Some potentially significant revelations about the impacts of irrigation used to make public spaces greener and cooler — especially in hotter locales such as the Phoenix area — have been discovered by hydrologist Enrique Vivoni, a professor in the Fulton Schools and the School of Earth and Space Exploration. Aided by graduate students   Mercedes Kindler, Zhaocheng and Eli Pérez-Ruiz, Vivoni used an array of sensing technologies to measure the effects of irrigating one of Phoenix’s urban golf courses. Their year-long study showed a connection between the evaporation of water on the course and the resulting amounts of carbon dioxide emissions, which could contribute to global warming. The story is also reported in Science Daily and Phys.Org.
