Brad Lancaster
Since 1993, Brad's turned water scarcity into water abundance & run a successful permaculture consulting, design, and education business focused on integrated and sustainable approaches to landscape design, planning, and living. As he lives in the dryland environment, rainwater harvesting has long been one of his specialties and a great passion. Through his business he shares his passions, innovations, and daily adventures that come about from striving to live more sustainably and comfortably in the Sonoran Desert. With his brother, he harvests over 100,000 gallons of rainwater a year on a 1/8-acre urban lot and adjoining right-of-way. This harvested water is turned into living air conditioners of food-bearing shade trees, abundant gardens, and a thriving landscape incorporating wildlife habitat, beauty, edible and medicinal plants, and more. Such sheltering landscapes can cool buildings by up to 20° F (11° C), reduce water and energy bills, and require little more than rainwater to thrive.

Brad is the author of the Rainwater Harvesting for Drylands and Beyond series. It is a three-volume guide on how to conceptualize, design, and implement sustainable water-harvesting systems for your home, landscape, and community.
