For a long prior time, planning is being deprived of resulting unplanned urban growth that happen consequences the urban problems. A GIS-based site suitability analysis using the AHP model is performed with criterion: land use, population distribution, water network, drainage network and road network. The suitable growth sites are determined through expert opinion, pair-wise comparison matrix and finally determining the weighted value. This paper found out the potential urban growth mainly in ward no. 2, 7, and 6. Optimally suitable places are those sites where future urban development can easily occur and have all the required facilities with available commercial, industrial, and official land use, moderate and highly suitable places need some facilities e.g., water supply, drainage management, road network and rearrangement of land use. Very few and partly suitable sites need major involvement of facilities and revisions of present land use for potential urban development. This information can be useful for policy makers for planning processes as an acceptable scientific process for site suitability analysis in the municipality area for avoiding the urban problems and ensuring sustainable development.
A GIS-based site suitability analysis using the AHP model is useful for policymakers to make proper planning.
Five criterions: land use, population, water-, drainage- and road network were used for the analysis.
Score values were assigned based on expert opinions and previous studies.
Urban land was classified into: Optimally suitable, mostly suitable, moderate suitable, partly suitable and very little suitable sites for potential urban growth in the Pabna municipality Area.
