The world is undergoing an unprecedented and irreversible wave of urbanization, with the share of the global population living in cities set to reach 60% by 2030. But rapid urbanization is driving up industrial fossil-fuel consumption and household water consumption, and is increasing demand for food in areas where arable land is scarce.
