The ecological, economic, social and cultural challenges of our time all come together in the city. Integrated urban development mediates between different content-related, spatial and temporal levels of urban planning and urban politics. It takes a variety of topics into account - from climate change to the transport and energy transition, from digitisation to affordable housing to the “Economy 4.0”, from social cohesion in cities to democratic participation. Developing an integrated city means bringing these topics together across disciplines and balancing the various interests involved. Always with the aim of developing future-oriented solutions for the sustainable development of the European city.
