Efforts to improve access to electricity and access to water and sanitation often go hand in hand, as they are essential components of sustainable development. By ensuring access to electricity, communities can have improved access to safe and reliable water supply and sanitation services, leading to better health outcomes, enhanced livelihoods, and overall development. This study investigates the effects of access to electricity on access to safely managed drinking water and sanitation services in 19 African countries from 2000 to 2020. Driscoll-Kraay standard errors and IV-GMM estimation techniques are used to estimate the relationship. The results show that access to electricity is positively associated with the percentage of people using safely managed clean water and sanitation services. The results also show that access to safely managed clean water and sanitation facilities in urban and rural areas turns out to be increased as far as access to electricity increases. The findings indicate that access to electricity reduces urban-rural inequalities in access to clean water and sanitation facilities. The sub-regional analyses conducted reveal that these findings are robust across SSA countries. Lastly, the findings reveal that GDP per capita, globalization, FDI and urbanization are channels through which access to electricity contributes to increasing access to safely managed water and sanitation services. African governments should implement policies that highlight the transformative potential of reliable electricity supply in ensuring sustainable and equitable access to clean water and proper sanitation facilities to safeguard public health and well-being.
改善电力供应以及改善水和卫生设施的努力往往相辅相成,因为它们是可持续发展的重要组成部分。通过确保电力供应,社区能够更好地获得安全可靠的供水和卫生服务,从而带来更好的健康成果、改善生计并推动整体发展。本研究调查了2000年至2020年期间19个非洲国家电力供应对安全管理的饮用水和卫生服务获取情况的影响。采用德里斯柯尔-克雷标准误差和工具变量广义矩估计技术来估计这种关系。结果表明,电力供应与使用安全管理的清洁水和卫生服务的人口百分比呈正相关。结果还表明,随着电力供应的增加,城乡地区安全管理的清洁水和卫生设施的获取情况也会增加。研究结果表明,电力供应减少了城乡在清洁水和卫生设施获取方面的不平等。进行的次区域分析表明,这些发现在撒哈拉以南非洲国家具有稳健性。最后,研究结果表明,人均国内生产总值、全球化、外国直接投资和城市化是电力供应有助于增加安全管理的水和卫生服务获取的渠道。非洲各国政府应实施相关政策,突出可靠电力供应在确保可持续和平等获取清洁水及适当卫生设施以保障公众健康和福祉方面的变革潜力。
