Summary of Pathways Out of the Polycrisis

Core Content

The Poverty, Prosperity, and Planet Report 2024: Pathways Out of the Polycrisis is a comprehensive analysis by the World Bank that addresses the intertwined challenges of poverty, inequality, and environmental sustainability. It outlines the current state of global poverty and shared prosperity, the impact of the pandemic and climate change, and the need for a differentiated, evidence-based approach to achieving sustainable development.

Main Messages

• Global Poverty Stagnation: Poverty reduction and shared prosperity progress have stalled since the pandemic, with extreme poverty still above pre-pandemic levels in the poorest countries.
• Shared Prosperity Challenges: Inequality remains a major obstacle to shared prosperity, with a significant number of economies still experiencing high levels of inequality.
• Climate Risks and Vulnerability: Climate change is a growing threat, particularly in poorer and conflict-affected regions, with limited progress in reducing vulnerability.
• Integrated Approach Required: Addressing poverty, prosperity, and environmental sustainability requires managing trade-offs and a holistic approach to data and policy.
• Policy Priorities Vary by Income Level: Poorer economies must focus on long-term growth, health, and education, while wealthier economies need to prioritize emissions reduction and economic transition.

Key Findings

Poverty and Shared Prosperity

• Stagnation in Poverty Reduction: After a period of rapid decline, global poverty reduction has slowed significantly, with the 2020s potentially becoming a "lost decade."
• Poverty Line Adjustments: The poverty line has been adjusted to reflect changes in global population and economic conditions.
• Regional Disparities: Most poor people are concentrated in Sub-Saharan Africa and South Asia, with extreme poverty rates still higher than in 2019 in these regions.
• Inequality Impact: High inequality hinders shared prosperity, and the number of economies with high inequality has decreased since 2000, but 1.7 billion people still live in such economies.
• Income and Prosperity Gap: The Global Prosperity Gap has not seen significant reduction since the pandemic, with the poorest economies lagging behind.

Climate and the Livable Planet

• Climate Risks: Extreme weather events have increased in frequency since 1970, and many people in poorer countries remain vulnerable to these risks.
• Vulnerability in Poorer Regions: Sub-Saharan Africa has the highest exposure to climate-related hazards, with over a third of its population at high risk.
• Emissions Trends: Global GHG emissions continue to grow, but economic activity has become less emissions-intensive over the past two decades.
• Energy Mix: Energy production remains heavily reliant on coal and petroleum, especially in poorer countries.
• Climate Adaptation Gaps: Poorer countries, particularly IDA-eligible ones, have limited capacity to adapt to climate change, while wealthier nations have made more progress.

Monitoring and Data

• Data Importance: Robust data is essential for tracking progress on the interlinked goals of poverty, prosperity, and the planet.
• Reproducibility: The report includes a reproducible research package for transparency and replicability.
• Measurement Tools: The Prosperity Gap and multidimensional poverty indices are used to better capture the depth and breadth of poverty and inequality.

Key Policies and Priorities

• Poorer Economies: Must prioritize long-term growth, investment in human and physical capital, and avoid carbon-intensive growth models.
• Lower-Middle-Income Economies: Should focus on growth, shared prosperity, and reducing emissions through efficient policies and climate resilience.
• Upper-Middle- and High-Income Economies: Need to lead in emissions reduction and manage the economic impacts of such measures.
• Global Cooperation: International collaboration is critical to ensuring that progress is inclusive and sustainable.

Authors and Contributors

The report was co-led by Maria Eugenia Genoni and Christoph Lakner, with support from a wide range of economists, researchers, and teams across the World Bank. Key contributors include:

• Henry Stemmler, Samuel Kofi Tetteh-Baah, and Nishant Yonzan as chapter co-leads.
• Global Poverty and Inequality Data Team, Data for Goals (D4G) Team, and World Bank's Regional Statistical Teams for ensuring data accuracy.
• Indermit S. Gill, Axel van Trotsenburg, and Deon Filmer for overall guidance and direction.

Conclusion

The report emphasizes that the world is at a critical juncture, with the need to address the polycrisis of poverty, inequality, and climate change. It provides a framework for managing trade-offs and achieving progress on all three fronts, highlighting the importance of data, policy coherence, and international cooperation. The path out of the polycrisis is clear but requires sustained effort, strategic investment, and a renewed focus on equity and sustainability.
