Summary of Climate Change and Migration: Evidence from the Middle East and North Africa by the World Bank

Core Content

This World Bank study explores the relationship between climate change, extreme weather events, and migration in the Middle East and North Africa (MENA) region. It is based on new household surveys and qualitative fieldwork conducted in 2011 in Algeria, Egypt, Morocco, Syria, and Yemen, as well as existing data from Morocco and Yemen. The report aims to provide empirical evidence on how households perceive climate change, how they are affected by weather shocks, what coping and adaptation strategies they employ, and how these factors influence migration decisions and remittance flows.

Main Findings

Perceptions of Climate Change

• Households in the MENA region are increasingly aware of climate changes, particularly in the last five years.
• Over 75% of households in the five focus countries believe that rainfall has become more erratic.
• Approximately 72% perceive that temperatures have risen.
• Many households report reduced rainfall, drier land, and less fertile soil, as well as changes in the timing and duration of the rainy season.
• Droughts are seen as more frequent, and these changes are associated with a range of negative impacts on agriculture, livestock, and water availability.

Impacts of Weather Shocks

• Weather shocks have a significant impact on households, especially in terms of income and crop losses.
• In Morocco, 62.2% of agricultural households reported reduced yields due to inadequate rainfall.
• Over 50% of households in the sample experienced at least one climate-related problem in the last five years.
• Poorer households are more likely to suffer from these shocks and have greater difficulty recovering from them.
• Wealthier households are 20 percentage points more likely to recover from weather shocks than poorer ones.

Coping and Adaptation Strategies

• Households primarily rely on savings, asset sales, and loans to cope with climate shocks.
• Selling livestock is a common strategy, with 40.6% of households reporting this.
• Some households withdraw children from school to cope with financial stress, with 36.4% doing so.
• Adaptation strategies include changes in agricultural practices, diversification of income sources, and migration.
• Community and government support is limited, and households often lack access to effective adaptation tools.

Migration Patterns and Drivers

• Climate change is not the main driver of migration in the MENA region, but it contributes to migration flows.
• Weather shocks are a significant factor in migration decisions, particularly in rural areas.
• Migration is often temporary, but some households opt for permanent relocation due to long-term environmental degradation.
• The study highlights that climate-related issues, such as droughts and changes in rainfall patterns, influence migration decisions.

Remittances and Climate Vulnerability

• Remittances are more likely to reach households in climate-affected areas, as these households are more prone to shocks and thus more likely to send money abroad.
• In Yemen, the analysis of remittance data suggests that remittances can alleviate poverty and improve human development indicators.
• However, the impact of remittances varies depending on the climate conditions of the receiving areas.

Key Information

• The study includes both quantitative and qualitative data, with focus groups and in-depth interviews conducted in both urban and rural areas.
• The methodology involves the use of household surveys and regression analysis to assess the correlation between climate variables and migration.
• The report emphasizes the need for better understanding of the interplay between climate change, migration, and socio-economic outcomes.
• It highlights the importance of improving community and government responses to climate change to support vulnerable households.

Structure of the Report

Part 1: Synthesis

• Chapter 1: Overview of climate change, migration, and adaptation in the MENA region.
  • Discusses the perception of climate change and its link to migration.
  • Highlights the limited capacity of households to recover from climate shocks.
  • Notes the role of government and community programs in adaptation.

Part 2: Focus Countries and Data

• Chapter 2: Selection of focus countries based on vulnerability to climate change.
  • Algeria, Egypt, Morocco, Syria, and Yemen were chosen due to their varying levels of climate vulnerability.
• Chapter 3: Details on the data collection methodology.
  • Describes the design of the household survey questionnaire.
  • Explains the sampling approach and the use of both quantitative and qualitative data.

Part 3: Impacts, Coping Strategies, and Adaptation Mechanisms

• Chapter 4: Perceptions of climate change and its impacts on households.
  • Presents data on how households in the five countries view climate changes.
  • Shows the distribution of perceptions using multiple correspondence analysis.
• Chapter 5: Examines the impact of weather shocks on households in Morocco.
  • Highlights the correlation between shock incidence and recovery ability.
  • Reveals that wealthier households are more resilient to climate shocks.
• Chapter 6: Explores coping and adaptation strategies used by households.
  • Discusses the diversity and limitations of these strategies.
  • Reviews community and government responses to climate change.

Part 4: Climate Change and Migration

• Chapter 7: Investigates whether environmental changes drive migration.
  • Finds that while climate change is not the main driver, it contributes to migration flows.
• Chapter 8: Uses qualitative data to explore the reasons for migration.
  • Highlights country-specific differences in migration motivations.
  • Includes testimonies from rural and urban respondents in Algeria and Yemen.
• Chapter 9: Focuses on Yemen and analyzes net internal migration.
  • Shows that climate conditions are a factor in migration decisions.
  • Provides evidence on the decomposition of migration variance.
• Chapter 10: Examines extreme weather events and their effect on migration in Morocco.
  • Demonstrates the correlation between weather shocks and migration likelihood.

Part 5: Remittances

• Chapter 11: Investigates whether remittances reach climate-affected households.
  • Evidence from Yemen suggests that remittances do reach these households.
• Chapter 12: Explores how remittances affect poverty and human development.
  • Finds that remittances have a positive impact, especially in areas with poor climate conditions.

Conclusion

• While climate change is not the primary cause of migration in the MENA region, it is a contributing factor.
• Weather shocks are more directly linked to migration decisions than climate change itself.
• Households in vulnerable areas are more likely to be affected by climate shocks and less able to recover.
• Coping strategies are limited and often insufficient.
• Remittances can play a supportive role in mitigating the effects of climate shocks, particularly in poor areas.
• The study calls for more research and policy attention to support climate adaptation and migration management in the region.
