GIS-based multi-criteria analysis modeling used to locate suitable sites for industries in suburban areas in Bangladesh to ensure the sustainability of agricultural lands

Abstract

Land use changes significantly affect the sustainability of food security, environmental quality and the ecological balance in developing countries. Bangladesh is one such country, and it faces challenges caused by its limited resources of arable land. The urbanization of agricultural lands and urban developments in suburban areas add to these challenges. Therefore, the aim of this study is to characterize the land use changes that occur over time in suburban areas that have potential for industrial growth. This study also assesses potential locations for industrial development by using land suitability analysis (LSA) to emphasize both agricultural and industrial development in terms of sustainable growth. A geographical information system (GIS)-based multi-criteria analysis (MCA) model is developed for the LSA to distinguish compact parcels that are suitable for industrial economic zones. Nine criteria, including seven constraints and 23 factors, are evaluated using the spatial analysis tools in ArcGISÒ . An analytical hierarchy process (AHP) is applied to prioritize these criteria based on experts opinion for the decision-making process of LSA. This study finds that the construction of densely clustered industrial areas has decreased the area of agricultural land by more than 10% in the last two decades. Furthermore, the results of the LSA show that only 4% of the land was highly suitable for industrial sites. On the other hand, four compact parcels that contain 16-10 ha of land and suitable for small industrial zones exist within the study area. Thus, the integrated GIS-MCA model can serve as a policy and planning tool for locating industrial economic zones while preserving agricultural lands and retaining environmental protections.& Tofael Ahamed

Land Suitability Analysis for Identifying Industrial Zones in Duhok District, Kurdistan Region of Iraq

“…Seven constraints and 23 factors were evaluated. They stated that the integrated GIS-MCA can serve as a policy and planning tool for locating industrial zones while retaining environmental protection [27].…”

“…For identifying suitable industrial zones, effective factors should be identified first. In this study, the factors were selected from previous similar research [1,2,3,20,21,22,23,24,25,26,27], and national and international regulations. A comprehensive set of factors were identified and then the factors were carefully screened to select the final factors based on data availability.…”

“…LSA is a process of identifying an appropriate area for a specific land use (Muhsin et al . ). In other words, it is a tool for spatial decision‐making in which criteria are evaluated by planners to match requirements of land use.…”

“…Despite these hazards, Bangladesh has witnessed substantial improvement in agriculture over the past decades, although almost 24.2 million people remain in food-scarce situation (Hassan et al, 2019;Molla, 2019). Contrarily, rapid industrialization and urbanization provoke transforming of 69,000 hectares of agricultural lands to non-agricultural practices annually, and its rate is gradually increasing thereby threatening the upcoming cultivable land in the country (Khan, 2019;Muhsin et al, 2018;Rahman et al, 2016). Additionally, cereal crops including rice occupies more than 75% of the country's total arable land, and restrict the land for cultivation of other crops especially vegetable and fruit (Ahmad, 2017).…”
