Abstract
Cities face crucial issues related to urbanization, declining quality of life, inadequate infrastructure, and ecosystem degradation. Those issues have huge impacts on the health and wellbeing of communities. In response, the World Health Organization (WHO) recommend sgranting each person in a city a minimum of 9 m2 of urban green spaces. Many cities face challenges to achieve this requirement due to limited green public areas. In Egypt, due to high urbanization rate and increased densification, some cities, particularly large ones, are struggling to provide a proper share of open spaces per capita. Those cities are under increasing strain as a result of growing populations, resource limitations, and the escalating consequences of climate change. These issues need to be resolved for cities to provide healthy, sustainable living environments. The world’s arguably finite ecosystem resources and the rising demands on their availability have made it clear that more thorough research into natural resources is required. Exploring and promoting urban green spaces in cities could contribute to an improved quality of life (QoL) and ecosystem services (ES). In this respect, “Urban Green Infrastructure” (UGI) responds to such issues by offering opportunities that attempt to preserve values and functions of ecosystems, as well as solutions to support biodiversity and urban healthy environments. This research focuses on green spaces as a main component of UGI in Alexandria, Egypt’s secondlargest city, through the application of the Patch Matrix Model (PMM). Since the 1980s, PMM has been a fundamental principle in landscape ecology, as it describes the horizontal landscape structure in a simple practical way by delineating homogeneous areas and by quantitatively assessing their spatial arrangement and diversity. PMM is adopted to classify and analyze UGI on an urban scale in Alexandria’s Al Montazah district. Using remotely sensed data, Esri Sentinel-2 Land Cover maps, as well as existing local spatial information systems, delineation of existing and potential patches, corridors and matrices is performed. Homogenous areas of open spaces are analyzed in terms of their shape, size, and functions. Linear Corridors in the city are also investigated and the spatial arrangement of the PMM components is developed. Based on the implementation of a highly urbanized district, discussions extend to the potential and limitation of this approach for quantifying urban landscape and performing further spatial analysis processes. The research results confirm the validity of PMM in delineating and providing scenarios for UGI development, and in proposing a tactic plan for city-scale interventions.
