摘要

Urban green spaces (UGS) have an important role to play in improving public health by enhancing atmospheric quality, reducing the urban heat island effects, and offering free spaces for physical activity to improve mental health Oosterbroek (Urban For. Urban Green 86:128023, 2023), Chen (Land 10:1367, 2021). In cities such as Rabat, which is known for hosting many emblematic urban greening and historical gardens, the preservation and expansion of green spaces is essential to assure an equitable distribution of these qualitative spaces, ensuring both environmental sustainability and overall public health. Although there is an abundant number of green spaces within the city, spatial inequalities between districts persist, leading to severe environmental degradation, particularly in densely populated areas. As green spaces are considered as the key elements in promoting healthier urban environments, this study uses geospatial data analysis based on satellite imagery (Sentinel 2A) to assess the availability, distribution, and health of vegetation covers among the five administrative districts of Rabat. Satellite imagery, particularly high-resolution data from Sentinel A2, in combination with AI techniques such as deep learning for geospatial classification, allows for a precise assessment of urban green space (UGS) quality. This research integrates advanced spatial analysis with environmental data to identify key areas where green areas can be expanded or improved to better support urban health outcomes by mainly using primary geospatial data of four selected vegetation indices (NDVI, EVI, VARI, and SAVI) to provide a comprehensive assessment of Rabat's urban green spaces. The results of this research explore the opportunities of using the geospatial technologies for informed urban planning, especially in the Moroccan context, in the case of Rabat. The outcome presents actionable strategies for policymakers to increase the quality and performance of urban greening to help promote environmental resilience and improve overall urban health conditions in urban environments.
