African Development Fund (ADF)

The African Development Fund (ADF) is the concessional financing window of the African Development Bank Group, providing grants and low-interest loans to Africa's poorest countries and, crucially for international suppliers, opening procurement on those projects to firms from any country in the world.

What is African Development Fund (ADF)?

The African Development Bank Group operates two primary financing windows that carry different eligibility rules. The African Development Bank proper (the ADB window) lends to middle-income African countries and restricts procurement eligibility to firms from its regional member countries, meaning the 54 African nations. The African Development Fund is the separate concessional window that finances the poorest African countries. Because ADF projects are funded by contributions from donor countries worldwide, procurement is open universally, and firms from India, China, Germany, or any other country can bid alongside African companies.

This eligibility split catches many international bidders off guard. A project in Nigeria financed by the ADB window is accessible only to African firms, while an ADF-financed project in the same country opens the contract to global competition. Always identifying the funding source before investing time in bid preparation is therefore the first discipline for any firm targeting AfDB work.

The AfDB publishes procurement notices on its portal at afdb.org in both English and French, reflecting the Francophone and Anglophone character of its 54 regional member countries. The bank reached USD 11 billion in new investment commitments in 2024, a record, with a total portfolio of approximately USD 68.25 billion.

Why ADF matters for bidders

ADF-financed projects represent the broadest eligibility window in the AfDB system, and because many African markets have fewer established international competitors than World Bank or ADB markets, contract-by-contract win rates can be higher. The practical requirement is checking whether a specific project notice cites ADF, ADB, or NTF (Nigeria Trust Fund) as the funding source before committing to preparation, because the eligibility determination flows entirely from that label.

Example

A water treatment engineering firm based in South Korea sees a sanitation infrastructure notice on the AfDB portal for a project in Chad. Because Chad is one of Africa's lower-income countries, the project is ADF-financed, making the firm fully eligible to bid using icb procedures. Had the same firm looked at a project in South Africa funded through the ADB window, it would have been ineligible as a non-regional company.

Frequently Asked Questions

How do I know whether a project is ADF-funded or ADB-funded?

The procurement notice and project documentation on the AfDB portal at afdb.org identify the financing source. Look for ADF or ADB in the project financing section before assessing eligibility.

Can non-African companies bid on all AfDB procurement?

No. Only ADF-financed projects allow universal eligibility. ADB-window projects restrict bidding to firms from AfDB's 54 regional member (African) countries.

Does AfDB publish notices in French as well as English?

Yes. The AfDB publishes procurement notices in both English and French to serve Anglophone and Francophone Africa, so firms should monitor both language versions for complete coverage.
