The gray mangrove (Avicennia marina (Forssk) Vierh) constructs one of Bahrain's most critical ecosystem, severly deteriorating, which has been severely deteriorated by increasing anthropogenic pressures. This study aimed to assess the spatiotemporal changes in habitat around Tubli Bay, Kingdom Bahrain, over last 50 years through achieving following: (1) detect progressive reduction cover using Geographic Information Science and Systems (GISs) techniques remote sensing data, (2) estimate above–below ground (AGB-BGB) carbon sequestered mangroves a GIS-based spatial analysis approach, (3) potential emission from loss original habitats. Various GIS remotely sensed data were employed study, including high-resolution satellite images Worldview-3, Worldview-2, IKONOS, QuickBird, coupled with true-color orthorectified aerial photographs. Additional was acquired fieldwork ancillary maps. Image processing conducted ENVI 5.5 Software. ArcGIS 10.8 used for digitizing areas all imagery. final maps calculate area due land reclamation activities. Our results indicated that Bahrain lost more than 95% natural 1967 2020. extent area's net reached 280 ha during 1967–2020, as it declined 328 48 primary cause decline associated urban development. rates causes varied both spatially temporally.
