BackgroundTemuco and Padre Las Casas, Chile, have severe problems of air pollution due to the extensive use of firewood for heating. The local authorities have made various efforts to improve fuel quality and introduce greater regulation into the market. Certified firewood guarantees low levels of humidity (MethodsThis study was conducted with a cross-sectional non-experimental design. Following a non-probability sampling by convenience, we applied 355 surveys to participants who use a firewood system. Nonparametric comparisons analyses were made to identify differences in the use of certified wood by socio demographic variables. In addition, an Ordinal Logistic Regression was used to analyze the relation between the use of certified firewood and various psycho-social variables.ResultsHalf of the users of wood-burning stoves participating in the study declared that they “never” (38%) or “almost never” (12%) used certified firewood to heat their home. Situational and product-related variables, such as price, availability, convenience and time are fundamental to people’s purchase behavior, partially explaining the low public interest shown in this product. On the other hand, the results indicate the influence of socio-demographic variables such as income level and the presence of older adults at home, as well as psycho-social variables which include how much participants pay attention to air quality, the information level they have about it, the feelings of discomfort due to air pollution and concern for its effects on health.ConclusionsFirst, increasing information levels and awareness among the population through communication campaigns is necessary to promote the sustainable urban energy transition in southern Chile. Second, information strategies may be complemented by boosting employment, driving investment, improving income, and strengthening the mechanisms of social protection, especially for the most vulnerable groups, to be effective. Finally, protecting and stimulating the formal trade in firewood could increase the points of sale of certified firewood, which would facilitate user access to cleaner fuels.

Enrolment in higher education has risen dramatically in Latin America, especially in Chile. Yet graduation and persistence rates remain low. One way to improve graduation and persistence is to use data and analytics to identify students at risk of dropout, target interventions, and evaluate interventions’ effectiveness at improving student success. We illustrate the potential of this approach using data from eight Chilean universities. Results show that data available at matriculation are only weakly predictive of persistence, while prediction improves dramatically once data on university grades become available. Some predictors of persistence are under policy control. Financial aid predicts higher persistence, and being denied a first-choice major predicts lower persistence. Student success programs are ineffective at some universities; they are more effective at others, but when effective they often fail to target the highest risk students. Universities should use data regularly and systematically to identify high-risk students, target them with interventions, and evaluate those interventions’ effectiveness.

Temuco and Padre Las Casas are two of the most polluted cities in southern Chile; around 90% of the particulate matter emissions are produced by wood-burning stoves used for domestic heating and cooking. Surveys were collected from 489 residents to examine differences between applicants and non-applicants to a programme to replace wood-burning stoves with pellet stoves. Results show that participants who applied to the programme are, on average, older than non-applicants, are more likely to have a respiratory impairment, tend to evaluate indoor air quality worse than non-applicants and tend to perceive the health effects of air pollution as more severe. The findings also suggest that motivation to improve air quality is a key aspect for understanding the adoption of pellet stoves when the requirement for initial investment is removed. Practical implications relating to the role of sociodemographic and psychological factors in the decision to replace heating systems are discussed to support the design of more effective interventions to mitigate wood smoke pollution.

Chile has embraced the expansion of monoculture forest plantations of exotic Monterey pine and eucalyptus as part of its development strategy. While forestry is considered financially successful and meets sustainability objectives, the increase in forest plantations across southern Chile has received harsh critiques for exacerbating conflict over Indigenous land rights, producing negative environmental outcomes, and increasing poverty and inequality. There are also claims that forest plantation expansion has led to an abandonment of the countryside. Migration is viewed as a result of the socioeconomic challenges that forest plantations produce at the local level, however, the linkages have not been explored. We examine the linkages between forest plantations and migration through two questions: Is there a relationship between forest plantation cover change and out-migration from rural areas? If so, what are the factors that explain this process? We use a difference-in-differences method analyzing panel data from the Chilean census and from CONAF, the Chilean National Forest Corporation, complemented by interviews, mapping workshops, and focus groups to answer these questions. Results indicate a statistically significant relationship between expanding forest plantations and population decline in rural areas. Qualitative data show that this expansion led to displacement of residents, declines in employment opportunities, and agriculture difficulties.

This study analyzes the role of the affect heuristic, risk perceptions, and air quality and sociodemographic factors in the support for policies to control urban air pollution. The sample includes 489 participants residing in Temuco and Padre Las Casas, suburban areas located in southern Chile, affected by the smoke that wood-burning stoves and cookers produce. In line with previous studies, the results show that the rejection of pollution mitigation policies is associated with a positive affect to heat homes with wood. Awareness and risk perception also seem to be relevant factors, but the effect of the latter on the support for policies ceases to be significant when it is controlled by key sociodemographic variables such as household income. The study findings contribute to the theories of processing information about risk, when suggesting that emotions and awareness play an important role in the support for policies to control air pollution and that, also, structural factors like household income cannot be avoided. Finally, the implications for urban energy transition processes are discussed.

In southern Chile, epidemiological studies have linked high levels of air pollution produced by the use of wood-burning stoves with the incidence of numerous diseases. Using a quasi-experimental design, this study explores the potential of participatory sensing strategies to transform experiences, perceptions, attitudes, and daily routine activities in 15 households equipped with wood-burning stoves in the city of Temuco, Chile. The results suggest that the experience of using a low-cost sensor improves household members' awareness levels of air pollution. However, the information provided by the sensors does not seem to improve the participants' self-efficacy to control air quality and protect themselves from pollution. The high degree of involvement with the participatory sensing experience indicates that the distribution of low-cost sensors could be a key element in the risk communication policies.

Various medium-sized cities in southern Chile are saturated by air pollution caused by woodsmoke. In this study, we developed a segmentation model to assess the public’s perceptions, understanding of health risks and emotional responses to poor air quality. To date, this is the first segmentation model dealing with public perception in cities contaminated by woodsmoke. A survey ( N = 489) was conducted in Temuco and Padre las Casas, Chile, which included questions regarding attitudes, sociodemographic factors, and health care behaviors, to obtain information for mitigation initiatives. Through a cluster analysis, three population segments were identified that related differently to environmental pollution, which were constructed based on seven psychosocial variables. Different sociodemographic profiles and self-reported behavioral patterns were found, which should guide policies aimed at improving air quality in cities contaminated by pollution from wood-burning stoves.
