To Catch the Rain is a book for community members seeking water solutions, as well as students and teachers developing science, environmental studies, sustainable design, international development, engineering, mathematics, practitioners, and DIYers. This book includes project details and images from dozens contributors to the Appropedia Foundation, a non-profit dedicated to "sharing knowledge to build rich, sustainable lives." Up-to-date resource pages on Appropedia support each of the projects and resources in the book for long term follow-up. Some of the projects have been updated periodically online for over a decade! It is just the first of a series of books we are working on for sustainable resources like water and energy and the kindle edition will be free from 01/15-01/18/2020.
