Climate finance: what West Africa actually receives

Every climate summit ends with a headline figure, and every communiqué celebrates a rising volume. Yet from the vantage point of a West African finance ministry, the question is not how much the world pledges, but how much actually arrives, in what form, and at the price of what indebtedness. The region today receives a fraction of what it needs, mostly as loans that add to sovereign debt rather than financing resilience. The real issue is no longer the attractiveness of capital: it is the precise measurement of flows, at the level of the country, the sector and the instrument.

Rising volumes, a need out of reach

The continental diagnosis sets the order of magnitude. To implement its nationally determined contributions (NDCs), Africa needs about USD 2,800 billion between 2020 and 2030, close to USD 250 billion per year. In 2020, total flows, domestic and international combined, reached only USD 30 billion, barely 12% of the annual need. The trend then recovered: between 2021 and 2022, Africa captured about USD 43.7 billion in climate finance, up 48% from the USD 29.5 billion of 2019-2020. The trajectory is real, but it still covers only 23% of the annual needs linked to the NDCs.

For West Africa specifically, financing needs are estimated at USD 198.88 billion by 2030. To date, according to Oxfam, only 7% of this amount has been mobilized by wealthy countries and multilateral donors, roughly USD 13.92 billion. The unfunded gap approaches USD 185 billion. In other words, to reach the 2030 target, the pace of mobilization would need to be multiplied by an order of magnitude, not merely sustained.

The need is not a fate: what the adaptation trajectory shows

The slow pace of flows is in no way inevitable, and adaptation proves it. At the continental level, adaptation finance more than doubled, rising from USD 6.3 billion in 2017 to USD 14.8 billion in 2023. Over the same period, total climate finance to Africa rose from USD 29.5 to USD 43.7 billion. When political will and funding windows align, the curves climb fast: it is therefore not absorptive capacity that caps the system, but the tap upstream.

The problem is that these two curves, as upward as they are, start from a very low base and remain below the line of need. Africa's annual adaptation target is estimated at around USD 70 billion; adaptation flows actually received peaked at USD 13.8 billion in 2021-2022, about a fifth. The comparison over time serves as a compass here: it proves that acceleration is possible, while measuring the scale of the road still to travel.

Three countries concentrate the flows, yet fall far short

Nigeria, Ghana and Côte d'Ivoire are among the region's main recipients. According to Climate Policy Initiative, Nigeria is estimated to have received around USD 2.5 billion in 2021-2022, of which about USD 0.74 billion for adaptation (close to 30% of the total), a volume covering only a small share of its estimated adaptation needs. Ghana is estimated to have received on average close to USD 830 million per year over 2019-2020, split between adaptation and mitigation, against needs estimated in the billions. The concentration of flows on a few more structured economies thus masks a deficit that remains massive, even among the best-endowed.

Above all, what sets countries apart is not so much the volume received as the share of that finance taking the form of loans. In Niger, 51% of climate finance declared over 2013-2019 came through debt, against 43% in Mali, 41% in Burkina Faso and 40% in Ghana. The higher the loan share, the more climate aid weighs on states' debt trajectory rather than on their resilience.

The debt trap: why the form of finance decides its effect

The nature of the finance matters as much as its volume. Between 2013 and 2019, 62% of the USD 11.7 billion in climate finance declared by donors to West Africa took the form of loans rather than grants. The mechanics rest on three mutually reinforcing drivers. First, a structural effect: over the period, loans surged by 610% (from USD 243 million to USD 1.74 billion) while grants rose only 79%, so that the growth in flows is driven by debt. Second, a cost effect: at the continental level, 86% of climate finance comes from public actors (often lending development banks) against only 14% from the private sector, anchoring flows in repayable instruments. Finally, a ratchet effect: an adaptation loan finances an asset (dyke, irrigation, early warning) that generates no direct revenue to repay it, unlike a market-based mitigation project.

• A structural effect: loans grew by 610% over 2013-2019, against +79% for grants, in West Africa.
• A cost-of-capital effect: 86% of Africa's climate flows are public, often lending, against 14% private finance.
• A ratchet effect: adaptation produces non-market assets whose debt service weighs on the budget with no associated repayment revenue.

Benin illustrates the transition logic. In November 2024, the country received World Bank support of EUR 635.5 million, including an IDA credit of EUR 135.5 million and a EUR 200 million guarantee designed to mobilize up to EUR 500 million in commercial financing, aligned with its climate commitments and the Paris Agreement. The leverage effect is real, but it rests for the most part on debt and guarantees, not on grants. The consequence is budgetary before it is climatic: for a country whose fiscal space is already constrained, every borrowed adaptation dollar commits a fraction of future revenue to debt service, precisely when repeated climate shocks tend to compress those same revenues. Finance meant to strengthen resilience can thus, if poorly calibrated, undermine the sustainability of public finances.

When 62% of climate finance arrives as loans, adaptation aid becomes a driver of debt before it becomes a driver of resilience.

Adaptation, the poor relation: measuring the size of the gap

Adaptation is at once the region's vital priority and the worst-served component of the flows. Across Africa, only 20% of annual adaptation needs and 18% of mitigation needs were met in 2021-2022. Regional institutions are scaling up: the Green Climate Fund has already approved 19 projects in Côte d'Ivoire for USD 190 million in commitments. But domestic resource mobilization remains weak, and access to international windows remains a bottleneck for public policy.

The uncovered gap can be quantified. With an African adaptation need of about USD 70 billion per year and flows at USD 13.8 billion, the annual shortfall is close to USD 56 billion, four times what is currently mobilized. At the sub-Saharan level, the World Meteorological Organization places the cost of adaptation between USD 30 and 50 billion per year over the next decade, the equivalent of 2 to 3% of regional GDP. This is the order of magnitude of the effort to finance each year, and the measure of the step to be cleared.

The cost of inaction: what it costs not to finance

The debate on climate finance almost always centers on the spending to commit, rarely on the bill avoided. Yet inaction has a measurable price. According to the World Bank, climate change could cut the annual GDP of Sahel countries by 2 to 12% by 2050, and push an additional 13.5 million people into poverty by that horizon if nothing is done. The African Development Bank estimates that the continent already loses up to USD 15 billion per year because of climate, a loss that could climb toward USD 50 billion per year by 2050.

The cost is also paid in the present and in public accounts. The World Meteorological Organization notes that African countries lose on average 2 to 5% of their GDP each year because of climate hazards, and that some divert up to 9% of their budget to respond to climate extremes, resources taken away from health, education or infrastructure. The logic is implacable: underfunding adaptation today means financing repair tomorrow, more expensively, and most often still on credit.

This asymmetry should reverse the burden of proof in negotiations. As long as the debate is about the cost of adaptation, the requesting state is in the position of a supplicant. Once it documents the bill avoided, lost agricultural output, infrastructure rebuilding, flood-related health spending, it turns a request for aid into an investment proposal with a high social return. The cost of inaction is not a moral argument: it is an accounting datum that, properly costed, rebalances the relationship with donors and justifies concessional rather than costly finance.

What averages hide, and why fine-grained measurement changes the decision

An aggregate figure, 7% of needs met, 62% loans, USD 43.7 billion received, tells an average, not a field reality. Yet decisions are made at far finer levels than the regional average. A flattering national total can mask a concentration on one or two large urban mitigation projects, while rural areas exposed to drought see no disbursement at all. An announced adaptation volume can cover commitments signed but not disbursed, or loans reclassified as aid. This is precisely where the gap between a communiqué and a result is decided.

Three blind spots recur. The first is geographic: without geolocation of projects, it is impossible to know whether the money reaches the most vulnerable territories or concentrates on capitals. The second is temporal: a commitment is not a disbursement, and the gap between the two can reach several years. The third is qualitative: loan or grant, real adaptation or opportunistic label, the devil is in the definition. As long as these dimensions are not measured, steering remains blind.

You do not negotiate finance with a regional average. You negotiate it with a map of projects, a disbursement calendar and a loan/grant breakdown.

This is CRAD's conviction: disaggregated, geolocated and verified data is not a statistical refinement, it is an instrument of budgetary sovereignty. A state that knows precisely what it receives, where, when and in what form negotiates from a position of strength, steers flows toward its real priorities and grounds its trade-offs. Conversely, a state that has only aggregates is subject to the donors' accounting. Measuring climate flows finely, project by project, is the first step toward an adaptation policy that is steered rather than endured.

The gender blind spot: who finances those most affected?

Disaggregation also applies to gender, and the stakes are far from marginal. In sub-Saharan Africa, women produce a majority share of the food, on the order of 60 to 80% in low- and middle-income countries, and are on the front line facing climate shocks to agriculture. Yet they receive less than 10% of the credit granted to smallholders and a tiny share of extension services. Adaptation finance, when not explicitly targeted, follows existing channels and reproduces this gap.

The institutional signal confirms the blind spot: fewer than a third of countries that have drawn up a national adaptation plan explicitly integrate the gender dimension. For a region where agricultural resilience rests largely on women's labor, financing adaptation without targeting those most affected means financing partly off-target. This is exactly the kind of gap that disaggregated measurement makes visible, and therefore correctable. CRAD's work on the Gender Equality Index in ECOWAS energy SMEs (the WOCEWA project) shows that a fine-grained index turns a diffuse observation into a costed action plan.
