U.S.-Vietnam Planning Visit: Developing Integrated Hydrologic-Economic Model for the Dong Nai Basin

0527435梅尔该奖项支持计划访问，使教授亚历克斯梅尔在密歇根理工大学会见邓清哈教授在越南胡志明市的龙南大学。 此次访问将有助于制定一项合作计划，为同奈河流域（DNRB）开发一个综合水文经济模型。 它是越南最大的国家河流流域，也是越南南部的经济中心。 DNRB水资源管理面临的挑战包括快速的工业发展和城市增长，这对城市工业用水需求和水电生产造成了越来越大的压力。 与此同时，这些用途直接与农业部门竞争。 工业废水和生活废水的数量越来越多，这些废水未经事先处理直接排入水体，使问题更加严重。 尽管对多用途水库进行了几次大规模投资，但由于缺乏财政资源、下游需求不断增加、盐碱化问题日益严重、灌溉系统管理不善以及该区域水资源项目之间缺乏协调，该地区的灌溉潜力尚未得到充分发挥。 为了帮助支持协调DNRB的水管理，需要更好地了解水的供应、需求、质量及其在各种用途中的价值。 此外，了解替代政策工具在缓解未来可能出现的水资源短缺和流域水质持续恶化方面的作用，将有助于在灌溉、水电开发和城市供水需求之间更适当地分配稀缺资源。 国际粮食政策研究所（IFPRI）为DNRB开发了一个综合经济水文模型。 在这次访问期间，合作者将组建一个负责开发和应用模型的团队，并计划进一步的工作，如数据收集，调查和设置分析场景等。该项目的长期目标是：（1）通过纳入地下水和水质模型，改进IFPRI_DNRB模型作为决策支持工具;（2）利用该模型作为一种工具，在流域水资源利益相关者之间达成共识。

0527435MayerThis award supports a planning visit to enable Professor Alex Mayer at the Michigan Technological University to meet with Professor Dang Thanh Ha at Long Nam University in Ho Chi Minh City, Vietnam. The visit will help develop a collaborative plan for developing an integrated hydrologic-economic model for the Dong Nai River Basin (DNRB). It is the largest national river basin and also the economic center of southern Vietnam. The challenges facing water management in the DNRB include rapid industrial development and urban growth, which is placing growing pressure on urban-industrial water demands and hydropower production. At the same time, these uses directly compete with the agriculture sector. The problems are compounded by an increasing amount of industrial effluents and domestic wastewater, which are discharged directly into the water bodies without prior treatment. Despite several large investments in multipurpose reservoirs, the full irrigation potential of the area has yet to be achieved, due to lack of financial resources, increasing downstream demands, growing salinity problems, poor management of irrigation systems, and lack of coordination among water resources projects in the region. In order to help support coordination of water management in the DNRB, a better understanding of water supply, demand, quality, and its value in various uses is needed. Moreover, understanding the role of alternative policy instruments in alleviating likely future water shortages and continuing deterioration of water quality in the basin will help allocate scarce resources more appropriately across irrigation, hydropower development, and urban water supply demands. The International Food Policy Research Institute (IFPRI) has developed an integrated economic-hydrologic model for the DNRB. During this visit the collaborators will assemble a team responsible for developing and applying the model and plan for further work such as data collection, surveys, and setting scenarios for analysis, etc. The long-term goals of the project are to (1) improve the IFPRI_DNRB model as a decision-support tool by incorporating groundwater and water quality models; and (2) to use the model as a tool for achieving consensus among those with interests in the basin's water resources.
