Modification of heat-related mortality in an elderly urban population by vegetation (urban green) and proximity to water (urban blue): Evidence from Lisbon, Portugal
Urban populations are highly vulnerable to the adverse effects of heat, with heat-related mortality showing intra-urban variations that are likely due to differences in urban characteristics and socioeconomic status. The objective was to investigate the influence of urban green and urban blue, i.e., urban vegetation and water bodies, on heat-related excess mortality in the elderly above 65 years in Lisbon, Portugal between 1998 and 2008.
