The WRRC is pleased to announce the publication of our 2018 Arroyo, "Water and Irrigated Agriculture in Arizona." This Arroyo contains a brief, yet comprehensive history of Arizona's irrigated agriculture, from early indigenous practices to the present, and describes our state's nationally-renowned centers of irrigated agriculture. There are discussions of issues relating to water use by irrigated agriculture, the legal and regulatory context, water challenges, and water efficiency and conservation. It concludes with a look toward future opportunities. Written by the 2017 WRRC Summer Writing Intern, Tim Lahmers, and WRRC Assistant Director, Susanna Eden, this publication is an accessible introduction to the subject and should serve as a handy reference.
