Advancing Africa’s Adaptation Finance Priorities Under the South African G20 Presidency

The document highlights a critical adaptation finance gap in Africa, noting that the continent requires between $187–359 billion annually but faces an 80% shortfall in adaptation investment. It identifies the South African G20 presidency as a strategic opportunity to shift climate finance from debt-creating loans to grants and concessional funding. Key recommendations include scaling locally led adaptation, implementing debt-for-climate swaps, and reforming Multilateral Development Banks (MDBs) to ensure at least 50% of climate finance for African Least Developed Countries is provided as grants or highly concessional finance.

• Africa is warming faster than the global average, with the Global Centre on Adaptation reporting a rate of 1.28°C, making it the fastest-warming region globally. This warming threatens food systems, biodiversity, water availability, and infrastructure, with projections suggesting crop yields could drop by up to 50% by 2050 without scaled-up adaptation investment.
• There is a massive disparity between Africa's adaptation finance needs and actual flows; the UNEP Adaptation Gap Report 2024 estimates an annual requirement of $187–359 billion, yet adaptation investment alone faces an 80% shortfall. Furthermore, much of the available finance is delivered as debt-creating loans, which increases fiscal stress for vulnerable economies.
• Implementation of adaptation funding through the Green Climate Fund (GCF) in Africa has been inefficient; while $3.5 billion was allocated to adaptation across 50 countries, only 27% of targeted beneficiaries were reached and only 1% progress was recorded regarding water resilience.
• The G20's Sustainable Finance Working Group (SFWG) currently employs a narrow framing of climate finance that prioritizes private sector mobilization and mitigation sectors like energy and industry, which overlooks Africa's heavy reliance on public and concessional sources for adaptation.
• The New Collective Quantified Goal (NCQG) is identified as the most critical climate finance negotiation for Africa. The African Group of Negotiators argues that the NCQG must prioritize equity, transparency, and a high share of non-debt-inducing instruments such as grants.
• Innovative financial tools like debt-for-climate swaps can reduce sovereign debt while funding resilience, as demonstrated by the Seychelles, which redirected over $22 million to conservation and adaptation by converting foreign debt into concessional local currency debt.
• Locally led adaptation models, such as Kenya's County Climate Change Funds (CCCFs) and the FLLoCA programme, show that institutionalizing climate finance at the subnational level—including allocating 2% of county development budgets to resilience—can effectively reach millions of people.
