In the past years, the transiency of European city-making and dwelling has become increasingly hard to disregard. This urban flux calls for a methodological rethinking for professionals, social and natural scientists, artists, and activists with an interest in the processes of remaking and reclaiming urban space. With a practical and empirical emphasis, this anthology brings forth a variety of perspectives on urban appropriation strategies, their relation to public space-making, and their implications for future city development, exploring how ideas and practices of appropriation inform and relate to cultural narratives, politico-historical occasions, and socioecological expressions.
