Sub-Saharan African governments are grappling with the significant challenge of meeting growing citizen demands while simultaneously maintaining and improving their existing infrastructure assets. This predicament is exacerbated by financial constraints, subpar operations, and poor management afflicting publicly-owned utilities. Infrastructure development is undeniably pivotal for productivity and long-term economic growth, elevating living standards, alleviating poverty, and advancing sustainable development goals. Regrettably, infrastructure development in this region remains woefully inadequate, primarily due to the dominance of public sector investments. Attracting private investments has been challenging because of ongoing issues such as corruption, political instability, and money laundering. In light of the rising demand for infrastructure development and diminishing public budgets caused by global financial crises, innovative financing mechanisms have become an urgent necessity. This article delves into the potential of Public-Private Partnerships (hereinafter mentioned as ‘PPPs’) as an alternative approach to catalyse infrastructure development in sub-Saharan Africa. Amidst the backdrop of severe infrastructure deficits in developing countries, particularly in this region, PPPs have emerged as a promising avenue to enhance the efficient delivery of public services. However, their implementation is not without significant challenges. Drawing insights from the South African perspective, this article examines the legal framework of PPPs in South Africa and the multifaceted role and challenges faced in the implementation of PPPs. By shedding light on the potential and challenges of PPPs, this article aims to contribute to the discourse on sustainable infrastructure development in sub-Saharan Africa and provides insights for policymakers, investors, and stakeholders invested in the region’s socio-economic progress.
