Ricardo Aguirre, PE, D.WRE, AP
Director of Drylands Alliance for Addressing Water Needs
Ricardo Aguirre is descended from one of the pioneer ranching families in the state of Arizona. After growing up on a cattle ranch and cotton farm in the state, he studied civil engineering at the University of Arizona, going on to receive a master’s degree in civil engineering (water resources and hydro-systems) from the University of Illinois at Urbana-Champaign. He is a professional civil engineer, licensed to practice in Arizona and Utah.
Ricardo practiced traditional civil engineering for about 15 years, but when he started a family, he knew he wanted to instill the same agrarian values that he grew up with. Knowing he didn’t want to pursue the kind of chemically-supported industrial agriculture responsible for degrading the environment, he turned to various regenerative agricultural practices such as permaculture and Holistic Management. In the course of this journey, he became an Accredited Professional in Holistic Management from the Savory Institute, a certified floodplain manager from the Association of State Floodplain Managers, and a Certified Water Harvesting Design Practitioner from the Water Management Group.
Today, Ricardo is focused on combining his twenty-plus years of experience in engineering with his background in regenerative farming and ranching to integrate natural processes into large-scale engineering projects. The multiple perspectives with which he approaches his work enable Ricardo to quickly define the strengths, weaknesses, opportunities, and threats associated with water resource and land management projects of all sizes. Get in touch with him today to see how he can help you improve the regenerative capacity of your land or come out to the next tour of the DAAWN farm and ranch.
