The document examines 'technological leapfrogging' in Africa, focusing on how decentralised renewable energy, mobile finance, and artificial intelligence can overcome infrastructure deficits. It presents a 'Large Infrastructure and Leapfrogging' scenario projecting significant GDP growth and poverty reduction by 2050, while providing policy recommendations to address structural bottlenecks in skills, financing, and regulation.

The Large Infrastructure and Leapfrogging scenario presents an optimistic pathway for Africa, benchmarking progress against historical trajectories in South Asia and South America. It focuses on accelerating the transition to modern energy systems and expanding digital connectivity to drive productivity and social benefits by 2050.

The document examines the critical role of infrastructure in Africa's development, highlighting a persistent deficit that constrains GDP growth and productivity. It argues that closing this gap, which requires over US$100 billion annually, is essential for the success of the African Continental Free Trade Area (AfCFTA) and for shifting the continent toward a more inclusive growth trajectory.

The document argues that AI represents a frontier for technological leapfrogging in Africa, capable of bypassing traditional constraints in education, healthcare, and governance. It highlights the potential for inclusive AI deployment to add US$ 1 trillion to the continent's GDP by 2035, particularly in sectors like agriculture and finance. A key example is provided by the South African Revenue Service (SARS), which uses AI to shift tax administration from reactive enforcement to proactive compliance. However, the document notes that realizing this potential requires addressing gaps in computing infrastructure, digital skills, and regulatory frameworks. To support this, the AI 10 Billion Initiative aims to mobilize US$ 10 billion by 2035 to invest in AI infrastructure and skills, targeting the creation of up to 40 million jobs.

The report outlines the 'Large Infrastructure and Leapfrogging' scenario, which models the effects of targeted infrastructure investment in Africa from 2027 to 2050. It emphasizes the synergy between large-scale renewable energy, off-grid solutions, and ICT to lower barriers for private capital and formalize the informal economy. The analysis uses the International Futures (IFs) platform to categorize spending across traditional, ICT, and other infrastructure, benchmarking progress against developing regions in South Asia and South America.

As of 2022, 41.5% of Africa's population lacked electricity, with sub-Saharan Africa lagging significantly at 51.5% access. The document argues that traditional grid expansion is too slow and expensive for rural areas, proposing a 'leapfrog' strategy centered on solar-based off-grid and mini-grid solutions. World Bank estimates suggest that providing electricity to 380 million people by 2030 would require over 160,000 mini-grids costing approximately US$ 91 billion. Despite possessing 60% of the world's best solar resources, Africa faces severe financing shortfalls, with clean energy finance growing by only 2.5% in sub-Saharan Africa between 2021 and 2022, compared to over 100% in Latin America. Barriers to deployment include high public debt, regulatory bottlenecks, and shifting geopolitical priorities, such as the end of the US Power Africa initiative.

The document examines how frontier technologies enable developing countries, particularly in Africa, to bypass costly traditional infrastructure. It highlights the use of drones for precision agriculture in Mozambique and medical logistics in Rwanda, as well as the application of the Internet of Things for water safety in Bangladesh and the increasing accessibility of small-scale satellites for urban planning and land-use monitoring.

The report highlights the impact of corruption and inefficiency on energy projects in South Africa and the DR Congo. In South Africa, the Medupi and Kusile coal plants suffered from massive cost overruns and delays, contributing to unsustainable debt for Eskom and frequent blackouts, though performance improved by 2025. In the DR Congo, the Grand Inga Hydropower Project, specifically Inga III, has been delayed for decades due to funding and transparency issues, leaving the country with unreliable electricity despite significant hydropower potential.

Africa has experienced significant technological leapfrogging by bypassing fixed-line telecommunications in favor of mobile networks. While mobile subscriptions surged from 1.9 to over 100 per 100 people between 2000 and 2023, fixed broadband remains limited. The report highlights the role of satellite internet, such as Starlink, in reaching remote areas and notes that mobile broadband coverage in Nigeria is linked to increased household consumption and poverty reduction. By 2050, mobile phone and mobile broadband subscriptions are projected to reach 150 and 149 per 100 people, respectively, though gaps in affordability and digital skills persist.

The research paper examines the 'fintech revolution' in Africa, focusing on how mobile money services like M-Pesa have allowed the continent to bypass traditional banking infrastructure. It details the economic impacts of digital finance, including poverty reduction and GDP growth in sub-Saharan Africa, while noting remaining challenges in cross-border payments and regulatory oversight.

Africa faces a significant infrastructure deficit, with an annual funding shortfall of US$68–108 billion. The report examines the role of the Programme for Infrastructure Development in Africa (PIDA), the potential of domestic capital—estimated at over US$1.1 trillion—and the challenges of public-private partnerships. It highlights that up to 90% of projects fail before financial close due to poor early-stage preparation, arguing for better project bankability and risk-sharing instruments to attract private investment.

Africa's infrastructure spending is robust relative to GDP but insufficient given population growth, with financing heavily reliant on governments and development partners. Public investment is severely constrained by high sovereign debt, with debt servicing costs often exceeding infrastructure spending. Private investment remains low due to high capital costs and risk perceptions, though specific countries like South Africa and Egypt have seen success through targeted policy frameworks. Development finance is also facing a decline due to geopolitical and macroeconomic pressures.

The Large Infrastructure and Leapfrogging scenario is projected to accelerate Africa's average annual economic growth to 6% between 2027 and 2050, resulting in a total GDP nearly US$1 trillion higher than the baseline by 2050. This trajectory is expected to increase average GDP per capita by approximately US$510 and reduce the number of people in extreme poverty by 63 million, bringing the poverty rate down to 11.5% by 2050.

The document defines development leapfrogging as the ability of developing economies to skip intermediate technological stages and move directly to advanced systems. It argues that Africa is uniquely positioned for this due to limited legacy infrastructure, which reduces 'path dependency' and allows for the adoption of decentralised and digital solutions. Key examples include mobile finance, solar mini-grids, and the use of AI in agriculture and health. However, the document notes that full realisation of this potential depends on enabling conditions such as regulatory frameworks, digital infrastructure, and skilled human capital.

The research paper argues that Africa's infrastructure deficit is a cumulative result of colonial-era designs focused on extraction, post-independence mismanagement, and the impact of 1980s debt crises and Structural Adjustment Programs. It notes that colonial railways shaped current urban locations and that recent investments have often focused on prestige projects or specific corridors funded by external partners like China.

The paper examines the role of technological leapfrogging in transitioning Africa's large informal economy into the formal sector. It highlights that in 2024, the informal sector accounted for 58% of the labour force and 27% of GDP, with projections suggesting a decline to 50% of the labour force and 24% of GDP by 2050. The author identifies digital ID systems as the critical first step for formalisation, noting that roughly half of the world's one billion people without official identification live in Africa. The document asserts that digitisation—including biometric IDs, mobile payment solutions, and PAYG models—can expand the tax base and improve access to credit and social protections without imposing heavy compliance costs on small-scale operators.

Africa has seen infrastructure improvements, particularly in sub-Saharan Africa, but continues to face a substantial deficit driven by population growth and urbanisation. Financing is characterized by a tension between concessional Western multilateral loans and more commercial, opaque Chinese lending via the Belt and Road Initiative. Recent efforts, such as the PIDA framework and the 2025 Africa Infrastructure Financing Summit, aim to align investment with pan-African priorities and global sustainability goals, including a transition toward renewables and electric mobility.

The analysis compares two scenarios for African infrastructure financing up to 2050. Under the 'Large Infrastructure and Leapfrogging' scenario, government spending is projected to reach US$267 billion by 2050, exceeding the 'Current Path' forecast by US$44 billion. Average annual public spending from 2027 to 2050 is expected to be US$171 billion in this scenario, compared to US$150 billion under the Current Path.

The document introduces a social impact framework developed by the NBSPLUS project to improve the intentional design and assessment of nature-based solutions (NbS). It defines NbS as the use of natural processes and blue-green infrastructure—including parks, wetlands, green roofs, and restored waterways—to tackle climate, biodiversity, and societal challenges. The framework categorizes social impacts into several dimensions, including physical and mental health, recreational value, place attachment, knowledge and learning, pro-environmental behavior, social cohesion, justice (recognitional, distributive, and procedural), economic value, food security, and empowerment.

The document critiques the South African Reserve Bank's (SARB) restrictive interest-rate cycle and its shift toward a lower inflation target, arguing that such policies prioritize price stability over sustainable growth and employment. It proposes a more 'developmental' approach to monetary policy, including a 'look-through' rule for supply shocks and targeted funding tools for productive sectors.
