Climate Change Is Reshaping Migration in Southern Africa

In early 2023, floods in Mozambique’s Zambezia Province displaced thousands of families. Many crossed borders into neighbouring countries such as South Africa in search of safety and livelihoods. Among them were children who had lost homes, schooling, and access to healthcare. Similar climate shocks—cyclones, droughts, and floods—are becoming more frequent across the Southern African Development Community (SADC).

Climate change now acts as a powerful driver of human mobility. According to the Internal Displacement Monitoring Centre, weather-related disasters displaced more than 32 million people globally in 2022 alone. Southern Africa contributes a growing share of these movements. Droughts in Zimbabwe, floods in Mozambique, and cyclones along the Indian Ocean coast push families to move internally or across borders.

Children face the greatest risks in these movements. Migration disrupts schooling, exposes children to trafficking, and limits access to healthcare and protection services. Policymakers across the SADC region must therefore address a new reality: climate-induced migration is no longer only an environmental issue. It is also a child protection and public health challenge.

This article examines how climate-driven migration affects children in the SADC region. It also analyzes policy gaps, presents real-world examples from South Africa’s major cities, and proposes practical solutions for governments, NGOs, and health systems.

Climate Change and Migration Trends in the SADC Region

Climate shocks increasingly shape migration patterns across Southern Africa. Cyclones, floods, prolonged droughts, and food insecurity drive many families to move.

The devastating Cyclone Idai in 2019 marked a turning point for regional migration patterns. The storm affected Mozambique, Zimbabwe, and Malawi. More than three million people were impacted, and many households lost homes and livelihoods. Several communities relocated permanently.

More recent events reinforce this trend. The Cyclone Freddy in 2023 caused massive displacement across Malawi and Mozambique. Many families migrated internally, while others moved toward South Africa and Botswana.

Climate-related migration often follows predictable routes. Migrants frequently travel to major economic hubs where jobs and services are available. In South Africa, cities such as Johannesburg, Pretoria, Cape Town, and Durban host growing migrant populations.

However, climate migrants rarely receive formal protection. International law does not currently recognize “climate refugees.” As a result, many families enter host countries through irregular channels. This status increases vulnerability—especially for children.

Why Children Are Particularly Vulnerable

Children experience climate migration differently from adults. Displacement disrupts several key systems that protect child wellbeing.

First, migration often interrupts education. Children who cross borders may lack documentation required for school enrolment. Even when schools accept them, language barriers and financial constraints limit attendance.

Second, displaced children face health risks. Overcrowded housing and poor sanitation increase exposure to infectious diseases. Migrant children also struggle to access immunization programs and primary healthcare.

Third, migration exposes children to exploitation. Unaccompanied minors are particularly vulnerable to trafficking and labour exploitation along migration routes.

Data from UNICEF show that climate shocks already affect approximately one billion children worldwide. Many live in regions highly vulnerable to climate change, including Southern Africa.

Gender and age further shape vulnerability. Adolescent girls face heightened risks of early marriage, sexual violence, and school dropout during displacement. Younger children face malnutrition and interrupted vaccination schedules.

Evidence From South African Cities

South Africa remains the main destination for migrants in the SADC region. Climate-related migration adds to existing labour and political migration patterns.

Johannesburg

Informal settlements around Johannesburg host large migrant communities from Zimbabwe, Mozambique, and Malawi. Many families displaced by drought or floods settle in overcrowded housing.

Public health practitioners report several recurring challenges:

interrupted childhood immunization schedules
increased respiratory infections linked to overcrowding
limited access to documentation required for social services

Clinics often serve migrant children without formal identification. However, administrative barriers still discourage families from seeking care.

Durban

The coastal city of Durban receives migrants from Mozambique following cyclones and flooding events. Many families settle in peri-urban settlements.

Local NGOs report rising numbers of migrant children who lack birth certificates or school records. Without documentation, these children struggle to access education and social protection programs.

Cape Town

In Cape Town, drought-driven migration from rural Southern Africa has increased pressure on housing and social services. Migrant children often live in informal settlements where access to sanitation and safe water remains limited.

These conditions create additional public health risks, including diarrhoeal diseases and malnutrition.

Policy Frameworks: Progress and Gaps

Several regional and national policies address migration and child protection. However, climate-induced mobility remains poorly integrated into these frameworks.

Regional Policy

The Southern African Development Community promotes regional cooperation on migration and disaster response. Yet its migration frameworks still focus primarily on labour mobility.

Similarly, the African Union has developed the Migration Policy Framework for Africa. While the policy recognizes environmental migration, implementation remains limited.

South African Policy Context

South Africa’s Children’s Act 38 of 2005 provides strong legal protections for all children, regardless of nationality. The law guarantees access to basic services, including healthcare.

The Refugees Act 130 of 1998 also protects individuals fleeing persecution. However, climate migrants rarely qualify under the current definition of refugees.

Health policy frameworks such as the National Health Act 61 of 2003 allow access to primary healthcare services for children. Yet administrative barriers still limit implementation.

As a result, migrant children often fall into policy gaps. They are neither recognized as refugees nor fully integrated into social protection systems.

Case Examples From Migrant Communities

Case Example 1: Cyclone Displacement and School Access

A Mozambican family displaced by flooding relocated to Johannesburg in 2022. Their two children attempted to enroll in a public school but lacked birth certificates.

Local NGOs intervened and helped the family obtain temporary documentation. The children eventually gained school access. However, the process took several months, delaying their education.

Case Example 2: Health Access in Durban

In Durban, a Malawian family displaced by drought sought healthcare for their toddler suffering from respiratory illness.

Although clinics provided treatment, the parents initially hesitated to visit health facilities due to fears of immigration enforcement. This hesitation delayed care and worsened the child’s condition.

Case Example 3: Unaccompanied Minor in Cape Town

A teenage boy arrived in Cape Town after travelling alone from Zimbabwe following prolonged drought. Without guardianship or documentation, he struggled to access social services.

A migrant support organization eventually connected him with legal assistance and shelter. However, similar children often remain invisible to authorities.

Innovative Programs and Emerging Solutions

Despite policy challenges, several initiatives across the region show promising results.

Community-Based Child Protection Networks

NGOs in South Africa have developed community child protection committees in migrant-dense neighbourhoods. These networks identify vulnerable children, support school enrolment, and refer families to health services.

Programs implemented by organizations such as Save the Children demonstrate how community-based monitoring can improve early identification of at-risk children.

Mobile Health Services

Mobile clinics have expanded healthcare access in migrant settlements around Johannesburg and Durban. These clinics provide vaccinations, maternal care, and nutrition screening.

Such programs reduce barriers created by documentation requirements and transport costs.

Cross-Border Early Warning Systems

Regional collaboration on disaster early warning systems also shows promise. Improved forecasting allows governments to prepare humanitarian responses before large-scale displacement occurs.

The World Meteorological Organization supports several early-warning initiatives across Southern Africa.

Policy Recommendations

Addressing climate-induced migration requires coordinated policy action across multiple sectors.

1. Recognize Climate-Driven Mobility in Migration Policy (1–2 years)

Governments should formally acknowledge climate-related displacement in national migration frameworks. Policymakers within the Southern African Development Community should develop a regional protocol addressing environmental migration.

Such recognition would help governments design protection mechanisms for affected populations.

2. Expand Child-Friendly Documentation Systems (1–3 years)

Governments should simplify birth registration and documentation for migrant children. Digital registration systems and cross-border data sharing could accelerate the process.

This step would improve access to education, healthcare, and social protection.

3. Strengthen Health System Inclusion (Immediate – 2 years)

Health departments should train frontline healthcare workers on migrant rights and child protection protocols.

Clear guidelines can reduce confusion around documentation requirements and ensure that children receive timely care.

4. Invest in Climate-Resilient Communities (3–5 years)

Long-term investments in climate-resilient infrastructure can reduce forced migration. Governments should prioritize drought-resistant agriculture, flood-resilient housing, and early-warning systems.

These interventions reduce displacement risks and protect vulnerable populations.

5. Support Community-Led Programs (Immediate – 3 years)

NGOs and local governments should expand funding for community-based child protection initiatives. These programs identify vulnerable children earlier and connect them with services.

Research Gaps and Limitations

Despite growing attention to climate migration, important evidence gaps remain.

First, reliable data on climate-induced cross-border migration in Southern Africa remain limited. Many migrants move informally, making accurate measurement difficult.

Second, research on migrant children often focuses on conflict or economic migration. Climate-driven displacement receives far less attention.

Finally, intersectional factors—such as gender, disability, and documentation status—require deeper analysis in migration health research.

Future studies should therefore integrate climate science, migration data, and public health outcomes.

Conclusion: A Call to Action

Climate change is reshaping migration patterns across Southern Africa. Families displaced by floods, droughts, and cyclones increasingly move across borders in search of safety and livelihoods.

Children face the most severe consequences. Migration disrupts education, healthcare access, and social protection systems. Without targeted policies, these vulnerabilities will intensify as climate impacts grow.

Governments, NGOs, and public health institutions must respond proactively. Policymakers should integrate climate mobility into migration frameworks. Health systems must ensure inclusive services for migrant children. Community organizations should continue building local protection networks.

Above all, regional cooperation will determine success. Climate-induced migration does not respect national borders. Effective solutions must therefore emerge through collaboration across the SADC region.

Protecting migrant children in the era of climate change is not only a humanitarian responsibility. It is also a public health imperative.
