Role of Urban Forests for Carbon Emission Reduction in Addis Ababa:A review

Abstract

Urban forests improve the microclimate and air quality. The objective of this review was to appraise research findings and to summarize the most important literatures on the role of urban forests for carbon emission reduction in Addis Ababa. Total number of identified papers were 11 that studied carbon sequestration potential of urban forests in Addis Ababa and of this church forests (three), public parks (four), botanical garden (one), Mountain forest (Three) and KMU compound included in the review of this paper. The selected research papers used similar allometric equations to calculate carbon stock of the different carbon pools. The mean carbon in the above ground and below ground biomass were 110.84 ± 46.33 t ha -1 and 21.68 ± 9.31 t ha -1 respectively. The mean carbon in dead litter and soil carbon were 6.33±5.72 t ha -1 and 121.02 ± 48 t ha -1 respectively. The variations observed in carbon stocks in the different urban forest types relate to area, density and size of trees available in each site. Urban trees reduce atmospheric carbon dioxide (CO2) through sequestration which is important for climate change mitigation, they are also important for recreational, medicinal value and aesthetic and biodiversity conservation.

Assessment of the Relationships Between Leaf Characteristics with Air Pollutants: A Case Study on Oriental Plane (Platanus orientalisL.) and Caucasian Hackberry (Celtis caucasicaWilld.)

“…Urban forests have a signifi cant value due to their shared relationship with humans and their diverse ecological and environmental functions such as landscape beauty, reduction of pollution and land surface temperature, climate adjustment, oxygen production, atmospheric carbon deposition, and ambient air conditioning (Schwaab et al 2021;Habtamu and Elias 2022). Today, with the increase of greenhouse gases and the occurrence of global warming, there is no doubt that trees, shrubs, and green spaces as sources of carbon dioxide absorption and control of the earth's temperature play an important role in improving living conditions and improving quantitative and qualitative aspects.…”
