Exponential urbanisation is a huge challenge, but in cities are also the seeds of solution.
The world is urbanising at a staggering pace. In 1950, less than a third of the global population lived in cities. By 2010, half of the global population was urbanised. Now urbanisation is entering its most intense phase ever, with more than one million people migrating to cities every week. By 2050, three out of four of the world’s citizens will be living in cities.
