Water Consumption And Sustainable Water Resources Management

This report presents the discussions and conclusions of the OECD workshop on sustainable water consumption. It examines progress made on a range of key water policy issues and examines some of the more innovative attempts to put into practice a wider vision of integration.

Sustainable Water Resources Management presents the most current thinking on the environmental, social, and political dimensions of sustainably managing the water supply at local, regional, or basin levels.

Contributing to the growing debate on the need for sustainable water use and management, with concrete examples of new approaches, concepts, arguments, methods and findings which illustrate how this can be achieved, this book will be attractive for large groups of readers familiar with one or more of the themes it tackles, and to the general public. Within this context, the book makes use of many tables and graphics, which bring the many messages together. This approach is intended not only for those working on water matters (e.g. bureaucrats, water managers, policymakers, journalists, etc.) and interested in water management issues and sustainability at large, but also for students of water management, water politics, environmental policy, water economics, water engineering and sustainability studies. Located at the crossroads of two key phenomena: sustainability and water, this book brings forward academic research and discussions on water efficiency, new technologies, and the water-agriculture nexus. It also benefits readers by tackling matters related to trans-boundary cooperation on water (including rainwater) and river-basin management, pricing issues, participatory water management, and the role of women in sustainable water use, amongst others.

The book explores the geo-chemical, physical, social and economic impacts of climate change on water supplies. It contains examples and case studies from a wide range of countries, and addresses the need to promote sustainable water use across the world.

Population growth, increasing living standards, and rapidly changing climate have resulted in an increasing demand for freshwater, accelerating the water degradation challenges. There is a compelling need to minimize water consumption and develop approaches to effectively manage existing water resources. On a positive note, water resource management strategies discussed in this book present innovative ways to conserve both quality and quantity. Chapter 1 discusses decentralized water management approaches for intervening the urban water cycle to minimize the environmental and socioeconomic impacts. This chapter concludes with a need to use a suite of tools based on decision support systems for managing urban water resources. Chapter 2 discusses the need for assessing suitability of various types of models for a specific scenario based on the required level of complexity. This chapter discusses in detail the underlying criteria behind model selection, validation, and uncertainty analysis. Urban watersheds can be more challenging compared to natural watersheds. The urban watersheds include parking lots, roads, and developed structures, all of which contribute to a myriad of anthropogenic pollutants through stormwater runoff. Computer-based models can be used to study water quality issues and to develop a plan to manage watershed level resources. Chapter 3 compares pros and cons of the state-of-the-art watershed models used for managing water resources. Numerical simulations can be performed to compare the current and future water quality scenarios of a given watershed and to estimate the impact of potential water resource management strategies. Chapter 4 presents a case study of an urban region in Hanoi, Vietnam. Water evaluation and planning simulation tool was used to predict the trends and drivers of wastewater generation. Considering rapidly changing climate and associated weather impacts, it is critical to secure water resources in addition to dealing with the water quality issues. Chapter 5 suggests that climate change models and watershed and precipitation models should be jointly used in order to capture uncertainties in ecological functions, energy and food production and water supply sources. Chapter 6 presents a water use estimation and management tool that examines the effect of climate change and drought conditions on water supplies to ensure adequate buffalo forage. Sustaining both buffalo forage and water supplies during drought conditions requires preparedness and adaptation in response to unfavorable conditions. Finally, water reuse can alleviate the stress on available water resources. For example, effluents from wastewater treatment plants and desalination plants can be treated and reused for managing water crisis. Chapter 7 emphasizes that it is critical to optimize both economical and sustainability parameters during treatment of wastewater effluents and desalination concentrate. In certain cases, valuable metals can be recovered from the concentrate.

This book is a printed edition of the Special Issue "Water Governance, Stakeholder Engagement, and Sustainable Water Resources Management" that was published in Water

This book discusses different aspects of water resources, ranging from hydrology and modeling to management and policy responses. Climate changes and the uncertainty of future hydrological regimes make sustainable water resources management a difficult task, requiring a set of approaches that address climate variability and change. The book focuses on three main themes: hydrological changes, adaptive decision-making for water resources, and institutional analysis and risk management. It discusses the applications and limitations of climate change models and scenarios related to precipitation projection, which predicts to the future availability of water. It also offers interesting examples from around the globe to describe the policy options for dealing with climate change. Addressing emerging issues that need to be resolved and techniques that can be applied for sustainable climate-change-sensitive water resources protection and management, this practical, state-of-the-art reference book is a valuable resource for researchers, students and professionals interested in sustainable water resources management in a changing climate.
