Since the beginning of the 21st Century the majority of the world population lives in an urban environment; every day there are thousands more people living in cities than the day before. The rate of urbanisation is increasing rapidly and the age structure of the urban population is shifting towards more elderly people. Environmental pressures are increasing especially in these urban areas. These developments challenge us to develop integrated sustainable solutions for economic, social and environmental problems. The future of humankind depends to a great extent on whether we will be able to boost the sustainable development of cities. Are you concerned?
