Mangrove Cover in Jakarta: An Output of GNRM Program on Strengthening Lecturers and Students Awareness to the Sustainability of Jakarta Coastal Environment

Abstract

Jakarta is very vulnerable to erosion and tidal flooding. Mangrove forest on the Jakarta coastal has a very important role because it can reduces the damage caused by seawater tidal flooding and erosion. However, the existence of mangrove forests is threatened by various natural factors, human activities and a combination of both. Given the important role of mangroves for the city, data and information on temporal changes in the distribution of mangrove cover in this area need to be monitored annually to evaluate changes in cover holistically. Therefore, this study was conducted to detect changes in the spatial and temporal distribution of mangroves on the Jakarta coastal. Landsat 7 ETM satellite image data from 2014 to 2018 were analyzed using medium resolution combined with visual interpretation and literature review to detect changes in mangrove areas. Mangrove forest cover was estimated at 111.58 hectares in 2014 and decreased to 103.84 hectares in 2018. That means Jakarta has lost 7.74 hectares over 4 years. This review article will also discuss the main factors that influence, changes in area, the impact of Jakarta Bay reclamation on North Jakarta's mangroves.
