INTRODUCTION
The changing climate induces migration and displacement of people because of environmental degradation and disasters, which has led to the concept of climate refugees, which has an entirely different meaning from that of a refugee.
Climate change is a pressing issue that requires immediate attention, as it forces people to leave their homes and face numerous challenges, including a lack of necessities like food, shelter, education, and employment.
These situations put their basic human rights at extremely high risk. In addition to this, climate refugees are not recognized by international law since they are not categorized in the Refugee Conventions of 1951.
Therefore, it implies that millions of displaced people remain vulnerable and without any form of protection and support, either from the host country or the international community.
CAUSES OF CLIMATE-CAUSED DISPLACEMENTS

Rise in Sea Level
Rising temperature: As temperatures increase globally, glaciers and ice caps in regions like the Arctic and Antarctic begin to melt, leading to a rise in sea levels. Coastal communities will be periodically inundated because of this, and individuals in low-lying areas, such as the Pacific Islands, Bangladesh, and certain African countries, will be displaced as they seek to cross borders and find new homes in safer areas.
Major Weather Events
Events of major weather may cause mass migrations because of natural disasters such as hurricanes, cyclones, floods, earthquakes, and other extreme conditions. Southern East Africa will be disproportionately affected by disasters, with certain sub-Saharan zones expected to be at the end of the spectrum. It will be rather difficult to return to their places of origin because of the level of devastation.
Water scarcity
Water scarcity is an issue that will be exacerbated by climate change, particularly in locations that are already vulnerable. Climate change and warming will exacerbate the availability of freshwater in arid regions such as the Middle East and North Africa.
Draughts and Desertification
Droughts and desertification will be caused by major weather events, including but not limited to rising temperatures. Sub-Saharan Africa, the Sahel, and parts of Asia will be highly impacted.
Agricultural areas will become too hostile and unproductive to sustain local farming communities. Farmers will be at the receiving end of more droughts and will be unable to produce food to feed themselves and their families, thus leading to community migration in a search for water, food, and arable land.

Places where large-scale migrations are taking place

The Pacific Islands
Sea levels have risen, and storms have grown more violent, resulting in floods and saltwater encroaching on drinking water reserves. In the Pacific Islands, entire islands have become uninhabitable and cannot support their populations, as seen in Kiribati, Tuvalu, and the Marshall Islands.
Sub-Saharan Africa
Droughts, desertification, and food insecurity have been the cause of significant migrations in sub-Saharan Africa, where the agricultural land has become unproductive due to unpredictable weather and altered precipitation. Due to a lack of water and food, the rural populace has been forced to move in search of water and arable land. The impacted areas include the Sahel, Sudan, and parts of Ethiopia, Somalia, and Kenya.
Bangladesh
The places most impacted by this change in Bangladesh are the coastal areas, particularly around the Bay of Bengal. People from low-lying areas are being relocated due to flooding, cyclones, and rising sea levels. Bangladesh is also a victim of a different form of migration, caused by the erosion of riverbanks and storm surges, which force people to move from rural areas to cities or to another neighboring nation.
LEGAL GAPS AND POLICY CHALLENGES

Absence of legal protection
Presently, there is an absence of any international legal mechanism in place for climate refugees. According to the Refugee Convention of 1951, a refugee is defined as an individual who is compelled to leave their home because of persecution and discrimination on the grounds of race, religion, nationality, or membership of a particular social group.
The law is mute on the issue of climate migrants; thus, it is an indicator of the fact that they lack the legal rights to the requisite protection and recognition. This situation also means they are ineligible for refugee rights and assistance in this regard.
Barriers to cross-border mobility
Crossing borders is a key challenge for most climate migrants, as they are frequently denied entry to other countries due to concerns about security, resources, or the complexity of the immigration process.
Some nations provide short-term relief on humanitarian grounds, but a few countries do not have a long-term plan to address this scenario. A climate refugee who cannot return to their country of origin nor have an option to resettle into any other host country is at the mercy of a few available options, thus creating a difficult life.
Limited funding
Insufficient resources are a significant issue at the international level for climate migrants. Due to inadequate financial resources, agencies like the United Nations are unable to respond adequately and swiftly to the various challenges faced by climate migrants.
Most of the funding available to the United Nations for this crisis is in the form of emergency humanitarian aid in response to natural disasters, with fewer resources allocated to longer-term issues such as relocation, job creation, and infrastructure development.
Political resistance
Climate migration is a hot-button topic in many countries. Individuals may struggle to live life to their fullest potential by taking control of their lives and creating their own vision for a better future. National sovereignty, fear of resource scarcity, and population stress are factors that prompt hesitation to accept climate migrants.
For example, some nations view climate refugees as a burden and a potential hazard to their resources and are not willing to accept the movement of the same within their borders.
Absence of regional arrangements
Regional accords, such as the Pacific Islands Forum, have acknowledged that rising sea levels are an issue for countries. However, the regional pacts have been lacking in terms of financial and infrastructural resources and are frequently inadequate to deal with major population movements. However, a vast international consensus is still not in place to address and manage the movement, resettlement, and relocation of these climate migrants.

FAQs About Climate Refugees
What are climate refugees, and how do they differ from traditional refugees?
Climate refugees are people forced to leave their homes due to environmental changes such as rising sea levels, droughts, or extreme weather events. Unlike traditional refugees who flee persecution or conflict, climate refugees are displaced by climate-induced disasters. However, they are not legally recognized under the 1951 Refugee Convention, leaving them without formal protection or asylum rights.
Which regions are most affected by climate-induced displacement?
Regions most vulnerable to climate displacement include the Pacific Islands, Sub-Saharan Africa, and Bangladesh. These areas face severe challenges such as rising sea levels, desertification, and food and water scarcity. For instance, low-lying nations like Kiribati and Tuvalu are already witnessing permanent migration due to saltwater intrusion and loss of arable land.
Why are climate refugees not recognized under international law?
The 1951 Refugee Convention defines refugees as individuals fleeing persecution based on race, religion, or political opinion. Since environmental causes aren’t included in this definition, climate refugees lack formal legal status. This legal gap prevents them from accessing international protection, resettlement programs, and aid available to traditional refugees.
What are the main challenges faced by climate refugees?
Climate refugees often face limited mobility, lack of legal protection, and scarce financial aid. Many host countries hesitate to accept them due to political or resource concerns. In addition, the absence of regional agreements and insufficient international funding leave millions without shelter, food, education, and healthcare after displacement.
What steps can be taken to protect climate refugees?
To safeguard climate refugees, global leaders must update international refugee law to include climate-induced displacement, strengthen climate finance, and support adaptation measures in vulnerable regions. Creating safe relocation programs, investing in resilient infrastructure, and promoting sustainable livelihoods can also reduce forced migration and ensure long-term stability for affected populations.
CONCLUSION
Numerous environmental changes, including droughts, extreme weather, and rising sea levels, are significantly impacting the world population. The world population is continuously increasing, but many of those being displaced are not recognized as climate refugees.
Climate change effects such as sea level rise, desertification, and environmental disasters have displaced millions of people in the regions of Bangladesh, sub-Saharan Africa, and the Pacific islands. They lose their homes, lives, and access to such basic needs as food and health care.
Future Perspective
- The most long-term solutions involve extending international law to recognize climate change-induced displacement through a modified or entirely new framework.
- Amend the 1951 Refugee Convention or draft a new protocol to grant climate refugees the right to legal asylum.
- Invest in farming and infrastructure that will help adapt communities already at risk from climate change.
- Provide safe, government-backed relocation programs for residents of uninhabitable regions.
- Increase global assistance and climate financing from developed countries to the affected regions.
- Promote green jobs and education in at-risk communities in the developing
- Enhance the monitoring of climate migration to make better policies and prepare for potential dangers.
