Africa is vulnerable to a diverse range of climate change hazards that have significant impacts on food security, biodiversity loss, water crises and prevalence of infectious diseases. With much of the continent’s population reliant on ecosystems to sustain their livelihoods, degradation of ecosystems caused by both climatic and non-climatic stressors is increasing vulnerability, reducing adaptation potential and limiting progress towards achieving the Sustainable Development Goals. Ecosystem-based adaptation (EbA) presents a critical opportunity to address complex climate change vulnerabilities and mitigate greenhouse gas emissions across Africa. This study examines both the proposed extent of EbA actions across Africa and assesses alignment with existing research on EbA actions. A quantitative assessment of 52 Nationally Determined Contributions together with a review of available academic literature is undertaken. Results show that out of the 713 individual adaptation actions, 36.2% can be classified as EbA. The four sectors of agriculture, environment, forestry/land use and land use change, and water contribute ~ 82.5% of the total number of EbA actions identified across the continent. The meta-analysis revealed that 58% of EbA-focused research papers explicitly address or reference mitigation co-benefits. However, research on EbA actions focuses on mitigation and adaptation independently with little focus on integration of these outcomes. Understanding the current status of EbA and its integration of mitigation and adaptation provides a solid foundation for scaling up efforts to adapt to the current and impending impacts of climate change across Africa. Limited resources necessitate a structured and programmatic approach towards scaling up the implementation of EbA mitigation synergies.
