More than half the world’s population today live in cities, and another 2.5 billion people are expected to join them by 2050. The frequency of torrential rain and storm surges is on the rise in big, densely populated cities like New York, Mumbai and Jakarta, hitting those living in marginalised, informal settlements like slums the hardest. Desertification swallows arable land needed to feed swelling urban populations. And sea level rise threatens everyone living in coastal areas, delta regions, and small-island countries.
