Abstract:

The present study based on primary investigations (focus group discussion, field observation, household interviews etc.), laboratory analyses for soil and water quality (heavy metal test, pH, salinity, electricity conductivity, particle size analysis etc.) and secondary materials (remote sensing data, satellite images analysis etc.) reveals that due to poor drainage system and continuous shrimp farming at Chandipur Village under Debhata Upazila of Satkhira District, salinity level of both soil and water are increasing. In addition, PH, salinity, electrical conductivity of soil and water have been found in a very critical condition. Different types of heavy and toxic metals such as Na, Fe, Cr, Zn, Ni, and Pb have been detected in ghers’ soil. However, to reduce such toxic concentration in water and soil, measures to introduce drainage system (to control water quality and discharge effluents from ghers), to control the use of fish-feed, to stop further conversion of land into gher and to promote plantation of local species have to be adopted.
