The result can be increased food production, higher groundwater levels, reduced irrigation needs, and enhanced ecosystem resilience.\u003c\/p\u003e\u003cp\u003eYet, due to a lack of knowledge, designers, and landowners often build earthworks that are costly, inappropriately sized and sited, or even dangerous.\u0026gt;\u003cem\u003eThe Permaculture Earthworks Handbook \u003c\/em\u003eis the first dedicated, detailed guide to the proper design and construction of water harvesting earthworks.
