Monitoring the Complex Dynamics of LULC Change of Tanguar Haor, a Ramsar Site in the Northeastern Part of Bangladesh

Abstract

The bowl-shaped depressions between the natural levees of rivers, mostly found in the wetland of the north-eastern part of Bangladesh are locally known as Haor. This study has tried to find out the dynamics of land use/land cover (LULC) change of Tanguar Haor, a Ramsar Site of Bangladesh between 1989 and 2017. Satellite data from Landsat archive have been used to determine the LULC change and collected primary data through a questionnaire survey used to identify the factors and impacts of LULC change. Post-classification change detection techniques have been applied to evaluate the LULC change, and descriptive statistics are applied for qualitative analysis of primary data as well as other secondary data
