| dc.description.abstract | Unplanned urbanization threatens environmental sustainability, and Addis Ababa is straining its ecosystem, causing a mismatch between ecosystem service (ES) supply and demand. In essence, this study investigates Addis Ababa’s urban street tree planning and management practice from a resilience perspective while focusing on their ecosystem service supply and demand, disservice, as well as challenges. The research is a descriptive and exploratory study that employs quantitative and qualitative methods. Site observation, key-informant interviews, and questionnaire surveys were employed for data collection. Using ES Cascade model as a framework, the research performed thematic, descriptive, correlation, and apparent urgency analysis based on expert and user perception. The resilience assessment of street trees indicated a lack of functional redundancy and species richness with Churchill Road having the relatively highest Shannon diversity (1.89) and equability (0.29), while Meskel Square to Lancha showed the lowest values (0.26 and 0.04, respectively). Besides, connectivity concerns with trees in various street corridors, concerns with stakeholder participation, and limited adaptive capacity were found. Regarding zone-based ES supply and demand quantification, species diversity (2.67 periphery, 2.29 intermediate), followed by aesthetics (2.09 periphery, 1.72 intermediate), storm water management (1.93 intermediate, 1.72 periphery), and local climate regulation (1.34 intermediate) revealed a gap that requires apparent urgency. Results also highlight a high incidence of ecosystem disservices associated with, littering, infrastructural damage, and obstructing use of space. Besides, species selection and space allocation were identified as high-priority planning and design concerns. The prevalence of Grevillea robust a and Phoenix canariensis, species with 51% and 15% respective dominance indicates uniformity in tree species selection, implying the necessity for adaptable solutions that consider urban dynamics. Prioritizing ecosystem services than mere aesthetics, selection of climate-resilient and locally adaptable species, and integrating them with surrounding UGI components were among the recommendations forwarded.
