City experiment fund: the system transformation our cities need

Cities occupy only about 2% of Earth’s land area, but house between 60–85% of the world population. At a time of accelerated change — and with complex issues such as climate change, migration and inequalities challenging our ability to respond, cities are emerging as leaders. Because cities concentrate development challenges — access to services, participation in decisions, distribution of water and electricity — they also become a laboratory on how these can be addressed.
