Brad Stewart Lancaster (born 1967) is an expert in the field of rainwater harvesting and water management, sun & shade harvesting (passive solar design) and community-stewarded native food forestry.[1] He is also a permaculture teacher, designer, consultant, live storyteller[2] and co-founder of the Dunbar/Spring Neighborhood Foresters,[3] and Desert Harvesters,[4] both non-profit organizations.
Lancaster lives on an eighth of an acre (506 m2) in downtown Tucson, Arizona, where rainfall is less than 12 inches (300 mm) per annum. In such arid conditions, Lancaster consistently models that annually catching 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.[5]
Lancaster helped legalize the harvest of street runoff in the city of Tucson, Arizona, with then-illegal water-harvesting curb cuts at his and his brother’s home and demonstration site that made openings in the street curb to enable street runoff to freely irrigate street-side and in-street water-harvesting/traffic-calming landscapes of food-bearing native vegetation.[6] After proving the concept, Brad then worked with the City of Tucson to legalize, enhance, and incentivize the process.[6][7][8]
Lancaster co-created and now co-organizes the Neighborhood Foresters program[3] which since 1996 has coordinated volunteer crews of neighbors to plant and steward over 1,700 native food-bearing trees and thousands of native food-bearing and medicinal understory plantings within or beside water-harvesting earthworks that, combined, harvest over one million gallons (3.7 million liters) of stormwater per year in his neighborhood,[9] while helping and training volunteers from other neighborhoods to lead similar efforts in their neighborhoods.[10]
The Desert Harvesters non-profit organization Brad co-founded teaches the public how to identify, harvest, and process many of the native-plant foods neighbors are planting in their neighborhoods.[11] Desert Harvesters also makes the utilization of native foods easier by organizing community milling events that mill native mesquite pods into nutritious and delicious mesquite flour which is utilized by a growing number of restaurants, breweries, and home kitchens.[11] Brad resigned from Desert Harvesters in the summer of 2020.[12]
He was involved in a 2009 project, acting as a representative for the U.S. State Department on an educational tour in the Middle East.[13]
Lancaster lectures at the ECOSA Institute; the University of Arizona; and Prescott College.[14] He has been a guest speaker at the annual Bioneers Convergence; Green Festival USGBC’s Greenbuild Conference;[15] Texas Natural Building Colloquium;[16] the New Mexico Xeriscape Conference; the Green Festival;[17] the 2009 Water Conservation & Xeriscaping EXPO; the New Mexico Organic Farming Conference;[18] Conference of World Affairs[19] and various Audubon Expeditions.[citation needed]
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,[20] and the Tucson Nature Conservancy water-harvesting demonstration site,[21] the Wallace Desert Garden at the Boyce Thompson Arboretum,[22][23] and the Tumamoc Resilience Garden.[24]
