Ecosystem services and urban heat riskscape moderation: water, green spaces, and social inequality in Phoenix, USA

摘要: Urban ecosystems are subjected to high temperatures—extreme heat events, chronically hot weather, or both—through interactions between local and global climate processes. vegetation may provide a cooling ecosystem service, although many knowledge gaps exist in the biophysical social dynamics of using this service reduce extremes. To better understand patterns urban vegetated cooling, potential water requirements supply these services, differential access services residential neighborhoods, we evaluated three decades (1970–2000) land surface characteristics segregation by income Phoenix, Arizona, USA metropolitan region. We developed an trade-offs approach assess riskscape, defined as spatial variation risk exposure human vulnerability extreme heat. In region, provided nearly 25°C compared bare soil on low-humidity summer days; ma...
