Water is a precious resource essential for all forms of life, and although there is plenty of water to meet the demand for the present population – and even for a projected population of 9 billion – there is significant spatial and temporal variation in its distribution. This results in water rich and water poor countries, water-related conflicts, and unsafe drinking water, a major killer identified by the World Health Organization (WHO). Water for Life: Drinking Water, Health, Food, Energy Nexus covers these issues, highlighting the multi-facted uses and importance of water in life: water resources, chemistry of water, drinking water, and the links between water and health, food, irrigation, soil, energy, transport, industry, recreation, disasters, and conflicts. The book is accessible and clear, with technical elements. It is ideal as a background supplementary text to support more specialist study across civil engineering, geography, and social sciences, and will guide readers to see the big picture of environmentally sustainable water management for all human and other biotic lives.
