Goal 11: Sustainable cities and communities
More than half of the world’s population now live in urban areas. By 2050, that figure will have risen to 6.5 billion people – two-thirds of all humanity. Sustainable development cannot be achieved without significantly transforming the way we build and manage our urban spaces.
The rapid growth of cities in the developing world, coupled with increasing rural to urban migration, has led to a boom in mega-cities. In 1990, there were ten mega-cities with 10 million inhabitants or more. In 2014, there are 28 mega-cities, home to a total 453 million people.
Extreme poverty is often concentrated in urban spaces, and national and city governments struggle to accommodate the rising population in these areas. Making cities safe and sustainable means ensuring access to safe and affordable housing, and upgrading slum settlements. It also involves investment in public transport, creating green public spaces, and improving urban planning and management in a way that is both participatory and inclusive.
3.5 billion people, half of the world’s population, live in cities. By 2050, the urban population is expected to reach 6.5 billion
Cities occupy just 3 percent of the Earth’s land but account for 60 to 80 percent of energy consumption and 75 percent of carbon emissions.
Currently 828 million people live in slums, and the number is rising.
In 1990, there were 10 cities with 10 million inhabitants or more; by 2014, the number of “mega-cities” had reached 28.
In the coming decades, 95 percent of urban expansion will take place in the developing world.
1.2 billion jobs depend on a healthy and stable environment.
