This leads to increased demand for accessible urban green spaces (UGSs). Various efforts have been made in order to address these issues. However, despite the Keywords: abundant scientificliterature available on the accessibility of UGSs in many parts of the world, only a few studies Addis Ababa have been conducted in sub-Saharan Africa and particularly in Ethiopia. The aim of this study is to fill this Ethiopia research gap with an empirical investigation of the accessibility of 23 existing public recreational parks (clas Network analysis sifiedhierarchically in City, Sub-city and Woreda Parks) in Addis Ababa, Ethiopia, by using a GIS based network Public recreational parks Sub-Saharan Africa analysis method at the sub-city level. The study is particularly relevant and urgent as the Addis Ababa City Urban green spaces Council is currently planning to establish 2730 ha of new recreational park area until 2027. The results show that the public recreational parks in Addis Ababa are relatively few in numbers, small in size and cover large service areas. Moreover they are unevenly distributed throughout the city. Six out of ten sub-cities - in which more than 70 % of the inhabitants of Addis Ababa live - have relatively few parks. A wide variation in the accessibility exists for the three park types. Low accessibility was particularly recorded for City and Woreda Parks, and for the outskirts of the city. The proposed plan by the Addis Ababa City Council has the potential to reduce this gap, but its concept to dedicate 89.2 % of the newly established park area as City Parks and only 2% as Woreda Parks does not match with the actual accessibility problems. It is therefore recommended to establish many small size Woreda Parks, which often provide important day-to-day benefits to the nearby residents, instead of few large City Parks. The plan should focus on sub-cities in the South and East of Addis Ababa which are park-deficient, and there especially on areas with ‘poorer’ communities. These sub-cities have less built-up areas, so more space for new parks, but a high current and future demand, mainly due to rapid population growth promoted through mass housing development projects. 1. Introduction (Biernacka and Kronenberg, 2018). In this study, we consider public recreational parks as green spaces reserved primarily for recreational Urban green spaces (UGSs) provide multiple ecosystem services to services to the general public free of charge. The term accessible green humans such as air purification,microclimate modification,mental and spaces has been coined in the early 1990s when the Accessible Natural physical health benefits, social interaction and community integration Green Space Standard (ANGSt) was developed in the UK based on (Maas et al., 2006; Escobedo and Nowak, 2009; Lafortezza et al., 2009; research on the minimum distance residents should travel to reach a Maas et al., 2009). In recent years, UGSs are considered as an indicator natural environment (Natural England, 2010). However, the issue of of the quality of urban life. Their distribution and ease of access are seen accessibility gained more recognition after the United Nations (UN) as key contributors for ecological and social functions of urban envi Sustainable Development Goals (SDG) set a target to provide “universal ronments and for environmental justice (Barbosa et al., 2007; Wendel access to safe, inclusive and accessible, green and public spaces, in et al., 2012; Wolch et al., 2014).
