In just an hour or two, the reader can pick up the fundamentals on key themes right from the basics of the water molecule through for example to water's linkage to so many human activities and the concerns around climate change, virtual water, and hydrological change. There are some technical parts, such as a few pages on the basics of hydraulics, but so too is there reference to water's cultural importance, a little poetry, and an imaginative '100 ideas' section (whose 'Five organizations to check out if you care about the issues raised in this book' include IWA). There is clearly a wealth of knowledge behind this perspective. Valuable concepts are woven in, such as the need to adopt catchment-based integrated land and water resources management. The result is an engaging and accessible case for why water deserves greater attention.
It is easy and engaging to read, and shows us why water is important to individuals and to societies. It is an important book that should really be read by everyone, especially those studying the environment.
