Download or read book Next Generation Earth System Prediction written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-08-22 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the nation's economic activities, security concerns, and stewardship of natural resources become increasingly complex and globally interrelated, they become ever more sensitive to adverse impacts from weather, climate, and other natural phenomena. For several decades, forecasts with lead times of a few days for weather and other environmental phenomena have yielded valuable information to improve decision-making across all sectors of society. Developing the capability to forecast environmental conditions and disruptive events several weeks and months in advance could dramatically increase the value and benefit of environmental predictions, saving lives, protecting property, increasing economic vitality, protecting the environment, and informing policy choices. Over the past decade, the ability to forecast weather and climate conditions on subseasonal to seasonal (S2S) timescales, i.e., two to fifty-two weeks in advance, has improved substantially. Although significant progress has been made, much work remains to make S2S predictions skillful enough, as well as optimally tailored and communicated, to enable widespread use. Next Generation Earth System Predictions presents a ten-year U.S. research agenda that increases the nation's S2S research and modeling capability, advances S2S forecasting, and aids in decision making at medium and extended lead times.
Download or read book Water Security in Asia written by Mukand Babel and published by Springer. This book was released on 2021-05-22 with total page 797 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book assesses the current water-security situation in Asia. The thematic areas of the book discuss the United Nation’s sustainable development goals with a particular focus on Goal 6 (“Ensure availability and sustainable management of water and sanitation”) and Goal 13 (“Take urgent action to combat climate change and its impacts”). Asia has been facing a number of water-related challenges for decades due to multiple factors such as increasing population, socio-economic development, urbanization and migration, and climate change now poses an additional threat. While significant efforts have been made by governments in Asia, much more work is needed to make Asian societies water-secure. Given its multi-disciplinary approach, the book is a valuable resource for researchers involved in the further development of water-security concepts, approaches, and methodologies. In addition, it helps policymakers, planners, and practitioners to formulate sustainable water- security enhancement strategies grounded in sound scientific evidence to protect human well-being.
