Abstract

The study of urban green space has become an important topic of research in the last decade. In this study the green area coverage of 11 administrative units of Tirana is evaluated based on the 2015 orthophoto. The total green area and the distribution for administrative units as well as relationships between the amount of green space, suicide, and noise and air pollution over different buffer distances from the monitoring points are evaluated. Over 27% of the area of the city of Tirana is covered by greenery but the distribution is heterogeneous among administrative units. The noise tended to decrease with increasing amount of greenery; however, the trends were not significant. On the other hand, the amount of air pollution decreased significantly with increasing amount of greenery and the strength of the relationship increased with increasing distance from the monitoring points. The relationship between greenery and suicidal rate overall was not significant, except for the most urbanized administrative units; however this based on a limited sample size. The data from this analysis shows trends between the amount of greenery and various health and environmental indicators that could be useful for better planning and management of green spaces in the future, however, more data is needed.
