    Percepción de valores biofílicos en el Humedal Rocuant andalién, área metropolitana de Concepción, Chile
    (Universidad del Bío Bío, 2024) Rojas Quezada, Carolina Alejandra; Villagra, Paula; Jorquera, Felipe; CEDEUS (Chile)
    Este estudio analiza la percepción de valores biofílicos en el humedal Rocuant-Andalién, ubicado en el área metropolitana de Concepción, Chile y examina cómo estas percepciones varían según las tipologías de barrios. El objetivo principal es comprender cómo las diferentes características urbanísticas y sociodemográficas influyen en la valoración de este espacio natural. Para ello, se aplicó un cuestionario georreferenciado a 326 residentes de distintas tipologías de barrios, en el que se evaluó nueve tipos de valores biofílicos (utilitarista, naturalista, ecológico-científico, estético, simbólico, humanista, moralista, dominionista y negativista). Se utilizó un enfoque de Sistemas de Información Geográfica de Participación Pública (PPGIS) y el análisis de hot spot para identificar clústeres de percepción. Los resultados revelaron que las percepciones del humedal varían significativamente según la tipología de barrio, destacándose una mayor valoración de los valores utilitarios y estéticos en áreas de baja densidad. Se identificaron hotspots que indican áreas con alta valoración de ciertos valores biofílicos. La integración de PPGIS y los valores biofílicos demuestra cómo los patrones espaciales influyen en la percepción de los humedales urbanos. Los resultados sugieren que mejorar la infraestructura y la accesibilidad podría fortalecer la conexión de los residentes con estos espacios naturales. Los hallazgos subrayan la importancia de desarrollar políticas de conservación y planificación urbana que sean inclusivas y efectivas, para promover una percepción y gestión más favorable de los humedales urbanos

    Spatial interactions between perceived biophilic values and neighborhood typologies in urban wetlands
    (2024) Villagra, Paula; Rojas Quezada, Carolina Alejandra; Rojas, Octavio; Alves, Susana; CEDEUS (Chile)
    Wetlands provide a wide range of ecosystem services; however, little is known about their perception value or use for improving urban planning and wetland management. This study explores the perception values towards the Los Batros Wetland in Chile, by inhabitants from different neighborhood typologies. A sample of 457 responses evaluated the wetland by applying the Kellert framework of 9 biophilic values using a Public Participation Geographic Information Systems (PPGIS) approach. A spatial autocorrelation analysis with hotspot revealed that the spatial distribution of biophilic values varies by neighborhood typology. Subsequent ANOVA and T-test suggest that such distribution is affected by perceived accessibility and visitation purposes, and is influenced by socio-demographic aspects that vary among neighborhood typology. Inhabitants of the garden city typology located next to the wetland area, whose residents have higher education and income levels and who have easy and moderate access to the wetland, agreed with a diverse type of biophilic values. In the garden city, the ecologistic-scientific value has the higher spatial concentration. In the condominium typology, with similar education and income levels and accessibility, but situated far from the wetland, there was less agreement with biophilic values, and these were more dispersed, i.e. biophilic values are less representative. In this case, the aesthetic value prevails over others. At the north area of the neighborhood unit, where residents had lower education and income levels along with moderate to difficult physical access to the wetland, but they developed horticultural activities alongside the wetland, inhabitants agree with various biophilic values, highlighting its symbolic value. Conversely, biophilic values of people in the favela were not in agreement nor disagreement, regardless they have similar physical access and distance to the wetland as residents in the condominium typology, but have the lowest income and education level. Findings suggest that effective wetlands management requires appreciation of the clusters of values assigned to wetland environments, which in this case relate to neighborhood typologies. These clusters should be considered when planning to restore, protect, and improve urban wetlands.
