Book Description
Qanats are ubiquitous, yet unseen, and a clever way to create streams where none exist in nature. For 3,000 years, they have made life possible in impossible places and still sustain life and livelihoods in many countries today. After 30 years of field research, Dale Lightfoot provides the first comprehensive study of the qanat and sheds new light on their unique locations and distribution, their origins and history, their ecology, current status and use. Qanats are remarkably engineered underground aqueducts, using gravity to bring water to villages and towns where reliable flowing surface water is scarce or absent. Although an ancient technology, more than 46,000 of them still flow around the world today, with their sustainable nature making them a focus of renewed interest. Richly illustrated with images and a series of original maps, this is the most complete record to date of the locations and distribution of qanats worldwide, including examples from the Middle East, North Africa, Europe, Central Asia, China, India, Mexico and South America.

Book Description
Markets for Water: Potential and Performance dispels many of the myths surrounding water markets and gives readers a comprehensive picture of the way that markets have developed in different parts of the world. It is possible, for example, for a water market to fail, and for the transaction costs in water markets to be excessive. Too often water trading is banned because the water resources have been developed with public funds and the water agencies do not want to lose control over water. There is also a concern that poor farmers or households will be disadvantaged by water trading. These concerns about public resources and the poor are not very different from those that have been voiced in the past about land sales. The problem is that in many cases the poor already have limited access to resources, but this limit is not due to water trading. In fact, water trading is likely to expand the access to water for many small-scale farmers. Markets for Water: Potential and Performance provides an analytical framework for water market establishment. It develops the necessary conditions for water markets and illustrates how they can improve both water management and economic efficiency. Finally, the book gives readers an up-to-date picture of what we have learned about water markets in a wide range of countries, from the US to Chile and India.
