The total population is expected to double (Ndaw 2020), putting pressure on existing water infrastructure (UN DESA 2018). Climate change will have increasingly worse and unpredictable impacts on water, with cascading risks related to livelihoods, economies, health, and extreme weather events. Water Resilience in a Changing Urban Context: Framing Africa's Challenge and Pathways for Action 3 Highlights Without resilience to water scarcity, flooding, and climate disasters, current urban growth patterns and water management will not be sustainable. Most urban areas in Africa are confronting Alternatively, cities can provide new economic ▪ escalating water-related challenges opportunities and better livelihoods—but only if compounded by climate change and they build resilient systems that are better equipped projected growth.
