Maximize your water harvesting potential with efficient,
cost-effective earthworks In the face of drought and
desertification, well-designed, water harvesting earthworks such as
swales, ponds, and dams are the most effective way to channel water
into productive use. The result can be increased food production,
higher groundwater levels, reduced irrigation needs, and enhanced
ecosystem resilience. Yet, due to a lack of knowledge, designers,
and landowners often build earthworks that are costly,
inappropriately sized and sited, or even dangerous. The
Permaculture Earthworks Handbook is the first dedicated, detailed
guide to the proper design and construction of water harvesting
earthworks. It covers the function, design, and construction
methods for nine main types of water harvesting earthworks across a
full range of climates. Coverage includes: Swales, ponds, dams,
hugelkultur, net-and-pan systems, spate irrigation, and more Cost
versus benefit of different earthworks Assessing site needs and
suitability Soil types and hydrology Designing for maximum
efficiency and lowest cost Risk assessment and safe construction
Stacking functions and integrating earthworks into a design This
practical handbook is the essential resource for permaculture
designers, teachers and students, landowners, farmers,
homesteaders, landscape architects, and others involved in
maximizing the water harvesting potential of any landscape at the
lowest cost and impact. Douglas Barnes is a permaculture designer
trained in Australia by Bill Mollison and Geoff Lawton. He has
designed and built earthworks in North America, Japan, and Andra
Pradesh, India. He lives in Tweed, Ontario in a passive solar house
he designed and built, and he blogs at permaculturerelections.com.
