Abstract

Bangladesh is one of the most vulnerable countries to sea level rise due to the climate change. Soil salinity is one of the potential threat to the coastal ecosystem and agriculture which might hinder the country's future food security. Conventional field-based soil salinity monitoring over vast region may not be cost and time efficient. Satellite remote sensing is offering an efficient way to monitor soil salinity via different indices. This study monitors soil salinity in five years interval from 1990 to 2015 using a regression equation which is developed and tested in the same geographical area to calculate soil salinity from Landsat images. The result shows that soil salinity increases significantly in most of the part of the study area in 25 years period. The percentage of very high saline soil is increased from less than 1% in 1990 to 33% in 2015 which is very alarming for the agriculture growth in this area.
