Urban Green Space Composition and Configuration in Functional Land Use Areas in Addis Ababa, Ethiopia, and Their Relationship with Urban Form

Abstract

This study aimed to assess the compositions and configurations of the urban green spaces (UGS) in urban functional land use areas in Addis Ababa, Ethiopia. The UGS data were extracted from Landsat 8 (OLI/TIRS) imagery and examined along with ancillary data. The results showed that the high-density mixed residence, medium-density mixed residence, and low-density mixed residence areas contained 16.7%, 8.7%, and 42.6% of the UGS, respectively, and together occupied 67.5% of the total UGS in the study area. Manufacturing and storage, social services, transport, administration, municipal function, and commercial areas contained 11.6%, 8.2%, 6.6%, 3.3%, 1.3%, and 1% of the UGS, respectively, together account for only 32% of the total UGS, indicating that two-third of the UGS were found in residential areas. Further, the results showed that 86.2% of individual UGS measured less than 3000 m2, while 13.8% were greater than 3000 m2, demonstrating a high level of fragmentation. The results also showed that there were strong correlations among landscape metrics, while the relationship between urban form and landscape metrics was moderate. Finally, more studies need to be conducted on the spatial pattern characteristics of UGS using very high-resolution (VHR) images. Additionally, future urban planning, design, and management need to be guided by an understanding of the composition and configuration of the UGS.

Characterization of Visitors’ Perception of Landscape Heterogeneity in Urban Green Spaces

“…We found that landscape configurational heterogeneity is associated with perception. In a decision-making context in which stakeholders would like to increase landscape heterogeneity for improving perception, particular attention must be paid to the impacts on landscape composition, another important structuring element of UGS [61]. The importance of balancing configuration and compositional elements is a key ecological concern to promote biodiversity [29], particularly in UGS, and thus visitor well-being [62].…”

Implementation and Evaluation of Urban Green Space Supply for Debre Berhan Town, Ethiopia

“…5d). Likewise a study by Woldesemayat and Genovese (2021) a rmed that inner parts of the urban centers in developing countries have low supply of UGS, which increases towards the peripheries.…”

“…Urban green space (UGS) refers to part of urban land covered with vegetation (Rahimi, 2020), and is recognized solution for creating smart and resident friendly urban centers (Tan et al, 2013;Demuzere et al, 2014;Wolch et al, 2014;Jennings et al, 2016;Daniels et al, 2018;Woldesemayat and Genovese, 2021). UGS has multitude of social, economic, ecological, and planning bene ts (Attwell, 2000;Kaczynski and Henderson, 2008;Baycan-Levent and Nijkamp, 2009;Sadeghian and Vardanyan, 2013;Kabisch et al, 2016;Pulighe et al, 2016;Anguluri and Narayanan, 2017).…”

“…Geospatial data and analysis techniques are very effective in urban greenery planning, their availability assessment, and evaluation. Many studies demonstrated the effectiveness of geospatial techniques for urban green space analysis and mapping (Hashim et al, 2019;Elderbrock et al, 2020;Woldesemayat and Genovese, 2021;Kumakoshi et al, 2020;Le Texier et al, 2018). Now a days Debre Berahn town is experiencing rapid growth of industrialization due to its proximity to Addis Ababa and its conducive climatic condition.…”

Sustainable Urban Green Infrastructure Development and Management System in Rapidly Urbanized Cities of Ethiopia

“…Studies have shown that a well-developed and managed urban green infrastructure contributes significantly to urban sustainability by providing significant benefits in the areas of social, economic, and environmental concerns [20,73,74]. In both developed and developing countries, urban green infrastructure can provide passive and active recreation and help to meet a community's leisure needs by providing places for playing, sport, recreation, special events, and other leisure activities [75,76].…”
