Title: A comprehensive intergrated management approach for water resrources management
Minh Ngoc Trinh
Integrated Water Resources Management (IWRM) takes the view of sustainable development and applies it to the water sector. The study identified the indicators was constructed classifying them according to the environment indicators and parameters. These are resource availability stress (RS), water development pressure (DP), ecological heath (ES), and management capacity (MC). The studied area were divided for the 12 sub-regions for Thach Han river basin (Quang Tri, Vietnam) and illustrated in vulnerability map. The results of assessing the vulnerability of sub-regions found that all sub-regions are highly vulnerable. However there is still differentiation in vulnerability levels. Dong Ha city, The coastal plain of Gio Linh coastal plain, Trieu Phong coastal plain is under high water pressure. Due to economic development, the demand for water is high, susceptible to local pollution, and water is contaminated with alum and lime, which fail to ensure environmental hygiene. For midlands and mountainous region, water supply conditions are still poor, or in other words, local people have no access to clean water. In the areas of developed fisheries and animal husbandry, water is susceptible to contamination system of breeding facilities or aquatic environment hygiene which fail to meet relevant requirements. Forest development is currently at low level. The results demonstrate the interaction between different regional resources and activities and are one of the decision makers to adopt policies for each sector in this region.
