The 17th replenishment of the African Development Fund (ADF-17), the concessional financing window of the African Development Bank Group, concluded its final meeting on 15 and 16 December 2025 in London. During the session, development partners announced their financial commitments to support 37 low-income African countries, at a time when official development assistance faces growing fiscal pressures.
Since its creation in 1972, the African Development Fund has provided more than $45 billion in grants, low-interest loans, and guarantees to Africa’s least-developed countries. Its focus has been on building sustainable, climate-resilient infrastructure, strengthening governance and public financial management, and supporting debt sustainability. Over the years, the Fund has invested in infrastructure, social services, and home-grown solutions, evolving its priorities to address fragility, climate adaptation and mitigation, and private sector engagement. It operates on a three-year replenishment cycle, ensuring predictable and stable financing.
The London pledge session was crucial as it marked the adoption of the 2026–2028 financing programme. Co-hosted by the United Kingdom and Ghana, the meeting set strategic priorities in five key areas: jobs and livelihoods, energy access, trade and regional integration, debt sustainability, and institutional strengthening. The session also highlighted the Fund’s unique multilateral nature, co-owned by African and non-African member countries, with increasing direct financial contributions from African states, reinforcing ownership and shared responsibility.
The Fund provides affordable financing through grants, low-interest loans, and guarantees, allowing countries with limited fiscal space to invest in public goods without worsening debt vulnerabilities. Partner contributions through the replenishment process are combined with internal repayments and resources from the African Development Bank’s non-concessional window, enabling larger, transformative projects and mobilizing private capital in high-risk environments.
ADF-17 prioritizes projects aligned with national development plans and major continental challenges, including climate adaptation, food security, migration, and energy access. It supports strategic initiatives such as securing critical minerals for the energy transition, developing transformative trade corridors like the Lobito Corridor, and unlocking agribusiness potential. Since its inception, the Fund has financed over 3,000 projects, improving electricity access for 18 million people, food security for 90 million, transport infrastructure for 87 million, and safe water and sanitation for 48 million.
Despite its successes, the Fund faces challenges, including global resource scarcity, accelerating climate impacts, and political instability. The 17th replenishment introduced innovative financing mechanisms, including the market borrowing option, to enhance its capacity to mobilize additional resources while continuing to provide concessional support to the continent’s most vulnerable countries. This approach underscores the Fund’s commitment to expanding financial capacity and sustaining its role as a key development partner in Africa.
