Water and cities
Cities globally can only raise and grow when they provide reliable access to water and sanitation, and when they can manage risks of too much, too little or too polluted water.
In OECD countries, cities have achieved high levels of protection against floods and storms, droughts, or water pollution, and a vast majority of city dwellers enjoy reliable water services. This remarkable achievement derives from distinctive combinations of infrastructures, business models and institutional arrangements. Whether and how these combinations are fit for future challenges is unclear.
