中文简介:
由 jay famiglietti 博士、地球系统科学和土木工程 & 环境工程教授以及 uc 水文建模中心主任主持的 cusa 可持续发展研讨会。记录于2011年4月6日。在过去十年中, 对地球水循环的卫星观测, 特别是来自美国航天局重力恢复和气候实验飞行任务的卫星观测, 对最近淡水供应的变化提供了前所未有的看法。特别是, 水库蓄水和地下水使用等水管理做法的人类指纹非常清楚, 并为气候、水、粮食和经济安全提出了许多重要问题。此外, 全世界地下水含水层的枯竭及其跨界性质表明, 在不久的将来, 冲突可能会大大加剧。在这次研讨会上, 我将回顾 grace 调查团如何观察世界水资源的基础知识、评估团自2002年启动以来提供了哪些新信息, 以及供水对未来的影响。将强调水压力的几个热点, 包括对区域安全和冲突的影响。
课程简介: A CUSA Sustainability Seminar delivered by Jay Famiglietti, PhD, Professor, Earth System Science and Civil & Environmental Engineering, and Director, UC Center for Hydrologic Modeling. Recorded on April 6, 2011. Over the last decade, satellite observations of Earth's water cycle, in particular, those from NASA's GRACE (Gravity Recovery and Climate Experiment) mission, have provided an unprecedented view of recent changes in freshwater availability. In particular, the human fingerprint of water management practices such as reservoir storage and groundwater use is abundantly clear, and raises many important issues for climate, water, food and economic security. Moreover, the worldwide depletion of groundwater aquifers and their transboundary nature points to the great potential heightened conflict in the very near future. In this seminar I will review the basics of how the GRACE mission observes world water resources, what new information the mission has provided since its launch in 2002, and what the implications are for the future of water availability. Several hotspots for water stress, including implications for regional security and conflict, will be highlighted.
