Abstract (Swedish)
Mangrove forests are highly productive and vital ecosystems within the tropical and subtropical latitudes. They are considered biodiversity hot spots and hosts ha vast variety of species, both terrestrial and marine, and they are also found to be one of the most productive carbon pools in the world. Mangroves additionally provide coastal communities with timber but also important shelter from tsunamis and storm surges. Despite this, mangrove forests have undergone a rapid decline globally, resulting in vulnerable coastal communities and ecosystems. It is thus crucial to investigate and monitor the change of mangrove extent and density.

Mangrove forests are highly productive and vital ecosystems within the tropical and subtropical latitudes. They are considered biodiversity hot spots and hosts ha vast variety of species, both terrestrial and marine, and they are also found to be one of the most productive carbon pools in the world. Mangroves additionally provide coastal communities with timber but also important shelter from tsunamis and storm surges. Despite this, mangrove forests have undergone a rapid decline globally, resulting in vulnerable coastal communities and ecosystems. It is thus crucial to investigate and monitor the change of mangrove extent and density.

In this study, the mangrove extent in Busuanga municipality, Philippines, between the years 2020 and 2024, has been analyzed by using a supervised classification method called Random Forest and Sentinel-2 satellite imagery. The classification was done in ArcGIS where the study area was divided into two land cover classes; Mangroves and Other land cover. The overall accuracy of the 2020 classified map was 72 percent, and the overall accuracy of the 2024 classified map was 70 percent. Furthermore, a decrease of 1,613 ha and an increase of 3,417 ha of mangroves was observed in this study, leading to an overall increase of 1,804 ha.

This study can be seen as a guideline to future research, where a focus should lie on creating a more accurate classification, which in turn could assist restoration planning and projects. (Less)
