Displacement

The climate emergency is the defining crisis of our time, impacting every region across the globe. Climate change is driving displacement and increasing the vulnerability of those already forced to flee.
Here’s how UNHCR is taking action:
Law & Policy
to develop enhanced protection for people displaced in the context of disasters and climate change
Operations
enabling refugee communities to tackle climate change and reduce their environmental impact
COP28
ensuring refugee voices are heard
Why is climate change a concern for UNHCR?
Refugees, internally displaced people and stateless persons are on the frontlines of the climate emergency. Many are living in ‘climate change hotspots’, like Pakistan and the Horn of Africa, where the risk of extreme weather events is increasing but they typically lack the resources to adapt to an increasingly inhospitable environment.
While climate change does not directly cause conflict, it is a ‘risk multiplier’ for other drivers of displacement. Climate change triggers a domino effect of disaster upon disaster, exacerbating existing tensions and adding to the potential for conflicts.
For example, in Cameroon in the Sahel region of West Africa, temperatures are rising 1.5 times faster than the global average, diminishing water supplies, killing crops and creating food insecurity. Fishermen tried to retain the remaining water by digging trenches, but these trapped the local farmer’s cattle leading to an eruption of violence among the two groups. Many people died during the conflict and many more were forced to flee, leaving their homes behind.
How is climate change impacting the lives of refugees and displaced people?
Around 84% of the world’s refugees live in ‘climate change hotspots’, areas which are more likely to be affected by the adverse impacts of climate change. The effects of climate change, like extreme weather events, are hugely detrimental and increase the vulnerability of refugees and displaced people.
For example, recurring storms and floods in conflict areas add to the burden on affected people and governments, leaving them no room to recover. In turn, conflict may increase vulnerability to disasters – limiting the availability of safe places to shelter and basic infrastructure to respond. Fear of targeted attacks can also leave displaced people exposed to the elements.
What does the future of climate change look like?
Over the past 50 years, there has been a five-fold increase in weather-related disasters. Climate change and increasingly extreme weather events have caused a surge in natural disasters, disproportionately impacting poorer countries. More than 91% of deaths related to natural disasters occurred in developing countries.
Although the number of deaths have fallen sharply between 1970 and 2019 due to improved early warning systems and disaster management, the number of deaths remains high. Droughts were the biggest killers, responsible for 650,000 deaths, followed by storms and floods. Mami Mizutori, UN Special Representative and head of the Office for Disaster Risk Reduction said that, “More international cooperation is needed to tackle the chronic problem of large numbers of people being displaced each year by floods, storms and drought.”
How is UNHCR addressing climate change and disaster-related displacement?
UNHCR’s climate action is focused on three main areas:
1. Law and policy: Providing legal advice, guidance and support to the international community to develop enhanced protection for refugees and other people displaced in the context of disasters and climate change, and catalysing international discussions on their rights
2. Operations: Reducing environmental degradation in displacement settings and enhancing the preparedness and resilience of displaced people and host communities to the effects of climate change. A key aspect of disaster preparedness and response is to anticipate, addressing the root causes of displacement to reduce the reasons why people are displaced in the first place.
3. UNHCR’s environmental footprint: Improving UNHCR’s environmental sustainability by reducing our greenhouse gas emissions and minimizing negative impacts on the environment.
What is UNHCR doing to reduce its impact on the environment?
UNHCR is taking steps to reduce its impact on the environment. For example, implementing clean energy solutions in field offices and reducing transport-related emissions. The Green Box Initiative supports the installation of energy meters in UNHCR offices that connect to a global dashboard for monitoring the organization’s power consumption and suggesting alternative energy solutions.
What about the term ‘climate refugee’?
Under international law a refugee is defined as ‘someone who is unable or unwilling to return to their country of origin owing to a well-founded fear of being persecuted for reasons of race, religion, nationality, membership of a particular social group, or political opinion.’ Climate change impacts people inside their own countries, and usually creates internal displacement before it escalates leading people to cross borders.
Therefore, UNHCR refers to ‘persons displaced in the context of disasters and climate change’ as this is more accurate.
How can I help?
Addressing climate change is a collective responsibility. We must tackle climate change together, and hold each other accountable.

UNHCR scales up response to catastrophic floods in Pakistan
UNHCR, the UN Refugee Agency, is mobilising resources and staff to scale up its assistance in Pakistan to support local communities and refugees in areas devastated by the catastrophic floods.
Refugees and locals in Mauritania exchange strategies for adapting to climate change.
When Ahmedou Ag ElBokhary arrived at Mbera refugee camp in south-eastern Mauritania after fleeing Mali’s conflict in 2012, he was surprised by the lack of vegetable gardens in nearby villages.
In Honduras, climate change is one more factor sparking displacement
With hurricanes and other extreme weather events becoming ever more powerful and frequent, increasing numbers of people in gang-wracked Honduras are having to flee their homes.
