Once a purely technical sub-discipline of hydrology, water quality management is now a social and political discipline, with concerns ranging from ensuring adequate health standards to preserving biological diversity and ecosystem integrity. This book goes beyond the technical manuals and specialty publications to provide support and guidance for the everyday decisions made by water-quality managers. Water Quality: Management of a Natural Resource addresses the rarely touched upon social, biophysical, land-use and policy considerations, which reflect the issues that confront managers and decision-makers. In a series of incisive reviews, experts address key topics in modern water resource management and case studies illustrate the successes and failures of past management efforts. Water Quality: Management of a Natural Resource develops and presents a management view requiring an awareness of: the social context of management, new ecological theories, and how policy is implemented in different situations and countries.

Water resources in Mexico are threatened by scarcity, pollution and climate change. In two decades water consumption doubled, producing water stress in dry seasons and semi-arid and arid regions. Water stress rises due to physical and economic stress. In seven parts a multidisciplinary team analyzes hydrological processes in basins and their interaction with climate, soil and biota. Competing water use in agriculture, industry and domestic needs require savings, decontamination processes and desalination to satisfy the growing demand. Water quality affects health and ecosystems. This creates conflicts and cooperation that may be enhanced by public policy, institution building and social organization.

The quality of drinking water is paramount for public health. Despite important improvements in the last decades, access to safe drinking water is not universal. The World Health Organization estimates that almost 10% of the population in the world do not have access to improved drinking water sources. Among other diseases, waterborne infections cause diarrhea, which kills nearly one million people every year, mostly children under 5 years of age. On the other hand, chemical pollution is a concern in high-income countries and an increasing problem in low- and middle-income countries. Exposure to chemicals in drinking water may lead to a range of chronic non-communicable diseases (e.g., cancer, cardiovascular disease), adverse reproductive outcomes, and effects on children’s health (e.g., neurodevelopment), among other health effects. Although drinking water quality is regulated and monitored in many countries, increasing knowledge leads to the need for reviewing standards and guidelines on a nearly permanent basis, both for regulated and newly identified contaminants. Drinking water standards are mostly based on animal toxicity data, and more robust epidemiologic studies with accurate exposure assessment are needed. The current risk assessment paradigm dealing mostly with one-by-one chemicals dismisses the potential synergisms or interactions from exposures to mixtures of contaminants, particularly at the low-exposure range. Thus, evidence is needed on exposure and health effects of mixtures of contaminants in drinking water. Finally, water stress and water quality problems are expected to increase in the coming years due to climate change and increasing water demand by population growth, and new evidence is needed to design appropriate adaptation policies. This Special Issue of International Journal of Environmental Research and Public Health (IJERPH) focuses on the current state of knowledge on the links between drinking water quality and human health.

Why is the bread basket of Arabia importing more water via grain than is pumped locally by all sectors and why does nobody notice? How can the same water be sold to different users at prices varying by five orders of magnitude? How can the biggest names in development throw millions of dollars at supplying water to a city and not an extra drop has emerged? Why do some of the wealthiest companies in the Middle East and their multinational associates get away with polluting water resources? This book presents the complex and fascinating account of Ta'iz, Yemen, a city embroiled in severe water stress as a consequence of environmental degradation, political facades, conflicting legal systems, military intervention and institutional incompetence. The result is a remarkable, compelling and controversial book which will be essential reading for academics, development agencies and NGOs around the world.

Based on the water footprint (WF) concept, this book reviews WF-based water stress evaluation methods at the city, provincial and river basin levels respectively. In addition, it explores the factors that influence regional water footprint in the spatial sequence via the extended STIRPAT model. Highlighting the utilization of WF accounting in sustainable water management, one of the book’s goals is to establish the optimization model of water allocation in various industrial sectors. Based on WF accounting, which thoroughly considers the water input for production, the relevant intermediate water inputs, and the water amount for wastewater discharge dilutions, the book provides a wealth of insights for scholars and practitioners with an interest in water resources and environmental management. In addition, it exhibits a scientific plan for regional water resource utilization and allocation, helping relieve regional water shortages.

In the present scenario, stresses induced due to global environmental change have indeed become a focal point of researches and study programmes worldwide. Stress caused to plant life has an important consequence to both, vegetation as such and all other global cycles which sustain this `living earth'. Unlike other already existing works this volume elucidates the plant-pollutant relationship in a manner that defines not only the drastic effects of pollutants on plants but concomitantly highlights the hitherto less focused areas namely phytoindication, phytoremediation and stress tolerant bioaesthetic development, thus concentrating more on plant than pollutant. The book would help understand the magnitude of environmental stress in the coming years and may play a formative role in defining future research and policy areas along with providing impetus to development of newer eco-technologies. The book shall interest both students and researchers of environmental sciences, ecology, forestry and related disciplines as well as persons and organisations engaged in environmental management and eco-conservation.
