A Call for Biomonitoring Systems in Latin America and the Caribbean: Considerations for Potentially Toxic Metals/ Metalloids
(Ubiquity Press, 2022) Tamayo-Ortiz, Marcela; Riojas-Rodríguez, Horacio; Téllez-Rojo, Marta M.; Boischio, Ana; Mañay, Nelly; Menezes-Filho, José Antonio; Queirolo, Elena I.; Cortés Arancibia, Sandra Isabel; Kordas, Katarzyna; CEDEUS (Chile)
The Latin America and the Caribbean (LAC) region makes up 8.4% of the world’s population. Human biomonitoring (HBM) programs, which can shed light on populationlevel exposure to environmental contaminants such as toxic metals and thus, improve the health of the populations are inexistent in LAC countries. We call for the creation of HBM programs in the region and identify three viable design options for HBM at the individual level, through national surveys, newborn blood collection, and biobanks. We highlight some of challenges to the implementation of HBM programs, including financial and human resources, technical constrains (laboratory), sample, and data logistics. Finally, we provide the case studies of Brazil, Chile, Mexico, and Uruguay, to illustrate a range of responses to toxic metal exposure in non-occupational populations. Although different in many respects, the individual country responses share two commonalities: 1) academic centers drive the research to raise awareness of governmental entities; 2) reference levels are adapted from international norms rather than arising from the studied populations. Well-designed and sufficiently funded biomonitoring systems need to be established in each country of the LAC region. HBM programs are key to promoting human health by informing the public and contributing to policy processes that establish sustainable environmental controls and health prevention programs.
A greener urban environment: designing green infrastructure interventions to promote citizens’ subjective wellbeing
(Elsevier B.V., 2019) Navarrete-Hernández, Pablo; Laffan, Kate; CEDEUS (Chile); Pontificia Universidad Católica de Chile. Facultad de Arquitectura, Diseño y Estudios Urbanos
Research using subjective wellbeing (SWB) measures finds that the greener an individual's local environment is, the higher the levels of happiness and the lower levels of stress they tend to report experiencing. This literature presents positive associations between existing large-scale green spaces, such as urban parks or squares, and the wellbeing of residents living in close proximity to them. In contrast, in the current work, we present a novel approach which combines SWB measures with photo simulation in order to examine the impact of street-level green infrastructure interventions on the people's perceptions of the SWB associated with urban sites. We tested the approach with the attendees of the 20th Biennale on Architecture and Urbanism in Chile in 2017, exploring the impact of four different types of street-level green interventions. The results indicate that all types of green interventions considered significantly increase the perceived happiness and reduce the perceived stress associated with the sites during short exposures, with varying effect sizes across different types and scales of interventions. The proposed technique could be used in urban planning processes to examine the potential SWB benefits of green infrastructure investments prior to their being rolled out.
A quantitative and qualitative evaluation of the sustainability of industrialised building systems: A bibliographic review and analysis of case studies
(Elsevier Ltd, 2022) López Guerrero, Rafael Eduardo; Vera Araya, Sergio Eduardo; Carpio Martínez, Manuel; CEDEUS (Chile)
The building construction has a significant impact on sustainability worldwide. However, industrialised building systems (IBS) might reduce these impacts compared to traditional building systems (TBS). Previous literature reviews have analysed IBS's sustainability, based primarily on environmental aspects and through qualitative indicators, disregarding a detailed quantitative comparison between both technologies and nor considering economic and social sustainability indicators. To fill this gap, this paper aims to evaluate vis-à-vis IBS's sustainability in relation to TBS, based on the quantitative and qualitative indicators studied in the literature. Thus, an exhaustive bibliographic review of IBS and TBS case studies was conducted. In total, 67 scientific papers were selected (papers, book chapters and reports), containing 86 case studies. Major findings indicated that IBS are more sustainable in almost all studied values – except construction costs. Nevertheless, this advantage depends on material design, prefabrication levels, transportation, work management and each author's methodological approaches. These factors are discussed to explain the reasons for IBS′ sustainability. Furthermore, main conclusions indicate that sustainability assessments have been unbalanced in literature, with few analyses of economic and social performance, and some indicators have been poorly studied (e.g., water and acidification potential), so their results are not yet representative. Similarly, reusability, prefabrication levels and the social indicators of IBS were insufficiently analysed in the reviewed case studies. Finally, the current review highlights IBS sustainability indicators that have been less studied in order to motivate new investigations in the broader field, exposing the IBS sustainability outlook and other research gaps.
A “landscapes of power” framework for historical political ecology: The production of cultural hegemony in Araucanía-Wallmapu
(2020) Escalona Ulloa, Miguel; Barton, Jonathan R.; CEDEUS (Chile)
The region of Araucania, since its incorporation into the Republic of Chile, has been subject to significant territorial transformations. The Chilean State, supported by economic elites, the political class, and intellectuals have all contributed to the discursive positioning of, and the creation of artefacts in, this regional space. These devices for mobilising power have enabled an appropriation of nature – through natural resource exploitation – and an appropriation of land rights through property titles. The occupation of Araucania from the end of the 19th century was achieved principally through the artefacts of larger settlement consolidation, the railway network, and the building of roads. These were designed and imposed from Santiago through political and administrative channels based on an internal colonialism logic. Conflicts with indigenous Mapuche in Wallmapu (the Mapudungun name for their territory) arose as a consequence of asymmetries of power and this appropriation of space, including expulsion from their land, deforestation, increasing poverty due to restricted access to traditional resources, and epistemic violence through specific constructions of development and the subalterning of indigenous “others.” This historical political ecology not only reveals the expanding frontiers of extractivism and processes of accumulation in favour of national political and economic elites, but more importantly shows how the construction of cultural landscapes became a device for exercising power and justifying appropriation in pursuit of modernity, progress, and development. These landscapes of power evolved over time as different demands were placed on this territory: first as a wheat bowl, and second as forestry plantation. A “landscapes of power” framework is presented in order to work through these constructions of landscape, building on phenomenological and dwelling perspectives in order to focus on the role of cultural hegemony and power relations.

Acceder caminando a los humedales urbanos: una opotunidad de recreación y bienestar
(Universidad del Bío Bío, 2022) Rojas Quezada, Carolina Alejandra; Jorquera Guajardo, Felipe Ignacio; Steiniger, Stefan; CEDEUS (Chile)
Los humedales de las ciudades chilenas constituyen uno de los ecosistemas urbanos más afectados por los desarrollos inmobiliarios. A pesar de sus valores en recreación y en biodiversidad, sufren una constante pérdida de superficie, debido a deficientes procesos de planificación urbana. Sin embargo, ante el auge de las ciudades verdes y sustentables, se están revalorizando por medio de proyectos de restauración y de parques urbanos abiertos, de valor natural para el bienestar de los hábitats y la población. En este sentido, propiciar una accesibilidad con una infraestructura adecuada aportará a mejorar la calidad de vida de los habitantes y por supuesto del entorno urbano, concretamente a través de la integración de infraestructura verde-azul (blue-green infrastructure). Con la finalidad de contribuir al acceso a la naturaleza en ciudades, se realiza aquí un análisis de accesibilidad a pie, a una red de humedales llamada “La Ruta del Agua”, mediante una encuesta de percepción. Los humedales urbanos evaluados son 5 ecosistemas con distintos entornos barriales en Concepción Metropolitano (Chile). Si bien se trata de un caso de estudio local, representa una contribución metodológica relevante, dada la existencia de una gran cantidad de humedales urbanos degradados en Latinoamérica y en peligro de desaparecer. Los resultados de acceso muestran que los humedales son accesibles por vía de la caminata, pero el hecho de que sean poco visitados, pese a su cercanía a las zonas residenciales, revela su falta de integración como espacios abiertos, verdes, ricos en biodiversidad y aptos para la recreación en la ciudad de Concepción. Los resultados de este estudio son valiosos para el diseño de futuros de proyectos de parques en humedales, parques que deben considerar los valores ecosistémicos, la biodiversidad y la recreación para el bienestar de las personas.
Accesibilidad a equipamientos colectivos según movilidad y modos de transporte en una ciudad media, Los Ángeles, Chile
(Universidad Compultense Madrid, 2019) Rojas Quezada, Carolina Alejandra; Martínez Bascuñán, Marcela; De la Fuente Contreras, Helen; Schäfer Faulbaum, Andrés; Aguilera Saéz, Felipe; Fuentes Mella, Gloria; Peyrín Fuentes, Consuelo; Carrasco Montagna Cruz, Juan
La relación entre distribución de equipamientos y servicios en sus diferentes ni-veles de accesibilidad según modos de transporte, muestra una serie de patrones espaciales de movilidad en la ciudad de Los Ángeles (Chile). El estudio analiza la accesibilidad a equipamientos colectivos en modos de transporte, mediante una serie indicadores cuantitativos, utilizando análisis de redes. Se emplean datos de viajes en modos de transporte privado, público y caminata, de la encuesta Origen-Destino (2004). Los resultados evidencian diferencias en la accesibilidad entre el centro y periferia de Los Ángeles. De hecho, la población del centro tiene alta acce-sibilidad, concentrando las mayores y mejores oportunidades. En contraste, la po-blación periférica en crecimiento que, en su mayoría, viaja largas distancias para acceder, especialmente en caminata. Este análisis contribuye a discutir sobre las implicancias de las oportunidades y el papel del transporte en la movilidad de ciu-dades medias de Latinoamérica con un centro preponderante.
Accessibility and land value as criteria for a rational locali zation of rural social housing in San Bernardo and Calera de Tango, ChileAccesibilidad y valor de suelo como criterios para una locali zación racional de vivienda social rural en las comunas de San Bernardo y Calera de Tango, Chile
(Universidad de Chile, Instituto de la Vivienda, 2014) Salazar Burrows A.; Cox Oettinger T.; CEDEUS (Chile)
The lack of social housing planning for rural areas in Chile and the high value of land in consolidated areas have resulted in the emergence of poorly localized developments in terms of access to opportunities. In the current scenario of self-management in the purchase of land, this research aims to explore a methodology intended to contribute to well-informed decision making, considering that accessibility and land value are essential to achieve an economically sustainable location. This dissertation proposes an indicator that includes land value (initial cost of localization) and accessibility to services (future costs of localization) in the municipalities of San Bernardo and Calera de Tango Chile, Metropolitan Region. These two variables are spatialized in raster format in order to develop a land accessibility-value indicator. Results show a wide disparity in the access costs between urban and rural areas and reinforce a decentralized concentration based on the supply of services and networks provided in areas of lower value than those of consolidated areas.
Adaptive capacity as local sustainable development: contextualizing and comparing risks and resilience in two chilean regions
(MDPI, 2021) Barton, Jonathan Richard; Gutiérrez-Antinopai, Felipe Aníbal; Escalona Ulloa, Miguel; CEDEUS (Chile); Pontificia Universidad Católica de Chile. Instituto de Geografía
Regional resilience refers to an immanent condition for facing multiple risks on a permanent basis, both episodic and incremental. These risks are not only linked to natural disasters and climate change, but also to poverty and inequality of access to services such as health, and personal safety. This article considers the underlying conditions that shape regional resilience in Chile, based on inter-regional and intra-regional comparisons in the Metropolitan Region of Santiago and the Region of Araucanía. Instead of viewing resilience in terms of an ability to counter a single risk, the article highlights the fact that risks are multiple and overlapping over time and generated at different scales. Municipal level data on poverty, health, and public finances in the two regions reveal the contrasting underlying inequalities that point to regional mosaics of resilience rather than homogeneity. Different threats are superposed on these preexisting conditions of resilience. The article refers to three in particular: the 2010 Chilean earthquake (episodic); climate change (episodic and incremental); and the Covid-19 pandemic (episodic). The findings point to high levels of urban versus rural differentiation, and also high differentiation within the Santiago Metropolitan Area based on socio-economic conditions. This regional mosaic of underlying structural conditions suggests that regional resilience can be enhanced by engaging with structural socio-spatial inequalities rather than a focus on managing risks via siloed, threat-by-threat responses.
Aportes y desafíos del Sistema de Evaluación de Impacto Ambiental (SEIA) a la conservación de la biodiversidad en Chile
(Interuniversity Institute of Geography and University of Alicante, 2019) Henríquez Ruiz, Cristian Gonzalo; CEDEUS (Chile); Pontificia Universidad Católica de Chile. Instituto de Geografía
Environmental impact assessment systems are preventive management instruments whose main objective is to include environmental considerations in the processes and activities accompanying economic growth in a nation. The influence of these systems in the conservation of biodiversity is fundamental, since within the evaluation process, they enable identifying and evaluating potential environmental impacts, as well as defining reparations, compensations, or mitigations. Halting the loss of biodiversity caused by human activities and climate change is a global objective. Chile is also facing this challenge, considering its status of Biodiversity Hotspot, projections associated with climate change, and the outstanding issues that the Environmental Impact Assessment System (SEIA) shows regarding biodiversity conservation. The latest, based on the lack of strategic view when considering issues such as the territorial scope of the environmental impacts generated by the projects, under a systemic and transversal approach. This research analyses the main changes experienced since the creation of SEIA, and compares this system with other evaluation systems used in Latin America. National statistics on investment projects potentially affecting the conservation of biodiversity are given. Two issues are addressed to guide discussion of the operational changes that should be encouraged by the Chilean government, namely: 1) internalising the importance of protecting biodiversity beyond current regulations, and; 2) introducing improvements in environmental legislation that could indirectly lead to improvements in SEIA. The research concludes on the importance of strengthening the Strategic Environmental Assessment (SEA) and its integration with the SEIA, in order to encourage better project designs by including sustainability from the beginning.
Association between maternity leave policies and postpartum depression: a systematic review
(Springer, 2023) Hidalgo-Padilla, Liliana; Toyama, Mauricio; Hanae, Jessica; Tanaka, Zafra; Vives Vergara, Alejandra; Diez-Canseco, Francisco; CEDEUS (Chile)
Purpose: Working mothers are at greater risk for postpartum depression. Maternity leave characteristics, including length, wage replacement and employment protection, could have relevant implications for mothers’ mental health. We propose to explore whether there is an association between maternity leave characteristics and postpartum depression. Methods: We conducted a systematic review searching for randomized controlled trials, quasi-experimental, cohort or cross-sectional studies on five databases using search terms including maternity and parental leave and depression, as well as references in relevant articles. We identified 500 articles and included 23 of those. We used the EPHPP Quality Assessment Tool for Quantitative Studies to assess the quality of the studies. Results: Paid and longer maternity leaves tend to be associated with a reduction of postpartum depression symptoms in high-income countries. No studies explored the association between employment protection and postpartum depression. The quality of studies ranged from strong to weak, mostly influenced by study design. Conclusion: More restrictive maternity leave policies tend to be associated with higher rates of postpartum depression, although more research needs to be conducted in the Global South.
Barreras estructurales en la caminabilidad y accesibilidad a escala de barrio. Estudio de tres casos en Santiago de Chile
(2020) Berrios Álvarez, Emilio Moisés; Greene, Margarita; CEDEUS (Chile)
Dada la relevancia de la accesibilidad a bienes y servicios urbanos en la calidad de vida de los habitantes, y considerando que la caminata representa el principal modo de transporte en el Gran Santiago -34,6% de los viajes, según la Encuesta de Origen y Destino de 2012 (Universidad Alberto Hurtado, 2014)-, la presente investigación tiene como objetivo analizar y comparar las barreras estructurales que inciden en el área caminable a escala de barrio y estimar sus posibles efectos en los patrones de movilidad y acceso a bienes y servicios, en tres conjuntos habitacionales del Gran Santiago: población Juan Antonio Ríos sector 3B (Independencia), villa San Cristóbal (Recoleta) y villa Los Sauces (La Florida). Para cada caso, se identificaron las principales barreras materiales, ya sean naturales (ríos, cerros) o artificiales (carreteras, pasos bajo/sobre nivel) y algunas barreras intangibles (asociadas a la seguridad vial o delictual). Se comparó la superficie teórica máxima del barrio caminable (euclidiana) con la “real” calculada mediante análisis de red (sobre la base de recorridos de 20 min), considerando las condiciones de cruce de las principales vías, cuantificando sus efectos en tiempo y distancia y la consiguiente accesibilidad a equipamiento y servicios. Además, se analizó la configuración de la trama vial y peatonal, contrastando su integración a escala local y global basada en mapas axiales. Finalmente, se analizaron los patrones de movilidad de la población según datos de zona EOD 2012. Los resultados muestran una clara disminución del área real del barrio caminable (a un tercio del área euclidiana), producto de la trama y de las diversas barreras existentes, lo que se refleja en la accesibilidad a bienes y servicios vía caminata. Estos resultados permiten proponer además que, si bien una mayor distancia promedio de caminata no se relaciona con una mayor área caminable, la cercanía a centralidades sí se asocia con la prevalencia de este modo de transporte.
Caminando a los parques urbanos: Calidad y acceso público
(Universidad Austral de Chile, 2020) Rojas Quezada, Carolina Alejandra; De la Fuente-Contreras, Helen; Díaz-Muñoz, Sebastián; Rueda-Seguel, Ivonne; Olguín-Carrillo, Natalia; Gallardo, Marta; CEDEUS (Chile)
Los parques urbanos son espacios verdes caracterizados por su concepción multifuncional que incorpora, junto a la vegetación y las áreas de paseo y estanciales, zonas de juego, deportivas o de ocio. Por su tamaño y composición aportan beneficios sociales y físicos a la ciudadanía además de ecológicos y medioambientales a la propia ciudad. Vivir próximos a ellos es clave para mejorar la calidad de vida. Este estudio mide el acceso a pie de residentes con diferentes perfiles demográficos a trece parques urbanos clasificados según su calidad en la ciudad de Concepción, Chile. Los resultados muestran que los adultos y niños disponen de un acceso expedito a parques de calidad, mientras que los adultos mayores, aquejados de mayores problemas de movilidad y una distribución residencial más central, presentan los peores datos independientemente de la calidad de los parques existentes
Can Strategic Environmental Assessment (SEA) contribute towards the implementation of biophilic urbanism in urban planning? The case of Chilean Municipal Regulatory Plans
(Elsevier Inc., 2022) Carter V.; Henriquez C.; Henriquez C.; CEDEUS (Chile)
© 2022 Elsevier Inc.The COVID-19 crisis has again highlighted our need to be in close contact with nature. Approaches such as biophilic urbanism, which seek to re-naturalize cities through its inclusion in planning and design, have thus gained relevance. The biophilic urbanism approach is materialized through the Biophilic Cities Network (BCN) and uses indicators to measure cities' biophilic performance. To date, Chilean cities have not formally implemented the approach. However, the Strategic Environmental Assessment (SEA), a mandatory policy process, requires the inclusion of environmental issues in Chilean urban planning. The purpose of this paper is to explore the extent to which SEA might contribute towards the implementation of biophilic urbanism in planning processes. We analyze how local governments have been including biophilic elements in their SEA processes by exploring the Communal Regulatory Plan (PRC). We perform a content analysis on the indicators in 135 reports associated with each SEA process. The analysis revealed 286 of 1,006 indicators containing biophilic elements extracted from the biophilic cities indicators. We found that biophilic elements linked with the inhabitant's engagement and well-being were largely absent. Conversely, those indicators related to the creation of new green urban infrastructures were widely represented. Overall, the paper hints at the potential usefulness of the SEA to increase biophilic urbanism implementation in urban planning by applying indicators that include biophilic elements.
Characterizing the public transport service level experienced by users: An application to six Latin American transit systems
(2022) Batarce, Marco; Muñoz Abogabir, Juan Carlos; Torres Rivas, Ignacia; CEDEUS (Chile)
We present a method oriented to determine indicators representing different dimensions of users' travel time, such as in-vehicle time and its variability. We focus the service level measurement on users, but not their subjective perception, since we build the indicators from objective data. We apply the method to six Latin American cities, which shows the method's flexibility to fit different available information collected from sources such as in-field measurements or electronic control systems for bus operations. The method's core is the selection of a representative sample of trips. We estimate the service level based on different variables (e.g., speed, frequency, travel time, and waiting time) for every sampled trip. The contribution of this work is the design and implementation of a methodology for service level evaluation. As a byproduct, we compare public transportation systems' levels of service in the studied cities.
Consideraciones para programar la regeneración de condominios sociales en altura. Estudio comparado de tres casos en Chile
(Universidad de Chile, Instituto de la Vivienda, 2020) Chateau Gannon, Francisco; Schmitt Rivera, Cristián; Rasse, Alejandra; Martínez Torres, María Paula; CEDEUS (Chile)
El Programa de Regeneración de Conjuntos Habitacionales (PRCH) del MINVU ha venido a hacerse cargo de la necesidad urgente de reducir el déficit cualitativo de la vivienda social y mejorar los edificios de condominios en altura. A partir del aprendizaje de las primeras experiencias se elaboró un modelo de gestión donde se pueden constatar una serie de problemáticas derivadas de los largos plazos de ejecución de estos proyectos. El presente estudio identifica las dimensiones de la gestión, diseño e implementación de procesos que permitirían reducir sus plazos de aplicación, por medio de un análisis comparativo de tres casos de estudio en desarrollo. En la etapa de diagnóstico, se recomienda la reorganización de los estudios requeridos; y en la etapa de construcción, reconsiderar la tecnología aplicada a los sistemas constructivos, que posee un impacto relevante en los plazos de ejecución.
Covid-19 and city: Towards an integrated model of housing, microbiology, environment and urbanism
(2021) Encinas Pino, Felipe; Soto Liebe, Katia; Aguirre Nuñez, Carlos;; González, Bernardo; Bustamante Gómez, Waldo; Schueftan, Alejandra; Ugalde, Juan; Blondel, Carlos; Truffello Robledo, Ricardo; Araya, Paz; Freed Huici, Carmen Marcela; CEDEUS (Chile)
As of May 2020, the global health crisis caused by the SARS-CoV-2 virus moves its epicentre to Latin America, with cities showing high rates of poverty, segregation, and overcrowding. Current advances in microbiology make it possible to understand in depth the relationships between cities, COVID-19, and other microorganisms, but a conceptual framework to articulate them is lacking, especially in contexts where social determinants are so relevant. This article proposes an integrated approach to microbiology, housing, environment, and urbanism, based on a model of interactions and an empirical analysis applied to Santiago de Chile. It was possible to analyse how the propagation of COVID-19 in the city is enhanced by vulnerabilities of socio-spatial, residential and urban health, including an approach from the concept of energy poverty. At the same time, it was possible to verify how the variables associated with these vulnerabilities allowed to explain the incidence rate per 100 000 inhabitants through the different communes of Santiago de Chile. Among these, the level of housing overcrowding, the number of households with heads of household in precarious employment, and travel to the central business district stand out. Finally, the need for microbiological sampling to improve housing conditions, neighbourhoods, and cities propose a new research agenda for this Urban Microbiome" multidisciplinary team, contributing to overcoming the vulnerabilities identified in this research.
COVID-19 and Precarious Employment: Consequences of the Evolving Crisis
(SAGE Publications Inc., 2021) Matilla-Santander, Nuria; Ahonen, Emily; Albin, María; Baron, Sherry; Bolíbar, Mireia; Bosmans, Kim; Burström, Bo; Cuervo, Isabel; Davis, Letitia; Gunn, Virginia; Håkansta, Carin; Hemmingsson, Tomas; Hogstedt, Christer; Jonsson, Johanna; Julià, Mirei; Kjellberg, Katarina; Kreshpaj, Bertina; Lewchuk, Wayne; Muntaner, Carles; O’Campo, Patricia; Orellana, Cecilia; Östergren, Per-Olof; Padrosa, Eva; Ruiz, Marisol E.; Vanroelen, Christophe; Vignola, Emilia; Vives Vergara, Alejandra; Wegman, David H.; CEDEUS (Chile); Department de Salud Pública.Pontificia Universidad Católica de Chile
The world of work is facing an ongoing pandemic and an economic downturn with severe effects worldwide. Workers trapped in precarious employment (PE), both formal and informal, are among those most affected by the COVID-19 pandemic. Here we call attention to at least 5 critical ways that the consequences of the crisis among workers in PE will be felt globally: (a) PE will increase, (b) workers in PE will become more precarious, (c) workers in PE will face unemployment without being officially laid off, (d) workers in PE will be exposed to serious stressors and dramatic life changes that may lead to a rise in diseases of despair, and (e) PE might be a factor in deterring the control of or in generating new COVID-19 outbreaks. We conclude that what we really need is a new social contract, where the work of all workers is recognized and protected with adequate job contracts, employment security, and social protection in a new economy, both during and after the COVID-19 crisis.
Disciplinary inflections: Contesting three concepts for the construction of the post-neoliberal cityInflexiones disciplinares: disputando tres conceptos para la construcción de la ciudad posneoliberal
(Pontificia Universidad Catolica de Chile 1, 2021) Encinas F.; Encinas F.; Truffello R.; Tironi M.; Truffello R.; Aguirre C.; Aguirre C.; Freed C.; Vergara-Perucich F.; Hidalgo R.; Tironi M.; CEDEUS (Chile)

By understanding this performative condition, this text analyzes the current implications of the concepts of sustainability, resilience, and integration. Then, it argues the need to overcome the neoliberal city if we want these meanings to become real.
Economic and Environmental Impact of Military Electrical Vehicle Conversion and Solar Electricity Production
(2020) Pierre Simon, François; Roberts, C.; Girard, Aymeric; Ordoñez, Javier; Rossel, G.S.; CEDEUS (Chile)
Military vehicles carry out defence and training functions; however, they also participate extensively in military operations apart from war, such as supporting citizens in emergency situations. Nonetheless, they continue to contribute to pollution, and carbon emissions in Chile have doubled in recent years. Thus, this study seeks a partial solution to this problem, extending the useful life of an archetypal military vehicle, i.e. AIL Storm internal combustion engine vehicle (ICEV), 4.0L gasoline, through its conversion into an electric vehicle (EV) using lithium-ion batteries. AIL Storm ICE emissions are compared with an equivalent EV conversion prototype, analysing the CO emissions of the EV charged from the Chilean electricity grid or from a solar photovoltaic charging station, taking advantage of the high levels of solar radiation in Chile. This studied model obtains a travel cost of 0.04USD/km in the electric grid charge mode and 0.02USD/km in the Solar power station charge mode, affecting the environment with 155kgCO2 emissions per year of use. In the future, technologies to manufacture or assemble lithium batteries must be developed in the Chilean market. Given the availability of this mineral in Chile, this step would reduce costs and make electric mobility more attractive and affordable.
Effects of an urban regeneration program on related social determinants of health in Chile: A pre-post intervention study
(Elsevier Ltd, 2021) López-Contreras, Natalia; Puig-Barrachina, Vanessa; Vives Vergara, Alejandra; Olave-Müller, Paola; Gotsens, Mercè; CEDEUS (Chile); Pontificia Universidad Católica de Chile. Escuela de Medicina
Urban regeneration programs, such as “Programa Quiero mi Barrio” (PQMB) that is carried out in neighborhoods with greater deprivation across Chile, can improve health and quality of life in socio-economically deprived neighborhoods. The aim of this study was to analyze the effects of this program on the physical, social, and safety environments of neighborhoods intervened between 2011 and 2018, according to gender and socioeconomic position. Four indices and six sub-indices were constructed to measure physical, social, and safety environments of the neighborhoods. We conducted a pre- and post-intervention analysis with 2095 people using linear models adjusted for repeated measurements. After the intervention, participants had an improved perception of physical, social, and safety environments, as well as the use of spaces, particularly among women and people with higher levels of education. Therefore, the PQMB program is a form of public policy that can improve the quality of life and health of people living in underprivileged areas.
