Challenges Facing Climate Refugees: Legal Gaps, Resettlement Issues, and Human Rights Concerns

When we talk about climate change, conversations often focus on rising temperatures, melting ice caps, and extreme weather events. But behind these statistics lies a growing human crisis: millions of people forced to leave their homes due to environmental changes they didn’t cause. These individuals, commonly referred to as climate refugees, face a unique set of challenges that remain largely unaddressed by the international community. From legal recognition gaps to resettlement difficulties and human rights vulnerabilities, the obstacles confronting climate-displaced populations demand urgent attention.

The legal protection gap: Why climate refugees remain invisible 🔗

One of the most pressing challenges facing people displaced by climate change is the absence of legal recognition under international law. The 1951 Refugee Convention, the foundational document for refugee protection worldwide, defines a refugee as someone fleeing persecution based on race, religion, nationality, membership in a particular social group, or political opinion. Climate change does not appear anywhere in this definition.

This creates a significant problem. The 1951 Convention and its 1967 Protocol remain the key legal documents that form the basis of international refugee protection. These instruments outline refugees’ rights and establish the standards for their treatment. However, people who flee rising seas, desertification, or climate-related disasters simply do not qualify under these established criteria.

UN Secretary-General António Guterres has described this gap as a “legal void” that leaves millions without protection. While the term “climate refugees” has gained traction in public discourse and media, it carries no legal meaning. The UNHCR does not officially endorse the concept, instead categorising climate-displaced individuals as “persons of interest” rather than persons under protection.

Regional frameworks offer limited hope 🔗

Some regional instruments have attempted to address these gaps. The 1969 Organisation of African Unity Convention and Latin America’s 1984 Cartagena Declaration define refugees more broadly, including those seeking refuge abroad due to events “seriously disturbing public order.” These definitions could potentially cover climate-related displacement. The African Union’s Kampala Convention also provides protections for internally displaced persons, including those displaced by environmental factors.

However, these regional frameworks remain limited in scope and lack universal application. Many climate-vulnerable nations in Asia and the Pacific, where sea-level rise poses existential threats, have no such protective instruments in place.

Internal displacement: The hidden crisis 🔗

A critical aspect of climate-induced migration is that the majority of people forced to flee due to climate-related disasters stay within their own countries. This internal displacement creates a significant protection gap because international refugee frameworks are designed for those who cross borders.

At the end of 2024, 9.8 million people were internally displaced due to ecological disasters. The World Bank predicts that climate change will cause 216 million people to be internally displaced by 2050, affecting six major regions: Sub-Saharan Africa, South Asia, East Asia and Pacific, North Africa, Latin America, and Eastern Europe and Central Asia.

Limited protections for internal displacement 🔗

The 1998 UN Guiding Principles on Internal Displacement provide a framework for protecting victims of natural disasters who do not cross international borders. However, these principles remain non-binding, meaning countries have no legal obligation to implement them. While they were used to draft the Kampala Convention for Africa, no equivalent binding framework exists at the global level.

Internally displaced people often find themselves in precarious situations. They cannot access benefits under international refugee frameworks, yet they may have lost everything-their homes, livelihoods, and communities. Many end up in overcrowded urban areas with inadequate housing and strained infrastructure, competing for limited resources with established residents.

Resettlement challenges: More than finding a new home 🔗

For climate-displaced populations, finding a safe place to resettle presents enormous difficulties. In some cases, native territories become completely uninhabitable, requiring permanent relocation. Small island nations such as Kiribati, Tuvalu, and the Maldives face the very real prospect of disappearing beneath rising seas.

Kiribati has taken the extraordinary step of purchasing land in Fiji as part of a “migration with dignity” strategy, attempting to ensure its population can relocate while preserving cultural identity. Yet such proactive measures remain rare, and most climate-vulnerable populations lack the resources or international support to plan for permanent relocation.

Integration barriers in host communities 🔗

Even temporary displacement presents significant challenges in host destinations. Climate migrants often encounter barriers to integration that echo those faced by conventional refugees. No international legal category for climate refugees exists, and climate change is not grounds for international protection. This means that climate migrants often lack access to the services and support systems available to recognised refugees.

Host communities may also resist accepting newcomers, particularly when resources are already scarce. Migrants often face discrimination from host communities and limited access to essential services such as education and healthcare. The absence of legal status makes it difficult for climate migrants to secure employment, access housing, or exercise basic rights.

Research suggests that successful integration requires addressing where migrants should be located, how to foster contact between migrants and existing residents, whether to prioritise work or training, and how to provide mental health services. Yet without legal recognition or dedicated support programmes, climate migrants are largely left to navigate these challenges on their own.

Human rights vulnerabilities: Life on the margins 🔗

Climate migrants frequently experience human rights abuses, unequal access to livelihood opportunities, and barriers to meeting basic needs. The vulnerabilities they face often mirror those of conventional refugees, yet without the legal protections that come with refugee status.

Gender-based discrimination and violence 🔗

Women and girls displaced due to climate change often have fewer livelihood opportunities and limited access to health care. They are exposed to higher risks of sexual and gender-based violence, forced labour, exploitation, abuse, and human trafficking. In some societies, women and girls unaccompanied by a male family member may face discrimination and barriers to accessing basic services. Child or forced marriage becomes more common, and girls may drop out of school.

Impacts on children and vulnerable groups 🔗

Climate-induced displacement disproportionately affects children, adolescents, and older adults. Over 30.5 million displaced children and adolescents face persistent challenges in accessing basic services, hindering their rights to education, health, protection, and non-discrimination. When forced to migrate, children are removed from stable homes and supportive communities, leaving them vulnerable to family separation, child labour, child marriage, violence, exploitation, and trafficking.

Older adults and people with disabilities may face difficulties fleeing from areas affected by sudden-onset climate events. When families flee disaster zones, they may leave behind vulnerable members who cannot travel, further fragmenting communities and support networks.

Cultural and social challenges 🔗

Beyond physical safety concerns, climate migrants face difficulties with language, food, and cultural adaptation. Entire communities must grapple with the loss of ancestral lands and traditional ways of life. For indigenous peoples, whose identities are often deeply connected to specific places, displacement can mean the erosion of cultural heritage that has developed over generations.

Religious persecution and ethnic discrimination may compound these challenges, particularly when climate migrants move to areas with different demographic compositions. The lack of social networks and community support in new locations can lead to isolation and mental health struggles.

Emerging legal developments: Signs of progress 🔗

Despite the gaps in international law, some positive developments have emerged. In 2019, the UN Human Rights Committee delivered a landmark decision affirming that countries have an obligation not to deport or remove an individual to a country where their right to life is at risk due to climate change. This principle of non-refoulement offers some protection for climate-displaced people.

National courts in several countries have extended protections to climate-induced migrants. In Colombia, the Constitutional Court ruled that a lack of specific protection provisions should not be a barrier to protecting climate-induced internally displaced people. In Italy, the Supreme Court ordered that refugee adjudicators cannot ignore claims of instability due to environmental degradation and climate change.

In July 2025, the Inter-American Court of Human Rights issued an advisory opinion stating that countries must maintain regulatory and policy instruments to address forced displacement caused by climate change, prioritising the right to adequate housing and resettlement.

The path forward: What needs to change 🔗

Addressing the challenges facing climate refugees requires action on multiple fronts. First, the international community must develop a comprehensive legal framework that recognises climate displacement as a legitimate basis for protection. Some experts advocate for amending the 1951 Refugee Convention, while others propose creating entirely new instruments specific to climate migration.

Second, countries should strengthen the principle of non-refoulement to ensure that no one is returned to a place where climate change threatens their right to life. Third, investments in adaptation and resilience can help vulnerable communities remain in place where possible, reducing the need for forced displacement.

Finally, receiving communities need support to facilitate the integration of climate migrants. This includes funding for housing, healthcare, education, and employment services, as well as programmes to foster understanding between newcomers and established residents.

What do you think? As climate change intensifies and displacement numbers continue to rise, should the international community create a new legal framework specifically for climate refugees, or should existing instruments be expanded to cover those fleeing environmental disasters?
