- ItemA “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.

- ItemAdaptive 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 GeografíaRegional 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.
- ItemAportes 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 GeografíaEnvironmental 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.
- ItemCovid-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.
- ItemCuánto consumo supone el bienestar. Una geografía urbana basada en un índice de Sustentabilidad comunal en Chile(Scielo, 2023) Gutiérrez Antinopai, Felipe Aníbal; Barton, Jonathan Richard; CEDEUS (Chile); Pontificia Universidad Católica de Chile. Instituto de GeografíaIn the context of the UN 10-year Framework Programmes on Sustainable Production and Consumption (2012-2022), it is necessary to understand consumption patterns, mainly in urban areas. The municipal geography of consumption establishes a radical change in understanding urban sustainability merely as a challenge of poverty and low consumption. Through an Urban Sustainability Index, we identify patterns that reveal material processes and opportunities for wellbeing and levels of consumption. Focusing on the urban metabolism and indicators of impacts on intergenerational wellbeing, the index shows high levels of consumption in four municipalities and notable gaps in material and social conditions at the national and intra-regional scales. The article presents the municipal geography of wellbeing and consumption in Chile, in order to reveal the condition of urban sustainability to guide improvements in material and social conditions uncoupled from consumption. It also warns of the particular paradoxes of the development process.
- ItemFlue gas desulfurization (FGD) fly ash as a sustainable, safe alternative for cement-based materials(2021) Navarrete Leschot, Iván Ignacio; Vargas Muñoz, Felipe Andrés; Paul, Álvaro; López Casanova, Mauricio Alejandro; Martínez, Patricia; CEDEUS (Chile)The reduction in fly ash production in coal-fired power plants has created an opportunity to explore alternative types of fly ashes previously deemed unfit for use in concrete. In plants using flue gas desulfurization (FGD) processes, fly ash could contain high amounts of sulfur oxides, making its use in concrete inadvisable. However, the type of sulfur compound present in a fly ash strongly impacts its performance in concrete. In this study, two types of fly ash were used to evaluate the effect of sulfur oxides on mortar mixtures incorporating fly ash as supplementary cementitious material (SCM); one from an FGD unit, with high sulfur oxide content (in the form of hannebachite), and the other generated in a system without FGD, with negligible sulfur oxide. Calorimetry results show that hannebachite can effectively control C3A hydration similar to gypsum; however, its presence in FGD fly ash does not induce deleterious expansion associated with internal sulfate attack in mortars. TGA and XRD analyses suggest that hannebachite has lower reactivity than sulfate. Hannebachite not only maintains the pozzolanic reactivity of the fly ash, but its fineness may promote OPC hydration, increasing compressive strength. The results of this study indicate that FGD fly ash can be used as an SCM, allowing more sustainable concrete production.
- ItemForeign direct investment, local development and poverty reduction: the sustainability of the salmon industry in Southern Chile(2014) Fløysand, Arnt; Barton, Jonathan Richard; CEDEUS (Chile)The rate of Foreign Direct Investment (FDI) has risen dramatically during the past three decades; developing countries’ inward stock of FDI amounted to about 30 per cent of their GDP in 2009, compared to just 12 per cent in 1980 (UNCTAD 2011). This has led to a great deal of optimism that FDI can provide a potential for economic development and poverty reduction. However, this potential depends on how FDI interacts with the environment in which the investments take place (Lall and Narula 2004, Moran et al. 2005). To discuss these types of interaction, we propose an analytical framework approaching FDI as consisting of capital, actors and knowledge, or what we call the capital–actor–knowledge complex.
- ItemIncome inequality and efficient resources allocation policy for the adoption of a recycling program by municipalities in developing countries: The case of Chile(Elsevier Ltd, 2021) Araya-Córdova, Patricio J.; Dávila, Sebastián; Valenzuela Levi, Nicolás; Vásquez, Óscar C.; CEDEUS (Chile); Pontificia Universidad Católica de Chile. Instituto de Estudios Urbanos y TerritorialesThe question about how to choose the best recycling policy is particularly relevant in developing countries. On the one hand, many of these countries have no national waste management strategies, with recycling programs emerging as an independent initiative financed by municipalities, mostly in urban areas. On the other hand, the municipal budget tends to be linked to the wealth of their inhabitants. Consequently, an efficient municipal resources allocation policy to support recycling programs is especially crucial for the most vulnerable population, often located in rural areas. In this paper, we address the problem of optimal allocation of resources for the adoption of a recycling program by municipalities located in both urban and rural areas of a developing country, determining the best combination between two options: increasing and redistributing existing resources. Our research methods involve comprehensive data collection and mathematical modelling, adopting a logistic regression model proposed in the literature, formulating a non-linear optimisation model, and implementing a resolution method. In addition, recycling policies with equivalent results are described and analysed, discussing their political feasibility and economic efficiency. To illustrate our proposal, the case of Chilean municipalities is considered. Chile is a country from the Global South that belongs to the OECD and can be therefore compared to other documented cases. Although no official national data is available, we were able to collect figures by requesting information from every municipality in the country. The obtained results show an important lack of resources at the national level in MSWM, especially affecting rural areas. In this context, equivalent recycling policies with combined options could better favour rural municipalities. However, the average probability for the adoption of a recycling program by municipalities, although shows slight increases, is not enough for a substantial change towards a more sustainable waste management model. Our results illustrate the gap between urban and rural municipalities, the need to inject important funds into the system as a whole, and open the question of whether a more direct ‘command and control’ policy is required instead of just trusting the individual initiative of each municipality, even if more resources are provided.
- ItemModelling and simulation of the wood biomass supply from the sustainable management of natural forests(2021) Pierre Simon, François; Girard, Aymeric; Krotki, Martin; Ordoñez, Javier; CEDEUS (Chile)Wood biomass is an important energy resource, which can contribute to reduce the dependence on fossil fuels. The research undertakes the microeconomic approach to estimate the technical availability and operational costs of woody biomass production with a higher level of precision than other models present in the literature, as it considers the entire supply chain of the sustainable management of natural forests. This study introduces a tool, which is applied to estimate supply curves and costs of wood biomass extraction from natural forests in the 7th Region of Chile. The simulation indicates that 531,015 tons/year of wood biomass is available in natural forests of the Region under study, with extraction costs ranging from 24.51 to 56.68 US$/ton, or an average total cost of 40.97 US$/ton. The parametric analysis revealed that the maximum admissible distance to the nearest transport route and the transportation costs are the two most influential variables in the estimation of wood biomass supply and cost. Reducing the admissible distance from 5 km to 1 km reduced the availability of biomass by 80%, while a variation of ±50% of transportation costs translated into ±18.3% variation of total extraction costs. The proposed method can be used to identify the technical-economic potential of wood biomass from natural forests in any commune, province, region, or country; as it has the flexibility to allow tests with multiple scenarios and parameters depending on the specific characteristics of the area to be analysed. Essentially, the purpose of this tool is to serve the assessment processes of the identification of new wood biomass resources, allowing decision makers to increase the potential of sustainable and cost-effective woody biomass for heat and electricity generation, and at the same time reduce greenhouse gas emissions and the dependence on fossil fuels.
- ItemPerception of thermal comfort in outdoor public spaces in the medium-sized city of Chillán, Chile, during a warm summer(2019) Smith Guerra, Pamela; Henríquez, Cristián; CEDEUS (Chile)The study of thermal comfort in Latin American cities has been gaining great relevance for urban environmental planning. Some studies have evaluated the relationship between environmental and perceived comfort; however, the causes and social determinants of the different perceptions of the population have not been explored. The perception of thermal comfort in public spaces in the city of Chillán (Chile), which has an inland Mediterranean climate, is discussed in this context. First, we measured the environmental thermal comfort, adapting the Actual Sensation Vote index. A survey of 362 users of the five selected public spaces was carried out between 29 January and 01 February 2016 to obtain perceived comfort and relate it to the individual climatic history, use of public space and place of residence in the city. The results show that perceived thermal discomfort dominates over comfort on summer days; however, those users who visit public spaces for recreational purposes feel more comfortable, as well as those living in low socioeconomic status (SES) neighborhoods. On the other hand, users living in areas with higher socioeconomic status, have higher expectations regarding thermal environmental conditions.
- ItemThe role of planning policies in promoting urban sprawl in intermediate cities: evidence from Chile(MDPI, 2019) Barton, Jonathan Richard; Ramírez, María Inés; CEDEUS (Chile); Pontificia Universidad Católica de Chile. Instituto de Estudios Urbanos y TerritorialesUrban sprawl has been studied principally as a phenomenon produced by a lack of or weakness in urban planning, as a consequence of real estate liberalization. This article examines the Chilean case, and proposes that the state has been the engine of this phenomenon through spatial planning instruments that have both neoliberal and neostructural features, and that are best defined by the concept, new public management. The analysis tracks urban sprawl in four intermediate cities, which have experienced high rates of growth since 2000, using photointerpretation of satellite images between 2003 and 2011, and the creation of a typology to define land uses and housing types. The results show that intermediate cities follow similar trends to the capital city, Santiago, and face similar problems, in particular the concentration of services in the urban core. These similarities are produced by the application of general planning instruments: Article 55 and Decree Law 3516. While most research on urban sprawl focuses on private agency, this article highlights the role of the state in its production. It is therefore relevant to explore the nature of public agency in urban sprawl processes in different metropolitan and intermediate cities, and how planning policies can be adapted to curb the phenomenon.
- ItemUnderstanding cyclists’ conflicts in the streets of a Latin American metropolis(2024) Mora Vega, Rodrigo; Waintrub Santibáñez, Natan; Figueroa Martínez, Cristhian; Horta, Amarilis; CEDEUS (Chile)Promoted by most governments as a sustainable form of transportation, cycling is surging worldwide. Despite the positive impacts of cycling, conflicts between cyclists and other street users such as pedestrians, cars and buses have increased, especially in countries lacking proper cycling infrastructure. This paper aims to understand a series of conflicts experienced by cyclists in Santiago de Chile, where cycling has expanded rapidly in the last fifteen years. To do so, three focus groups were held with cyclists having different levels of experience. The participants were asked to describe the main conflicts with other modes of transport and road users, as well as the coping strategies employed to deal with these conflicts. An inductive analysis ended with four categories related to cyclists’ conflicts in the streets and two related to strategies and lessons dealing with motorised vehicle drivers and other cyclists. The analysis indicates that the unequal distribution of road space negatively influences cyclists’ experiences, who perceive themselves as being threatened constantly by overtaking cars in close proximity, as well as by different forms of verbal and sometimes physical aggression. It indicates that cyclists develop strategies to mitigate conflicts, ranging from making themselves visible at all times, to making use of bodily gestures. However, conflicts can still escalate. The results suggest that, in auto-centric urban contexts, cycling is a challenging chore that happens surrounded by the sensation of having fragile entitlements.
- ItemUrban resilience in the face of fossil fuel dependency: The case of Rio de Janeiro’s urban mobility(2019) Fernándes, Vicente Aprigliano; Rothfuss, Rainer; Hochschild, Volker; Da Silva, Marcelino Aurelio Vieira; Da Silva, William Ribeiro; Steiniger, Stefan; Dos Santos, Tálita Floriano; CEDEUS (Chile)Long-term scenarios for mobility within cities usually neglect the energy supply challenge and how the implied risks affect urban mobility services. High levels of private transport and fossil fuel dependency tend to prevail in urban agglomerations of modern cities in many parts of the world. The resilience approach supports a new perspective on transportation solutions, not only based on how to consume less energy or emit less CO2, but how vulnerable urban mobility is in face of a fossil threat. This paper aims to assess the vulnerability of urban mobility in the face of fossil fuel threats under a social and geographical scope. We apply a case study with the city of Rio de Janeiro, confronting city inhabitants with a price increase of gasoline and oil-based public transportation. We found that more than 50% of the districts of Rio de Janeiro presents low-medium or low level of resilience of urban mobility. Furthermore, they are in areas with lower accessibility to metro stations and more citizens with reduced income levels.
