Adaptation Gap Report 2024: Executive Summary

Core Message: Despite increased international adaptation finance and some progress in planning and implementation, a significant adaptation finance gap persists. This threatens efforts to build climate resilience globally, particularly affecting the world's most vulnerable populations. While adaptation is critical to avoid escalating climate impacts, current financing, planning, and implementation fall short.

Key Findings Across Chapters

Chapter 1: Policy & Scientific Context

• Urgent Need: Climate change impacts are intensifying rapidly, with adaptation action falling behind required pace to meet goals.
• Global Goal on Adaptation (GGA): COP 29 (Baku) must establish a New Collective Quantified Goal (NCQG) for finance by 2025. Even if doubled, adaptation finance may only slightly close the gap.
• Paris Agreement Aim: Keep global warming "well below 2°C" aims unrealistic under current policies; adaptation is becoming urgent regardless.

Chapter 2: Global Progress on Adaptation Planning

• NAP Adoption: 87% of developing countries have National Adaptation Plans (NAPs), but 10% lag despite slow progress overall.
• NAP Effectiveness: Mixed quality exists; many plans lack:
  • Robust evidence for planning
  • Clear implementation pathways
  • Adequate vulnerability/risk assessments
  • Inclusivity of marginalized groups (especially women)
• NDC-NAP Alignment: About 68% of countries link NDC adaptation components to NAPs, but alignment remains a challenge.

Chapter 3: Implementation

• Progress is Slow: Few cities systematically track adaptation actions beyond design.
• Project Effectiveness: Efforts vary widely; core barriers include:
  • Lack of M&E frameworks
  • Insufficient capacity to implement
  • Governance hurdles limiting progress
  • Financing mismatches requiring concessional finance
• Monitoring Deficits: Most progress reports provide sectoral analysis but lack MEL systems to track effectiveness.

Chapter 4: Adaptation Finance Gap

• Huge Gap Remains: Estimated costs ($215-387 billion/year for developing countries) far exceed funding flows ($27.5 billion/yr).
• Type Matters: Easier finance for reactive, incremental adaptation; harder for anticipatory/transformative actions or non-market sectors (e.g., water, agriculture).
• Targeting: Vulnerable countries (LDCs/SIDS) receive more favorable financing, but gaps persist across scales (subnational/local).
• Private Sector Need: Crucial but currently underestimated. Enabling factors include taxonomies, standardized climate finance reporting, and national funds.

Chapter 5: Capacity-Building & Technology Transfer

• Deep Interdependence: Capacity-building (soft skills) and technology transfer (hard tools) mutually reinforce adaptation effectiveness.
• Priority Areas: Focus heavily on water and agriculture, but need broader application.
• Feedback Loop: Successful technology uptake requires concurrent capacity development.
• Recommendations: Strengthen leadership, train officials, enable South-South exchange, use blended finance, and base planning on country-specific needs.
• Inclusive Approach: Integrate gender equity and social inclusion throughout initiatives to avoid maladaptation.

Cross-Cutting Insights

• Global Coordination: Needed to coordinate finance, planning, and implementation synergistically under the NCQG.
• Adaptation Types: Must move from coping mechanisms to anticipatory, systemic transformation (e.g., nature-based solutions).
• Who Pays Critically: Current flows burden the poorest via debt/repayment burdens, challenging climate justice principles.
• Monitoring Gaps: URGENT need for better MEL systems to track adaptation outcomes and co-benefits.
