Item On the horns of a dilemma: experts as communicators for property‐level flood risk adaptation measures(2023-01-18) Davids, Peter R.; Priest, Sally; Hartmann, ThomasThis paper investigates the role of flood risk experts in supporting homeowners to implement property-level flood risk adaption (PLFRA). Homeowners can reduce their flood risks by implementing PLFRA. However, oftentimes they need advice on what sort of and how to implement PLFRA. This means that tailored experts advice is necessary to inform homeowners on such measures. But experience shows that mere information is often insufficient to motivate homeowners to realise measures. This contribution explores the reasons for the ineffectiveness of expert advice by investigating how expert advice responds to homeowners' rationalities. Based on a case study from Flanders, Belgium, this paper reveals how the relation between experts and homeowners differs related to different rationalities of homeowners. The paper uses Cultural Theory to discuss strategies on how experts, providing advice on property-level risk adaption, could move beyond engineering skills by also using risk communication skills in order to involve homeowners in flood risk governance.Item The FLOODLABEL as a social innovation in flood risk management to increase homeowners' resilience(2023-12-08) Meyer, Helene; Hartmann, ThomasIn flood risk management awareness has been growing that the responsibility for coping with a flood cannot be assumed by the government alone. Homeowners need to be actively involved in flood risk management by taking responsibility; for this, they need empowerment and support to take adequate precautions. If homeowners implement precautionary measures, they can mitigate damage caused by floods and thus increase their resilience. This requires an appropriate risk communication strategy with the population. The FLOODLABEL in Germany informs and prompts homeowners to take precautionary measures. The Flood Competence Center developed the FLOODLABEL. This study employs the analytical framework of social innovation as the FLOODLABEL has some characteristics of social innovation. This study first explores the FLOODLABEL, which constitutes social innovation in flood risk management, and therefore characterizes the five development phases and their successes and challenges as social innovation. Second, it tries to understand and reflect upon the current stage of the FLOODLABEL as a social innovation in Germany and seeks to learn from this tool about the potential drivers associated with the process of implementation. Third, there is potential to gather a better understanding of other social innovations in flood risk management.Item Bodenpolitik und gewollter Leerstand(2023) Maurer, Astrid; Davy, Benjamin; Othengrafen, FrankIn the public perception, volitional vacancy is not yet sufficiently understood as a land policy problem. In the high-price segment of private residential property, volitional vacancy is closely linked to questioning the outcome of people amassing apartments in prime locations without spending much time there. It is after all their own private decision how they invest their money and what they do with their private property. In order to broaden the spectrum of future and innovative development potentials, a continuous and in-depth examination of developments relevant to the land market is required. This is precisely where this exploratory work comes in, helping to better understand a phenomenon that has been little studied to date - volitional vacancy. Volitional vacancy can have advantages and disadvantages for both the beneficiaries and those affected. The root of the land policy problem is not the phenomenon itself, but rather the interaction between the various actors involved in land policy. One group of actors, the owners, have unique and previously overlooked characteristics that contribute to the problem. As property owners, they value their freedom and the ability to make decisions regarding their land, yet they also have a responsibility to consider the greater good of the community. If landowners of residential properties leave their property unused or underused, they contriubute to housing scarcity and potentially increase tension on the housing markets. Such volitional vacant properties can be observed on many scales, from within individual cities to regions of entire countries. The central research question of this paper is: Is ownership of unoccupied housing in prime locations worth protecting? In summary, the answer is that intentional vacancy is protected under real estate law, but whether intentional vacancy in the wake of large-scale speculative investment projects is worth protecting is more controversial.Item The design of tourist maps. Creating spaces for travellers(2019) Preuß, Nadine; Davy, Benjamin; Thinh, Nguyen XuanThe present thesis deals with tourist maps. Although tourist maps are used by many people, there is a lack of research in this topic. There are no greater studies about existing tourist maps and there is also not much literature which claims how to design such maps. Present studies about tourist maps are always done from cartography’s point of view. Studies dealing with tourist maps from tourism’s point of view are missing. Therefore, one main aim of this thesis is to evaluate the quality of existing tourist maps. For this evaluation, technical literature about cartography and also tourism will be analysed. With the help of technical literature, design norms for tourist maps can be determined. After that, the design norms from literature are compared to existing tourist maps. Thus, it can be seen which cartographic rules are used in practice and which not. It will also be make clear which rules are maybe obsolete and which ones need to be followed in any case to make maps understandable. The thesis also shows how tourist maps can support spatial planning or how they can be of use in cities and areas which are affected in a negative way by mass tourism. The final aim of this thesis is to give design recommendations for tourist maps. These recommendations can be used for further production of tourist maps.Item Land use and social rights(2018) Yang, Yitu; Davy, Banjamin; Li, YangningThis thesis studies the themes of land use and social rights with special reference to the urban village, which is a special phenomenon in city-expansion in contemporary China. By conducting an extensive review of literatures on urban villages and boundary studies, the author studies land use and social rights from the perspective of boundary. The author also emphasizes boundary-making as a social construction process, which involves different stakeholders in this “game”. Further, the author reviews many historical documents and archives pertinent to land use and social rights in China and carries out a fieldwork in Nanjiao Village as a case study. Through qualitative analysis, this study answers the following research questions: 1) how are the diverse land uses arranged by boundary-making in the urban village; 2) how do the stakeholders maintain the order of the status quo for land use and the attained social rights in the urban village. The research found that different stakeholders are involved in the boundary-making of land use, which arranges the inclusion in and exclusion from the access to land use and the attainment of social rights in the urban village. The research concludes that through boundary-making of stakeholders, land use and social rights are inter-related and accessible for residents in the urban village. This research hopes to turn the spotlight on individuals’ social rights, when planners and interested parties make a plan of land use.Item Verfügungsrechte und Raumnutzung(Universität Dortmund, 2004-12-20) Bracke, Dirk; Davy, Benjamin; Dieterich, Hartmut
