The latest insights on saltwater intrusion in coastal Bangladesh
Today we’re celebrating the newly published article of our colleague Isfat Bhuyan! His research takes us to the south-central coast of Bangladesh. Bangladesh is blessed with many islands along the Bay of Bengal. Climate-induced changes such as sea level rise and a changing water balance may affect the agroecosystems of these areas through saltwater intrusion. However, more research is needed on the variation in salinity levels.
This study aims to determine the variation of soil and water salinity in time and space along the south-central coast. Soil and water salinity is one of the major hydrological problems for coastal farmers, especially during dry periods (November-May). An increase in soil and water salinity will affect crop production, coastal biodiversity, and human health. So for adaptation against salinity, it is important to know the variations of salinity levels with space and time in the coastal area.
This article presents a lot of new data on soil and water salinity in an area of the world that is vulnerable to saltwater intrusion. We collected many new soil samples and applied stratified sampling techniques to cover all land types and land use patterns in the southern coastal districts of Bangladesh. The findings of this study will help farmers and other stakeholders in developing zone-specific adaptation plans against salinity.
