The modern global society is an urban society. With the constant increase in the world’s population, the quantity and size of the world’s urban areas is also increasing. More than half of the almost 7 billion people on earth currently live in towns and cities. By the year 2050, this proportion will have increased to 69%.
At the same time, cities are an economic driver. 80% of the world’s gross domestic product is currently created in cities. But the process of world urbanisation does not follow a uniform pattern of development, but instead occurs under widely varying conditions. While urban growth in the developed industrial nations goes hand in hand with the development and expansion of modern infrastructure, the material and technical structures in the urban agglomerations of less strongly developed regions of the world develop unsatisfactorily in light of the rapid population growth in those regions.
The organisation of sustainable supplies of water and power to those in urban areas, the development of the public space, social welfare, health, protection of the environment and climate and waste disposal: these are all genuine urban tasks for which city planners and architects all over the world must seek solutions. They give new societal developments a spatial form, whether it be in the design of a building in an expanding quarter or as a complex urban concept that offers lots and lots of people space for activity and communication.
