Due to rapid urbanization in developing world, city administrators and urban planners are challenged with problems in delivering basic services like green space, sanitation, water supply, transportation, and primary health center. The urban green spaces’ coverage is not adequate to meet people’s needs due to population pressure, expansion of industry, and construction in the process of urbanization (Cetin 2015a, b, c). Urban planners have to visualize such growth during planning, policy, and decision-making. Impulsive construction of unplanned informal houses in and outside the administrative boundaries of towns and cities is common in developing countries. These insightful changes cause a change in land use type which makes urban planning foreseeable (Zewdu 2011). Urban planning does not only cover matters of the built environment such as housing and transportation network, but also the integration of green spaces into the physical urban landscape. The main indicators of planned urbanization expecting physical and socioeconomic development in terms of the suitable areas for health, where bioclimatic comfort arises as one of the most significant factors (Cetin 2015a, b, c). The bioclimatic comfort situations can be established with the design criteria of landscape architecture and planning (Cetin et al. 2016). In recent years, Addis Ababa and its surroundings have observed unprecedented land degradation as a consequence of deforestation for firewood supply and human settlement. Big tracts of the city’s vegetation area are transformed to permanent structures at a rate of 6.65 km2 /year (Tamiru et al. 2005). About 10,000 ha of land initially reserved for green spaces have been allocated for other uses (Tadesse 2010). Over the years, Addis Ababa witnessed ecosystem degradation and vegetation cover is estimated at 14.6% (AAEPA 2005). In the city, 382 ha of riparian area is being cultivated by vegetable growing farmers, which cover up to 7.1% of the city’s vegetable demand (Azeb 2007). Land suitability analysis is the process to determine whether the land resource is appropriate for some specific uses and to determine the suitability level by considering different factors such as LULC (land use and land cover) type, landscape, and road infrastructure (Manlun 2003). Suitability analysis of different LULC patterns and dynamics is important to determine the most desirable site for future development. Identifying appropriate suitability parameters are the foundation of construction of suitability analysis. Green spaces are land uses that are covered with natural or man-made vegetation in the built-up areas and planning areas (Manlun 2003). The meaning of the green space system has also been continuously emerging with the development of city theory, which mainly encompasses horticultural, ecological, and spatial meanings. GIS has the main role in land-use suitability analysis for green space. In the tourism sector also, maps have vital role to protect natural and cultural value in terms of time and cost efficiency and deliver very accurate and up-to-date data (Cetin 2015a, b, c).
