Assessing Air Quality Improvement as a Regulating Ecosystem Service in the Ege University Housing Campus
Abstract
Urban green areas provide many valuable ecosystem
services such as regulating storm water infiltration, improving air quality,
reducing urban heat island effects, provisioning food and habitats for many
species, providing recreation and nature education for the city dwellers.
Housing campus of Ege University is one of the largest and the most intact
urban green patches in the Bornova district. This study aimed to answer the
research question that is at what level air quality improvement as a regulating
ecosystem service has been provided by the canopy cover of the Ege University
housing campus? For this purpose, I-tree canopy tool was used to analyze the
removal of atmospheric air pollutants, and carbon sequestrated and stored by
canopy cover of the housing campus. The results revealed that tree and shrub
canopy covers 48.3 % of the campus. While about 321.57 tons of Carbon Dioxide
was sequestered annually, 8107.86 tons of Carbon Dioxide was stored by plants. In
addition, it was calculated that these plants removed about 28.70 kg of Carbon
Monoxide (CO), 143.85 kg of Nitrogen Dioxide (NO2), 1.58 tons of Ozone (O3), 90.6 kg of Sulfur Dioxide (SO2),
69.61 kg PM2.5 and 479.90 kg PM10 particulate
matter per year.
