Water Use Efficiency in Urban Food Gardens: Insights from a Systematic Review and Case Study

Urban Farm DB summary

A systematic review of literature from 1975 to 2018 on urban agriculture yield research found that only 5 out of 25 articles actively collected water use data from the perspective of water use efficiency, all from purpose-built experimental gardens. Given the scarcity of literature on urban agriculture water use efficiency and measurement, a case study from South Australia demonstrated the diversity of water pricing, sources, and irrigation methods. Four equations for calculating urban agriculture water use efficiency (WUE) were proposed.
