This study outlined the first comprehensive assessment of urban morphological characteristics and the impact on temperature regulation services for two African cities: Addis Ababa, Ethiopia and Dar es Salaam, Tanzania. Green structures provide important temperature regulation services through cooling the local environment via evapotranspiration, shading, and re-radiating less heat than built-up surfaces. Urban Morphology Types (UMTs) provide a good framework for assessing ecosystem services and land use planning.
