    Abstract: Information about the spatial patterns of residents is essential, especially when elderly people are involved, as their action range is confined to their residential location. Since knowledge about patterns of elderly people in cities is limited, this paper formulates steps for the initialisation of an agent-based model, combined with different data sources. The first step is to identify different types of elderly people using cluster analysis, and then the clusters are expanded into agent typologies with behaviour rules, which form the basis for an artificial population. The clusters are derived based on survey data and then analysed and modified using insights from census data and expert interviews. The agents' relocation behaviour is estimated based on literature research, expert interviews and a survey. The spatial information of the agents is added with a spatial microsimulation. The resulting artificial population presents the real population well and can be used in an empirically based data-driven agent-based model.

    Abstract: Cities that begin to regrow after a long period of decline and land abandonment are under pressure to provide comfortable housing conditions in preferred neighborhoods for their residents. On the other hand, these cities should preserve interim green spaces that result from decline because these spaces are a real treasure for densifying cities. Using the case of the city of Halle in post-socialist Eastern Germany, we explore four land use alternatives for neighborhood development close to what might happen: (1) urban densification, (2) spacious housing, (3) the green city, and (4) the edible city. We seek to discover opportunities for regrowth and sustainable land use development by applying the ecosystem services and green points frameworks to a set of land use transition rules. Land use change has been defined for strategic development areas according to the Master Plan and complementary visions of land change. The results of the study provide highly interesting insights into how both regrowth and greening can be enabled in densifying neighborhoods and what types of green are most effective in providing carbon storage and summer heat regulation. Moreover, gardens, as central elements of the edible city concept, were found to be flexible in implementation in very differently dynamic neighborhoods by providing multi-functional spaces for ecosystem services such as climate regulation, local food production, daily recreation, and nature experience. Results demonstrate that ecosystem services benefit flows increase only in districts where real estate pressure is low. In districts with growing population numbers, green spaces are reduced. This may result in increased injustice in green space availability seeing as we have modeled a recreational space per capita of 〈 9 m² in the Southern Suburb, whereas an increase to almost 70 m² was simulated in the shrinking, prefabricated Newtown. Most importantly, modeling the narratives of the Master Plan in a spatially explicit way demonstrates unused potential for greening in Halle. Thus, we conclude that urban planning should make regular use of such land use alternative to look for hidden combined visions of green and growth in a formerly shrinking city.

    Abstract: Inter- and transdisciplinary research projects bring with them both challenges and opportunities for learning among all stakeholders involved. This is a particularly relevant aspect in social-ecological research projects, which deal with complex real-world systems and wicked problems involving various stakeholders’ interests, needs, and views, while demanding expertise from a wide range of disciplines. Despite its importance in such research efforts, the learning process is often not the primary focus of investigation and therefore the knowledge about it remains limited. Here, we put forward an analytical framework that was developed to assess the learning process of both the research team and other participating stakeholders within the scope of an international transdisciplinary project dealing with urban green and blue infrastructure. The framework is structured around five dimensions of the learning process: “Why learn?” (the purpose of knowledge generation and sharing); “What to learn about?” (the types of knowledge involved); “Who to learn with?” (the actors involved); “How to learn?” (the methods and tools used); 'When to learn?' (the timing of different stages). We developed an interview protocol to operationalize the framework and tested our approach through interviews with project researchers. Based on our empirical results, we draw main lessons learned that can inform other transdisciplinary projects. These include capitalizing on what already exists, addressing trade-offs inherent to different types of knowledge, fostering inter- and transdisciplinarity, engaging stakeholders, supporting a learning environment and fostering reflexivity. Besides the empirical insights and the lessons we present, the main contribution of this research lies in the analytical framework we developed, accompanied by a protocol to apply it in practice. The framework can capture the learning process taking place in transdisciplinary research more comprehensively than similar existing frameworks. The five intertwined dimensions it covers are essential to understand and plan such learning processes.

    Mapping mental barriers that prevent the use of neighborhood green spaces (2021)

    Abstract: In comparison to the study of green space use, the study of its non-use or rejection is greatly understudied. Neighborhood managers and members of local gardening initiatives of Halle-Newtown, Germany, state that residents ignore local green-blue infrastructure (GBI) for recreational use. Halle-Newtown is a former showcase, large prefabricated socialist housing estate that is now facing an increase of households deprived in multiple ways. We are interested in the question of why people of Halle-Newtown refuse to use local GBI. In order to uncover potential barriers to the enjoyment of the ecosystem service benefits of local GBI, we have chosen the method of mental mapping to explore place attachment in Halle-Newtown. In summer 2018, about 100 residents of Halle-Newtown described the places they prefer when relaxing from a stressful and hot summer day. The results were surprising. Local GBI, be it created in socialist times or recently, was completely absent from their mental maps. Instead, people would overcome longer distances and cover higher costs to reach central green spaces. Tacit knowledge, namely the untold general rejection of the entire neighborhood by the residents, was found to be the deeper reason behind non-use of GBI and missing place attachment. The results uncovered that both neighborhood neglect and the multi-scalar character of urban recreational ideas/behavior are factors that help us to understand non-use of urban GBI, two key insights for urban planning.

    Abstract: This paper offers an exploratory overview of different research literatures examining the relationship between urban nature or green space on the one hand, and marginalized, stigmatized, and illicit activities on the other. We situate this discussion within the geographic literature concerning assemblage theory and informality, and apply these concepts to urban green space. We offer some comparative examples from Detroit and Berlin, two cities known for their green space and illicit activity, but with very different histories and cultural contexts. For this purpose, we draw on our own primary research in both Detroit and Berlin, examining how the dynamics of these interactions produce diverse and distinctive urban places in some cases and associations of danger or insecurity in others, sometimes both simultaneously. We utilize diverse methodologies, including qualitative interviews and focus groups, mobile explorations, photography, and sketching to provide examples of spaces as complex assemblages of actors with diverse, emergent potentials. We conclude by contending that green spaces and urban nature belong on the same map as studies of informal and illicit activities, adopting a more fluid conception of the shifting relationship between people and green space in the evolving city.

    Abstract: Two of the dominant processes shaping today’s European cities are the ageing and diversification of the population. Given that the range of action usually decreases in later life, the living environment around the place of residence plays an important role in the social integration of the older generation. Hence, spatial patterns of residence indicate the extent of opportunities for the older population to engage in urban life and, therefore, need to be addressed by urban planning and policy. The aim of this article is to study the interrelation between diversity in later life—in terms of migrant history, gender, social class, and age—as well as planned and actual (past) movements of elders. We have chosen Berlin as a case study and draw from a quantitative survey with elders (age 60+) from diverse backgrounds (N = 427). Our results from descriptive analysis and statistical hypothesis tests show that age impacts people’s past and planned movement; we observe a peak in the decisions to move at the age of 65–75 and a drop in the inclination to move among people over 80. None of the other factors is similarly influential, but we observe appreciable tendencies regarding the impact of gender and social class on planned movements. Our study suggests that variables other than classic socio-demographic data, such as apartment size, rent, social networks, and health, and their interrelations may offer a promising starting point for achieving a full picture of older people’s movement behaviour.
