Integration Of Gis Technology On Site Suitability Analysis For Mangroves Rehabilitation In The Coastal Areas Of Bulacan - Ilagan, Jharold N,.; Patrice Ann N. Casino (Magalang, Pampanga : Pampanga State Agricultural University, 2022)
This study employed qualitative descriptive research design and aimed to know the area of mangroves, mangrove vegetation index, species of mangroves and the area of land that is suitable for mangroves rehabilitation in the five coastal municipalities of Bulacan. The data used in the study are shapefiles of parameters from PhilGIS, Lipad Lidar and Humdata. Also, this study used a raster file of slope data from EarthData Search NASA. The parameters used to conduct the suitable areas are land cover, mangroves area, soil types, Philippine rivers and roads and slope. All parameters are processed using QGIS software to extract the mangroves Suitable areas. According to the finding of the study the total of mangroves areas in the coastal municipalities 3,298,273 sq. the total area of mangrove with high vegetation, medium vegetation and low vegetation is 2,491667 sq. m, 802,081 sq. m and 2108 sq. m respectively. There nine (9) of mangroves species under three (3) in the coastal of Bulacan according to International Union for Conservation of Nature (IUCN) all species are decreasing in number. The predicted suitable land area for mangroves rehabilitation is about 554,669 sq. m in, the study reveals that the suitable land for mangroves rehabilitation is small. The researcher highly encourages to prioritize mangrove rehabilitation in the mangrove areas with low vegetation and utilize the QGIS produced maps for mangroves rehabilitation planning.
