Study about factors influencing transition of green open spaces based on analysis of land use in Depok City, West Java, Indonesia

Most green open spaces in Jakarta, the capital city of Indonesia, are susceptible to conversion into urban use. In Jakarta, land development is progressing to the point where there is no room for additional land development, resulting in a shift to land development in other cities, especially the urban areas surrounding Jakarta, Jabodetabek. This study focused on land development in Depok City located south of Jakarta. Depok is influenced strongly by land development in Jakarta, and further economic growth is expected. The purpose of this study is to reveal the changes in the area of green open spaces to investigate the transition of green open spaces in Depok and to identify the factors influencing the transition of green open spaces in Depok. ERDAS 9.1 Software was used to analyze the changes in the area of green open spaces in 1995–2015. To identify the factors influencing the transition of green open spaces, binomial logistic regression analysis was used. It was revealed that the area of green open spaces has rapidly decreased from 2005 (9789.28Ha) to 2015(5157.80Ha) in Depok. The results of logistic regression analysis showed Logit Y = 2.575 − 0.118 X1 − 0.012 X2. Two factors particularly influenced the transition of green open spaces, the proximity to educational areas or main roads was associated with reductions in green open spaces.
