Available in PDF, EPUB and Kindle. Book excerpt: Environmental flows (e-flows) are intrinsically related to water security and water management: when the remaining flow of a river after upstream withdrawals is not enough to safeguarding ecological river functions, the basin is at extreme risk of water scarcity, which indicates that the water management is failing. To test this, we computed water stress indices (WSIs, computed as the ratio of withdrawals to water availability) for 277 basins in Chile, under two water-use scenarios: (i) WSI max , where withdrawals correspond to the maximum consumptive water allowed by the current law, and (ii) WSI alloc , where withdrawals correspond to the actual allocated consumptive water uses within the basins. We diagnose the water allocation system in Chile (defined by the Chilean Water Code) by assigning risks of water scarcity to the computed WSIs, and by contrasting the e-flows protected by law with those safeguarded by water management systems from six other countries.The Chilean Water Code incorporated the protection of minimum e-flows in 2005, but establishing that these do not exceed 20% of the mean annual streamflow, except in some exceptional cases. This limit is significantly lower than those used in other countries, where 20% to 80% of the mean annual streamflow are protected. This turns out in WSI max values between 80% and 100% in all basins, well above the threshold associated with over-committed basins under extreme risk of water scarcity (70% typically). The actual allocated withdrawals lead to contrasting results: about 70 % of the basins show low water scarcity risk (WSI alloc

Download or read book The Human Face of Water Security written by David Devlaeminck and published by Springer. This book was released on 2017-03-09 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume collects essays from academics and practitioners from a diversity of areas and perspectives in order to discuss water security at various levels and to illuminate the central idea of water security: its focus on the individual. Beginning with the big picture, this book aims to illustrate the depth of the water security crisis and its interconnections with other aspects of societal development. It particularly draws a connection to the 2030 Agenda for Sustainable Development, and discusses that challenges faced in meeting the 17 sustainability development goals (SDG) by the year 2030. Moving from international to domestic and community perspectives, this book provides a unique analysis of issues and solutions to the water issues we face today in light of the ever looming global changes brought on by climate change. Over the past few decades the recognition of our common need for water has increased, as policymakers have sought to place more focus on the individual within policy. After the recognition of water and sanitation as a fundamental human right by the United Nations General Assembly in 2010, there is increasing recognition of the individual as the building block for the struggle for water security. This reality also intersects with adverse impacts of global climate change, and the book responds to the broader question: will clean and safe water be available where we need it and when we need it in the future?
