This study is a global inventory of successes, delays, and setback in the process of switching from various traditional sources to recycled water for agricultural irrigation. The project used multiple methods to evaluate the impediments and incentives impacting the use of recycled water in agriculture, and how their relevance differed among different stakeholder groups. Analyses were conducted at the project, regional, national, and global scales, and included the perspectives of various stakeholder groups, including water and wastewater utilities, growers, and regulators. The research included a comprehensive review of the literature, interviews with utilities and farmers, review of water utilities’ planning documents, a spatial assessment of irrigated farmlands and wastewater treatment plants, and case studies of projects in California, Florida, Idaho, Colorado, Australia, Israel, and Japan.
