The Use of Remote Sensing and GIS Technology in Supporting Ecoregion Management
Abstract: Coastal areas
provide great benefits for human lives. In many isolated islands, coastal
ecosystem provides food and building materials extracted from coastal
vegetation e.g. mangroves. Therefore, it is essential to ensure the
sustainability of the coastal ecosystem. This study provides data and a map in
supporting the coastal ecoregion management, by using remote sensing satellite
imagery, GIS technology, and field observation. Remote sensing and GIS data
were obtained from Google Earth and analysed by ArcGIS. The combination of both
laboratory and field work were carried out to provide a broad picture of the
coastal area in Jefman Island, Raja Ampat, West Papua. The result of this study
showed various habitats and vegetation in the Jefman seabed area. It also
demonstrates that the abundance and diversity of coral reef and reef fishes are
the major community constructing the island, amounting 22% coral cover with 12
families and diversity index 1.20 – 2.52 for reef fish with fish density about
231 ind/50 m2. Furthermore, other communities such as seagrass, seaweed, and
mangrove are also briefly explained, as they also play a greater role in
supporting the whole coastal ecological system. Based on map data analysis, we
found a particular area that urgently needs to be protected. Remote sensing and
GIS technology were found useful to help the manager to design coastal
management strategies in the future.
