Urban Development

Tackling the challenges of the city

The urbanization trend is Global. Today, 54 percent of the population lives in urban areas. And this increase is expected to continue: By 2045, the number of will increase by 1.5 times to 6 billion, adding 2 billion more urban residents. Cities are also important engines, with more than 80 percent of global GDP generated in cities

However, the speed and scale of urbanization brings challenges, including meeting accelerated demand for affordable housing, well-connected transport systems and other infrastructure, basic services as well as jobs, particularly for the nearly 1 billion urban poor who live in informal settlements to be near opportunities.

Cities also play an important role in tackling climate change, as they consume close to two-thirds of the world’s energy and account for more than 70 percent of global greenhouse gas emissions. As cities develop, their exposure to climate and disaster risk also increases. Almost half a billion urban residents live in coastal areas, increasing their vulnerability to storm surges and sea level rise.

Building cities that “work” – inclusive, safe, resilient, and sustainable – requires intensive policy coordination and investment choices. Once a city is built, its physical form and land use patterns can be locked in for generations, leading to unsustainable sprawl. National and local governments have an important role to play to take action now, to shape the future of their development, to create opportunities for all.
