Suitability Analysis for Urban Development in Kaduna Metropolis, Nigeria

Abstract

The pursuit of identifying suitable land for urban development in Kaduna metropolis is crucial for enhancing agricultural production, sustainable development, and efficient resource utilization in Nigeria. This research aimed to assess and designate areas with optimal characteristics for urban development. The criteria considered for the suitability analysis encompassed land use land cover, slope, elevation, proximity to the road network, and proximity to water bodies. To establish a comprehensive assessment framework, all criteria were standardized, and the analytic hierarchy process (AHP) was employed to assign appropriate weights to each criterion through pairwise comparison. The weighted overlay technique was subsequently applied to generate a suitability map for urban development. The findings obtained from the weighted overlay analysis indicate that approximately 6% of the study area is marginally suitable, while more than 77% exhibits a moderate level of suitability. Furthermore, approximately 17% of the total land area demonstrates a high level of suitability for urban development. Given the results, it is highly recommended that the Kaduna State Urban Development Agency (KASUPDA) incorporates the use of geospatial technologies such as geographic information system (GIS) and remote sensing, along with the analytical hierarchy process, for conducting comprehensive and reliable land suitability evaluations in any future urban development endeavors within the metropolis. By adopting such an approach, KASUPDA and other relevant stakeholders can make informed decisions, optimize resource allocation, and ensure sustainable urban development in Kaduna metropolis.
