Climate stress is tightening its grip on vulnerable communities across the Middle East and North Africa, where water scarcity, conflict, weak public services and economic pressure are combining to narrow the choices available to millions of people.

The region’s exposure is no longer defined by heat and drought alone. Families in fragile rural districts, informal urban settlements, refugee camps and conflict-affected towns are being pushed into a convergence trap, where environmental decline collides with poor governance, limited investment and insecurity. The result is a growing struggle to adapt in place, move safely or remain with dignity.

Temperatures across the region are rising at roughly twice the global average, with 2024 recorded as the hottest year for the area. Heatwaves above 50C have become a severe public health and labour risk in parts of the Gulf, Iraq, North Africa and the Levant. Droughts have intensified in Morocco, Algeria and Tunisia, while flash floods have hit Gulf states and other countries where drainage, planning and emergency systems have not kept pace with urban growth.

Water sits at the centre of the crisis. The Middle East and North Africa includes many of the world’s most water-scarce countries, and the pressure is deepening as populations grow, aquifers decline and agriculture remains heavily dependent on inefficient irrigation. Climate shocks are also making rainfall less predictable, reducing crop yields, raising food prices and weakening livelihoods in areas already affected by debt, unemployment and reduced public spending.

The displacement picture is increasingly complex. Conflict remains the dominant driver in places such as Sudan, Syria, Yemen, Gaza and Libya, but climate-related shocks are aggravating the conditions that force people to leave. Drought can destroy income before fighting begins. Floods can displace families already living in temporary shelters. Heat can make low-paid outdoor work unsafe, while water shortages intensify competition between farmers, herders and urban users.

Across the wider displacement system, conflict and disasters now overlap more often than they appear separately. Global internal displacement remained at severe levels at the end of 2025, with conflict displacements rising sharply and disasters continuing to uproot communities. The Middle East and North Africa reflects this trend through repeated movement, interrupted returns and the expansion of informal settlements around cities that lack affordable housing, sanitation and reliable water.

Governance failures magnify the damage. Many communities most exposed to climate stress have the least influence over land-use planning, water allocation, local budgets and recovery programmes. Marginalised groups, including refugees, informal workers, women-headed households and minority communities, often face legal or administrative barriers to aid, employment and housing. Where documentation is missing or status is uncertain, climate stress can become a pathway into deeper exclusion.

The economic dimension is equally significant. Food imports, fuel costs, subsidy pressures and strained public finances limit the capacity of governments to cushion shocks. Countries facing heavy debt burdens have less room to invest in desalination, wastewater reuse, early warning systems, climate-resilient agriculture and safer housing. Development lenders are pushing water security as an economic priority, but financing gaps remain large and local delivery is uneven.

Urbanisation is reshaping the risk map. Cities such as Cairo, Casablanca, Amman, Beirut, Baghdad and Sana’a are absorbing people fleeing conflict, drought and collapsing rural livelihoods. Many arrive in peripheral districts where rent is lower but services are weaker. These neighbourhoods face higher exposure to heat, flooding and disease, while residents often lack secure tenure, making relocation or upgrading politically and legally difficult.

Rural areas face a different but connected squeeze. Farmers and pastoralists are dealing with declining water tables, degraded land and more volatile seasons. Some households send young men to cities or abroad while others sell livestock, reduce meals or pull children from school. These coping strategies can delay displacement, but they also weaken long-term resilience and reduce the ability to recover after the next shock.

The emerging policy challenge is to treat climate mobility as a development and governance issue, not only as a humanitarian emergency. Adaptation programmes that ignore conflict dynamics may fail, while security policies that ignore water and livelihoods can deepen grievances. Effective responses require credible local institutions, transparent water management, social protection, legal pathways for mobility and targeted support for communities hosting displaced people.

Early warning systems are expanding but remain uneven. Better forecasting can save lives during floods and heatwaves, yet warnings must be linked to shelters, transport, health services and trusted local communication. Without that chain, alerts do little for people who cannot afford to move, have nowhere safe to go or fear losing access to work, aid or legal protection.
