The urbanization process in Latin America has reached unprecedented levels. The need to mitigate its effects and improve cities sustainability has become a pressing challenge. In this context, the assessment of sustainability acquires an increased recognition as a diagnosis tool to advance towards the ecological, social, economic and political objectives of sustainable development. On the basis of previous studies, this paper is intended to comparatively evaluate the urban and environmental sustainability of Mar del Plata city (Argentina) and its peri-urban area. A Sustainability Index (SI) was built. The most favourable SI values were generally found in the urban area, while the most critical ones were identified in the peri-urban area. The incidence of the topics in the SI, reveals differences between the urban and peri-urban areas. The outcome is expected to strengthen policy integration for present and future generations leading to the Sustainable Development Goals at a local scale.

Disaster risk warnings have been issued by the National Centre for Monitoring and Early Warning of Natural Disasters (Cemaden) to municipalities susceptible to floods and landslides in Brazil since December 2011. A survey of the end-users was developed in order to obtain an evaluation related to quality, anticipation and precision of the warnings. Using an explorative approach, a semi-structured questionnaire was available online to be filled in by the individuals responsible for receiving the warnings. The analysis of the results was supported by statistical techniques, to allow association among the variables. The majority of the users did not report difficulties in understanding the warning texts. However, they reported the inefficiency in receiving warnings by email and suggested that faster tools would be a better solution, i.e. a short message service. The improvements in the alerts could be informed by the results achieved in this survey.

Wood cookstoves are common in the Brazilian semiarid region. Most families use traditional versions,which have a series of social, environmental and health-related impacts. “Improved cookstoves” referto cleaner and more efficient cookstoves. These include adaptations that improve energy efficiency and reduce indoor air pollution, bringing benefits such as the reduction of firewood consumptionfor cooking, reduction of the emission of polluting gases originating from firewood burning andfewer health impacts, also contributing to forest conservation. Although the improved cookstovessector is still relatively underdeveloped in the Brazilian semiarid region, in recent years interest inthese technological alternatives has increased. In this context, the present study contributes to thecompilation and organization of information referring to the use of improved cookstoves in the Braziliansemiarid region.

Baseado em um survey com 1.064 domicílios do Seridó potiguar, região do semiárido nordestino, este trabalho discute como os indivíduos ajustam respostas de mobilidade ao perceberem os impactos das estiagens sobre os meios de subsistência. Nossos resultados mostram respostas usualmente de curto prazo envolvendo mobilidade cotidiana ou sazonal em relação à mudança permanente de residência. Também foi possível observar maior participação feminina nesses tipos de mobilidade, o que indica associação com o seu caráter de curta distância. Os programas sociais mostraram grande relevância nesse processo, com a possibilidade de duplo efeito: apoiando famílias sem emigrantes ou subsidiando a emigração de pelo menos um morador. Por fim, conclui-se que a migração e/ou a oferta de trabalho nos espaços urbanos foram ferramentas importantes para as famílias lidarem com o risco ambiental, o que requer instituições fortalecidas para gerenciar os potenciais impactos negativos para as regiões de destino desses indivíduos.

This research aims to identify the influence of two paradigms, namely colonial thinking and postcolonial thinking, on the valuation of native fruits, The sample was composed of six groups of farmers from the agroecology center Luta Camponesa Nucleus, which is linked to the agroecology network Rede Ecovida de Agroecologia, and the methodological procedures were based on the principles of action research. It concludes that the colonial thinking contributes to the elimination of native fruits, as a result of epistemicide, the advancement of the green revolution, and the food empires. On the other hand, the postcolonial thinking valorizes native fruits, especially through the ecology of knowledges, agroecology, and short circuits.
本研究旨在确定殖民思维和后殖民思维两种范式对本土水果估价的影响。样本由农业生态学中心Luta Camponesa Nucleus的六组农民组成，该中心与农业生态学网络Rede Ecovida de Agroecologia相连，方法论程序以行动研究原则为基础。它得出的结论是，殖民思想有助于消除本土水果，这是认识论杀戮、绿色革命和粮食帝国的进步的结果。另一方面，后殖民思想对乡土水果进行了估价，特别是通过知识生态学、农业生态学和短路。

In this text, we will discuss the interdependence in processes that influence, directly or indirectly, the conditions of natural resources’ appropriation and list social interactions that will draw corresponding institutional frameworks to which dwellers of the Tapajós-Arapiuns Extractive Reserve will affiliate. The research that supports this paper has a multidisciplinary character, relying on the usage of various tools for obtaining information. The analytical notion of institutions (formal and informal rules) has been used to reference the developed interpretations. The considered object of analysis reflects over practices in thedwellers’ way of life, taking into account the alternatives of correlation between social organization and production practices. It is perceived that dwellers’ social frameworks of organization were constructed, not only by traditional institutional apparatus, but also by using coordination instruments and landuse planning, to manage common resources. These principles create an institutional order based on a presumed rationality, with distinct unfoldings and social impacts.

Family farmers of semi-arid regions are especially vulnerable to climate change, due to the reliance on rain-fed production systems and the limited capacity to cope and adapt to impacts. The Brazilian Food Acquisition Program (PAA), as an example of a food procurement program that also functions as a food-based safety net for vulnerable populations, is analysed in a context of extreme drought in the Cariri region (Ceará state, Brazil). Limitations that prevent the full range of potential PAA benefits are examined as perceived by institutional actors involved with the program, while measures to foster the full potential positive impacts on beneficiaries are discussed. Findings indicate that more consideration of the importance of governance and institutional factors on functioning of food acquisition programs, as well as the importance of the role of climate change on this equation, are essential for program sustainability, especially in a scenario of climate change.

El enfoque de Servicios Ecosistémicos (SE) constituye una herramienta utilizada para abordar problemáticas ambientales. La valoración de SE en términos ecológicos, monetarios o socioculturales es un elemento clave de esta perspectiva. Realizamos una revisión de artículos científicos centrados en SE publicados entre 2005-2017 en revistas de ecología y biología de la conservación, investigando la forma en que se recuperan voces de diferentes actores sociales (AS). Los resultados indican que predominan las valoraciones ecológica y monetaria por sobre la valoración sociocultural, y que esta última se realiza de una manera que consideramos superficial -sin abordar conflictos entre diferentes AS, y con los investigadores seleccionando los SE a valorar. Considerando que los conflictos vinculados con SE están inmersos en contextos sociales complejos, descuidar “dimensiones sociales”, puede llevar a omitir distancias culturales, diferencias de clase, ubicación geográfica, estilo de vida, y esto puede llevar al desarrollo de opciones de gestión inviables o perjudiciales para los AS involucrados.

En este artículo se ha realizado un estudio de la significación de la contaminación en dos conflictos articulados en torno a la cuestión ambiental: Pueblos Unidos y VUDAS- Vecinos Unidos en Defensa de un Ambiente Seguro de Córdoba, Argentina. El sufrimiento ambiental no es experimentado en aislamiento, sino dentro de contextos discursivos y en relaciones de poder. Estos contextos dan forma a los caminos en los cuales la aflicción es vivida y comprendida en cada caso. A partir del análisis de contenido de veinte entrevistas en profundidad concluimos que en los conflictos analizados se construyen dos sentidos opuestos en relación a la contaminación: mientras que en Pueblos Unidos el peligro de enfermedades por contaminación es relativizado, en un contexto de ausencia de otras oportunidades para garantizar la vida, en VUDAS, la contaminación es la estructurante principal de la lucha ya que denuncian su presencia y la enfermedad de los cuerpos.

Os óculos solares surgiram após a Primeira Guerra Mundial e, desde então, são utilizados por grande parte da população como um acessório e como proteção para os olhos. Para investigar o final do ciclo de vida desse produto, elaborou-se um questionário virtual, obtendo-se 765 respostas; complementarmente foram realizadas entrevistas em óticas, lojas especializadas e oficinas de reparos da cidade de Porto Alegre (Brasil). De acordo com os dados coletados, foram selecionados dois óculos solares: modelo A, de polímero termoplástico, e modelo B, de madeira, visando analisar o potencial de reciclabilidade desses produtos. As armações dos modelos foram analisadas sob ótica do design orientado para a desmontagem (DfD) e para a reciclagem (DfR). Foi necessária caracterização de materiais de componentes do modelo A por técnica de FT-IR. As análises apontam que a armação do modelo A, de policarbonato, tem menor impacto na desmontagem, separação e reaproveitamento dos materiais pela indústria de reciclagem mecânica. Apesar de o modelo B ter materiais de origem renovável (madeira), a fabricação da armação por prensagem com resina epóxi compromete a separação dos materiais pós-consumo. Nesse caso, indica-se seu reaproveitamento por reciclagem energética.
