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.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
