A Spatiotemporal Analysis of Urban Densification in an Organically Growing Urban Area

Abstract

Urban densification has attracted much attention in recent times, particularly in addressing certain urban problems such as urban sprawl and promoting compact development, though problems of unplanned densification are yet to be addressed in the literature. This paper examines space and time dynamics of urban densification, where patterns and changes in the residential densification of Bida urban area in Nigeria are assessed. The study relied on point features representing buildings for the years 2008, 2013, and 2018 digitized using ArcGIS 10.6. The data were analysed using Point Density spatial method to develop the spatiotemporal models which were further reclassified into three categories: low, medium, and high densities, respectively. The paper has found out that residential densities increase along the urban-rural gradient with clear evidence for unplanned urban densification as a result of the organic growth. Therefore, there is the need for planned densification in urban development which can curb the increasing residential density that reduces green and open spaces.
