    Calles para el buen vivir: tres casos chilenos
    (Centro de Desarrollo Urbano Sustentable, 2023) Sagaris, Lake; Echiburu Altamirano, Tomás; Muñoz, Juan Carlos; Valenzuela, Luis; CEDEUS (Chile)
    Medio siglo de experimentación demuestra la efectividad de algunas estrategias para reconquistar las calles locales, para recuperar su uso para caminar, socializar, jugar. Una revisión global, realizada en el marco de una colaboración con el Transport & Health Science Group (Reino Unido), generó más de 20 estrategias. Rescatamos estos aprendizajes a la luz de tres casos en distintas comunas de Santiago de Chile: La Reina, Renca y Bellavista (Providencia). Internacionalmente, una participación ciudadana deliberante y vinculante se ha demostrado como central, pero también es necesario considerar falencias de la institucionalidad chilena, que identificamos al revisar estas experiencias.

    Exploring the correlation between city size and residential segregation: comparing Chilean cities with spatially unbiased indexes
    (2020) Garreton, Matias; Basauri, Agustin; Valenzuela, Luis
    Urban segregation is a widespread phenomenon with profound social implications, and one that presents difficult measurement challenges. Segregation indexes may be affected by scale or zoning biases of the modifiable areal unit problem (MAUP). In this article, we develop a methodology that relies on spatial clustering algorithms to simultaneously cope with both kinds of MAUP biases, and we test it with complete census data for most Chilean cities. We find a robust correlation between segregation and city size, contesting previous claims about the spuriousness of this relationship. We also show that socioeconomic polarization is a widespread phenomenon in Chile and that it is not just a problem of disadvantaged groups' concentration. Based on these results, we suggest that area-based desegregation policies should be generally reinforced, and complemented in big Chilean cities with housing-mix policies. We argue that using spatially unbiased segregation indexes could improve comparative urban studies.
