  报告题目:In search of sustainable water management: a case study in the American West

  专家简介:

  Dr. Yangdong Pan is professor of Environmental Science and Management in the School of the Environment at Portland State University, Oregon, USA. His research centers on freshwater ecology and management. Specifically he uses algal assemblages to monitor and assess ecological risk in freshwater ecosystems including lakes, wetlands and rivers. He has participated several national surface water quality programs such as the US Environmental Protection Agency’s Environmental Monitoring and Assessment Programs (EMAP) in the Mid-Atlantic Region and in the western US with a leading role on algal indicators development. Recently, he has been collaborating with Chinese environmental professionals in several projects including the US-China EcoPartnerships Program between the city of Portland and Kunming, a program established by the US State Department and China's National Development and Reform Commission, and water security and ecological risk assessment in the Jiuzhaigou National Park sponsored by the International Science & Technology Cooperation Program of China. He teaches limnology, freshwater algae, ecology of streams/rivers, and univariate and multivariate environmental data analysis.

  报告摘要:

  Freshwater isincreasingly in demand but under threat worldwide. Approximately 80% of the world’s population is exposed to high levels of threat to water security. In the American West, water has always been a vital, scarce, and variable resource. Increasing disturbancein the region including irrigated agriculture, live-stock grazing, mining, and urbanization is further degrading water quality and biological integrity in aquatic ecosystems. In this talk, I will first describe a spatially-balanced and probability-based survey by the US Environmental Protection Agency, which shows that only 51% of the stream and river length in the West can be considered in good condition based on multiple biological indicators. I will then use the Klamath Basin, located in south central Oregon and northern California, as an example to illustrate the key features of a policy landscape shaping water decisions in the basin and address the question faced by the entire West: can conflicted demands on limited water resource be balanced between sustainable human communities and a functional ecosystem?
