Spatial transformation in urban periphery: the case of Yogyakarta

The development of Yogyakarta has created large impacts on its urban periphery areas. Trickle-down effects for the surrounding development trigger the emergence of spatial transformation in Yogyakarta's urban peripheries. This study intends to identify spatial transformation in Yogyakarta's urban peripheral by using the spatial analysis method which obtained from the land-use satellite map. Transformation measurement utilizes land use, total population, and economic growth variables in the last ten years (2007-2017). Results show that a spatial transformation was reported from the land use aspect, accounted for 15.22%, due to the reduction in agricultural land due to conversion into the constructed land area, up to 22,82%. From the land use map, the pattern of land-use changes in urban peripheries occurs along with the transportation networks. Population growth and economic growth also showed increasing rates at 5,06% and 9%, respectively. From all variables used in the analysis, it is interesting to find that majority of the urban periphery areas in Yogyakarta experiences a low transformation level, mostly located in the Sleman regency. Furthermore, this study provides several insights from the spatial transformations in the urban periphery to conceive some urban policies regarding urban agglomeration.
