Abstract
BackgroundUrban green spaces are important components, contributing in different ways to the quality of human well-being. In the planning and management of urban centres, attention to the appropriate site selection of urban green spaces with regard to the importance that these spaces have from the perspectives of ecology, socioeconomic, mentality, etc., is an inevitable requirement. In present decades, land suitability mapping methods and GIS have been used to support urban green space planners in developed countries; however, its application and practices are limited in developing countries, like Ethiopia. Therefore, the aim of this study has to select potential sites for green spaces in Sululta town that assist an effective planning process of green areas in a sustainable way.MethodsIn this study, GIS-based Multi-criteria analysis (MCA) has been adopted to select suitable sites for urban green spaces. Existing land use, proximity to settlement, road and water body, population density, land ownership, topography, and scenic attractiveness were recognized as the key factor affecting urban green land suitability.ResultsThe results showed that 13.6%, 34%, 28%, and 18.9% of the study area are highly suitable, suitable, moderately suitable, and poorly suitable, respectively, for urban green spaces development. Furthermore, out of the total area of the study town 5.5% of the landmass is not suitable for urban green spaces development.ConclusionsTherefore, the application of GIS-based MCA has provided an effective methodology to solve a complex decisional problem in urban green spaces site selection in the study town and urban planning all over the country.
Highlights
With more than 50 % of the global population living in urban areas, the world has experienced unprecedented urban growth in recent decades (Wu 2014)
Urban green spaces are of crucial importance, especially in an urbanized world, as they are the key providers of ecosystem services and improve the quality of life of urban residents
Description of the study area Sululta town is located in Sululta district of the previous North Shewa administrative zone of Oromia region, currently under Oromia special zone surrounding Finfinne
Summary
With more than 50 % of the global population living in urban areas, the world has experienced unprecedented urban growth in recent decades (Wu 2014). The global urban population is projected to be 6.3 billion by 2050, almost double the global population of 3.5 billion urban dwellers in 2010 (SCBD 2012) This rapid urbanization has posed greater pressure on natural resources and the. By increasing water infiltration, it promotes the regulation of ecosystem services (Haase and Nuissl 2007; Pauleit and Duhme 2000) and has positive impacts on microclimate regulation (Gill et al 2000; Hamada and Ohta 2010). The aim of this study has to select potential sites for green spaces in Sululta town that assist an effective planning process of green areas in a sustainable way
