    Diseño urbano como herramienta para reducir la persepción de inseguridad
    (Centro de Desarrollo Urbano Sustentable, 2020) Navarrete, Pablo; Lunecke, Alejandra; Fuentes, Luis; Trufello, Ricardo; CEDEUS (Chile)
    La inseguridad en el espacio público no solo reduce el bienestar psicológico de las personas, sino también su uso y la participación en la vida de barrio. Por este motivo, diversos programas gubernamentales se han centrado en el rediseño del espacio público. Se propone una metodología para mapear la percepción de inseguridad y medir ex ante el impacto que tendrán las intervenciones de los programas de regeneración urbana en los habitantes, utilizando métodos de interpolación espacial y experimentos aleatorios de control y tratamiento basados en imágenes. Como resultado se identifican zonas de alta concentración de inseguridad, lo que permite seleccionar aquellos proyectos de intervención de mayor impacto mejorando el costo-eficiencia de la inversión pública

    The Construction of a Segregated Metropolis: Urban Segregation and Natural Preexistences in the Metropolitan Area of Concepción
    (Springer Nature Switzerland AG, 2025) Villouta, Daniela; Trufello, Ricardo; Greene Zuniga Margarita; Fernández, Andrea; CEDEUS (Chile)
    Urban segregationSegregation has been the center of discussion in various theories of urban sociology (Ruiz-Tagle, 2016), gaining great importance in recent years. The problem has been mainly addressed from residential location and socioeconomic stratification, although there are other factors that can complement its understanding and representation. Among them, the level of segregationSegregation according to socioeconomic level and its representation in spaceSpace (Trufello et al., North Grande Geography Journal 160:81–131, 2022) play a key role in the construction of an area in the process of metropolitanization. This article seeks to observe the way in which segregationSegregation has been constructed and evolved in the Metropolitan Area of Concepción (AMC) from its representation in spaceSpace. Using a quantitative methodologyMethodology, first, homogeneous areas are constructed regarding territorial segregationSegregation attributes in the AMC from the geolocation of an entropy index and socioeconomic variables. Second, typologies of urban environmentsEnvironment are constructed considering the natural preexistences in the territory. These data are processed through spatial statistics from the regionalizationRegionalization method and its cartographic representationCartographic representation. The results contribute to understanding socio-spatial segregationSegregation from its representation in spaceSpace at the metropolitan level. With this, it is expected to minimize the error of representative samples for the generation of the surveys that will be carried out after this study and for the selection of metropolitan-level case studies.
