Planning Adaptation: Accommodating Complexity in the Built Environment

Obsolescence and vacancy are part of the traditional building life cycle, as tenants leave properties and move to new ones. Flux, a period of uncertainty before the establishment of new direction, can be considered part of building DNA. What is new, due to structural disruptions in the way we work, is the rate and regularity of flux, reflected in obsolescence, vacancy, and impermanent use. Covid-19 has instantly accelerated this disruption. Retail failure has increased with even more consumers moving online. While employees have been working from home, rendering the traditional office building in the central business district, at least temporarily, obsolete. This article reflects on the situation by reporting findings from an 18-month research project into the practice of planning adaptation in the English built environment. Original findings based on interviews with a national sample of local authority planners, combined with an institutional analysis of planning practice since the 1947 Town and Country Planning Act, suggest that the discipline of planning in England is struggling with the reality of flux. There is a demand for planning to act faster, due to the speed of change in the built environment, and liberal political concerns with planning regulation. This is reflected in relaxations to permitted development rules and building use categories. However, participants also indicate that there is a concurrent need for the planning system to operate in a more measured way, to plan the nuanced complexity of a built environment no longer striated by singular use categories at the local level. This notion of flux suggests a process of perpetual change, turbulence, and volatility. However, our findings suggest that within this process, there is a temporal dialectic between an accelerating rate of change in the built environment and a concomitant need to plan in a careful way to accommodate adaptation. We situate these findings in a novel reading of the complex adaptive systems literature, arguing that planning practice needs to embrace uncertainty, rather than eradicate it, in order to enable built environment adaptation. These findings are significant because they offer a framework for understanding how successful building adaptation can be enabled in England, moving beyond the negativity associated with the adaptation of buildings in recent years. This is achieved by recognizing the complex interactions involved in the adaptation process between respective stakeholders and offering an insight into how respective scales of planning governance can coexist successfully.

On planning, planning theories, and practices: A critical reflection

The futility of defining planning suggests that there is no planning as a recognizable practice. Sociology of knowledge definitions imply three kinds of planning practices: (1) Generic “planning”—what people do when they are planning; (2) Knowledge-centered “something” (e.g., spatial) planning; and (3) Real planning practiced in specific contexts, from metro-regional planning for Jakarta to transportation planning for the Trans-Europe Network, and enacted in general contexts, for example, informal- or Southern planning. Planning theories are linked to different practices: generic “planning” theories and “something” (e.g., regional, community, environmental, or Southern) planning theories. Selected topics illustrate the “planning” theory discourse and spatial planning theories are briefly reviewed. Three generations of planning practice studies are reviewed: the first, a-theoretical; the second, the “practice movement,” who studied practice for their own theorizing; and the third, informed by practice theories. Five books about planning show how their planning theorist authors understand planning practice. While recognizing planning as diverse practices, they hardly apply “planning” theory to planning practices. “Planning” theories are divorced from enacted planning practices, “something” (e.g., spatial) planning theories include constructive adaptations of “planning” theories and paradigms, but knowledge about real planning practices is limited. Implications from these conclusions are drawn for planning theory, education, and practices.

SELECTED ASPECTS OF TALL BUILDING VISUAL PERCEPCION – EXAMPLE OF EUROPEAN CITIES

The article provides a preliminary analysis of selected factors that influence city visual perception, in particular tall buildings, in the cityscape. The research area includes selected European cities of a diverse urban structures and cityscape types. The cities also represent various strategies for the development of tall buildings. The article discusses tall building observation parameters, perception conditions and urban composition and geometry. It also describes techniques of digital cityscape analysis used by the author in her planning practice.

Planning in Times of Uncertainty

Coastal city-regions are dealing with new wicked problems due to climate change. Therefore, there is a demand for alternative paradigms and methodologies beyond the neoconservative perspective, demanding a transformative planning practice based on a territory-landscape plan as a catalyst for change. Landscape approaches are not ‘new,’ but they have become a driving paradigm in the international realm during the last decades. This paper explores the differences in taking a landscape approach on the Global North and South and discusses how a landscape approach can add value to coastal planning theory, especially when looking for the territories of the 21st metropolis. Conclusions have shown that landscape approaches from both Global North and South can strongly lead to a transformative and adaptive response.

Multiplicity of encounters. Zur Begegnungskapazität des öffentlichen Raums am Beispiel der HafenCity Hamburg

The planning of urban districts involves ideas of how people in cities would like to and should best encounter each other. The term “encounter capacity”, which denotes social as well as material dimensions of enabling “social mix”, has emerged in the reflexive planning practice of Hamburg’s HafenCity to increase the realisation of encounters through planned public space. This article explores the conception and reality of encounter capacity. It is based on commissioned research in the districts of the urban development area which were completed in 2015. The term “multiplicity of encounters”, developed from ethnographic observation and borrowed from the work of Doreen Massey, refers to the multiplication of encounters within specific horizons of meaning: neighbourliness, eventfulness and trendiness. The high-priced housing and consumption possibilities, the image of an exclusive district and the group-specific rhythms of everyday life are selectively but never completely cancelled out by these factors.

Impact of AI-Based Tools and Urban Big Data Analytics on the Design and Planning of Cities

Wide access to large volumes of urban big data and artificial intelligence (AI)-based tools allow performing new analyses that were previously impossible due to the lack of data or their high aggregation. This paper aims to assess the possibilities of the use of urban big data analytics based on AI-related tools to support the design and planning of cities. To this end, the author introduces a conceptual framework to assess the influence of the emergence of these tools on the design and planning of the cities in the context of urban change. In this paper, the implications of the application of artificial-intelligence-based tools and geo-localised big data, both in solving specific research problems in the field of urban planning and design as well as on planning practice, are discussed. The paper is concluded with both cognitive conclusions and recommendations for planning practice. It is directed towards urban planners interested in the emerging urban big data analytics based on AI-related tools and towards urban theorists working on new methods of describing urban change.

Closing the Gap Between Urban Planning and Urban Ecology: A South African Perspective

Ecological considerations should be an integral part of the decision-making processes of urban planners. Specifically, ecological aspects used in urban ecology, such as green infrastructure and ecosystem services, are substantiated by literature as strategies for improving quality of life, human health, and well-being. Studies dealing with such concepts in the Global South recently gained interest; however, these lack empirical evidence on the integration thereof in mainstream South African urban planning practice. This article conducts a preliminary investigation into the knowledge of ecological aspects of a sample of South African urban planners and their willingness to implement ecological aspects in urban planning practice. The new environmental paradigm scale is employed to determine the environmental worldview (ecocentric or anthropocentric) among respondent and how this relates to their knowledge of ecological aspects. The initial research sample consisted of a total of 283 questionnaires distributed. Although findings of this article are based on a low response rate (15%) of 42 documented responses, it did not affect the validity of the data collected in this context. The initial findings indicated that the environmental worldview of the sample of planners is only one factor influencing their perspective on incorporating ecological considerations. Low to moderate knowledge and awareness regarding ecological aspects such as ecosystem services, green infrastructure, and multi-functionality are argued to be main factors preventing integration in urban planning practice. Findings emphasize the need for context-based implementation strategies and broad recommendations are made for the planning profession as a point of departure to introduce or ingrain ecological considerations.
