In this class, we will focus on ongoing transformation processes of the Ruhr Metropolis in the context of a sustainable spatial and urban development. In this sense, we shall inquire how this post-industrial area has embarked on a pathway towards a sustainable transformation and how the region is dealing with current social, economic and environmental challenges. Furthermore, we will examine different concepts of regional governance thus far implemented in the Ruhr Metropolis in order to identify the main opportunities and obstacles to future regional strategies of urban and spatial planning, particularly with regards to climate change adaptation. The class seeks to engage in an interdisciplinary and international dialogue on urban transformation and provides a project-oriented approach to spatial development on the basis of several field excursions directly linked to the Emscher conversion and to the climate change adaptation programme “Zukunftsinitiative Klima.Werk” (Emschergenossenschaft).
