    Urban expansion is a global phenomenon rapidly transforming the earth's land surface, causing negative social and environmental impacts. Analysing its spatial patterns and underlying factors is crucial to promoting sustainable urban forms, especially in developing countries experiencing further increases in expansion. This study quantifies and explores the spatial pattern of the Metropolitan Region of Santiago (Chile) between 1997 and 2013, correlating it with explanatory factors at the municipal level using land cover maps and a Moran Index. The results reveal an urban expansion of 124 %, mainly towards rural and peri-urban municipalities, concentrated in the north and south of the region. The bivariate analysis highlights a positive correlation between factors such as population growth rate, household income, slope, and urban regulations with urban expansion, concentrated in rural-peri-urban areas. On the other hand, the urban area defined by the Santiago Metropolitan Regulatory Plan (PRMS) and population density negatively correlates with urban expansion. The study suggests that the city expanded into municipalities outside the urban area defined by the PRMS, and urban regulations promoted expansion into agricultural and public land. This research has important practical significance for understanding the spatial patterns of urban expansion and its drivers. The study has practical significance in understanding the spatial patterns and their drivers, highlighting priority areas that require urban policy intervention to promote sustainable urban forms.

    Urban Vitality Conditions and Neighborhood Satisfaction in a Latin American City: The Case of Santiago de Chile
    (ASCE-AMER SOC CIVIL ENGINEERS, 2023) Madrid-Solorza, Stephanie; Marquet, Oriol; Fuentes Arce, Luis Alejandro; Miralles-Guasch, Carme; CEDEUS (Chile)
    Urban vitality and neighborhood satisfaction are areas of great interest within the field of urban studies, as a measure of the attractiveness of a city and as an evaluation that residents make of their living environments. Using survey and geospatial data from the Longitudinal Social Study of Chile (2019) and the JANE Index (2021), this study performs regression analysis to examine the relationship between urban vitality and neighborhood satisfaction. Through a set of variables that evaluate the neighborhood such as safety, connectivity, green and recreational areas, cleanliness and beauty, proximity to the main activity, and proximity to commercial areas, we analyze the relationship with six conditions for urban vitality. These conditions are features objectively measured from the built environment, which provide information about concentration of people and buildings, diversity in land use, contact opportunity provided by the urban fabric, presence of old buildings, accessibility to the public transport, and the distance to large infrastructures that act as border vacuums for people. The results show that most conditions for urban vitality are significant predictors of neighborhood satisfaction. Not all components of urban vitality, however, are positively associated with higher neighborhood satisfaction, as attributes such as concentration and satisfaction with green and recreational areas in the neighborhood are in fact negatively correlated. Conclusions show the importance of including subjective factors in projects meant to transform the built environment in search of increased vitality.
