Nature-based Solutions that include green infrastructure planning and design have been identified as one of the key strategies for climate change adaptation in cities (Frantzeskaki et al., 2019). Increasing urbanization with a lack of green infrastructure has made cities vulnerable to the impacts of climate change from urban heat island effect, heat waves, water scarcity, change in precipitation regime, flash floods caused by rainwater, increase in the number of dry days, to name a few (Cheng, 2016; AlKhaled et al., 2020). Planning the green infrastructure system with a holistic approach can increase the resilience of cities in combating the negative effects of climate change in cities and lead to the emergence of cities that are resilient to climate change. The aim of the research is to identify priority areas for maximizing the benefits of ecosystem services provided by green infrastructure and to develop strategies for spatial planning. Phoenix metropolitan area, Arizona, is among the fastest growing cities in the United States. Located in the hot and arid southwestern climate, Phoenix has experienced increased intensity and duration of extreme heat. This urban development increases the pressure on ecological structure and open-green spaces and leads to the emergence of social vulnerability and injustice. The Green Infrastructure Spatial Planning (GISP) model (Meerow and Newell, 2017) was employed to analyze the spatial data (i.e., social, topography, land cover-land use, zoning plan, weather, air pollution, drainage) and prioritize green infrastructure system based on ecosystem services it provides. GIS-based multi-criteria decision-making techniques are used in the model. Six were identified; managing stormwater, reducing social vulnerability, increasing access to green space, reducing the urban heat island effect, improving air quality, and increasing landscape connectivity. The unit of analysis is the US Census Track. Each factor was weighted with AHP, a multicriteria decision-making method, in line with expert opinions, and the correlation between them. Based on the prioritization results, strategies were developed at different scales for multifunctional planning of the green infrastructure system of the city of Phoenix. The empirical data provided by the research help to inform decision-makers for prioritizing the development of planning strategies that take into account the ecological structure in accordance with the natural, cultural, and social structure of the space. The model, which has a f lexible structure in the context of planning, will support the development of participatory and multifunctional green infrastructure policies and strategies in the field of landscape architecture.
