More than half of the human population live in cities. It is projected that by the year 2050, two-thirds of all humanity — approximately 6.5 billion people — will reside in urban areas. Sustainable development cannot be achieved without significantly changing the way we build and manage our urban spaces.
This era of urbanization has emerged as a result of global population growth, increased migration and a boom in the development of mega-cities. Such factors are most evidenced in the developing world, wherein slums have become a common feature of urban life.
Developing sustainable cities will require both social and infrastructural innovation. This will mean providing safe and affordable housing, creating new livelihood and business opportunities, and building societies and economies to be more resilient. This transition will require further investment in public transport, the creation of green public spaces, sustainable urban planning initiatives as well as managing public spaces in an inclusive and participatory way.
