Floods, heatwaves, and other extreme weather events have displaced hundreds of thousands of people in Iran, with repercussions for residents including the 3.4 million refugees and other forced migrants, who are restricted to climate-affected areas. Environmental challenges may also be pushing some people to move internationally. This article offers a rare look at the climate and migration dynamics in Iran.
Is climate change a major driver of migration and displacement? From where are people leaving, and where are they going? This informative primer, a Climate Migration 101 of sorts, provides answers to basic questions about climate change and migration, starting with how and where climate change triggers human movement.
Despite the widespread impression that people inevitably migrate away from climate-vulnerable areas, many adapt to environmental changes, choose to remain in their homeland, or simply cannot leave, due to a lack of money, connections, legal avenues, or other means to do so. These “trapped populations” may be among the most affected victims of climate change, this article explains.
Researchers often seek to predict how many people will move due to climate change, but beyond the inherent forecasting difficulties, their work is complicated by the fact that terms such as "climate migrant" are nebulous and migration drivers are often multifaceted. Instead, this article explains why analysts might ask how climate change will reshape existing patterns of migration and immobility.
Can haphazard, unplanned climate displacement be turned into voluntary, safe migration? Projects explicitly aimed at addressing internal and international climate migration are rare, but development organizations increasingly are turning their attention to supporting them. This article catalogues climate mobility projects around the world and examines their primary goals, whether to support the movement or stay of people or help at destination.
Catastrophic drought has thrust tens of millions of people in East Africa into acute food insecurity, raising the specter of famine. The extreme weather crisis, which follows years of conflict and economic disaster, has compounded long-running humanitarian challenges affecting refugees and internally displaced people, as this article explains.
The discovery of massive oil reserves off the Guyana coast will bring immense riches to this small South American country. This windfall will draw migrant labor and the return of some diaspora members to Guyana, which has one of the world's highest emigration rates. It also could accelerate climate displacement in a country where 90 percent of the population lives in coastal areas below the sea level. This article explores the changes ahead.
Climate change is compounding the drivers of displacement and international migration in Afghanistan, which has one of world's largest populations of internally displaced persons (IDPs). This article examines the climate and environmental linkages to displacement and migration, as well as the policy approaches taken by the Taliban and predecessor governments, particularly as they relate to water resources management.
A disproportionate number of Central American migrants traveling through Mexico to the United States come from Honduras, driven by government corruption, impacts of the coronavirus pandemic, and hurricanes that have devastated communities and livelihoods. This article examine the multiple factors behind migration from the country, drawing from interviews with migrants en route.
Climate change has had a devastating impact on many poor Central American farmers, which can contribute to food insecurity and may be prompting migration from the region's Dry Corridor. But the process is not straightforward. As this article explains, most poor farmers rely on a combination of buying, cultivating, and foraging for their food, which makes it difficult to predict how people will react to individual climate events.
Migration can help build resilience against the encroaching effects of climate change. Instead of being passive victims of environmental degradation, individuals sometimes move to gain money, knowledge, and skills that can fortify their household of origin. Migrant workers from Thailand demonstrate how and under what conditions this process works.
Climate-induced migration can lead to tensions and violence between host communities and new arrivals. This conflict can flare up at various levels, including among rural farmers and herders in relatively peaceful countries such as Tanzania.
Climate change is affecting human movement now, causing internal displacement and international migration, and will do so in the future. But the impact is often indirect, and rarely is the process as straightforward as one might think. This article provides an overview of research on how climatic hazards drive and affect migration, reviewing which types of people might migrate and under what conditions.
Coastal communities in India are confronting the effects of sea-level rise, erosion, flooding, and cyclones. This article examines displacement and migration from Odisha, the Sundarbans delta, and Majuli island in the state of Assam, examining national and state responses and the principles that could inform the design of policies to address displacement due to climate-related hazards.
While migration once was a lower-priority topic for African governments, the last decade has seen a deepening in governance. Policymakers have integrated migration into their national development strategies and mainstreamed it across policy domains such as health and education. The actions are promising on paper, yet questions remain about the extent to which they will translate to more effective migration management.
Indonesia, which has a long history as a major origin for migrant labor in the Asia-Pacific and beyond, more recently has reluctantly found itself a transit and destination country, including for asylum seekers. Still, policymakers remain focused on protection of its nationals abroad rather than on assuring the status of Chinese and other foreigners in the country. This country profile explores Indonesia's rich migration history.
Migrants displaced by crisis do not benefit from international protection the way that refugees do. This article examines the experiences of labor migrants amid manmade and natural disasters in the Central African Republic, Côte d’Ivoire, Lebanon, Libya, South Africa, and Thailand, as well as stakeholder responses. Research demonstrates the agency and resilience of migrants, who develop flexible solutions in the face of crisis.
While media and academic discussions of "climate refugees" paint a picture of mass displacement of millions, in reality many communities vulnerable to climate change may choose to stay as a result of strong cultural, historical, and spiritual attachments to place. This article explores this "voluntary immobility" and its implications in the Pacific Islands.
Nearly 4 million South Sudanese have been driven from their homes by violence or food insecurity since late 2013, roughly half seeking refuge in neighboring countries. Drought and conflict have converged in the young country to fuel one of the world's most severe humanitarian emergencies. This article examines refugee flows from South Sudan, underlying drivers, and regional and international responses to the crisis.
Climate-related displacement is not hypothetical: An average of 21.5 million people per year have been displaced since 2008 by natural disasters, and thousands more have fled slow-onset environmental hazards. While migration can serve as a safety valve to adapt to changing conditions, few orderly, legal channels exist for climate migrants (also known as environmental migrants), as this article explores.
