MENA Knowledge and Learning: Adaptation to a Changing Climate in the Arab Countries

Core Content

This document outlines the challenges and opportunities associated with climate change adaptation in the Arab countries, based on a 2012 World Bank report. It highlights the need for integrated, inclusive, and forward-looking strategies to address the increasing climate variability and its impacts on various sectors such as water, agriculture, urban development, tourism, and gender equity.

Main Points

1. Climate Change in the Arab Countries Today

• The Arab region is already experiencing higher temperatures and extreme weather events like droughts and flash floods.
• 2010 was the warmest year since the late 1800s, with 5 Arab countries setting new national temperature records.
• Over 90% of people in the region believe climate change is occurring and is largely due to human activities.
• 84% of respondents perceive it as a serious challenge for their countries.
• Public opinion is increasingly aware and supportive of climate action, especially among better-educated populations.

2. Water Scarcity and Climate Change

• The Arab region has the lowest freshwater endowment in the world, with only six countries not classified as water-scarce.
• Water scarcity is defined as less than 1,000 m³ per person per year.
• Climate change is expected to reduce water runoff by 10% by 2050.
• Water demand is projected to increase by 60% by 2045 due to population growth and increased usage.
• Aging infrastructure and lack of access in informal settlements exacerbate the problem.

3. Climate Change and Agricultural Production

• Agricultural production is expected to slow and may decline after 2050.
• The Mediterranean region, which supports 80% of the region's agricultural output, will face reduced rainfall and higher temperatures.
• This will increase water use and reduce crop productivity.
• Higher temperatures will affect pests, soil fertility, and the chilling requirements of some fruits.
• Agriculture is a major employer, with 40% of employment in the region tied to it.
• Rural poverty is significant, with 34% of the rural population living in poverty.

4. Arab Cities and Climate Change

• 56% of the Arab population currently lives in urban areas, and this is expected to rise to 75% by 2050.
• Droughts are driving rural-to-urban migration, especially in Syria.
• Urban areas are vulnerable to flash floods due to concrete surfaces, inadequate drainage, and construction in low-lying areas.
• Nighttime temperatures in cities are expected to rise by up to 3°C due to the urban heat island effect.
• Water supply in urban areas is under strain due to aging infrastructure and leakage.

5. Tourism and Climate Change

• Tourism contributes about 3% of GDP and 6% of employment in the region.
• Higher temperatures threaten the attractiveness of the Arab region for tourism.
• Long-term projections suggest that northern Mediterranean and European destinations will become more appealing.
• Climate change threatens cultural and natural assets, including ancient monuments, coral reefs, and snowfall in Lebanon.
• Ecotourism is growing, but ecosystems must be carefully managed to adapt to climate change.

6. Climate Change and Gender Equity

• Women are more vulnerable to climate change due to their roles in households and rural communities.
• They often take on additional responsibilities when men migrate to cities for work.
• Women face barriers such as limited access to education, credit, and legal authority.
• Only 9% of women are represented in Arab governments, below the global average.
• Empowering women is essential for effective adaptation and development.

7. Climate Change and Health

• Higher temperatures increase the risk of heat stress, strokes, and heart-related deaths.
• Warmer conditions expand the geographic range of disease vectors like mosquitoes.
• This increases exposure to diseases such as malaria and dengue.
• Climate change also threatens food security, leading to malnutrition and health issues, especially in vulnerable populations.

8. Socio-Economic Impact

• The impact of climate change varies depending on a country's development level.
• Six Arab countries are classified as least developed, with low GDP and high rural populations.
• Climate change is expected to reduce household incomes by 7% in Syria and Tunisia, and 24% in Yemen over the next 30-40 years.
• Poorer and less diverse economies are more vulnerable to climate impacts.

Key Recommendations

• Adaptation Pyramid: A framework for integrating climate change risks and opportunities into development planning, emphasizing adaptive management, leadership, and monitoring.
• Robust Decision Making: A method to identify adaptation options that work across multiple future scenarios.
• Public Access to Climate Data: Improve the availability of weather and water data to support informed policy decisions.
• Social Protection Measures: Enhance access to health care, education, and financial services to build resilience.
• Policy and Institutional Support: Develop climate-smart policies and ensure transparent, accountable governance.
• National Adaptation Strategies: Prioritize urgent adaptation needs and promote cooperation between government, civil society, the private sector, and international institutions.
• Financial Capacity Building: Strengthen the ability of Arab countries to assess and manage adaptation funding.

Conclusion

Climate change is not a static issue but a dynamic challenge requiring continuous adaptation. The Arab region must address its vulnerabilities through inclusive governance, investment in resilient infrastructure, and gender-sensitive policies. Political changes, such as those from the Arab Spring, can provide opportunities for more effective and participatory climate adaptation strategies.
