City Networks

City networks and projects ensure that Berlin has close ties to the metropolitan regions and cities of Europe and the rest of the world. These city networks give Berlin a platform for the constant exchange of ideas and experience and for project-related cooperation between cities and metropolitan regions. The focus here is on issues that pose special challenges for these regions and cities at the beginning of the 21st century: climate change, the economy, science, culture, urban development, and social integration.
