Climate change causes global effects on multiple levels. The anthropogenic input of greenhouse gases increases the atmospheric mean temperature. It furthermore leads to a higher probability of extreme weather events (e.g., heat waves, floods) and thus strongly impacts the habitats of humans, animals, and plants. Against this background, research and innovation activities are increasingly focusing on potential health-related aspects and feasible adaptation and mitigation strategies. Progressing urbanization and demographic change paired with the climate change-induced heat island effect exposes humans living in urban habitats to increasing health risks. By employing scientometric methods, this scoping study provides a systematic bird’s eye view on the epistemic landscapes of climate change, its health-related effects, and possible technological and nature-based interventions and strategies in order to make urban areas climate proof. Based on a literature corpus consisting of 2614 research articles collected in SCOPUS, we applied network-based analysis and visualization techniques to map the different scientific communities, discourses and their interrelations. From a public health perspective, the results demonstrate the range of either direct or indirect health effects of climate change. Furthermore, the results indicate that a public health-related scientific discourse is converging with an urban planning and building science driven discourse oriented towards urban blue and green infrastructure. We conclude that this development might mirror the socio-political demand to tackle emerging climate change-induced challenges by transgressing disciplinary boundaries.

Against the backdrop of multiple ongoing crises in European cities related to socio-spatial injustice, inequality and exclusion, we argue for a smart right to the city. There is an urgent need for a thorough account of the entrepreneurial mode of technocapitalist smart urbanism. While much of both affirmative and critical research on Smart City developments equate or even reduce smartness to digital infrastructures, we put actual smartness—in the sense of social justice and sustainability—at centre stage. This paper builds on a fundamental structural critique of (1) the entrepreneurial city (Harvey) and (2) the capitalist city (Lefebvre). Drawing upon Lefebvre’s right to the city as a normative framework, we use Smart City developments in the city of Graz as an illustration of our argument. Considering strategies of waste and mobility management, we reflect on how they operate as spatial and technical fixes—fixing the limits of capitalism’s growth. By serving specific corporate interests, these technocapitalist strategies yet fail to address the underlying structural causes of pressing urban problems and increasing inequalities. With Lefebvre’s ongoing relevant argument for the importance of use value of urban infrastructures as well as his claim that appropriation and participation are essential, we discuss common rights to the city: His framework allows us to envision sustainable and just—actually smart—alternatives: alternatives to technocapitalist entrepreneurial urbanisation. In this respect, a smart right to the city is oriented towards the everyday needs of all inhabitants.
