Research Overview & Background
The WaterMAPS™ development team began their research collaboration on water use in urban irrigated landscapes in the late 1990s. Increasing attention was being paid to outdoor water use at that time due to rapid urbanization in the western U.S. and other drought-prone regions of the world, and the need for greater urban water use efficiency. The research community had made progress assessing urban landscape water use through the filter of individual disciplines; e.g., plant science, irrigation technology, conservation behavior, and policy studies. Researchers generally concluded more interdisciplinary and integrated work needed to be done to fully understand how to affect the multi-dimensional challenge (including environmental, technical, biological and human behavioral components) of understanding and influencing urban landscape water use.
The interdisciplinary work conducted by Drs. Joanna Endter-Wada (policy and social science), Roger Kjelgren (urban horticulture and native plants) and Christopher Neale (irrigation engineering and remote sensing) has focused on fulfilling these scientific and applied research needs. They began their joint research effort to provide technical assistance to Utah’s water suppliers seeking to conserve water in irrigated urban landscapes. Working together and with their students and professional staff, the primary contributions of their research collaboration are:
• technical innovations for identifying locations with “capacity to conserve” water applied to urban landscapes and tracking water conservation efforts over time, incorporated into the WaterMAPS™ software;
• research findings on people’s watering behaviors and how those behaviors are shaped by their preferences, knowledge, and experiences as well as by site-specific characteristics of their landscapes (soil properties, plant characteristics, and irrigation systems);
• program and policy recommendations about how to: provide relevant information to help people understand the water needs of their established landscapes and reduce excess water use; broaden the influence of conservation programs; and, promote transitions to greater use of low-water plant material and landscape designs.
