Coping with challenges in major water issues of Bangladesh
This review article aims at depicting the most delicate water issues and challenges in Bangladesh perspective along with their coping strategies at the field level. In 1970s, the changeover of surface water to groundwater in domestic uses had drastically decreased the death rates due to waterborne infections; although, new incidences of severe illness popped up due to arsenic poisoning in groundwater. Furthermore, the organic matter contamination in groundwater was found to affect the arsenic removal efficiency to around 50% through both chemical and biological processes. Nevertheless, groundwater mining poses an immense problem in various parts of the country. A recent survey showed a sharp drop of groundwater level around 35m within one decade in Dhaka city and an average maximum declination of 0.23 meter/year in Barind Tract areas. In this context, an Integrated Water Resources Management (IWRM) strategy has been adopted by the Barind Multipurpose Development Authority (BMDA) to use the limited water resources in a sustainable manner. Moreover, the coastal zone salt affected areas were found to be increased 26.7% during 36 years. On the other hand, the Ganges water diversion project at Farakka severely affected the downstream part in Bangladesh through hampering the crop production, aquatic resources, industrial activities, terrestrial & marine ecosystem, etc. Salinity intrusion have been tremendously grasping the inland more than 300 km of coastal boundary because of inadequate fresh water flow from the Ganges for flushing out its distributaries that empty into the Bay of Bengal. This increasingly high level of salinity is perceived to be a great risk for sustaining the world’s largest mangrove forest “the Sunderbans”. To cope with this situation, an adaptation pathway map was developed for the most salinity affected coastal systems. Finally, a conceptual framework for conjunctive use of various water resources has been proposed to meet up the various water demands optimally in the regional context.
