Water and soil salinity is one of the serious problems of the coastal region of Bangladesh. It affects production of crops, human heath, fisheries etc. Around 13% of the total urban population live in coastal zones and of these, more than 75% live in Asia. The objective of this study was to assess the coastal salinity over the years of Bagerhat and Satkhira, two south-western districts of Bangladesh. The soil and water salinity data of these areas was collected over 2000–2009 period. The Landsat TM image of these areas were analyzed by GIS. Key Informant Interviews (KII) and field sample collection was also accomplished. Here the data from 2000–2009 were analyzed and revealed that soil and water salinity increased over this period (2000–2009). A landsat image of 2016 (Fig. 1) was developed and showed that there was a decrease in vegetation and bare land.
