Civil society groups in South Africa are demanding an immediate halt to the construction of new hyperscale data centres, citing profound concerns over their escalating demand for water and electricity. Activists argue that these facilities, often developed by global tech giants, exacerbate existing resource scarcities in communities already struggling with inadequate access to essential services.
The pushback, particularly prominent in areas surrounding Cape Town, targets projects poised to consume vast amounts of power and water. Community organisations, such as the Philippi Horticultural Area (PHA) Food & Farming Campaign, have voiced alarm over the prospect of major data centres being built near townships like Khayelitsha, where thousands still lack reliable access to potable water and consistent electricity.
This growing opposition comes as South Africa grapples with a severe energy crisis, characterised by frequent loadshedding that disrupts economic activity and daily life across the country. Additionally, parts of the nation, including the Western Cape, face persistent water stress, making the high water usage of cooling systems in data centres a significant point of contention.
Hyperscale data centres, crucial for the continent’s burgeoning digital economy and the rollout of artificial intelligence services, require substantial infrastructure investment. Companies like Amazon Web Services (AWS) and Microsoft have significantly expanded their cloud regions in South Africa, viewing the nation as a strategic hub for serving the African market. However, their rapid expansion is now clashing with local environmental and social justice imperatives.
Activists are calling for comprehensive environmental and social impact assessments that genuinely consider the long-term strain on local resources and the equitable distribution of these resources among residents. They advocate for a moratorium on new builds until robust regulatory frameworks and sustainable resource management plans are firmly in place, ensuring that technological advancement does not come at the expense of community well-being.
Resource Scarcity and Economic Imperatives
The debate around data centres highlights a complex balancing act for South Africa: fostering digital economic growth versus addressing fundamental resource inequalities. Proponents of data centre development often point to the significant foreign direct investment, job creation (albeit often highly specialised), and the enablement of a robust digital infrastructure vital for startups, businesses, and government services.
However, critics counter that the economic benefits often do not trickle down sufficiently to compensate for the direct impact on local resource availability. A single hyperscale data centre can consume millions of litres of water annually, equivalent to the daily needs of thousands of households. The electricity demand can be staggering, potentially placing additional strain on Eskom’s already beleaguered grid, leading to increased loadshedding for residents and other industries.
The Department of Water and Sanitation has acknowledged the need for sustainable water management across all sectors, including industry. While the government is keen to attract foreign investment in technology, the growing public outcry could prompt a re-evaluation of permitting processes and environmental regulations specific to energy- and water-intensive industries.
Developers argue they are implementing advanced cooling technologies and sourcing renewable energy where possible to mitigate their environmental footprint. Yet, activists maintain that even with such measures, the sheer scale of planned expansion in a resource-constrained environment makes the projects unsustainable without stricter oversight and community consent.
The ongoing pushback is expected to intensify, potentially leading to legal challenges and increased pressure on municipal and national authorities to intervene. The outcome of this contest will likely shape future infrastructure development policies in South Africa, influencing how Africa balances its digital aspirations with its pressing environmental and social responsibilities. A resolution that respects both economic growth and community welfare remains a critical objective for all stakeholders.
