Abstract
Background: Rolling blackouts (planned power outages) are common in low- and middle-income countries, including South Africa. Recently, South Africa has experienced longer and more frequent rolling blackouts owing to its reliance on an aging electricity grid, among other challenges. During rolling blackouts, parts of the electricity grid are shut down, and the loss of power in homes, businesses, and industries across vast areas leads to a breakdown of key amenities required for environmental health.
Objectives: This commentary contextualizes the existing consequences and potential implications of rolling blackouts for environmental health in South Africa.
Discussion: We examined key areas where rolling blackouts affect environmental health, including water and sanitation, air quality, food safety, and socioeconomic challenges. Power outages have led to contamination of freshwater bodies with raw sewage due to resultant interruptions of wastewater treatment works. The use of generators and burning of dirty fuels during blackouts have added to outdoor and household air pollution. Rolling blackouts also expose people to unsafe food. Finally, we discuss some ways forward and the benefits of using renewable energy sources. A critical evaluation of these impacts underscores the urgent need for more sustainable energy solutions that safeguard environmental health in South Africa. https://doi.org/10.1289/JHP1090.
期刊介绍:
The Journal of Health and Pollution (JH&P) was initiated with funding from the European Union and World Bank and continues to be a Platinum Open Access Journal. There are no publication or viewing charges. That is, there are no charges to readers or authors. Upon peer-review and acceptance, all articles are made available online. The high-ranking editorial board is comprised of active members who participate in JH&P submissions and editorial policies. The Journal of Health and Pollution welcomes manuscripts based on original research as well as findings from re-interpretation and examination of existing data. JH&P focuses on point source pollution, related health impacts, environmental control and remediation technology. JH&P also has an interest in ambient and indoor pollution. Pollutants of particular interest include heavy metals, pesticides, radionuclides, dioxins, polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds (VOCs), air particulates (PM10 and PM2.5), and other severe and persistent toxins. JH&P emphasizes work relating directly to low and middle-income countries, however relevant work relating to high-income countries will be considered on a case-by-case basis.
