City Comparisons Working Group

With the merit of nine UREx cities in the US and Latin America, the CCWG is a collaborative research structure to coordinate data acquisition and develop comparative research projects across network cities. The CCWG has focused on fostering improved communication and coordination of cross-city research through city updates in the WG meetings and served as a platform for task forces (TFs) for carrying out specific research goals.


Located in the Sonoran Desert, Phoenix, home for 1.6 million residents, is the fifth largest city and one of the fastest growing cities in the US, with the second greatest population in the Southwest. It receives just 8 inches of rain per year, making water scarcity a major concern for many local stakeholders.
