Backgroundthis study was conducted to explore the ecosystem services of urban forests in Adama city, central Ethiopia. Attempts were made to quantify the carbon storage and sequestration, air pollution removal and hydrological bene ts of urban trees. The urban forest structure and composition of the city was surveyed and analyzed. The i-Tree Eco Model was employed to analyze the ecosystem services based on the current urban forests structure of the city. Resultsthe result revealed that the urban trees of the Adama city stored a total of 116,000 tons of carbon. The tree species identi ed with higher CO 2 sequestration per year were Melia azedarach (15%), Eucalyptusglobulus (8%), Carica papaya (7%), and Delonix regia (6%). In addition, 22%, 12%, 10% and 4% of carbon were stored by Eucalyptus globulus, Melia azedarach, Carica papaya and Delonix regia tree species respectively. Moreover, trees and shrubs species in the city removed about 188 thousand tons of air pollutants caused by O 3 , CO, NO 2 , PM2.5 and SO 2 per year. In Adama, 35% of the urban trees' volatile organic compaound emissions were from Eucalyptus cinerea and Eucalyptus globulus. The monetary value of Adama urban forest in terms of carbon storage, carbon sequestration, and pollution removal was estimated to 43,781, 3,121 yr − 1 and 320,915,596 USD yr − 1 , respectively. Conclusionsit was concluded that signi cant quantity of CO 2 and air pollutants were found being removed by the exotic tree and shrub species. However, every plant species found in the city does not mean ecologically important due their VOC emitting nature. Thus, the results of the study are valuable in increasing the awareness of the decision making bodies, the public and any stakeholders of the eco-bene ts of urban trees in the mitigation of climate changes.

Background: Energy plays an indispensable role in social, and economic development. It is primarily obtained from biomass and converted to required energy using traditional stoves in most developing countries. Currently, the market is dominated by different shapes and sizes of locally produced cooking stoves. Their impact on fuel-saving, and emission reduction, however, has not been exhaustively investigated. Objective and Method: Hence, the objective of this study is to test the fuel efficiency and emission reduction potential of locally produced charcoal stoves. Accordingly, four charcoal stoves and three plant species that are commonly used were collected for conducting laboratory tests following a controlled cooking test. Results: The overall findings revealed that about 62.69% of the respondents use locally produced charcoal stoves compared to the traditional metal stoves (37.31%). However, individual stove-wise analysis indicates that traditional metal stoves are majorly used stove type followed by Lakech (29.36%) and Mirchaye (13.46%) stoves. Overall, a traditional metal stove consumes a huge amount of fuel (0.23ton/year) which is around 0.0046ha of forest and is responsible for the emission of 77.07ton of CO 2 e per year whereas the mean consumption of improved stoves is 0.16ton/year which is about 0.0032ha of forest and emits 13.69tons of CO 2 e per year. Furthermore, these differences were among improved stoves. Accordingly, the highest annual greenhouse gas emission was recorded by Mirchaye stove (14.64ton of CO 2 e) followed by lakech, and kib stoves 13.69, and 12.74ton CO 2 e respectively. The types of wood used for charcoal preparation, in addition to stoves types, also have an impact on the amount of fuel consumed and pollutants emitted. Conclusions: Generally improved stoves significantly contribute to reducing emission and fuel consumption which in turn reduces the impact on forest resources, human health, and global warming of the energy sector. Hence, this finding discloses the distribution of these improved stoves for local communities by government and concerned stakeholders to assure affordable and clean energy for all and reducing pressure on forest and human health.
