Third-party funded project

Urban Resilience vis-a-vis Extreme Weather Events - Typology and Transfer (Research and Development Phase) (ExTrass)

Research department: Politics and Planning

Project Leader within IRS: Prof. Dr. Kristine Kern

Project Team: Dr. Wolfgang Haupt Dr. Peter Mark Eckersley Dr. Stefan Niederhafner Janne Lis Irmisch

Consortium: University of Potsdam (Coordination) Leibniz Institute for Research on Society and Space Adelphi Research Potsdam Johanniter-Unfall-Hilfe e.V. Remscheid Würzburg

Funding Organization: Federal Ministry for Education and Science (BMBF)

Duration: 10/2018 - 12/2021


ExTrass seeks to better prepare medium-sized and large cities in Germany for heavy rainfall and heat. To this end, restraining and enabling factors of urban climate adaptation are analysed and successfull measures are identified. A large part of the project work is undertaken in three case study cities: Potsdam, Remscheid and Würzburg. Here, among other things, the project team tests greening measures, works towards climate-sensitive urban planning, contributes data on city climate, educates the population on risks and improves contingency plans. In addition, opportunities for exchange are created so that cities can better learn from each other.

Two New Articles Show, how Cities Become Forerunners of Climate Policy

Two new articles from the Research Group Urban Sustainability Transformations shed light on how cities are becoming pioneers in climate policy, both in climate protection and in climate adaptation. Instead of the metropolises often mentioned in this role, such as Paris, the authors take a look at smaller cities in Germany. In doing so, they show that even cities with difficult starting conditions can find their way into the top group. more info
