Over the last 45 years, salinity has increased around 26 percent in the coastal region of Bangladesh.
Salinity causes a hostile environment for the normal crop production throughout the year in the coastal belt of Bangladesh.
As a result, the reduction of food crop production in the coastal region has significant impact on the national economy of Bangladesh.
This conductivity increases the salt in soil and water across the coastal belt in Bangladesh.
Due to increasing soil and water salinity, people in the communities of the Kalapara coastal regions have been suffering from a scarcity of safe water for the production of crops, fish, and livestock.
The majority of people living in the coastal community are dependent on the agricultural production of crops, fish, and livestock.
For this reason, crop production has been negatively affected each year for many decades across the coastal belt of Bangladesh.
However, people have also converted fresh water areas through intrusion of saline water for shrimp culture, increasing the salinity in the surrounding areas and damaging the grazing areas of livestock.
As women drink less water, high blood pressure, heart and kidney diseases are common, which affect the health of new-born babies.
About 70 percent of people in the region depend on pond water for drinking and domestic uses.
