Monitoring Changes in Land Use Land Cover and Ecosystem Service Values of Dynamic Saltwater and Freshwater Systems in Coastal Bangladesh by Geospatial Techniques

Assessing and modeling the changes in land use cover (LULC) patterns associated ecosystem service values (ESV) has become an important global agenda for formulating sustainable management policies. Taking coastal region of Bangladesh (CRB) as a case study, we utilized remote sensing GIS techniques to analyze Landsat data 1999 2019 estimate effect LULC on ESVs. The classification, ESV quantification, spatial variations were performed by semi-automated per-unit value transfer, autocorrelation techniques, respectively. First, between 2019, altered dramatically (agricultural wetlands decreased, while all other types increased). Second, total decreased 1.87%, which was mostly attributed 70% growth both rural settlement aquaculture/saltpan, 30% decline agricultural wetlands. Third, significant correlation moderately high clustering observed, consisted mangrove forests, waterbodies, wetland zones. Both high-high low-low increased, but outliers remained unchanged. Conserving should be prioritized future plans CRB meet ever-increasing food demands, control natural conversion, make sustainable.
