Abstract
Many cities of various types are distributed in the large area of mountainous regions in China. In these cities, there are acute contradictions between man and earth. Considering that the space growth mode of mountainous cities is widely different from that of flatland cities, the fractal method was adopted in the research aimed at demarcating the urban growth boundary of mountainous cities. The fractal features of the investigated mountainous cities in space were figured out via inference from their function, dimension, region, grade, and environment, and the fractal mode and conceptual framework of urban growth boundary of Qin-Ba mountainous region were constructed according to some concepts and methods such as fractal dimension, fractal network, and fractal order. In the research, the traditional urban growth boundary form-was decomposed into scattered points (point form), paths (linear form), and patches (plane form) to form the fractal theory units for the research of urban growth boundary, and the leading idea, procedure, and control method for “fractal demarcation of urban growth boundary” were established to provide strategies for demarcation of urban space growth boundary of Qin-Ba mountainous region.

Abstract
Purpose
This study applies theoretical perspectives from urban, environmental, and organization studies to examine if “smart growth” represents an ecological restructuring of the political economy of conventional urban development, long theorized as a “growth machine” (Molotch, H. (1976) The city as growth machine: Toward a political economy of place. American Journal of Sociology, 82, 309–332; Logan & Molotch, 2007); the purpose is to determine if there is a “smart growth machine.”
Design
Nine smart growth projects (SGPs) in four cities in California and Oregon were identified and semistructured interviews were held with the respective developers, architects, and civic officials involved in their implementation process. Comparative, descriptive, and grounded approaches were used to generate themes from interviews and other data sources.
Findings
The findings suggest that an ecological modernization of urban political economy occurs through the coordination of entrepreneurial action, technical expertise, and “smart” regulation. Individual and institutional entrepreneurs shift the organizational field of urban development. Technical expertise is needed to make projects sustainable and financially feasible. Finally, a “smart” regulatory framework that balances regulations and incentives is needed to forge cooperative relationships between local governments and developers. This constellation of actors and institutions represents a smart growth machine.
Originality
The author questions whether urban growth can become “smart” using an original study of nine SGPs in four cities across California and Oregon.

Abstract
Over the last 30 years, despite immense and increasing expenditures by the federal government for disaster preparedness and relief, both catastrophic and chronic losses from natural hazards have continued to increase at an alarming pace. Although earthquakes, floods, tornadoes, and hurricanes account for the largest portion of these natural hazard losses, wildfire increasingly represents significant disaster losses of well over a billion dollars annually. There is considerable concern that losses from wildfires will only increase in the U.S. as some of the highest growth rates in the nation, both metropolitan and nonmetropolitan types of growth, are projected to continue in states with extensive wildland fire hazard areas. The land development patterns associated with that growth are problematic because so much of the development in the last 30 years (and that is still occurring) is not being steered away from the highest wildfire hazard settings, nor are adequate steps being taken to ensure that when development occurs in high wildfire hazard zones appropriate mitigation is used to reduce the vulnerability of people and property to loss. Fortunately, those anticipated future wildfire losses have a great potential to be reduced provided state and local governments take the initiative to create partnerships to ensure “safer” and “smarter” patterns of land development occur in and near wildland–urban interface areas. This chapter explores wildfire mitigation planning as an integral component of “safe smart growth” for wildland–urban interface communities.

Abstract
Purpose
Iran’s metropolitan areas are growing rapidly, and, among them, Shiraz has experienced a high rate of urban sprawl in recent decades. On the other hand, besides wasting the resources, urban sprawl does not follow the principles of sustainable urban development and its consideration would help to determine and employ the required type of sustainable urban development approach. The purpose of this paper is to assess urban sprawl in Shiraz.
Design/methodology/approach
First, the indicators and their weights for Shiraz’s sprawl assessment are identified through Delphi and analytical hierarchy process (AHP) methods. In addition, the degree of urban sprawl is assessed using the preference ranking organization method for enrichment evaluations (PROMETHEE).
Findings
The Delphi method produced the four criteria of “land use,” “urban fabric,” “social characteristics,” and “accessibility,” and “urban fabric” was the most important criterion per the AHP. Finally, the results of the PROMETHEE analysis indicated a high amount of urban sprawl in most of Shiraz’s municipal zones.
Practical implications
Therefore, due to the high degree of urban sprawl in Shiraz and its geographical limitations for horizontal development, a study on sustainable approaches to urban development in Shiraz, including Smart Growth and sustainable urban regeneration, seems mandatory for this city. However, this study indicates the requirement for more studies on urban sprawl in major cities of Iran, but by comparison of these findings with other relevant studies, it is inferred that using sustainable urban development approaches seems crucial for the majority of the cities in this country. Finally guidelines on how to impede urban sprawl and encourage sustainable urban development in Shiraz and Iranian cities as well as certain implications in this regard are discussed.
Originality/value
The findings of this study are expected to contribute valuable information for policy makers in terms of urban planning and the development of the cities in Iran.

Abstract
Purpose
Comprehensive urban management (CUM), with specified philosophical and technical limits, can address the negative consequences of the interrelationship between increasing urban poor population, spatial expansion of squalor and informal settlement on marginalised urban lands, overburdened and old urban infrastructure and increase in frequency and intensity of natural hazards. The research places these four concerns within the urbanisation context of the Kingston Metropolitan Region (KMR) in Jamaica, where their expressions are related to the lack of effective urban management and planning. The research uses a mixture of secondary information, from a myriad of public and private institutions and field surveys in the forms of observations and questionnaires. The cause and effects interrelationship between the factors are presented in a problem tree and analysed and discussed against known facts and theoretical posits. The paper aims to discuss these issues.
Design/methodology/approach
The research draws from a litany of document analysis, qualitative research as well as pre-coded questionnaires, field research and expert interviews and discussions with urban managers. Information and data selected from state and quasi-state agencies also proved valuable. Additionally, other relevant materials were sourced from the published domain including publications, journal articles, newspapers, textbooks and internet (online professional group discussions), etc.
Findings
Increase in urban poor over the last ten years increase in squalor settlements on marginal urban lands. Urban infrastructure is old and overburdened. Natural hazards are on the increase and are associated with negative demographic and social dynamics. Development plan and planning is lacking in the KMR. Urban management roles and responsibilities are not clearly defined. There are gaps and overlaps in roles and legislations. CUM needs redefinition for it to be effective in solving this relationship. Limits can be set for defining comprehensive urban planning.
Research limitations/implications
Space to explore more the relationship and evidences of the factor under investigation to their fullest extent.
Practical implications
Investments in urban infrastructure and other built environment and physical structures in important for urban resilience to hazards. Non-traditional countries and agencies are good source of financial and technical support for developing countries to improve their urban and national physical and social infrastructure. Urban land management and administration are crucial or urban spatial planning and land use.
Originality/value
The four factors under investigation, even though they are not novel in their individual treatment, are however original in the context of assessing their interrelationship and moreover their relationship with CUM. A redefinition of CUM is attempted to give stated criticisms of its past failures. The application to Jamaica and its potential application to other small island developing states are unique.

Abstract
Purpose
The purpose of this paper is to examine the regulatory, policy and market‐based approaches taken to incorporate biodiversity conservation in the management of urban growth in Sydney and more broadly in New South Wales, Australia's most populous state. Problems associated with managing Sydney's growth – particularly from the intersection of dealing with perceived property rights and the protection of natural resources such as biodiversity – are identified, and the scope for hybrid “smart regulation” is examined.
Design/methodology/approach
The relevant issues are illustrated through significant State Government development decisions relating to the retention of biodiversity in the new growth areas of Sydney.
Findings
The paper argues that to better integrate biodiversity conservation in Australian cities a mixed approach be adopted in which a number of tools are utilised – and that this needs to occur in the context of a sound overarching strategic planning framework. This constitutes a hybrid approach involving a “fixed” strategic spatial plan informing statutory‐based regulation primarily through zoning and other development controls, augmented by a range of market based tools implemented through statute and common law measures such as conservation covenants.
Originality/value
Singular reliance on traditional “command and control” regulatory approaches as both a cause and ineffectual solution to the problems faced in biodiversity conservation is highlighted. Newer “market based” mechanisms which are being introduced (e.g. biobanking), or should be adopted (e.g. transferable development rights), and management at the strategic level (e.g. biodiversity certification), are examined.
