The City

Due to irregular and uncontrolled expansion of cities in developing countries, currently operational landfill sites cannot be used in the long-term, as people will be living in proximity to these sites and be exposed to unhygienic circumstances. Hence, this study aims at proposing an integrated approach for determining suitable locations for landfills while considering their physical expansion. The proposed approach utilizes the fuzzy analytical hierarchy process (FAHP) to weigh the sets of identified landfill location criteria. Furthermore, the weighted linear combination (WLC) approach was applied for the elicitation of the proper primary locations. Finally, the support vector machine (SVM) and cellular automation-based Markov chain method were used to predict urban growth. To demonstrate the applicability of the developed approach, it was applied to a case study, namely the city of Mashhad in Iran, where suitable sites for landfills were identified considering the urban growth in different geographical directions for this city by 2048. The proposed approach could be of use for policymakers, urban planners, and other decision-makers to minimize uncertainty arising from long-term resource allocation.

Short Term Effects

It is a comparatively recent development that places housing not only as one of the main targets in the national plan, but also as a vital means of achieving other social and economic objectives.1 Admirable though this may be, a number of difficulties can arise in practice, particularly with regard to the question of new housing where many dwellings may be on unsuitable sites and require relocation or extensive redevelopment. The point is that remedial measures are likely to have only short-term effects, unless several underlying – and often conflicting – variables are taken into account. Four such variables have assumed importance in the planning for future housing needs in the Greater Manzini Area of Swaziland, and it is the purpose of this article to illustrate how policies relating to industrial location, urban growth, and housing, interact with the tenurial system in force.

This paper in its first part aims at contextualizing Abu Dhabi's urban development and understanding the factors that have governed its urban growth through a historical case study approach. Relying on archival records and primary sources five stages of urban growth are identified. Data mining of media archives allows for a first hand account of developments taking place thus grounding the depictions. The second part contextualizes this review through a case study of the Central Market project — also known as Abu Dhabi's World Trade Center. The paper concludes by elaborating on the significance of such a historical analysis as it shifts the discourse away from a focus on the ‘artificiality’ of cities in the Gulf to one that is based on a recognition about the historicity of its urban centers, however recent it may be. Additionally the pertinence of such an analysis for cities worldwide is discussed as well.

Cities have been the focus of recent sustainability and climate change mitigation efforts primarily because of unprecedented urban growth and ever-increasing resources consumption. A worrying trend has been the ever-decreasing life of buildings in cities because of premature building obsolescence. Premature building obsolescence has been cited as the major driver of demolition waste which accounts for more than 40% of total waste generated annually. This waste stream poses a bigger challenge as the pressure on natural resources increases with urban growth. A traditional way of looking at the urban sustainability has been from the perspective of the environmental sciences and waste management methods. Analyzing urban areas with design science perspectives could provide novel insights to improve existing resource consumption patterns and transform sustainability growth in cities. This study focuses on the problem of demolition waste arising from the premature building obsolescence in cities. It applies a design research methodology framework for identifying existing problems associated with demolition waste and generating strategies to transform cities into more sustainable urban systems. In the problem clarification phase, a detailed literature review was supported with stakeholder’s interviews to identify the state-of-art for building demolition process and demolition waste. Research was further extended to descriptive study-I phase to carry out a demolition case study and generate support tools to enable transformation in the existing scenario for achieving a desired state. Singapore, a dense city state of South-East Asia has been taken as a case study in this research. Results show that applying design research methods could help open-up a new dimension to solve urban sustainability challenge for built environment. It highlights that material reuse could lead to significant improvement in the built environment sustainability but the challenge associated with realization of material reuse practice needs to be addressed. Descriptive study-I concludes with the strategies on creating a reuse market through entrepreneurial innovation and an alternative material supply chain of secondary materials for regional housing demand. These results highlight the role of design research methods for tackling complex systems level problems in cities.
