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={David J. 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… 
Addressing Climate Migration: A Review of National Policy Approaches
ne of the most consequential human responses to climate change is and will continue to be the mass movement of people. Estimates of the extent of this migration vary widely, ranging from tens of
Climate anomalies, land degradation, and rural out-migration in Uganda
It is revealed that climate anomalies, rather than land degradation, are the primary contributor to environmental migration in Uganda, with heat stress of particular importance.
Climate-Induced Migration and Unemployment in Middle-Income Africa.
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 most
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 to
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 environmental
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 and
Modeling Human Migration Under Environmental Change: A Case Study of the Effect of Sea Level Rise in Bangladesh
Sea level rise (SLR) could have catastrophic consequences worldwide. More than 600 million people currently living in coastal areas may see their livelihood at risk and choose to migrate in the near
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.


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.
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.
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.
Natural disasters and population mobility in Bangladesh
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.
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 of
A universal model for predicting human migration under climate change: examining future sea level rise in Bangladesh
Climate change is expected to impact the habitability of many places around the world in significant and unprecedented ways in the coming decades. While previous studies have provided estimates of
