Climate migrants are a burgeoning population at the forefront of one of the most pressing global challenges of the 21st century: climate change. As the Earth’s climate continues to rapidly evolve, driven primarily by human-induced factors such as greenhouse gas emissions, rising sea levels, extreme weather events, and environmental degradation, millions of people find themselves displaced from their homes each year. These individuals, known as climate migrants, are forced to flee their native lands due to increasingly inhospitable conditions that threaten their livelihoods, safety, and way of life. The phenomenon of climate migration represents a complex intersection of environmental, social, economic, and political factors, with far-reaching implications for both the migrants themselves and the communities they seek refuge in. As the frequency and intensity of climate-related disasters escalate, the issue of climate migration demands urgent attention and comprehensive solutions at local, national, and international levels.
- According to the International Organization of Migration (IOM), climate-induced migration is defined as the relocation of an individual or groups of individuals who, mainly due to abrupt or gradual changes in the environment caused by climate change, are compelled to depart from their usual place of residence.
- This relocation may be either temporary or permanent, occurring within a state or across international borders.
- Climate migration falls within the broader category of environmental migration, specifically denoting a unique form where the environmental changes are a result of climate change.
HOW CLIMATE CHANGE CAUSES MIGRATION
Climate change triggers migration through various mechanisms:
- Intensification of Natural Disasters:
- The escalation in the frequency and severity of natural disasters, such as hurricanes, floods, and wildfires, can render areas uninhabitable, compelling people to migrate to safer regions.
- Impact on Agriculture and Water Access:
- Increased temperatures and prolonged droughts can adversely affect agricultural productivity and water resources, leading to food shortages and scarcity. In response, communities may migrate in search of more sustainable living conditions.
- Rising Sea Levels:
- The rise in global temperatures contributes to the melting of polar ice caps and glaciers, resulting in rising sea levels. This phenomenon poses a significant threat to coastal areas, making them unsuitable for habitation. Communities residing in these vulnerable zones may be forced to relocate.
- Coastal Area Vulnerability:
- A substantial portion of the global population resides in coastal areas. As sea levels rise, these regions become more susceptible to flooding and storm surges, prompting inhabitants to move to safer inland locations.
- Resource-Induced Conflict:
- Climate change can exacerbate competition over essential resources such as water, arable land, and fisheries. This heightened competition may lead to conflicts, subsequently driving migration as individuals seek refuge from the impacts of resource-related disputes.
SCALE OF CLIMATE-INDUCED MIGRATION
The scale of climate-induced migration has reached significant proportions, as indicated by various global assessments:
- Worldwide Impact:
- The World Economic Forum reports that from 2008 to 2016, more than 20 million people annually were compelled to become climate refugees due to extreme weather events. This highlights the widespread and persistent nature of climate-induced displacement on a global scale.
- Projected Environmental Refugees:
- The World Bank’s projections are particularly alarming, estimating that by the year 2050, approximately 1.2 billion people could be categorized as environmental refugees. This staggering figure underscores the potential magnitude of the issue and the urgent need for proactive measures to address and mitigate climate-induced migration.
- Regional Focus – South Asia:
- South Asia, in particular, is anticipated to witness a substantial impact, with expectations of over 40 million climate migrants. This region faces diverse climate challenges, including rising sea levels, extreme weather events, and disruptions to agriculture, contributing significantly to the scale of climate-induced migration.
- Annual Displacements:
- According to the United Nations, disasters and geophysical hazards have resulted in an average of 3.1 million displacements each year since 2008. This statistic reflects the recurrent nature of climate-related events leading to population displacement and highlights the need for ongoing attention to this global challenge.
IN CONTEXT OF INDIA
India faces a significant and growing challenge of climate-induced migration, marked by various alarming indicators:
- Global Vulnerability Ranking:
- India is particularly vulnerable to climate-induced migration, as evidenced by its 7th position in the Global Climate Risks Index for the year 2021. This ranking underscores the heightened risks and impacts of climate-related events affecting the country.
- Himalayan Region Impact:
- The hills, especially in the Himalayan region, are witnessing an elevated scale of migration. Entire ghost villages and abandoned habitations scattered across the Himalayas highlight the substantial impact of climate change on traditional livelihoods. Census data from 2011 reveals that a significant number of villages, totaling 1,053, have no inhabitants, and 405 villages have fewer than 10 residents.
- Cyclone-Induced Migration:
- Specific climate events, such as Cyclone Phailin in 2013, have triggered unprecedented migration patterns. Coastal areas, like the state of Odisha, experienced large-scale migration of fishing communities that had been settled there for decades. The cyclone’s impact disrupted established communities and forced residents to migrate.
- Environmental Disasters and Displacements:
- In 2018, India witnessed over 2.7 million displacements as a result of environmental disasters. This includes events such as floods, cyclones, and other climate-related incidents that have a direct impact on communities, often leading to migration as a coping mechanism.
- Future Migration Projections:
- The future scenario is grim, with projections suggesting that, in a business-as-usual scenario, approximately 45 million people in India alone will be compelled to migrate from their homes due to climate disasters by the year 2050. This alarming figure underscores the urgent need for proactive measures to address the impacts of climate change on vulnerable populations.
CHALLENGES
Global Issues
- Lack of Clear Definition:
- The absence of a universally accepted and clear definition poses a challenge in understanding and addressing human migration linked to climate change. Migration is often influenced by a complex interplay of multiple factors, where climate change may be just one contributing element.
- Resource Constraints:
- The UNHCR’s classification of affected individuals as “environmental migrants” rather than granting refugee status is driven, in part, by resource limitations. The insufficiency of resources hinders the ability to adequately address the unique needs and challenges faced by climate-induced migrants.
- Data Deficiency:
- A persistent challenge lies in the scarcity of reliable data, hindering efforts to establish a comprehensive understanding of the relationship between migration and the environment. Collecting accurate data on migration and its environmental dimensions remains a challenging task in itself.
Challenges Specific to India:
- Poverty and Size:
- India’s vast size and high levels of poverty create a conducive environment for climate-induced migration. The majority of the country’s impoverished population resides in rural areas, which are more susceptible to climate-driven shocks due to their limited adaptive capacity.
- Rural-Urban Migration Dynamics:
- Rising rural distress, coupled with an economic growth focus on urban areas, is leading to increased migration from rural to urban settings. Climate change exacerbates this trend by pushing more individuals to seek livelihoods in cities.
- Urban Vulnerability:
- The unplanned expansion of Indian cities contributes to their heightened vulnerability to the impacts of climate change. Urban areas, ill-prepared for climate-related challenges, face increased risks. Rural-urban migration is expected to intensify as agriculture-dependent livelihoods encounter escalating climatic stress.
