摘要

It is important to identify the suitable zone for urban built-up area development in highly populous countries in the global south. Therefore, this study was conducted in a medium class city in eastern India based on some significant influential factors and their sub-criteria. Different geophysical data, official data, and open street data were used to assess the land suitability for future urban growth by integrating MCDM techniques and different Geo-statistical models namely analytical hierarchy process, frequency ratio, weights of evidence, and evidential belief function. Based on the site suitability assessment outcomes, four different zones were identified such as very high suitability zone, high suitability zone, moderately suitable zone and low suitable zone. The findings of this study revealed that the central part of Midnapore municipality has been observed low suitability while more than 50% area is under moderate suitability zone. Moreover, the peripheral regions, especially in western, northern, and eastern parts are observed to be high to very high suitable zones for urban expansion. The outcome of the selected models has been validated (> 80%) by the receiver operating characteristics curve. Therefore, proper planning is required for western and eastern surroundings, as these areas are predominately forest cover and agricultural land respectively. Hopefully, the identification of proper site suitability will helpful for urban planner to reshaping the urban landscape as sustainable urban future.
