Digital Public Infrastructure: The Foundation Africa Cannot Afford to Skip

The DPI Imperative

The concept of Digital Public Infrastructure (DPI) has gained significant traction in global development discourse, but its practical implications for African governments remain poorly understood. DPI refers to the foundational digital systems — identity, payments, and data exchange — that enable a wide range of public and private applications to function efficiently.

India's experience with Aadhaar, UPI, and the Account Aggregator framework has demonstrated what becomes possible when DPI is in place: rapid financial inclusion, efficient social protection delivery, and a thriving digital economy built on open, interoperable foundations. The question for African governments is not whether to build DPI, but how to do so in ways that reflect African contexts, constraints, and governance realities.

The Three Pillars of DPI

Identity Infrastructure

A reliable, inclusive digital identity system is the foundation of everything else. Without it, governments cannot verify who they are serving, paying, or taxing. Revenue authorities cannot build comprehensive taxpayer profiles. Social protection programs cannot prevent duplicate payments. Financial institutions cannot meet KYC requirements efficiently.

Most African countries have some form of national identity system, but coverage rates vary enormously — from over 90% in some countries to under 40% in others. More importantly, most existing identity systems are not designed for digital integration: they lack APIs, cannot be queried in real-time, and are not connected to other government databases.

The investment required to build inclusive, interoperable digital identity infrastructure is significant — but the returns are even larger. A 2023 McKinsey analysis estimated that digital ID could unlock economic value equivalent to 3–13% of GDP in developing countries by 2030.

Payment Infrastructure

Africa has made remarkable progress in mobile money, with M-Pesa and its successors transforming financial access across the continent. But mobile money interoperability — the ability to send money seamlessly across different networks and to bank accounts — remains limited in many markets.

For governments, the payment infrastructure gap manifests in multiple ways: revenue collection that relies on cash or bank transfers rather than real-time digital payments; social protection disbursements that require physical distribution; and procurement payments that take weeks to process through manual banking systems.

Building interoperable payment infrastructure — connecting mobile money, banking, and government payment systems — is a prerequisite for efficient revenue collection, social protection delivery, and government procurement.

Data Exchange Infrastructure

The third pillar of DPI is the infrastructure that enables government agencies to share data securely and efficiently. Without it, every government application must build its own data integration — a massively inefficient duplication of effort that also creates security risks.

A government interoperability framework — a set of standards, APIs, and governance rules for inter-agency data sharing — enables revenue authorities to access customs data, social protection agencies to verify identity, and health systems to access insurance records. The efficiency gains are enormous: instead of each agency building bilateral integrations with every other agency, all agencies connect to a common exchange layer.

The African DPI Challenge

Building DPI in African contexts presents specific challenges that are often underestimated by international advisors:

Infrastructure constraints: Unreliable power and connectivity in many parts of the continent require DPI systems to be designed for offline operation and low-bandwidth environments.

Governance fragmentation: Many African countries have multiple competing identity systems — national ID, voter registration, passport, social security — that need to be rationalized or federated rather than replaced wholesale.

Trust deficits: In countries with histories of surveillance or data misuse, citizens may be reluctant to enroll in digital identity systems. Building trust requires transparent governance, clear data protection legislation, and meaningful civil society engagement.

Capacity constraints: Building and maintaining DPI requires sustained technical capacity that many African governments currently lack. This makes the choice of technology architecture — and the knowledge transfer approach — critical.

A Practical Path Forward

The most successful DPI implementations in Africa have shared several characteristics:

Start with a use case that delivers immediate value: Rather than building DPI as an abstract infrastructure project, successful implementations have anchored DPI development to a specific high-value use case — social protection delivery, revenue collection, or financial inclusion — that demonstrates tangible benefits quickly.

Build for federation, not replacement: Rather than attempting to replace existing identity systems, successful implementations have built federation layers that connect existing systems and gradually improve coverage and quality.

Invest in governance as much as technology: The governance framework for DPI — who controls it, how data is used, what rights citizens have — is as important as the technology. Countries that have invested in robust governance frameworks have built more durable and trusted DPI than those that focused exclusively on technology.

Plan for sustainability from day one: DPI is not a project — it is infrastructure that must be maintained, evolved, and funded indefinitely. Implementation plans that do not include a credible sustainability model are building on sand.

Implications for Government Digital Transformation

For African governments embarking on digital transformation, the DPI imperative has a clear practical implication: before investing in sector-specific applications — revenue systems, customs platforms, social protection registries — assess whether the foundational DPI layer is in place.

If it is not, the choice is not between building DPI and building applications. The choice is between building applications on a solid foundation or building them on sand — and then rebuilding them when the foundation eventually needs to be laid.

The governments that invest in DPI foundations now will find that every subsequent digital investment delivers more value, faster, and at lower cost. Those that skip the foundation will find themselves rebuilding the same applications repeatedly as the absence of foundational infrastructure becomes an increasingly binding constraint.

Conclusion

Digital Public Infrastructure is not a luxury for African governments — it is the prerequisite for the digital transformation that development goals demand. The investment is significant, but the returns — in revenue collection efficiency, service delivery quality, and economic growth — are transformational.

The question is not whether to build DPI, but how to build it in ways that are inclusive, trustworthy, and sustainable. Getting this right is one of the most important digital policy decisions African governments will make in this decade.
