Brad Stewart Lancaster (born March 15, 1967) is an expert in the field of rainwater harvesting and water management. He is also a permaculture teacher, designer, consultant and co-founder of Desert Harvesters, a non-profit organization.
Lancaster lives on an eighth of 1 acre (0.40 ha) in downtown Tucson, Arizona, where rainfall is less than 12 inches (300 mm) per annum. In such arid conditions, Brad consistently models that catching over 100,000 US gallons (380,000 l; 83,000 imp gal) of rainwater to feed food-bearing shade trees, abundant gardens, and a thriving landscape is a much more viable option than the municipal system of directing it into storm drains and sewer systems.
Lancaster lectures at the ECOSA Institute, the University of Arizona, and Prescott College. He has been a guest speaker at the annual Bioneers Convergence; Green Festival USGBC’s Greenbuild Conference; Texas Natural Building Colloquium; the New Mexico Xeriscape Conference; the Green Festival; the 2009 Water Conservation & Xeriscaping EXPO; the New Mexico Organic Farming Conference and various Audubon Expeditions.
Lancaster has designed integrated water-harvesting and permaculture systems for multiple projects, including the Tucson Audubon Simpson Farm restoration site; the Milagro development; Stone Curves co-housing project; and the Tucson Nature Conservancy water-harvesting demonstration site.
