Study About Factors Influencing Transition of Green Open Spaces Based on Analysis of Land Use in Depok City, West Java, Indonesia

Abstract

This study focused on land development in Depok City located south of Jakarta. Although Depok enjoys a tropical climate, it is necessary to consider the distribution of land use within the city, especially green open spaces. Depok is a commercial center and a public utilities center, where water is stored to supply ground water as buffer city of Jakarta. Moreover, it is a hotspot of education and residential area development. Depok is influenced strongly by land development in Jakarta, and further economic growth is expected. The purpose of this study is to understand the transition of green open spaces and land use types in Depok to reveal the changes in the of area of green open spaces in Depok and to identify the factors influencing the transition of green open spaces in Depok. To identify the factors influencing the transition of green open spaces, binomial logistic regression analysis was used. The dependent variable was the area of green open space converted into non-green open space, and the independent variables included distance from commercial facilities, distance from industrial areas, distance from educational areas, distance from hospitals, distance from rivers, distance from lakes, distance from main roads, distance from a highway, distance from a highway entrance, distance from a railroad station, and distance from inundation-prone areas. It was revealed that the area of green open space has rapidly decreased in Depok, especially from 2005 to 2015. Two factors particularly influenced the transition of green open spaces, where a greater proximity to educational areas or main roads was associated with a greater reduction in green open space. Also, the distance from hospitals and lakes were associated with the maintenance of green open spaces in Depok. For residents, convenience is improved in areas close to educational areas or main roads; therefore, it is conceivable that buildings such as housings are increasing accordingly in such areas.
