    Hydro-morphological characteristics and recent changes of a nearly pristine river system in Chilean Patagonia: The Exploradores river network
    (PERGAMON-ELSEVIER SCIENCE LTD, 2020) Banales Seguel, Camila; Salazar, Alejandro; Mao, Luca
    Fluvial systems provide multiple life-supporting functions, but their values are affected by a range of anthro-pogenic disturbances. Hydromorphology is used as a conceptual framework for assessing the status of fluvial systems and design river restoration strategies but is rarely applied to nearly pristine environments. This paper presents one of the first assessments of river characteristics and changes in the Aysen Region, an area in southern Chilean Patagonia. The analysis of multitemporal satellite images allowed to define key patterns related to river morphology of the Exploradores river network. The Exploradores basin experienced only limited and recent human disturbances, and fluvial changes are related almost only to natural climatic or geomorphological processes. The river experienced moderate reduction of active channel width and braiding index over the past 70 years. The basin represents a suitable site to study fluvial processes and dynamics in nearly reference conditions, and changes due to the likely increase of human activities and disturbances in the near future.

    Narrating school vulnerability: Performativity, space, and territory
    (Universidad Católica Silva Henríquez, 2013) Infante Jaras, Marta Del Rosario; Matus, Claudia; Paulsen, Abraham; Salazar, Alejandro; Vizcarra, Ruby
    In this article we explore the production, reproduction, and circulation of discourses about school vulnerability through students' narratives in Chile. Our purpose is to show that "vulnerability" does exist prior to its regulatory and production system.

    The distance to market effect on rural poverty in the Metropolitan Region of Santiago
    (PONTIFICIA UNIV CATOLICA CHILE, INST ESTUDIOS URBANOS TERRITORIALES, 2013) Perez, Rodrigo; Salazar, Alejandro; Foster, William; Osses, Pablo
    The national poverty headcount in Chile has declined considerably since 1990. In 2006, rural poverty rate fell below that of urban areas, due in part to population mobility. Rural areas, however, are still characterized by low educational levels and incomes, explained, in part, by low population density, remoteness to services, and limited access to markets for rural-produced products. This study finds that distance (measured as travel time) of rural populations to urban areas is associated with the incidence of poverty in rural communities after controlling for other factors. Using an econometric model based on geographical and socioeconomic information of the Metropolitan Region of Santiago, the study finds that poverty levels in census tracts increase with distance to Santiago, and, for a given distance, access to transportation reduces poverty, through a mitigation of the distance effect.

    Urban restructuring of globalized territories: A charaterization of the organic growth of the cities of Chiloe, 1979-2008
    (PONTIFICA UNIV CATOLICA CHILE, INST GEOGRAFIA, 2013) Barton, Jonathan; Pozo, Ricardo; Roman, Alvaro; Salazar, Alejandro; CEDEUS (Chile)
    Chiloe archipelago has experienced profound socio-spatial changes since the early 1980s. The localization and progressive consolidation of the salmon industry changed the velocity and composition of the urbanization process in the province, generating new forms of spatial occupation. This can be seen in a new urban typology characterized by nine forms of occupation. This typology emerges from an analysis of the morphological evolution of five cities using GIS. The article concludes that the insertion of small and medium size cities in circuits, or networks of global capital takes place at a high velocity, leaving urban planning, a public function, behind. Consequently, urban planning ends up as an instrument of recognition of organic urban growth and not of regulation and growth orientation. This situation of differentiated velocities generates disequilibria that negatively

    We discuss the design, implementation, and results of a collaborative process designed to elucidate the complex systems that drive food behaviors, transport, and health in Latin American cities and to build capacity for systems thinking and community-based system dynamics (CBSD) methods among diverse research team members and stakeholders. During three CB SD workshops, 62 stakeholders from 10 Latin American countries identified 98 variables and a series of feedback loops that shape food behaviors, transportation and health, along with 52 policy levers. Our findings suggest that CBSD can engage local stakeholders, help them view problems through the lens of complex systems and use their insights to prioritize research efforts and identify novel solutions that consider mechanisms of complexity.
