Description
Summary:The formation of the Jakarta Bandung Mega-Urban Region (JBMUR) has created a rapidly urbanized corridor, the JBMUR south conurbation corridor. Due to its geographical location, the expansion process in the JBMUR south conurbation corridor has caused significant social, economic, and environmental problems. This study explores and quantifies the impact of the urban expansion of the JBMUR on its south corridor, mainly on the spatial pattern and the form dynamics based on the land-use changes process, using landscape metrics and its implications on planning policy. The metrics used in this study describes a few patterns and form characteristics: density, clustering, connectivity, and shape. Those metrics are then quantitatively measured using the FRAGSTATS Urban Expansion Intensity to measure the expansion rate in four of the JBMUR South Conurbation Corridor urban areas. The result shows that the urban areas grow significantly from the core area and expand outside with the following pattern: increased urban density, less compact, and the two urban areas becoming closer/more connected. This growth intensity and pattern are happening due to the misalignment of the planning policies in the municipalities of the south corridor. It is needed for any future planning policies to mitigate these problems and create a robust plan to maintain the sustainability of the JBMUR South Conurbation Corridor as a whole.
