State of Water Resources System (WRS)
The traditional approach to management of the Water Resources System (WRS) in Bangladesh has been on structural interventions designed for flood protection primarily; Major interventions since 60's typically aimed at flood control, drainage and irrigation and diversion of dry season flows beyond borders. For the time being these interventions within country met the immediate need for more food production, but gradually these gave rise to unexpected problems of increased flood heights, water logging, drainage congestion, interruption of the ongoing cycle of nutrient replenishment from inundation and deposition, impediments to navigation, and destruction of habitat for the migration and breeding of native fish species etc. In the recent time due to population growth, urbanization and industrialization new problems of water quality, reduction of flood flow areas and flood retention areas, drainage constrictions, encroachments around urban centers are new challenges or impediment to proper water management.
More recently, increasing emphasis has been placed on other kinds of management interventions, including flood warning systems, flood proofing of buildings and infrastructure, and adaptive responses to hazardous conditions. New laws are being issued for effluent discharges, protection of scarce both ground and surface water resources, protection of water bodies to remedy the deteriorating situations. Continuous accumulation of information and assessment of the state of water resources, including key trends, changes over time, the main characteristics of the water resources system (WRS) is required for early warning for possible interventions and protection of environmental “hotspots” in the WRS. Routine assessment of the water resources system is therefore one of the mandate of WARPO along with the monitoring and evaluations of the impacts of the interventions. A periodical report on the State of the Water Resources System (SoWRS) for Bangladesh will be published as supplement to the report on the state of environment in the country.
