Water Matters: Achieving the Sustainable Development Goals presents a compilation of water scenarios and their relationship to multiple facets of life as water forms a nexus with food security and energy resources, thereby forming one of the fundamental pillars of sustainable development. The thematic topics focus on studies of achieving individual sustainable development goals, primarily on safe and sustainable drinking water availability, the role of water in sanitation, transboundary water, and water in the ecosystem. Each chapter presents a case study to enable a holistic review of the topic and provide insight for further research. The book integrates the knowledge on global-scale water reviews to local-scale case-studies and is ideal for hydrologists, hydrogeologists, and water managers in environmental and Earth sciences.
