Risk assessment of major hazards and its application in urban planning: a case study

With the rapid development of industry in China, the number of establishments that are proposed or under construction is increasing year by year, and many are industries that handle flammable, explosive, toxic, harmful, and dangerous substances. Accidents such as fire, explosion, and toxic diffusion inevitably happen. Accidents resulting from these major hazards in cities cause a large number of casualties and property losses. It is increasingly important to analyze the risk of major hazards in cities realistically and to suitably plan and utilize the surrounding land based on the risk analysis results, thereby reducing the hazards. A theoretical system for risk assessment of major hazards in cities is proposed in this article, and the major hazard risk for the entire city is analyzed quantitatively. Risks of various major accidents are considered together, superposition effect is analyzed, individual risk contours of the entire city are drawn out, and the level of risk in the city is assessed using "as low as reasonably practicable" guidelines. After the entire city's individual risk distribution is obtained, risk zones are divided according to corresponding individual risk value of HSE, and land-use planning suggestions are proposed. Finally, a city in China is used as an example to illustrate the risk assessment process of the city's major hazard and its application in urban land-use planning. The proposed method has a certain theoretical and practical significance in establishing and improving risk analysis of major hazard and urban land-use planning. On the one hand, major urban public risk is avoided; further, the land is utilized in the best possible way in order to obtain the maximum benefit from its use.     

Town planning in Sweden: National officials versus local politicians

With strong central government traditions, Sweden has developed goal-oriented normative planning. At urban level, such planning raises many problems. This article discusses some of these problems from the three principal aspects of planning, namely the ideological, methodological and organizational aspect. The study is based on an extensive questionnaire and oral interviews among municipal planners in leadership positions in three middle-sized municipalities, namely Borås, Umeå and Västerås. The ideological aspect is discussed with reference to restrictions on urban planning arising as a result of decisions made by private enterprises and due to the interaction between the central and municipal government. The article goes on to describe the methods planners have developed to plan for land-use, resource allocation, housing and other sectoral activities and major defects in the planning system. Finally, the article discusses various problems faced by the municipal government whose departmental organization facilitates the administration of community services but cannot adequately deal with the increasing number of planning functions which are often interdepartmental in nature.     

Educational Landscapes and Urban Development. Contextual and Spatial Interfaces and Linkages

In the broad sociopolitical discussion on education quality within the last decade, it has become apparent that education is gaining importance for urban development, as well as space and the urban context are important dimensions of education. This becomes particularly evident in concepts for local educational landscapes (Ger. Bildungslandschaften). The young field of research on educational landscapes is currently lacking empirical research from spatial and planning sciences. In the paper, the current state of scientific research on educational landscapes in Germany and Europe and first insights to contextual and spatial interfaces and linkages between education and urban development in general are presented.     

Planning Interventions: Urban Bias,Social Reform and the City

The planning profession struggled for urban amelioration, but avoided confronting the conflict between the redistributive public interest and the goals of industrial capital, resulting in a devaluing of social planning in the US. This article classifies social biases in planning and relates them to sanctuary cities. In the current crisis, launched by the federal government’s hostile rhetoric to immigrants, the planning apparatus is forced to confront what it has sought to avoid – planning for the just, inclusive city that has to reckon with the presence of some of the poorest urban populations.     

Planning reform beyond planning: the debate on an integrated Environment and Planning Act in the Netherlands

Land-use plans serve a dual function. On the one hand, they are programmes for future development, plans for action. On the other hand, they have a regulative function in relation to construction and land use. This paper investigates how the interplay between these functions is playing a role in the current debate about the new integrated Environment and Planning Act (Omgevingswet) in the Netherlands. Initially, the government proposed abolishing local land-use plans and replacing them with a system of by-laws. However, this proposal did not survive the debate on this bill. This paper will shed light on the relationships between planning and regulation by analysing that debate.     

Spatial Planning in Ghana: Exploring the Contradictions

The purpose of this research is twofold: to explore the complexity of spatial plan preparation and implementation in Ghana using Kumasi as a case study; and second, to examine the contradictions of spatial plans and ‘actual development’ occurring in Kumasi. Using social science research methods (semi-structured interviews) and physical survey (land use plans), findings indicate that spatial planning in Kumasi is a bureaucratic process hijacked by urban planning agencies with limited involvement of urban residents. As a result, urban development is considerably influenced by spontaneous informal development patterns (i.e. self-organization). This phenomenon of self-organization is expressed in a context of uncertainty created by weak spatial planning system which encourages haphazard development. Regrettably, in Kumasi, self-organization is often overlooked by spatial planning agencies as they focused on rigid and exclusionary spatial plans. This paper advocates consideration and integration of self-organization processes in spatial planning efforts to respond adequately to the urban development challenges confronting Kumasi.     

Citizens' Anti-highway Revolt in Post-Pinochet Chile: Catalyzing Innovation in Transport Planning

During the last third of the 20th century, citizens throughout North America and Europe organized protests against urban highway projects, influencing urban transport planning in ways that shape its evolution to this day. With the globalization of car-centred urban planning models, some similar movements have emerged in developing countries. What, if anything, can they tell us about citizens' role in innovation to achieve more socially just, good and livable cities? Using a multidisciplinary approach grounded in planning theory and a local adaptation of participatory action research methods, this study explores lessons from an anti-highway movement in Santiago, Chile (1997). This study contributes citizens' perspective on crucial issues within the philosophy and history of city planning, examining shifts in governance that can significantly influence the potential for change in planning and city systems, even under adverse conditions. Is improving participation just a matter of ‘getting the process right’? This experience indicates that it requires re-formulating frameworks to encompass democratization, fostering multi-scalar, self-generating civil society organizations, and focusing on the role of organized citizens, rather than individuals, as they act on policy ecologies. The evidence from this Santiago case supports Portugali's argument that planning is both a profession, exercised by especially trained ‘experts’, and a skill exercised by citizens working from their everyday expertise. This example explores the mechanisms through which, even in a relatively hostile environment, self-generated citizen organizations may play a significant role in contesting business-as-usual debates and achieving innovative policies favouring greater equality and sustainability.     

LP/HC and LULUs: The Political Uses of Risk Analysis in Land-Use Planning1

This paper examines how LP/HC (low-probability/high-consequence) risk analysis is used in planning for locally unwanted land uses, or LULUs. LULUs are development projects that are predictably objectionable to many of their neighbors. Examples are nuclear power plants, hazardous waste facilities, refineries, and airports. The paper begins by elaborating the idea of LULUs, focussing on those whose planning typically requires or invokes some form of LP/HC risk analysis. It then discusses how land planning and planners actually use the LP/HC approach to deal with LULUs. It argues that in practice land-use planners and their associates employ a concept of risk different from that of economists, scientists, and engineers and more like that of political decision-makers and the public at large. It concludes with a political interpretation that offers some suggestions for productively reducing this divergence in the treatment of LULUs that pose LP/HC risks.     

Establishing Design Principles for Wildfire Resilient Urban Planning

This study elaborates on the built and natural environment disciplines’ potential to develop applied understandings of resilience, using the example of land-use planning design guides in wildfire-prone areas. It argues that land-use planning can develop and apply spatial and physical resilience principles to disasters, contributing to developing meaningful ways of achieving resilience by bridging the space between overarching goals and the specificity of individual contexts, focusing on physical resistance. It concludes that there are nine design principles that can improve settlements resilience in wildfire-prone areas to reduce risks, organized under two major categories: acting on resistance and facilitating response.     

Planners' Perspectives on Obstacles to Sustainable Urban Development: Implications for Transformative Planning Strategies

A major problem confronting planning is the gap between transformative proposals and enduring urban development trends. The paper interprets interviews with 62 planners involved in a sustainable urban development strategy in a large region focussed on Toronto, Canada. Surveyed planners were asked about the obstacles they encounter when attempting to modify prevailing urban development. Mentioned obstacles are consistent with expectations arising from three major perspectives on inertia: institutionalism, political economy and path dependence. Interviews also highlight the role of planners' practical knowledge in identifying and interpreting obstacles, and the existence of a consensus among respondents over sustainable urban development.     

Land-use planning in a world of shrinking resources

The paper contrasts two opposed strategies of land-use planning: the classical planning strategy of containment and conservation, and the strategy for outward displacement of land uses, here designated ‘Lemmings Rule’. It is shown how Lemmings Rule which has characterized recent years in Britain, despite the existence of the planning machine, has resulted in large-scale waste of the land resource through various landuse zones outward from the inner city. Statistics derived from the Second Land Utilisation Survey of the 1960s and sample resurveys of the 1970s are cited in support of the argument for a return to the insurance principle in planning.     

Planning without vision— Roots of the urban disaster

Urban planning, especially in the United States, arose in reaction to the forces of industrialization. Yet urban development remained subordinate to the deeper powers of the rising technological order and failed to find an independent inspiration, ideal, or initiative by which cities could integrate the bewildering social changes. A kind of self-defeat is proclaimed in the very language of planning. How did this happen? Even to begin to perceive the causes, it is necessary to search in the history, philosophy, and customs of the society within which urban planning emerged.     

New Spatial Concepts Between Innovation and Lock-in: The Case of the Dutch Deltametropolis

It is often proclaimed that planning concepts serve an innovative function in the political process. They are praised as powerful tools that carry new insights and understandings into policy arenas. By examining the emergence and development of a new planning concept in the Dutch national spatial policy-making process, the deltametropolis concept, this paper questions this position. It argues that new spatial concepts tend to lose much of their innovative capacities when they enter the political arena and become encased in the traditional urban–rural planning discourse, thus reaffirming established planning orientations. The Dutch case of the deltametropolis illustrates that new spatial concepts may entail potential for innovation as much as for lock-in.     

Fear and Urban Planning in Ordinary Cities: From Theory to Practice

The paper complements Abu-Orf's theory about violent settings by setting out a theory of fear in urban planning in ordinary urban contexts around three arguments: spatialization of fear; (modernist) spatialities and the encounter and political economies of urban fear. The three theoretical arguments are used to re-frame the planning history of Chelas, an affordable housing district in Lisbon, Portugal, and debate the way fear shapes, and is shaped in turn by, planning practice. Confirming that (growing) fear in ordinary urban contexts is not just an effect of the contemporary organization of cities, the paper argues for a theorization of fear that combines global (hegemonic) and a local (discursive/contingent) perspectives in the theorization of urban fear, and advocates for the need to put fear, and its capacity to create a crisis in urban policy, at the heart of planners' agendas.     

Resilience and Climate Change Adaptation: The Importance of Framing

In the Australian policy context, there has recently been a discernible shift in the discourse used when considering responses to the impacts of current weather extremes and future climate change. Commonly used terminology, such as climate change impacts and vulnerability, is now being increasingly replaced by a preference for language with more positive connotations as represented by resilience and a focus on the ‘strengthening’ of local communities. However, although this contemporary shift in emphasis has largely political roots, the scientific conceptual underpinning for resilience, and its relationship with climate change action, remains contested. To contribute to this debate, the authors argue that how adaptation is framed—in this case by the notion of resilience—can have an important influence on agenda setting, on the subsequent adaptation pathways that are pursued and on eventual adaptation outcomes. Drawing from multi-disciplinary adaptation research carried out in three urban case studies in the State of Victoria, Australia (‘Framing multi-level and multi-actor adaptation responses in the Victorian context’, funded by the Victorian Centre for Climate Change Adaptation Research (2010–2012)), this article is structured according to three main discussion points. Firstly, the importance of being explicit when framing adaptation; secondly, this study reflects on how resilience is emerging as part of adaptation discourse and narratives in different scientific, research and policy-making communities; and finally, the authors reflect on the implications of resilience framing for evolving adaptation policy and practice.     

‘Test Driving’ a Financing Instrument for Climate Adaptation: Analyzing Institutional Dilemmas using Simulation Gaming

Urban physical public infrastructure is a frontline defense mechanism to manage and mitigate climate-related impacts. Market instruments are often cited as possible means to spread risk and reduce financial burdens on the public sector. The authors argue that existing research tends to focus on the technical issues of instruments and neglects considering institutional dynamics that may enable or constrain local market-based financing mechanisms. In this article, three core dilemmas (values uncertainty, planning horizon, and indirect benefits) are used to analyze the responses of practitioners to a possible financing instrument. The findings indicate that the practitioner’s responses to tax increment financing were largely shaped by the adaptation dilemmas and not the characteristics of the instrument per se. By mapping the dilemmas onto whether they would recommend it, participants imposed a financial barrier on climate adaptation investments. The authors conclude that a key imperative in the design of policy instruments is to pay attention to the congruency of informal institutions at the ‘street level’ in order to be in-step with the current sociopolitical conditions. The findings also point to four key attributes that a local market-based instrument would need to be aligned and responsive to the Dutch planning and development context.     

Empty Signifiers of Transformation in Participatory Planning and the Marginalization of Black People in South Africa

There is no doubt that participation as a development paradigm for the transformation of planning in South Africa took off in the early days of democracy with a revolutionary zeal. The mood of transforming planning practice from apartheid planning associated with top-down authoritarian modernist systems towards bottom-up post-apartheid democratic systems was marked by the emergence of a deluge of African metaphors such as indaba, lekgotla, simunye, tswele pele, etc. These metaphors immediately entered the scene of planning and policy documents, and this was seen largely as signifying the increased participation of black people marking moments of inclusion, transformation and empowerment. However, the legacy of apartheid planning still pervades through the work that planners do and its arresting impact remains unabated in South Africa. This paper explores the emergence of these African metaphors in participatory planning and their implications on the transformation of planning in South Africa. The paper advances the argument that African metaphors of participation have acted as empty signifiers of transformation for black people in the integrated development planning process. While the metaphors are used to construct politically sellable image for participatory processes, participation has gained ideological traction to support Eurocentric and globalist traditions of urban change. Participation reflects a new way of thinking about order, peace and development, and the African metaphors are not instrumental in changing the Eurocentric and global capitalist logic presiding over the constitution of law, theory and the technical instruments of planning.     

Reviewing Implications of Urban Growth Management and Spatial Governance in the Global South

ABSTRACT

Urban containment policies have been applied in the global north as a strategy towards creating compact urban development. In the south the urban growth management discourse have been part of planning practice for the past three decades. There are however several reasons, both structural and political that have contributed to its limited success. The purpose of the research is to review practices of growth management in the south in an attempt to find lessons from the implementation of different mechanisms. The study focuses on the challenges of growth management mechanisms and its associated spatial governance approaches.     

Corporate Planning and Control in German industry

This article records some important results of an extensive empirical investigation in GFR. In so doing the structure and the stage of development of Corporate Planning and Control Systems in 355 industrial companies were analyzed—in addition other systems were investigated. Within the context of the planning and Control Systems, the multi-echelon organization of the system, the time scale and the differentiation of the plans as regards content, co-ordinated planning between various management levels (multi-echelon co-ordination) as well as the harmonization, adaptation and formalization of the plans and the planning, were investigated. Furthermore the content of the planning— for example, objectives, programmes, resources, and budgets—, the various sectional plans of the company, the organizational units, information as well as the interrelationship between the different management levels as regards information and the instruments for planning and control, were surveyed. In relation to the other systems, the organization, information, and management development systems as well as the general management system were analyzed.Within the context of the empirical investigation the structure and developmental stage of Planning and Control Systems in 355 industrial companies in the GFR were analyzed. As the basis for the empirical study a technological concept for Planning and Control Systems was worked out, which is based on a comprehensive planning and control theory.     

What is a Healthy Sustainable Built Environment? Developing Evidence-Based Healthy Built Environment Indicators for Policy-Makers and Practitioners

Abstract

Healthy built environments place people and communities at the heart of urban planning, encouraging decision-making based on human health, well-being and environmental sustainability. This paper describes the development of a set of indicators to assist in this endeavour—by translating and linking the research evidence base with policy-makers and other practitioners. The paper describes how the indicators were chosen, contextualized and subsequently structured to maximize useability for urban planners and health professionals working together to improve community health and neighbourhood sustainability.
