A holistic approach to humanity’s global use and management of water resources
In »Water: Our Sustainable and Unsustainable Use«, distinguished environmental researcher Edward Bellinger delivers an unbiased and scientifically accurate exploration of every major area of the management and use of water by human beings. Readers will benefit from a coordinated and holistic approach to the subject, including sections covering needs, availability, governance, public health engineering, economics, the potential effects of climate change, water management, and sustainability, allowing the reader to understand the big picture of global water use under conditions of declining water resources.
Assuming only basic knowledge in hydrology, »Water: Our Sustainable and Unsustainable Use« is international in scope and includes case studies from across the globe.
The book also offers:
- A thorough introduction to human and ecological water needs and how they interact
- A discussion of available water resources and systemic problems of water quality
- A comprehensive analysis of the human water footprint and factors driving water demand in modern society
- An overview of the technological aspects of drinking water supply and sanitation, as well as the governance and management of water
Edward G. Bellinger is the former Chair of the Department of Environmental Sciences and Policy at Central European University in Vienna (Austria). He is the former Director of Pollution and Environmental Studies in the School of Biological Sciences at Manchester University (UK).
