“…However, there is no one consensus or a universally accepted model with regards to the delineation of the UGB [55]. Sinclair-Smith [25] divides the process in which UGBs are delineated into three approaches. For the first approach, little or no quantitative assessment was performed for boundary delineation, and it was particularly prevalent in the initial adoption of UGB.…”

“…It further recommends the integration of 110 to 125 percent of projected urban growth as a long-term land use planning strategy. Sinclair-Smith [25] explains that the purpose of including additional land within the UGB, than what is required, is to prevent owners from monopolizing vacant land, thus allowing for effective and competitive real estate markets. As compared to the time-driven approach, where the expansion of an established UGB to accommodate future growth occurs at a set time interval, the inventory control system proposed by Knaap and Hopkins' [66] is an event-driven approach, where an increase in the developable land for the UGB is triggered only after the available land within the UGB is diminished to a predetermined level.…”

“…The adoption of UGB in developing countries and transitioning economies [20] has been limited. To the best of our knowledge, there have only been five developing or transitioning countries where UGB has been explicitly implemented as an urban growth control mechanism: namely Albania [21], Chile [22], China [23], Saudi Arabia [24], and South Africa [25]. Although the concept of UGB remains the same in both developed and developing countries, it should be noted that the planning and implementation of the UGB for developing countries will require distinctly different approaches as compared to developed countries, particularly due to differences in the nature of urban expansion observed in these countries [26].…”

With the rapid and unregulated nature of urban expansion occurring in Chattogram, Bangladesh, the adoption of urban growth restriction mechanisms such as the urban growth boundary (UGB) can provide a robust framework necessary to direct the development of built-up areas in a way that curtails the growth in environmentally sensitive areas of the city. Using a support vector machine (SVM)-based urban growth simulation model, this paper examines the areas of future contiguous expansion of the city to aid in the delineation of the UGB. Utilizing landcover, topographic, and population density data from a variety of sources for the past twenty years, the SVM method with the radial basis function (RBF) kernel is used to develop a model based on fourteen predictor variables. A grid-search is used to tune the hyperparameters and determine the best performance combination of the hyperparameters for the RBF kernel function used in the SVM. The final SVM model using the best performance combination of the hyperparameters indicates a high percentage agreement of 91.79% and a substantial agreement for the Kappa coefficient of 0.7699. The developed SVM simulation model identifies potential areas that are more likely to undergo urban expansion in Chattogram in the next twenty years and provides aids for a stringent and strict delineation of UGB for this region.

“…Initial post‐apartheid programmes such as the Reconstruction and Development Programme (South African Government of National Unity, ) which, in an attempt to assist the immediate housing shortage, favoured the establishment of single dwelling residential units for low income communities, on single plots on affordable land at the urban periphery (Horn, ) contributed to urban sprawl and even though national housing policy has since evolved on paper with the introduction of Breaking New Ground (South African Department of Human Settlements, ), the spatial outcomes of public housing development have remained unchanged, and is greatly exacerbated by the continuous accretion of informal dwellers of in‐migrants at the urban fringe. The research area for this paper is the Western Cape Province in South Africa, which in all aspects exhibit the spatial challenges described above (see Haferburg & Obenbrugge, ; Sinclair‐Smith, ; Turok & Watson, ). The province consists of one metropolitan municipality (The City of Cape Town), and five district municipalities, accounting for twenty four local municipalities in total.…”

This research proposes an urban sprawl index as a tool to comparatively analyse the extent of urban sprawl between cities and towns of different sizes, making use of cadastre, land use and population data over time. The Urban Sprawl Index (USI) for the Western Cape put forward by this research will enable the comparative measurement of the extent of urban sprawl proportionately between the Metropolitan and local municipalities in the province and thereby aid in understanding trends in formal and informal development processes, as well as the spatial planning instruments applied to guide development.

“…Urban sprawl is a visually perceivable landscape phenomenon and represents an important topic for analysis and assessment towards the sustainable development of urban areas [1][2][3][4]. In Burchell and Galley [5] (p. 151), sprawl is defined as " low-density, leapfrog development characterized by unlimited outward extension.…”

An Approach to Assess the Effectiveness of Smart Growth in Achieving Sustainable Development

Smart Growth has become an evident concept in public policy debates and provides answers to the enduring problems of sprawling development and its many adverse consequences. While the concept has widely been touted to promote an urban development pattern characterized by compact and mixed-use development, walkable and bikeable neighborhoods, preserved green spaces, and the availability of mass transit, not much has been written about its contribution to sustainable development. This paper is an attempt to explore the concepts of smart growth and sustainable development and the extent to which the former contributes to the achievement of the latter. The various debates surrounding the smart growth movement have also been explored. The 2003 general plan guideline by the US State of California is used as the basis for determining the sustainable development role of smart growth policies in Portland (Oregon), Arlington (Virginia), Boulder (Colorado) and Lancaster County (Pennsylvania). The paper concludes that it would be inappropriate to equate smart growth to sustainable development as the latter is a much broader concept and cuts across myriad disciplines. Notwithstanding, the implementation of smart growth policies in the cases studied have been observed to promote compact, infill and transit-oriented development and to conserve and protect open spaces and natural areas. All these are pro-sustainable development. While this paper has observed that smart growth serves as one of the approaches for achieving sustainable development goals, it calls for a more quantitative study to be able to measure the magnitude of the contribution associated with the smart growth policies.
