We all know urbanization is important: Nearly 80% of gross domestic product is generated in cities around the world. Countries must get urbanization right if they want to reach middle- or high-income status.
But urbanization is challenging, especially because badly planned cities can hamper economic transformation and cities can become breeding grounds for poverty, slums and squalor and drivers of pollution, environmental degradation and greenhouse gas emissions.
That’s why it’s important for us to build cities that are livable, with people-centered approaches to urbanization and development. That will allow innovation and new ideas to emerge and enable economic growth, job creation and higher productivity, while also saving energy and managing natural resources, emissions and disaster risks. When the process is driven by people, it can lead to important results, the same way London and Los Angeles addressed their air pollution problems.
