The transformation of infrastructures affects global relations and the prospects for sustainable development. Current global events have underlined the importance of infrastructures for a functioning international system. Yet they are vulnerable and highly contested. The way infrastructures are produced, operated and used are significant for global relations – and vice versa. In this project, we take an interdisciplinary approach to assess the influence of infrastructures on global order and the sustainable development of societies. A particular emphasis in this endeavor is on the realization of the United Nations’ Sustainable Development Goals. The project establishes a research network on infrastructures in Tübingen and lays the groundwork for a Collaborative Research Centre (CRC).
