For centuries, people have moved to and lived in cities. These urban centres are places to find work, friends and fun. It's no surprise that they continue to grow as more and more people flood in hoping to make the most of the chances they offer but adding to the congestion and pollution that already exist.

According to a report by the United Nations, 54 percent of the world's population lives in urban areas and it predicts that by 2050,this figure will have increased to around 70 percent. But as more and more people move from the countryside to the city to get better chances, they can end up with nowhere to live.

This is true in places such as Rio de Janeiro, where the people from the countryside can't rent or buy a home,and they end up building their own communities and houses on unoccupied land. These are called shanty towns— poor communities where the houses are built out of cheap materials—and often don't have any electricity or water supply.

These are, of course, not the future cities we want to see. Some serious urban planning is needed to make our cities of the future good, safe and modern places to live in. This involves improving the housing conditions, the chances for education and employment and so on.

Something urban planners are looking at now is the creation of“smart cities”. According to John Rossant, founder and chairman of the non-profit organisation New Cities Foundation, technology is the way forward. He thinks that it's generally accepted that “cloud computing, ubiquitous Internet, robust 5G networks etc, will change our cities”. He says technology is really “a game changer” in urbanization (城市化). It would collect large amounts of data about how a city is working and may improve how a city functions.
