The impact of climate change on migration: a synthesis of recent empirical insights

  title={The impact of climate change on migration: a synthesis of recent empirical insights},
  author={D. Kaczan and Jennifer Orgill-Meyer},
  journal={Climatic Change},
Concern about the human impact of climate change has led to predictions of how people living in areas vulnerable to drought, flood, and temperature changes will respond to such events. Early studies warned that climate change would lead to dramatic increases in human migration as households became unable to adapt to the impacts of climate change. More recently, empirical studies focused on observed climate events and trends have documented how migration flows vary as a function of both the… Expand

Climate anomalies, land degradation, and rural out-migration in Uganda
Globally, rural livelihoods are increasingly challenged by the dual threats of land degradation and climate change. These issues are of particular concern in sub-Saharan Africa, where landExpand
Climate-Induced Migration and Unemployment in Middle-Income Africa.
It is shown that climate anomalies affect mobility in all three countries, and country-specific findings highlight the contextually-specific nature of climate-migration relationships, and do not support claims that climate change is widely contributing to urbanization across Africa. Expand
Migration management to reduce the risk of climate change: government perspective
This research is driven by the phenomenon of the increasing trend of population migration from agricultural and coastal areas due to climate change. The impact of climate change that is felt mostExpand
Connecting the dots between climate change, household water insecurity, and migration
Climate change is now considered a primary global driver of migration, with water insecurity theorized to be a key determinant. Most studies have focused on large-scale climate migration eventsExpand
Comparing climate change perceptions and meteorological data in rural West Africa to improve the understanding of household decisions to migrate
Largely dependent on rain-fed agriculture, the West African populations could be severely impacted by climate change and variability. In this paper, we performed a literature review relating toExpand
Environmental migration and sustainable development of regions and countries
Our paper focuses on studying the development and implementation of a comprehensive environmental safety assessment and mitigation strategy for countries of origin and destination of environmentalExpand
Sensitivity of seasonal migration to climatic variability in central India
Extreme climatic events and variability are on the rise around the world, with varying implications for populations across socio-economic conditions. Effective strategies for climate adaptation andExpand
Climatic conditions are weak predictors of asylum migration
Results from a machine-learning prediction framework reveal that drought and temperature anomalies are weak predictors of asylum migration, challenging simplistic notions of climate-driven refugee flows. Expand
Weather, Climate, and Migration in the United States
Do people move as a result of temperature shocks? Documenting weather as a push factor for migration is crucial for informing policy related to climate change and adaptation. This paper studies theExpand
Climate change, migration and voice
Climate change is frequently predicted to result in dramatic increases in international migration, yet current research has largely failed to identify such movements in practice. This paper shedsExpand


Country-specific effects of climate variability on human migration
It is revealed that climate variability has country-specific effects on migration: Migration tends to increase with temperature anomaly in Uganda, tends to decrease with temperature anomalies in Kenya and Burkina Faso, and shows no consistent relationship with temperature in Nigeria and Senegal.

Environmental Influences on Human Migration in Rural Ecuador
The results indicate that adverse environmental conditions do not consistently increase rural out-migration and, in some cases, reduce migration, and support an alternative narrative of environmentally induced migration that recognizes the adaptability of rural households in responding to environmental change. Expand
Heterogeneous climate effects on human migration in Indonesia
The effect of anomalous temperatures, rainfall levels, and monsoon timing on migration outcomes in Indonesia and the sensitivity of estimates to alternative climate and migration measures is examined to highlight the heterogeneous use of migration as a response to such changes. Expand
Migration in the context of vulnerability and adaptation to climate change: insights from analogues.
Review of case studies of dry-season migration in the West African Sahel, hurricane-related population displacements in the Caribbean basin, winter migration of 'snowbirds' to the US Sun-belt, and 1930s drought migration on the North American Great Plains explore the interaction of climate change and vulnerability.

The results indicate that flooding has modest effects on mobility that are most visible at moderate intensities and for women and the poor and point toward an alternate paradigm of disaster-induced mobility that recognizes the significant barriers to migration for vulnerable households as well their substantial local adaptive capacity.

Nonlinear permanent migration response to climatic variations but minimal response to disasters
The results suggest that permanent migration is influenced by climatic variations, whereas episodic disasters tend to have much smaller or no impact on such migration. Expand
Perceptions of environmental change and migration decisions
While climate change is projected to increase displacement of people, knowledge on this issue remains limited and fragmented. In his paper we focus on the micro-level and study the effects ofExpand
The effect of environmental change on human migration
The influence of the environment and environmental change is largely unrepresented in standard theories of migration, whilst recent debates on climate change and migration focus almost entirely onExpand
Migration and household adaptation to climate: A review of empirical research
Abstract This paper reviews empirical research on migration and land use impacts associated with climate change. Household migration arises due to changes in economic opportunities and climateExpand
Migration and Climate Change: An Overview
Climate change has become a major concern for the international community. Among its consequences, its impact on migration is the object of increasing attention from both policy-makers andExpand
