Open Access Hitzeanpassung von Stadtquartieren: Akteursperspektiven und Umsetzungsansätze

Durch die projizierte globale Erwärmung werden sich Hitzeextreme verschärfen. Vor allem in den Städten wird die Lebensqualität der Stadtbevölkerung unter sommerlichen Hitzewellen leiden. Im Projekt HeatResilientCity werden bewohnerorientierte Hitzeanpassungsmaßnahmen an Gebäuden und im städtischen Freiraum entwickelt und geprüft sowie Empfehlungen für die Umsetzung gegeben.

The HeatResilientCity project applied insights from natural sciences, engineering and the social sciences to develop heat adaptation measures, test their effectiveness and partially implement them in two structurally different real-world laboratories in Dresden-Gorbitz and Erfurt-Oststadt. The present article discusses interventions to plant street trees and to refurbish two different residential buildings. We describe and analyse aspects of the implementation process to identify key factors that enable or constrain adaptation action among different groups of actors. We find that adaptation measures that are objectively effective and supported by residents are most appropriate for implementation. Where residents evince scepticism about adaptation measures, information about their effectiveness and usefulness should be disseminated. Early and targeted involvement of relevant stakeholders, careful communication and the establishment of climate adaptation as a permanent interdepartmental task at municipal level can promote successful implementation of heat adaptation measures.

Keywords: climate adaptation; implementation of adaptation measures; real-world laboratory; residents’ perspective; street trees; thermal adaptation of buildings; transdisciplinary research; urban districts

More about this publication?
  • GAIA is a peer-reviewed academic journal dedicated to inter- and transdisciplinary research on and for sustainability transformations.

    Environmental problems cannot be solved by one academic discipline. The complex natures of these problems require cooperation across disciplinary boundaries. Since 1991, GAIA has offered a well-balanced and practice-oriented forum for transdisciplinary research. GAIA offers first-hand information on state of the art environmental research and on current solutions to environmental problems. Well-known editors, advisors, and authors work to ensure the high quality of the contributions found in GAIA and a unique transdisciplinary dialogue – in a comprehensible style.

    GAIA is an ISI-journal, listed in the Science Citation Index Expanded, Social Science Citation Index and in Current Contents/Social and Behavioral Sciences.

    All contributions undergo a double-blind peer review.
