    Monitoreo de los avances en desarrollo urbano: Análisis de los catastros de áreas verdes urbanas en el área metropolitana de Santiago, Chile
    (2019) Reyes Paecke, Sonia; De La Barrera Melgarejo, Francisco; CEDEUS (Chile)
    Advances in urban development goals can be measured through indicator systems. The Chilean National Council for Urban Development (CNDU) has proposed a set of indicators to monitor the progress of Chilean cities towards the goals proposed by the National Urban Development Policy, incoporating issues associated to urban green spaces (UGS) in two areas of evaluation: Access to urban amenities, and urban environmental quality. This article aims to contribute to the analysis of the processes of information collection, data processing and construction of updated indicators of urban development in Chile by identifing the challenges posed by the implementation of a complex system of urban development monitoring. The study focuses on identifying, analyzing and comparing the UGS cadastres of the AMS generated by public institutions, to assess whether they can feed evidence-based design processes for public policy, and the development of a monitoring system of the advances in urban development. Analysis is based on the UGS cadastres carried out in the Metropolitan Area of Santiago between 1992 and 2016 by identifying the responsible institutions, the sources of information and the data obtaining and validating methods. Results show that these cadastres are not comparable to each other, as they use different criteria for the UGS identification and classification, different data sources and collection methods. The fragmentation of decision-making regarding UGS generates inconsistent information, hindering the evaluation of public policy results. The effective implementation of the system of indicators proposed by the CNDU will require the generation of a solid, up-to-date and transparent information basis, prepared by relevant institutions, and validated by proper procedures.

    What really matters in green infrastructure for the urban quality of life? Santiago de Chile as a showcase city
    (Springer Cham, 2018) Banzhaf, Ellen; Reyes Paecke, Sonia; De La Barrera Melgarejo, Francisco; CEDEUS (Chile)
    The built, green and social environment express the situation of a city and, to a large extent, indicate the development of the urban area. These components of the urban environment have a strong impact on the quality of life of citizens. Along with the concepts of resource efficiency and resilience in cities, the quality of life forms one of the three pillars on which our research on urban transformations is grounded. We approach the concept of quality of life from the environmental perspective and understand the human well-being as an integral part of the broader concept of quality of life. In this study we focus on green infrastructure (GI) as an indication for quality of life research. Here, we measure the extent to which people can access GI as a service and profit from this infrastructure for health-related and social dimensions (Scottish Executive 2005; Bognar 2005). Rapid urbanisation processes accelerate land-use changes that mostly go along with extensive urban land consumption and involve population developments. Such multi-dimensional changes in urban land use and land-consumption patterns are very dynamic and widely ramified. They can evoke unsustainable structures that entangle social-spatial differentiations which are discussed in the context of urban growth and shrinkage processes (see Haase et al. in this volume, dealing with urban dynamics, Seto et al. 2011; Kabisch and Kuhlicke 2014). As land is a limited and contested resource, it demands for infrastructural provision and, particularly with respect to urban quality of life and a sustainable urban development, for the provision of green infrastructure.
