# The Climate–Migration–Health Nexus: A Multisectoral Framework for Action, with Case Insights from MENA

## TL;DR

This paper introduces a framework to address how climate change, migration, and health are interconnected, using insights from the Middle East and North Africa.

## Contribution

The novel contribution is the Nexus Action Framework for Climate Change, Migration, and Health (NAF-CMH), promoting multisectoral collaboration.

## Key findings

- Climate change increases displacement and health risks in the MENA region.
- The proposed framework integrates health into climate adaptation and migration governance.
- Seven pillars for coordinated action are identified based on literature and expert insights.

## Abstract

The convergence of climate change, migration, and health represents a critical global challenge, with the Middle East and North Africa (MENA) region illustrating acute vulnerabilities while offering insight relevant beyond the region. Increasing exposure to extreme heat, droughts, and floods drives displacement, constrained mobility, and adaptive migration, placing additional pressure on already stretched health systems. This paper proposes an integrated Nexus Action Framework for Climate Change, Migration, and Health (NAF-CMH) to address these interlinked dynamics and move beyond fragmented, sector-specific responses. The framework conceptualizes human mobility both as a potential resilience strategy and as a determinant of health, encompassing climate-affected migrants, displaced populations, and those experiencing involuntary immobility across diverse pathways and settings. It promotes systematic integration of health considerations into climate adaptation and migration governance and situates these interventions within the broader agenda of climate-resilient health systems. Drawing on a non-systematic narrative review of peer-reviewed and grey literature, complemented by the authors’ expertise, the paper identifies seven interrelated pillars for coordinated policy and operational action. While grounded in MENA-specific vulnerabilities, the framework is flexible and adaptable to other regions facing climate-driven mobility challenges. By providing an operational architecture for multisector collaboration, the NAF-CMH supports policymakers, public health authorities, and migration actors in strengthening resilience, reducing vulnerability and safeguarding health amid accelerating climate impacts and evolving mobility patterns.
