Urban planners should prioritize ridding cities and towns of “shade deserts” to give communities a stronger defense against the levels of heat that are exposing people to serious health risks. Ariane Middel, an associate professor in the School of Computing and Augmented Intelligence, a part of the Fulton Schools, along with ASU research colleagues Jennifer Vanos and V. Kelly Turner, write that providing shade to shield people from the Sun is among the most effective and less costly ways to prevent harm from extreme temperatures, but those measures are frequently not a significant part of urban planning and climate-change mitigation strategies.
