Digitalisation and Sustainability in South Africa: A Systematic Review Exploring Tensions, Synergies, and Developmental Contradictions
In South Africa, escalating consumption of digital devices poses significant threats to ecological sustainability and has far-reaching implications for environmental degradation. The ratio of digital devices to human beings is rapidly increasing, underscoring the urgency of interrogating the sustainability implications of digital expansion. This study investigated the complex relationship between digitalisation and sustainable development, focusing on the social, environmental, and economic impacts in the South African context. For this systematic review, researchers synthesised and analysed the findings of 44 articles, published between 2015 and 2025. Using a knowledge–implementation–effect (K-I-E) cycle, the research sought to bridge knowledge gaps, critically assess the ecological costs of digital innovation, and explore how digital technologies align or conflict with sustainability goals. The study hypothesised that unchecked digitalisation exacerbates climate vulnerability, e-waste, and energy consumption, thereby threatening environmental integrity and social equity. The findings underscore the digitalisation–carbon footprint paradox, capturing a contradiction of the digital age, whereby technological progress helps reduce environmental impact and at the same time drives new forms of environmental pressure. This paradox reflects a tension between efficiency gains and expanded energy consumption. The study has major implications for policymakers because it promotes eco-friendly principles. Notably, there is a paucity of literature on digitalisation and sustainability in South Africa, with existing studies largely confined to narrow, sector-specific analyses rather than providing integrated, systemic, and cross-sectoral perspectives.
