Exploring the Urban Form and Compactness: A Case Study of Multan, Pakistan

Sustainable development has become an immense challenge, one further complicated by rapid population growth in developing countries. Therefore, analyzing the existing compactness of urban areas is essential for guiding future urban development. Most of the previous research on urban compactness has been conducted in developed countries, whereas limited research has been conducted on urban compactness in developing countries. This study fills this research gap and contributes to the current body of knowledge by offering empirical evidence of compactness measurement based on the existing urban form using Multan city as its context. Multan is a metropolitan city in the growing phase, so measuring its compactness for the promotion of sustainable development is crucial. For this research study, various indicators are adopted from the literature, such as land cover changes, density, land use, road network, congestion index, walkability index, and shape performance index, in order to evaluate compactness. The above-mentioned indicators were analyzed using ArcMap and ERDAS IMAGINE software. This study concludes that Multan city presently lies between compactness and dispersion. To achieve full compactness, highly dense vertical development with a better public transport network should be encouraged. In addition, the prevailing building regulations should be revised to increase the floor area ratio, and incentives should be devised for developers to promote vertical infill development. Moreover, there is an emerging need to formulate and implement compact city policies. By retaining the compact character of Multan city, sustainable development will be promoted. Ultimately, this research study would be a valuable resource for urban planners, decision-makers, and relevant authorities in proposing future compactness policies for sustainable development. This research can be applied to other cities with similar demographic characteristics, population, area, geographical conditions, and structure to that of Multan.
