The Changing Landscape of Security Threats

For decades, national security and counterterrorism strategies have been built around the assumption that violent extremism stems primarily from ideological, political, or religious motivations. While those drivers remain relevant, a powerful new variable has entered the equation: the accelerating effects of climate change and the consequent scarcity of essential resources. The intersection of environmental stress and human security is no longer a distant, theoretical concern—it is a present-day reality that is reshaping the operational environment for security forces, intelligence agencies, and policymakers alike. To craft effective, forward-looking counterterrorism policy, it is essential to understand how climate-driven disruptions can act as threat multipliers, creating conditions where radicalization can take root and violent groups can thrive.

How Climate Change Directly Affects Security

Climate change does not cause terrorism in a direct, causal sense. Instead, it interacts with existing social, economic, and political vulnerabilities to create a fertile ground for conflict. The mechanisms are well-documented and span multiple domains.

Extreme Weather Events and State Fragility

More frequent and intense droughts, floods, heatwaves, and storms impose severe economic costs and test the capacity of governments to respond. When a state is unable to provide basic services, protect its citizens, or rebuild after a disaster, its legitimacy erodes. Terrorist groups are often quick to fill the governance vacuum, offering alternative forms of justice, assistance, or protection. For example, in the Sahel region of Africa, extreme droughts have devastated pastoral and farming livelihoods, pushing communities into competition for shrinking pastures and water sources. Militant groups such as those affiliated with al-Qaeda and the Islamic State have exploited this desperation, using resource disputes as a recruiting tool and positioning themselves as protectors of local interests. A 2022 IPCC report confirms that climate change is increasing the frequency and intensity of extreme events, with Sub-Saharan Africa and South Asia being particularly vulnerable—regions that already experience significant terrorist activity.

Displacement and Migration

Environmental shocks force millions of people to leave their homes each year. Internal and cross-border migration places immense strain on host communities, infrastructure, and social services. In camps for the displaced or in overcrowded urban slums, grievances can fester. Limited access to employment, education, and justice creates a pool of potential recruits for extremist groups. An analysis by the START Center found that in several African countries, climate-induced migration was positively correlated with the spread of terrorist cells. When displaced populations are marginalized or treated as outsiders, ethnic and sectarian tensions can erupt, further destabilizing already fragile regions.

Economic Instability and Resource Competition

Climate change directly undermines sectors that millions rely on for survival—particularly agriculture, fisheries, and forestry. As harvests fail, food prices spike, and rural incomes collapse. Economic hardship increases the appeal of joining armed groups that can offer a steady salary, social status, or a sense of purpose. In the Lake Chad Basin, the shrinking of Lake Chad by more than 90% since the 1960s has destroyed fishing and farming economies, displacing over 30 million people and creating a vacuum that Boko Haram and the Islamic State West Africa Province (ISWAP) have exploited. UNEP reports that the crisis in the Lake Chad region is a prime example of the climate-security nexus.

Resource Scarcity as a Catalyst for Extremism

While climate change acts as a stressor, resource scarcity is the immediate grievance that extremists leverage. Access to water, arable land, energy, and minerals is fundamental to human survival and dignity. When these resources become scarce, competition intensifies at every level: between households, communities, states, and even across international borders.

Water Conflicts

Water is perhaps the most potent driver of conflict in arid and semi-arid regions. Reduced rainfall and glacial melt disrupt river flows, threatening irrigation and drinking supplies. Transboundary river basins—such as the Nile, Tigris-Euphrates, Indus, and Jordan—are flashpoints where upstream and downstream states clash over allocations. Terrorist groups can exploit these tensions to frame governments as incompetent or complicit in marginalizing certain populations. In Yemen, years of mismanagement and climate-related drought exacerbated an already dire water crisis, which the Houthi movement used to rally support against the recognized government. Competition over water also fuels communal violence that, in turn, creates security vacuums that extremist cells exploit.

Land Degradation and Food Insecurity

Topsoil loss, desertification, and deforestation reduce agricultural productivity. In conflict zones like Somalia and Sudan, competing claims to diminishing plots of arable land have sparked deadly clashes between herders and farmers. Militant groups such as Al-Shabaab have inserted themselves as arbiters in these disputes, building local alliances that grant them safe haven and operational space. Food insecurity and hunger cause profound desperation, and victims may be more willing to support groups that promise to restore their livelihoods—or to punish those they blame for their suffering. The World Food Programme has repeatedly warned that climate shocks push additional millions into acute hunger, directly correlating with increased instability in fragile states.

Energy Scarcity and Economic Marginalization

Access to affordable energy is another vector. Dependence on fossil fuels leaves many countries vulnerable to price shocks and supply disruptions. In regions where the state fails to deliver reliable electricity, local populations may turn to informal markets, corruption, or even smugglers affiliated with militant networks. Moreover, competition for oil and gas resources has long been a driver of civil conflict, from the Niger Delta to Iraq’s disputed territories. These conflicts are intensified when climate change compounds the environmental damage caused by extraction, poisoning water sources and destroying farmland—grievances that insurgents readily exploit.

Integrated Strategies for Counterterrorism in a Changing Climate

Traditional counterterrorism approaches—kinetic operations, intelligence sharing, border security—are necessary but insufficient in the face of climate-driven instability. A comprehensive strategy must address the root causes of vulnerability: environmental degradation, weak governance, economic marginalization, and social fragmentation.

Building Climate Resilience in Vulnerable Communities

Investing in climate adaptation directly reduces the conditions that extremists exploit. Projects that restore degraded land, improve water efficiency, introduce drought-resistant crops, and provide alternative livelihoods can strengthen community resilience. For example, the Great Green Wall initiative in the Sahel aims to restore 100 million hectares of land, improve food security, and create jobs. While primarily an environmental program, its security benefits are significant: by giving people a stake in their future and reducing resource-based conflict, it diminishes the appeal of extremist groups. Counterterrorism agencies should partner with development organizations to prioritize such projects in areas identified as at-risk.

Strengthening Governance and the Rule of Law

Climate adaptation alone is not enough. Governments must demonstrate that they can manage resources fairly and effectively. Corruption and nepotism in distributing aid or allocating land rights often worsen grievances. Transparent, accountable governance is the most powerful antidote to extremist narratives. Donors and international partners should tie counterterrorism assistance to governance reforms, including anti-corruption measures, community policing, and inclusive decision-making processes that give marginalized groups a voice. When people feel represented and believe the state can meet their needs, they are far less likely to support violent alternatives.

Early Warning Systems and Predictive Analytics

Data-driven tools can help forecast where climate stressors and security threats are likely to converge. Satellite monitoring of water levels, vegetation health, and population displacement—combined with socioeconomic data—can identify hotspots before they erupt into violence. The United Nations and several governments already use conflict early warning systems that integrate environmental indicators. Scaling these efforts and linking them to rapid-response mechanisms—both humanitarian and security—could prevent crises from escalating. CSIS tracks the climate-security nexus and recommends embedding environmental analysis into national security planning.

International Cooperation and Multilateral Frameworks

Climate change and resource scarcity cross borders. Shared rivers, aquifers, and ecosystems require joint management. Counterterrorism efforts must therefore move beyond bilateral frameworks to include regional and global cooperation. Existing mechanisms, such as the Lake Chad Basin Commission or the International Conference on the Great Lakes Region, can serve as platforms for integrating climate adaptation into security governance. The UN Security Council has held several debates on climate security, but binding commitments remain weak. Amplifying these discussions and channeling resources toward climate-resilient peacebuilding is essential.

Technology and Innovation as Force Multipliers

Technology offers powerful tools for monitoring, predicting, and mitigating climate-security risks. Remote sensing satellites detect early signs of drought or crop failure; artificial intelligence can model the likely impact of resource shortages on population movements; renewable energy microgrids can provide reliable power to security outposts and communities alike, reducing dependence on long, vulnerable fuel supply lines that are often attacked by insurgents.

Satellite Imagery and Geospatial Analysis

Agencies can use high-resolution satellite data to track desertification, water body changes, and illegal land grabs in near-real time. This intelligence helps predict where resource conflicts might occur, allowing security forces and humanitarian organizations to intervene early. In Somalia, satellite monitoring of water reservoirs has been used to anticipate clashes between pastoralists and farming communities, enabling proactive mediation before violence spirals.

Renewable Energy for Security Infrastructure

Military and police bases in remote, off-grid locations often rely on diesel generators, requiring expensive and dangerous convoy resupply missions. Solar panels and battery storage can cut fuel consumption, reduce logistical vulnerabilities, and lower operational costs. Moreover, installing community-scale renewable energy projects around bases can improve local relations by providing clean electricity to nearby villages, undermining insurgent narratives that the government is indifferent to local suffering.

Data Analytics for Risk Mapping

Machine learning algorithms that ingest climate projections, economic indicators, and historical conflict data can generate risk maps with high spatial and temporal resolution. These maps can guide the allocation of development aid, security patrols, and early warning resources. However, such tools must be used with caution: poor data or biased models could reinforce existing inequities or lead to a militarized response to what are fundamentally development challenges.

Case Studies at the Intersection of Climate and Terrorism

The Sahel: A Spiral of Land Degradation and Violence

Across Burkina Faso, Mali, and Niger, the expansion of the Sahara desert has pushed herders and farmers into increasingly intense competition. Militant groups linked to al-Qaeda and the Islamic State have exploited these tensions, recruiting from both communities by offering arms, money, and protection. The number of conflict-related deaths in the Sahel has skyrocketed, with over 10,000 civilian fatalities in 2022 alone. Climate change is not the sole cause—political marginalization, weak state presence, and arms smuggling also play major roles—but it is a powerful accelerant. International counterterrorism missions, such as the French-led Operation Barkhane (since withdrawn) and the UN peacekeeping mission MINUSMA, struggled to address the root causes because they lacked the mandate and capacity to tackle environmental degradation. The lesson is clear: kinetic operations cannot stabilize a region where the land itself is dying.

Lake Chad Basin: The World’s Most Neglected Crisis

The shrinking of Lake Chad has displaced millions and destroyed traditional livelihoods. Boko Haram and ISWAP flourished in this chaos, using the harsh, ungoverned spaces around the lake as safe havens. The Multinational Joint Task Force (MNJTF) of troop-contributing countries—Nigeria, Niger, Chad, and Cameroon—has conducted military operations, but violence continues. A long-term solution requires rehabilitating the lake ecosystem, investing in alternative economic activities like solar-powered irrigation and fishing, and providing security that allows displaced people to return safely. Without such integration, military gains will be temporary.

Syria: Drought and the Path to Civil War

Although the Syrian civil war was not caused solely by climate change, evidence suggests that a severe drought from 2006 to 2010 devastated rural farming communities, forcing over a million people into urban slums on the outskirts of cities like Aleppo, Hama, and Damascus. This mass displacement put enormous pressure on housing and services, deepened grievances against the Assad regime, and contributed to the social powder keg that erupted in 2011. Extremist groups such as the Islamic State later capitalized on the chaos and the marginalization of Sunni communities. The Syrian case starkly illustrates how environmental stress can interact with political repression and economic mismanagement to produce catastrophic conflict.

Conclusion: A Call for Integrated Policy

Counterterrorism in an era of climate change and resource scarcity demands a fundamental rethinking of assumptions. Security cannot be achieved solely through military means; it must be built on a foundation of environmental stability, resilient livelihoods, and inclusive governance. The nexus between climate stress and extremist violence is neither deterministic nor simple. Many communities facing severe environmental challenges do not turn to terrorism. Yet, where governance is weak, inequalities are sharp, and resources are mismanaged, the risk multiplies.

Policymakers should adopt a “climate-informed counterterrorism” approach that integrates environmental risk assessments into national security planning, invests in adaptation in vulnerable hotspots, and fosters regional cooperation on transboundary resource management. International funding mechanisms, such as the Green Climate Fund, should prioritize projects in conflict-affected and fragile states, with explicit security co-benefits. Conversely, counterterrorism budgets should allocate meaningful resources for climate adaptation, livelihood support, and governance strengthening—not just for arms and surveillance.

The connection between melting glaciers and bombings in the Sahel may seem distant, but they are part of the same system. Failing to address the environmental roots of insecurity will only ensure that new grievances emerge faster than old ones can be resolved. By embracing a broader, integrated vision of security—one that includes water, food, land, and climate resilience—governments can not only reduce the drivers of terrorism but also build more stable, prosperous, and peaceful societies for the long term.
