Climate Change is big news all over the world. Ironically, water usually finds mention in the footnotes even though it is arguably the principal adverse fall-out of changing climate patterns and extreme weather events. Since 2008, more than half of the world’s population already lived in cities. This figure continues to grow, particularly in Africa and Asia, and coastal urban centres receive a disproportionate share of this growth. Urbanization can be a positive force, however safe, adequate, and predictable water supplies are a necessary feature of sustainable urban development.
