An Estimation of Oxygen Release from Green Surfaces in Durres City

Due to urbanization trend in Durres city, distance between city inhabitants and nature is increasing. Urban greenery is one of the methods to bridge this gap between people and nature. The study results were performed with the cooperation of EPER Center, professors and students of Durres “Aleksander Moisiu” University. It was focused in the estimation of O2 release from green surfaces at different areas of Durres city. The results achieved were carried out by field visits, the use of the GIS method and calculations performed based on various standard manuals. According to the results, it was concluded that the total amount of O2 release from green surfaces was 64420 kg/year or 64.4 t /year. It was also calculated that the available green surface for a resident in Durres city is only 1.05 m2 out of required 9 m2 per capita. Based on the needs of the population and the EU standards, this study suggests that the amount of O2 release should be 1.49∙ 108 kg/year or 1.49. 5∙ 105 t/year. The needed costs to be invested to achieve this O2 amount, is about 47 .65 billion ALL. Finally, it can be concluded that the low number of trees in Durres city, requires urgent provisions to improve air, and life quality of Durres citizens.
