Financing Africa’s Urban Future

As Africa’s cities expand, the financing challenge is becoming a governance challenge: cities need more reliable revenues, better access to capital and stronger tools to turn growth into inclusive, resilient development.

Africa’s cities are growing rapidly – and so are their financing needs. As urbanisation accelerates, the continent faces an annual development financing gap of over US $400 billion. By 2030, Africa’s urban population is projected to reach 800 million, rising from about 49% to 58% of the total population. Closing this gap will require a shift from reliance on national grants to local tax reforms and blended public-private finance. But the challenge is not only about mobilising more money. Many local governments still lack the autonomy, technical capacity, and regulatory systems they need to manage large investments and long-term urban projects.

This means that the financing question is also a governance question: How can cities raise more of their own resources? How can they attract investment without increasing risks for residents? And how can urban development finance become more reliable, more inclusive, and more resilient?

Why city finance remains fragile

The African continent has an annual infrastructure financing gap of about $170 billion, much of it affecting cities directly. The barriers are well known, but they often reinforce each other: weak local revenue generation, limited fiscal autonomy, poor project pipelines, shallow capital markets, macroeconomic risks, and unequal access to climate finance.

Cities have weak local revenue bases because of outdated property registries, widespread informality, and low incomes. Weak land and property records reduce property tax collection, informality narrows the tax base, and urban poverty limits user fees and local taxes. Digitising property tax systems can help raise own-source revenue, reduce dependence on intergovernmental transfers, and improve local autonomy. And this is more than just a technical reform: it can also make local finance more transparent, predictable, and fair – if it is designed with residents’ ability to pay in mind.

Local governments need more room to act

Limited fiscal autonomy and intergovernmental constraints further weaken urban finance in Africa. Because central governments retain major tax powers, local authorities rely on uncertain national transfers. Many municipalities also lack borrowing authority, limiting long-term debt, bond issuance, and effective use of land assets. At the same time, overlapping statutory, communal, and customary land systems can make it difficult to use rising land values for public investment.

For cities, this creates a difficult situation: they are expected to provide services and infrastructure, but often do not control the financial tools needed to do so. Sustainable urban development therefore depends not only on additional funding, but also on clearer responsibilities and stronger local financial powers.

Good ideas need to become investable projects

African cities also face technical capacity and project bankability gaps. Many municipalities lack the expertise to prepare feasible, investment-ready projects and sometimes return unspent national funds because of weak budget execution. Fragmented planning worsens this, as outdated master plans often fail to keep pace with the rapid growth of informal settlements.

This matters because investors, development banks, and national governments need projects that are technically sound, financially viable, and socially responsible. Cities can partly respond by capturing value from urban expansion and partnering with the private sector – but these approaches must be designed carefully to manage risks and protect affordability. In other words, the problem is not only that cities need more finance. They also need the planning and preparation capacity to turn urgent urban needs into projects that can actually be funded and implemented.

Capital is available, but not always accessible

High risk perceptions and weak capital market access further undermine urban finance sustainability. Low credit ratings, shallow domestic markets, and risk-averse lenders make long-term borrowing difficult, while currency volatility, high public debt, and inflation further deter urban infrastructure investment. Some more creditworthy cities are increasingly using municipal and green bonds to finance climate-resilient infrastructure. These examples show that capital market access is possible – but usually only where cities have stronger financial management, clearer revenue streams, and an enabling regulatory framework.

Climate change has made sustainable urban development more urgent, especially in coastal and other highly exposed cities. Unequal access to climate finance remains a major challenge because municipalities often cannot access international funds directly, as these are channelled through national ministries. Funding is also highly concentrated: Africa receives limited climate finance overall, and about 40% of urban climate funding goes to just five countries. This creates a mismatch: many cities are on the front line of climate impacts, but they are not always in a position to access the finance needed to respond. Improving access to climate finance for municipalities is therefore essential for adaptation, resilience, and basic service delivery.

Why sustainable urban finance matters

Resilient, scalable urban financing in Africa and the wider Global South is essential to manage rapid urbanisation, close infrastructure gaps, and protect vulnerable communities from climate shocks. It also helps cities mobilise private capital, sustain basic services, and turn development projects into bankable long-term investments.

The shift to blended finance, land value capture, and municipal green bonds is driven by four factors. Public budgets for adaptation are limited. The costs of climate inaction are rising. Institutional investors need clearer ways to manage risks. And cities need stronger creditworthiness if they want to attract long-term capital. Cities that embed resilience in their budgets and balance sheets are better able to make that case to investors.

Moving beyond national grants

Institutions such as the African Development Bank and UNDP support African municipalities through blended finance, nature-based solutions, and resilience-focused projects, while organisations such as the Climate Policy Initiative track the local gains from closing urban investment gaps.

But sustainable urban finance cannot depend on individual projects alone. Building resilient and scalable urban finance in the Global South requires moving beyond national grants toward decentralised, creditworthy municipal systems. This means giving cities more fiscal autonomy, creating national frameworks to pool municipal investments, and using blended finance to de-risk private capital. It also means ensuring that finance supports inclusive urban development – not only projects that are attractive to investors.
