Land suitability analysis for urban development in a secondary town in Bangladesh

Abstract

Sitc sclection for urban development requIres consideration of a comprehensive set of factors and balancing ofmulliple objecti\es m determining the suitability 01'a particular area for a defIned land use, The selection of an indllstrial site involves a complex array of critical factors drawing from economic, social, technical, and environmental disciplines. Spatial decision makmg problems, such as site selection for any particular use, require proper means to handle the multiple socio-economie factors while considering physical suitabihty com!Jtions. GIS that have been reeognired as useful decision support technology hut it does not provide means to deal with multiple decision factors, With these issues in mind, this study developed a Jramework for integrating the strengths of GIS and the AliP to incorporate the deeision-maker's preferences on a range of factors in fInding optimally suitable sites. This study illustrates how land suitability analysis can be applied to an urban development site selection problem. The aim of this research is to gain a better understanding of the concept of Land suitability analysis related to urban development in a secondary city of Bangladesh. This is IJIlderlaken by means of Analytical Hierarchy Process (AHP) methodology. This stndy provides a methodology tor site selection process in the presence of multiple and diverse dceision criteria using AHP, The nsc ofthc AHP in the fIeld of property development/estimating the value of a residential real cstatclhouse selection is very promising. In this study, Pabna municipality has been chosen for developing the concept of Land Suitability Analysis for Urban Development. The model kno,,", as ABP has been ulililed to developing the cone cpt of Land Suitability Analysis for Urban Developmcnt. Data was eollceted from Experts and field survey (Inter-Grid-ceJl Survey).
