    Polycentrism in Chile: Exploratory measurement for city-systems of regions La Araucania, Los Rios and Los Lagos
    (PONTIFICA UNIV CATOLICA CHILE, INST GEOGRAFIA, 2012) Maturana Miranda, Francisco Ramon; Arenas Vasquez, Federico
    Polycentricity is a concept that has gained strength in recent years as one of the European territorial policy strategic objectives, which aims to promote more balanced and cohesive spaces. Its definition and measurement has generated much debate in the international scientific community, in which Chile has been lagging. This publication aims to define the concept of polycentricity, its main aspects and to propose some improvements in the measurement methods were used. For this purpose, it has been applied a theoretical measurement of the level of polycentricity within three regions of southern Chile: la Araucania, los Rios and los Lagos. The results suggest the existence of a lower middle polycentricity as a whole system and a low level of polycentric in each region.

    Water vulnerabilities mapping: a multi-criteria and multi-scale assessment in central Chile
    (IWA PUBLISHING, 2021) Paegelow, Martin; Quense, Jorge; Peltier, Anne; Henriquez Ruiz, Cristian; Le Goff, Lucie; Arenas Vasquez, Federico; Antoine, Jean Marc; CEDEUS (Chile)
    One of the major challenges that populations have to face is vulnerability to water: lack of water, flooding, pollution, hazard sensitivity and coping capacity. For the reason of economic, social and environmental inequalities, this paper focuses on water-related vulnerabilities in the Metropolitan Region of Santiago (RMS) in Chile. Our main objective is to understand, through mapping, the multiscalar logics of water vulnerability. This study is carried out at two scales: at the regional level (RMS), we proceed with open access municipal statistical data and maps, while at the local level, a more detailed analysis focussing on the Chacabuco Province is based on the same type of data but with either a higher spatial resolution (Census districts) or a spatially more intensive data processing in order to take into account intra-municipal differences. In this way, we put into perspective the discourse developed in the Chilean media and by the inhabitants of Chacabuco Province regarding the province as an environmental 'sacrifice zone' for the RMS. The vulnerability maps are carried out at different scales in a simple and reproducible way by multi-criteria evaluation (MCE). The results confirm the hypothesis of a sacrifice zone and show that high-resolution data and adequate data processing give, on average, lower vulnerability scores than using only statistical data on the municipal level. The results provide a cartographic decision support for stakeholders. Limitations of the study are discussed and required further research pointed out.
