Zwischen Transformation und Globalisierung - Immobilienmarkt und Stadtentwicklung in Warschau
(2006)
Nach der politischen Wende Ende der 1980er/Anfang der 1990er Jahre entwickelte sich in Warschau innerhalb kurzer Zeit ein hoch dynamischer Immobilienmarkt kapitalistischer Prägung, dessen Mechanismen grundlegende Auswirkungen auf die Stadtentwicklung Warschaus haben. Im folgenden Aufsatz werden die wesentlichen Eigenschaften des Büro- und Wohnungsmarkts aufgezeigt. Es werden für jeden Sektor die Funktionsweise, die wesentlichen Akteure der Nachfrage- und Angebotsseite, die Rolle der Institutionen und die räumlichen Konsequenzen dargestellt.
Knapp 30.000 Windenergieanlagen zwischen Nordsee und Alpen lassen unübersehbar erkennen, dass sich unser Energiesystem in einer umfassenden Transformation befindet. Allenthalben erfährt diese Entwicklung eine breite und kontroverse Rezeption und auch in der Denkmalpflege werden Windenergieanlagen aufgrund ihrer mitunter erheblichen Auswirkungen auf die Landschaft noch überwiegend als Störung wahrgenommen. Diese Arbeit nimmt dagegen die historische Entwicklung in den Blick und plädiert dafür, Windenergieanlagen als bedeutendes Kulturerbe zu verstehen. Angesichts des Voranschreitens der Energiewende wird angenommen, dass gerade älteren Modellen als baulichen Zeugnissen umfangreicher energiepolitischer Veränderungen seit den 1970er Jahren eine hohe Bedeutung zugeschrieben werden kann. Daher besteht das Ziel darin, Windenergieanlagen herauszuarbeiten, welche als hervorragende Zeugnisse der Entwicklung der Windenergienutzung in Deutschland zu bewerten sind.
Zur Annäherung werden diese zunächst als Untersuchungsgegenstand typologisch abgegrenzt. Eine wesentliche Besonderheit von Windenergieanlagen besteht darin, dass sie im Verhältnis zur eigentlichen Flächenversiegelung durch ihre vertikale Struktur erhebliche visuelle Auswirkungen auf die Landschaft haben. Anschließend wird die Entwicklung der Windenergienutzung seit den 1970er Jahren genauer betrachtet, welche insgesamt nicht linear verlief und von vielen Konflikten gekennzeichnet ist. Diese muss im Kontext eines wachsenden Umweltbewusstseins verstanden werden, das umfangreiche energiepolitische Veränderungen zur Folge hatte. Auf dieser Grundlage werden schließlich in einer denkmalkundlichen Reihenuntersuchung Windenergieanlagen herausgearbeitet, welche in hervorragender Weise von der Entwicklung zeugen. Die Auswahl bleibt allerdings mit sechs Objekten im Verhältnis zum Gesamtbestand von knapp 30.000 Anlagen relativ beschränkt, weil das auf die Abgrenzung von Besonderheiten ausgelegte etablierte Denkmalverständnis bei einem zeitlich so dichten Bestand gleichartiger Bauwerke an eine Grenze kommt.
Abschließend werden mögliche Erhaltungsperspektiven sowie denkmaltheoretische und -praktische Schlussfolgerungen diskutiert. Dabei ist unbedingt ein Erhalt am Ursprungsstandort anzustreben, wobei im Einzelfall entschieden werden muss, ob Belange des Funktions- oder Substanzerhaltes höher zu gewichten sind. Die skizzierten Auswahlprobleme regen darüber hinaus zur Diskussion zusätzlicher denkbarer Bewertungskategorien an, wobei sich insbesondere die gesellschaftliche Wahrnehmung und ökologische Werte aufdrängen. Zudem kann für die stärkere Berücksichtigung von Funktionszusammenhängen bei der Betrachtung technischer Infrastruktur in der Denkmalpflege plädiert werden. Insgesamt führt die denkmalkundliche Auseinandersetzung mit Windenergieanlagen damit weit über die Herausarbeitung einzelner Objekte hinaus und macht eindrücklich auf aktuelle Herausforderungen der Denkmalpflege und darüber hinaus aufmerksam.
The evolution of urbanism under dictatorship forms the core of the current research. This thesis is part of a research network at Bauhaus-Universität Weimar, which studies the 20th century's urbanism under different dictatorships. The network has provided a cross-cultural and cross-border environment and has enabled the author to communicate with other like-minded researchers. The 2015 published book of this group 'Urbanism and Dictatorship: A European Perspective' strengthens the foundation of this research's theoretical and methodological framework.
This thesis investigates urban policies and plans leading to the advancement of urbanization and the transformation of urban space in Iran during the second Pahlavi (1941-1979) when the country faced a milestone in its history: Nationalization of the Iranian oil industry. By reflecting the influence of economic and socio‐political determinants of the time on urbanism and the urbanization process, this work intends to critically trace the effect of dictatorship on evolved urbanism before and after the oil nationalization in 1951.
The research on the second Pahlavi's urbanism has been limitedly addressed and has only recently expanded. Most of the conducted studies date back to less than a decade ago and could not incorporate all the episodes of the second Pahlavi urbanism. These works have often investigated urbanism and architecture by focusing merely on the physical features and urban products in different years regardless of the importance of urbanism as a tool in the service of hegemony. In other words, the majority of the available literature does not intend to address the socio-economic and political roots of urban transformations and by questioning 'what has been built?' investigates the individual urban projects and plans designed by individual designers without interlinking these projects to the state's urban planning program and tracing the beneficiaries of those projects or questioning 'built for whom?'
Moreover, some chapters of this modern urbanism have rarely been investigated. For instance, scant research has looked into the works of foreign designers and consultants involved in the projects such as Peter Georg Ahrens or Constantinos A. Doxiadis. Similarly, the urbanism of the first decade of the second Pahlavi, including the government of Mossadegh, has mainly been overlooked.
Therefore, by critically analyzing the state's urban planning program and the process of urbanization in Iran during the second Pahlavi, this research aims to bridge the literature gap and to unravel the effect of the power structure on urban planning and products while seeking to find a pattern behind the regime's policies.
The main body of this work is concentrated on studying the history of urbanism in Iran, of which collecting data and descriptions played a crucial role. To prevent the limitations associated with singular methods, this research's methodology is based on methodological triangulation (Denzin, 2017). With the triangulation scheme, the data is gathered by combining different qualitative and quantitative methods such as the library, archival and media research, online resources, non-participatory observation, and photography. For the empirical part, the city of Tehran is selected as the case study. Moreover, individual non-structured interviews with the locals were conducted to gain more insights regarding urban projects.
Urban Heat Transition in Berlin: Corporate Strategies, Political Conflicts, and Just Solutions
(2023)
In the field of urban climate policy, heat production and demand are key sectors for achieving a sustainable city. Heat production has to shift from fossil to renewable energies, and the heat demand of most buildings has to be reduced significantly via building retrofits. However, analyses of heat transition still lack its contextualization within entangled urban politico-economic processes and materialities and require critical socio-theoretical examination. Asking about the embeddedness of heat transition within social relations and its implications for social justice issues, this article discusses the challenges and opportunities of heat transition, taking Berlin as an example. It uses an urban political ecology perspective to analyze the materialities of Berlin’s heating-housing nexus, its politico-economic context, implications for relations of inequality and power, and its contested strategies. The empirical analysis identifies major disputes about the future trajectory of heat production and about the distribution of retrofit costs. Using our conceptual approach, we discuss these empirical findings against the idea of a more just heat transition. For this purpose, we discuss three policy proposals regarding cost distribution, urban heat planning, and remunicipalization of heat utilities. We argue that this conceptual approach provides huge benefits for debates around heat transition and, more generally, energy justice and just transitions.
When working on urban planning projects there are usually multiple aspects to consider. Often these aspects are contradictory and it is not possible to choose one over the other; instead, they each need to be fulfilled as well as possible. In this situation ideal solutions are not always found because they are either not sought or the problems are regarded as being too complex for human capabilities.To improve this situation we propose complementing traditional design approaches with a design synthesis process based on evolutionary many-criteria optimization methods that can fulfill formalizable design requirements. In addition we show how self-organizing maps can be used to visualize many-dimensional solution spaces in an easily analyzable and comprehensible form.The system is presented using an urban planning scenario for the placement of building volumes.
Der Autor, Berater und Gutachter für das Thüringer Ministerium für Soziales und Gesundheit und Mitverfasser der Thüringer Landespflegepläne, systematisiert und analysiert die Struktur und Situation pflegebedürftiger Menschen und deren Inanspruchnahme sozialer Pflegeinfrastrukturen im räumlichen und demographischen Kontext. Im Mittelpunkt dieser regionalwissenschaftlichen Forschungsarbeit stehen räumliche Disparitäten der Versorgungs- und Angebotssicherung sowie bisher kaum betrachtete räumliche Strukturen und Interdependenzen der Pflegebedürftigkeit und Pflegeleistungen. Hierzu wurden vom Autor mehrere regional differenzierte Datenerhebungen aller teilstationären und vollstationären pflegebedürftigen Menschen und der Pflegeinfrastruktureinrichtungen im Freistaat Thüringen durchgeführt.Durch die Integration explorativer Analysemethoden in die empirische Regionalforschung wird die Pflegelandschaft Thüringens für den Zeitraum 1994 bis 2000 dokumentiert und anhand eines relationalen Indikatorensystems die Strukturen und räumlichen Muster der Pflegebedürftigkeit und -infrastruktur, soziodemographischen und raumstrukturellen Einflusskomponenten sowie pflegespezifische Interdependenzen exploriert und analysiert. Ein Ergebnis sind typologische Aussagen zum Alter, zur Pflegeart und -schwere oder Struktur der Pflegeleistungen in einer hochauflösenden topologischen Differenzierung nach regionaler Herkunft pflegebedürftiger Menschen. So hat die Einführung der Pflegeversicherung die Situation der meisten pflegebedürftigen Menschen in Thüringen deutlich verbessert. In der Zeitreihenuntersuchung treten diese Anfangserfolge aber hinter identifizierten Problemlagen aus z.B. sukzessiver Polarisierung der Pflegeleistungen, wachsenden Infrastrukturdisparitäten mit exakt quantifizierbaren Wanderungsbewegungen pflegebedürftiger Menschen zurück. Ein Ergebnis topologischer Analysen sind regionale (Versorgungs-) Disparitäten, die zu nachgewiesenen Wanderungsbewegungen pflegebedürftiger Menschen führen.So resultiert die noch nachweisbare Leistungs- bzw. Funktionsfähigkeit der Pflegelandschaft Thüringens (im Sinne der pflegerischen Grundversorgung einer Teilkaskoversicherung) primär aus noch günstigen Rahmenbedingungen wie dem „selbstverständlich“ erbrachten informellen Pflegeleistungen (der Frauen und Töchter) und nur sekundär (oder kaum) aus der durchaus noch guten finanziellen Situation der Pflegeversicherung. Ferner konnte gezeigt werden, dass wachsende Versorgungsdisparitäten nur anteilig eine Infrastrukturproblematik darstellen.Die Ergebnisse werden im Hinblick auf die entwickelten Methoden und weiteren Untersuchungen diskutiert und im Kontext des theoretischen Teils u.a. zur Entwicklung der Altenhilfe, Pflegeversicherung und sozialen Infrastrukturversorgung betrachtet und vor den Konsequenzen des demographischen Wandels reflektiert. Mit den Untersuchungsergebnissen fordert der Autor, dass Alterung und Schrumpfung der Bevölkerung in Teilräumen als dominante Entwicklung nicht verleugnet werden darf, damit durch eine integrative Gesamtsicht einer auch sozial nachhaltigen Raumentwicklung die pflegespezifische Forderung nach einem möglichst selbstbestimmten und selbständigen Leben (im eigenen Haushalt) gewahrt und das Grundrecht auf Würde auch pflegebedürftiger Menschen gewährleistet bleibt.Dazu wird vorgeschlagen, mit einer modernen Regionalforschung, die durch hochauflösende Datenerfassung, neuen explorativen statistischen Analysemethoden und in Verbindung mit aussagekräftigen Visualisierungsverfahren ein qualifiziertes Monitoring- und Analysesystem für die Raumbeobachtung aufzubauen, um Problemregionen rechzeitig identifizieren und Planungen zeitnah initiieren zu können.
This dissertation attempts to describe, analyze and evaluate how the settlement spaces of Chinese clans in rural areas were shaped by local clan lives in ancient times and transformed along with the transition of those clan organizations in modern China. In approaching this subject, two major questions are raised: what was the role of ancient Chinese rural clans in the spatial formation of their settlements and, nowadays, do they still play the same role as before?
To approach these answers, this dissertation sets out to draw on systematically interdisciplinary research from the perspectives of socio-culture and architecture- planning to have an overall understanding of a Chinese clan organization and clan settlement. Then, the basic characteristics of traditional Chinese clans and their importance to the Chinese people are discussed by tracing the history and evolution of Chinese clan organizations in the dissertation.
Two old villages, Furong and Cangpo in now Wenzhou, Zhejiang Province, are selected for case study research. And the research reveals that it was the clans that took charge of planning and managing the various construction activities, especially those of communal buildings and facilities, within their own settlements, and the clan lives exerted a decisive impact on shaping the settlement spaces, branding the characteristics of the clan lives clearly and deeply on the spaces. Following that, in the dissertation is described the transformation process of traditional Chinese clans in modern and contemporary China. The clan lives in rural areas have been reshaped and this exerts a great impact on clan settlement spaces. It is shown in the case studies of Furong and Cangpo.
One of the main focuses of recent Chinese urban development is the creation and retrofitting of public spaces driven by the market force and demand. However, researches concerning human and cultural influences on shaping public spaces have been scanty. There still exist many undefined ambiguous planning aspects institutionally and legislatively. This is an explanatory research to address interactions, incorporations and interrelationship between the lived environment and its peoples. It is knowledge-seeking and normative. Theoretically, public space in a Chinese context is conceptualized; empirically, a selected case is inquired. The research has unfolded a comparatively complete understanding of China’s planning evolution and on-going practices. Data collection emphasizes the concept of ‘people’ and ‘space’. First-hand data is derived from the intensive fieldwork and observatory and participatory documentations. The ample detailed authentic empirical data empowers space syntax as a strong analysis tool in decoding how human’s activities influence the public space. Findings fall into two categories but interdependent. Firstly, it discloses the studied settlement as a generic, organic and incremental development model. Its growth and established environment is evolutionary and incremental, based on its intrinsic traditions, life values and available resources. As a self-sustaining settlement, it highlights certain vernacular traits of spatial development out of lifestyles and cultural practices. Its spatial articulation appears as a process parallel to socio-economic transitions. Secondly, crucial planning aspects are theoretically summarized to address the existing gap between current planning methodology and practicalities. It pinpoints several most significant and particular issues, namely, disintegrated land use system and urban planning; missing of urban design in the planning system, loss of a human-responsive environment resulted from standardized planning and under-estimation of heritage in urban development. The research challenges present Chinese planning laws and regulations through urban public space study; and pinpoints to yield certain growth leverage for planning and development. Thus, planning is able to empower inhabitants to make decisions along the process of shaping and sustaining their space. Therefore, it discusses not only legislative issues, concerning land use planning, urban design and heritage conservation. It leads to a pivotal proposal, i.e., the integration of human and their social spaces in formulating a new spatial strategy. It expects to inform policymakers of underpinning social values and cultural practices in reconfiguring postmodern Chinese spatiality. It propounds that social context endemic to communities shall be integrated as a crucial tool in spatial strategy design, hence to strengthen spatial attributes and improve life quality.
Post Conflict Reconstruction is a very complex topic, whether it is to be undertaken by the Local or the International Community. The process of the Post Conflict Development is to be very hard to investigate, primarily for the combination of socio-cultural phenomena, war and political instability; having difficulties of conducting solid empirical analysis (obtaining reliable data) and dealing with war-torn communities. The multifaceted process of the reconstruction is ought to touch a lot of countries vital segments, whereas each of them requires different approach; coordination with one another; and unification in their common aim.
The emergency of the assistance programs are not equal, same as with the priority and weight when compared with each other, therefore occasionally there are programs for the success of which the other less important actions are violated or neglected.
The case is with the International Community presence ( the set up), which aside from their mission and projects, it is considered to play a very important role on the urban development of a post conflict city; the setting was never planned or considered in a holistic manner, therefore IC establishment was done ad hoc and it was guided by issues which did not help at its greatest to the urban development of the city and more over to the citizens who were most in need.
The study is about the Urban Development, due to the fact that the biggest concentration of the International Community is likely to be in the urban centers, and the experienced changes are of a much considerable magnitude. The reconstruction phase is likely to be lasting at about 10 years and more , consequently the International Community for that time being tends to be recognized as temporary citizens of the city, and it is inevitably that they will be having an impact on the urban development of the city; in that basis it is considered to be significant that the International Community Establishment/Set Up be included into the International Organizations mission and assist in the overall mission of the reconstruction.
The main hypothesis of this research is that civil society’s participation is able to improve the planning results in the Chinese city of Qingdao in the contemporary age. Qingdao is a young city developed from a German colony in eastern China. Apart from the powers of the government and the market, the 'third power', including mainly the power of volunteer citizens and the citizens’ organisations, also positively promoted the spatial development in Qingdao’s history. Since 1978’s reform, Qingdao’s great progress in urban housing, historic preservation, public space and urban traffic results mainly from the increasing strength of both the government and the market, while the government has always been the dominant promoter for urban construction. The actual planning mechanism – the government formulates 'what to do' itself and decides 'how to do it' with the market – has much limit in reacting to the rapidly changing situation, serving diversified social interests, and raising sufficient funds for the city’s urgent demands in Qingdao. Searching for new development strategies based on the understanding of civil society in the Chinese context can provide a promising perspective on the urban studies of Qingdao. Chinese civil society can be understood as the intermediate sphere of individuals, families, citizen’s organisations, social movements, public communication, and of the non-governmental body’s non-for-profit involvement for the provision of public services between the state and the market. China has its own cultural tradition of civil society, and the modern civil society in China is showing its great potential in improving social integration and urban life. The Chinese government has started to advocate for civil society’s participation in urban construction, and encouraging the 'bottom-up' mechanism in the planning-related issues through political statements and legislative approaches since the last two decades. The existing planning practice in China is able to demonstrate that civil society’s participation helps improve the quality of Chinese urban planning realistically under present conditions, and that moderation of planning experts and the push of the authority are the key factors for successfully integrating the strength of civil society in planning. However, the power of civil society is not yet sufficiently discovered in Qingdao’s planning. For better planning results, the city of Qingdao needs more initiatives to mobilize civil society in the planning practice, as well as more support to enrich the related studies. This thesis recommends that Qingdao establishes the 'Foundation for Collaborative Urban Solutions' through the joint efforts of the authority and civil initiatives, which aims at moderating and facilitating the strength of civil society. The suggested pilot projects include: a. The Community-based Housing Workshop for regenerating the living environment of the run-down communities, where the residents are willing to collaborate with the foundation with own efforts. b. The Heritage Preservation Workshop for suggesting an efficient supervision mechanism involving civil society which protects the historic heritage from being destroyed in the urban construction. c. The Public Space Forum for improving accessibility, quantity and ecologic function in the development of Qingdao’s urban public space with the knowledge and creativity of both the government and the citizens. d. The Mass Transport Forum for a realistic strategy for funding the rail-based traffic system in Qingdao through enabling the civil society - especially the individual citizens and their households to invest. The 'Foundation of Collaborative Urban Solutions' is able to improve Qingdao’s planning to cope with the urban problems the city are facing in its contemporary development, as well as to provide valuable reference for the further research of civil society’s participation in Chinese urban planning.
