I bought this instead of Volume 8 to follow along with a course I was taking through Colorado State. On hindsight, I didn't really need the book as what I was getting online was good enough for tests and discussion. However, this doesn't mean the book is bad. Absolutely not, it's packed with lots of useful information, examples, and decisions made in transboundary agreements and where the world is heading toward water resource management. If you want something in-depth, this is it. If you want something a little more generalized because you have an interest but not a master degree's kinda interest, I would look elsewhere or simply study it online at various reputable websites. The Colorado State online course I took has all their lecture videos online for free.
The essays in this book by Peter Gleick and some other analysts spotlight one of the key resource challenges the world faces -- how to address the growing water shortages. These shortages carry major socioeconomic implications. They also threaten to instigate political conflicts within states and across boundary boundaries.
This volume focuses on several facets of the water challenge, including quality, distribution and competition. A separate section examines China's dams, many of which have cross-border implications.
This is a good volume which could have benefited from a stronger structure.
