South African Civil Society Pushes Back Against Data Centre Expansion as Africa Confronts Digital Infrastructure Boom

Across South Africa, community groups and civil society organisations are mounting growing resistance to the rapid expansion of data centres, the vast warehouses of servers that power everything from streaming services to artificial intelligence. The facilities, which have proliferated in recent years, require enormous quantities of electricity, water and land — resources that critics argue are being diverted from local communities that can least afford the strain.

The pushback mirrors a broader global trend. As cloud computing and AI applications explode in demand, technology companies have raced to build ever-larger server farms across Africa, the Middle East and Asia. Data centres are often presented as engines of economic growth: they attract investment, create high-skilled jobs and improve digital connectivity. From Kenya to Nigeria to South Africa, governments have courted tech giants with tax incentives and cheap land, hoping to position their countries as regional digital hubs. South Africa has become one of the continent's most attractive destinations for such projects, with major international operators establishing a significant presence around Johannesburg, Cape Town and other urban centres.

Yet the physical footprint of these facilities is enormous. A single large data centre can consume as much electricity as tens of thousands of homes, rivaling the demand of entire small cities. The cooling systems that keep servers from overheating often rely on substantial volumes of water — a particularly sensitive issue in a country like South Africa, where drought and water scarcity have become recurrent crises in regions such as the Western Cape and Gauteng. Land use is another flashpoint: data centres are frequently built on large tracts of land that could otherwise be used for housing or agriculture, and their concentration in and around urban areas intensifies pressure on already strained infrastructure.

For many South Africans, the irony is difficult to ignore. The country suffers from chronic power shortages, with rolling blackouts having become a fact of daily life for millions of households and businesses. Yet data centres are frequently granted priority access to the grid and long-term power purchase agreements, effectively guaranteeing reliable electricity while ordinary citizens continue to endure outages. Water is similarly contested: municipalities often prioritise industrial users, leaving residents in some areas without dependable access to clean water.

Residents and activists who oppose new data centre developments point to a range of concerns. Some highlight the noise generated by cooling systems and backup generators, which can disturb nearby neighbourhoods day and night. Others raise questions about accountability: communities are rarely consulted before large facilities are approved, and the promised jobs — typically highly specialised positions — frequently go to a small number of skilled workers rather than local residents. In some cases, developers have reportedly secured favourable terms on land and utilities without transparent public debate.

The resistance in South Africa is part of a wider reckoning across the continent. In recent years, similar movements have emerged in Kenya, Ghana and Nigeria, where citizens have questioned whether the benefits of the digital economy are being distributed fairly. Data centres are only one component of a much larger infrastructure ecosystem — undersea cables, fibre-optic networks, substations and power plants — that is transforming the continent's physical and economic landscape. Proponents argue that this infrastructure is essential for Africa's digital future, enabling everything from mobile banking to telemedicine and remote education. Critics counter that without careful planning and community engagement, the boom risks deepening inequality and environmental degradation.

The debate has also drawn attention to the energy mix that powers these facilities. Data centres in South Africa rely heavily on the country's coal-dominated electricity grid, meaning that the digital economy is contributing to carbon emissions rather than helping to reduce them. Some operators have committed to powering their facilities with renewable energy, but such pledges often depend on the availability of green power — which remains limited in a grid still struggling to move away from coal. Solar and wind projects have expanded in recent years, yet they have not kept pace with demand from both industry and households.

Environmental advocates argue that data centre operators should be required to disclose their water and energy consumption, undergo environmental impact assessments, and contribute to local infrastructure upgrades. They also call for stronger oversight of the land deals and tax incentives that municipalities grant to attract investment. Without such safeguards, they warn, the costs of the digital boom will be borne by communities while the profits flow elsewhere.

The global context adds further urgency. The International Energy Agency has estimated that data centres worldwide could see their electricity consumption double by the end of the decade, driven largely by artificial intelligence and cryptocurrency mining. That trajectory has prompted scrutiny in Europe and North America as well, where local opposition has delayed or blocked projects. Africa's data centre market is smaller but growing fast, and the continent is now grappling with many of the same questions: Who benefits from digital infrastructure? Who bears its costs? And how can governments balance economic development against environmental and social priorities?

For South African civil society, the answer is clear: communities must have a meaningful say in decisions that affect their water, land and electricity. The pushback is not a rejection of digital progress, activists say, but a demand that it be pursued fairly. As more data centres break ground across the continent, that demand is likely to shape Africa's digital future as much as the technology itself. The coming years will test whether governments and operators can build the infrastructure of the twenty-first century without repeating the extractive patterns of the past.
