Land Cover Change in Jakarta


2021 | Tools: Google Earth Engine, ArcGIS


As part of a larger research project that investigates the political ecology of water insecurity in Jakarta as a sinking city, I explored the land and water dynamics measured through changes in land cover during major urbanization development phases in Jakarta.
Jakarta’s rapid urbanization have been characterized by the tension between providing space for people and making room for water to reduce the impact of urban stormwater runoff.



Land Cover Change in Jakarta 1989-2020



Using satellite imagery and remote sensing techniques, I classified land cover types into built-up area, non-built-up area, and waterbody. Employing spatial statistics, these land cover types were further quantified as baseline information for analysis of development in areas identified as flood-prone.
