IDE’s latest publication was officially launched on March 18 at the world’s largest water event, World Water Forum 2009 in Istanbul, just in time for UN World Water Day on Sunday, March 22.

The focus of this year’s WWD observance is transboundary waters and water sharing opportunities.

IDE’s book, researched and written by Monique Mikhail and Bob Yoder, provides a comprehensive study on the practical implementation of multiple-use water services (or MUS) in Nepal and India.

What is MUS? Basically it’s a concept for low-cost water sharing systems that allow poor rural communities to access clean water for domestic needs and agricultural needs from the same source. MUS used in conjunction with IDE’s micro-irrigation systems allows for production of income-generating, high value crops using half the water that traditional farming methods use.

The book outlines clear ground rules for cooperation on implementing a gravity-fed community system design in the middle hills of Nepal, and discusses the legal, political, financial and institutional barriers and opportunities to scaling up larger MUS systems in India.

If you’re interested in learning more, you can download a PDF copy of the book, “Multiple-Use Water Service Implementation in Nepal and India” here (8MB PDF).
