Executive Summary

The report, "Growing Resilience," examines nature-based solutions (NBS) in sub-Saharan Africa (SSA) for enhancing climate resilience. From 2012 to 2023, NBS project initiation grew at an average annual rate of 15%, with over $12.5 billion in funding raised. These projects address climate hazards (e.g., floods, droughts) and co-benefits such as improved water quality, job creation, and biodiversity protection. Africa's vulnerability, exacerbated by rapid urbanization, fragility, and financial constraints, underscores the need for NBS. Barriers include policy gaps and limited technical capacity. Key recommendations include integrating NBS into national policies, improving project preparation, diversifying funding sources like grants and green bonds, enhancing monitoring and evaluation, and tailoring strategies to national contexts.

Key Findings on NBS Projects

• Growth and Funding: Project initiation increased steadily, with MDBs like the World Bank and African Development Bank dominating funding. Total funding secured for NBS was $12.5 billion.
• Common Objectives: Most projects aimed at flood mitigation, improved water quality, and erosion control, often integrating green and gray infrastructure.
• Geography and Developers: Projects focused on rural and coastal areas, led primarily by governments and NGOs, often in collaboration with multilateral organizations.
• Funding Sources: Grants and concessional loans were key, with emerging use of instruments like carbon credits and PES schemes.

Key Barriers and Strategies

• Barriers: Lack of supportive policies, institutional buy-in, technical capacity, data, and adequate funding; social issues like insecure land tenure.
• Strategies: Align policies with NBS, enhance project preparation facilities, promote gender equity and Indigenous knowledge, develop business cases, and expand innovative financing tools.

Recommendations

1. Integrate NBS into relevant policies and plans across SSA to institutionalize their role in addressing climate and development challenges.
2. Improve project preparation and NBS-specific technical capacity to develop a project pipeline.
3. Enhance project integrity and effectiveness by incorporating gender equity and Indigenous traditional knowledge, increasing responsiveness to community needs, and safeguarding biodiversity.
4. Diversify funders and funding sources using conventional and innovative financial mechanisms.
5. Apply country-level implementation strategies based on natural hazards, fragility, and climate impacts.
6. Improve monitoring, evaluation, and learning to ensure projects deliver intended climate impacts and co-benefits.

Conclusion

NBS offer significant potential to address climate resilience and development needs in SSA, but systemic changes, increased investment, and tailored strategies are essential to scale their implementation effectively.
