Economic revitalization and livelihood recovery programs

Investment in environmental restoration and education

Winning the Lake Chad war will not depend solely on defeating insurgents but on rebuilding the lives and economies they have destroyed.

Conclusion

The fierce battle between Boko Haram and ISWAP in the Lake Chad islands marks yet another grim chapter in Nigeria’s prolonged insurgency. The conflict, driven by ideology, greed, and survival, continues to destabilize a region already burdened by poverty and environmental decline.

As the Nigerian government intensifies military operations, it must also confront the underlying social and economic realities that feed extremism. True victory will come not from the barrel of a gun but from the restoration of peace, opportunity, and governance in communities long forgotten by the state.

Until then, the Lake Chad islands remain a haunting symbol of resilience — a place where hope struggles to survive amid the roar of gunfire and the whispers of the displaced.
