Extreme weather events disproportionately affect residents of low-income urban settlements in the global South. This paper explores the impacts of extreme heat and flooding on water and electricity services in Accra and Tamale, Ghana. Interviews with water/electricity providers and water quality analysis are combined with household interviews, focus group discussions and observations conducted in eight low-income urban settlements. The findings highlight the interconnected nature of service provision during extreme weather events, with challenges in one sector reinforcing problems in another, exacerbating difficulties with access. Although households can utilize rainwater during flooding, it is highly susceptible to faecal contamination, and electricity supplies are often disconnected. During extreme heat, demand for water and electricity outstrips supply, leading to severe shortages, especially in Tamale. Water and electricity service providers should consider their interconnected nature and adopt a joined-up approach to cope with extreme weather events, which are predicted to increase with climate change.

极端天气事件严重影响了全球南方低收入城市居民区的居民。本文探讨了加纳阿克拉和塔马莱市极端高温和洪水对水和电力服务的影响。与水/电供应商的访谈和水质分析与家庭访谈，焦点小组讨论和在八个低收入城市居民区进行的观察相结合。调查结果突显了极端天气事件期间服务提供的相互联系的性质，一个部门的挑战加剧了另一个部门的问题，加剧了获取方面的困难。尽管家庭可以在洪水期间利用雨水，但雨水很容易受到粪便污染，并且经常断开电源。在高温下 对水和电力的需求超过了供应，导致严重短缺，特别是在塔马利。水和电服务提供商应考虑其相互联系的性质，并采取联合方式应对极端天气事件，预计极端天气事件将随着气候变化而增加。
