Abstract Monkey mortality in Costa Rica is due, in most cases, to anthropogenic factors, such as deforestation, forest fragmentation, lack of tree connectivity, and tourism development in most coastal areas. The latter factor has caused the death of at least 450 monkeys per year due to electrocution, as a result of the increase in electrical wiring that has arisen in the different regions with urban development. Faced with this threat, proposals have been developed to avoid the danger, such as the construction of appropriate passage infrastructure for monkeys, the placement of insulated wiring, and the protection of electrical transformers. Using the morphometric measurements of the four species of monkeys native to Costa Rica (Alouatta palliata, Ateles geoffroyi, Saimiri oerstedii, and Cebus imitator), a model of safe and functional aerial passages or bridges for them was designed, the foundations of which are discussed in this article.

Resumen La mortalidad de los monos en Costa Rica se debe, en la mayoría de los casos, a factores antropogénicos, como la deforestación, la fragmentación de los bosques, la falta de conectividad arbórea y el desarrollo turístico en la mayoría de las zonas costeras. Este último factor ha provocado la muerte de al menos 450 monos por año debido a la electrocución, a raíz del aumento del cableado eléctrico que ha surgido en las diferentes regiones con desarrollo urbanístico. Ante esta amenaza se han elaborado propuestas para evitar el peligro, como la construcción de infraestructura de paso apropiada para los monos, la colocación de cableado aislado y la protección de los transformadores eléctricos. Utilizando las medidas morfométricas de las cuatro especies de monos nativas de Costa Rica (Alouatta palliata, Ateles geoffroyi, Saimiri oerstedii y Cebus imitator), se diseñó un modelo de pasos aéreos o puentes seguros y funcionales para ellos, cuyos fundamentos se discuten en el presente artículo.

Abstract (Introduction): Bycatch and discards are a socio-environmental concern that threatens the sustainability of marine life and fishing grounds. Approaches to this problem have focused on biological and/or ecological aspects. We considered it necessary to explore the problem from the social dimension and for this purpose we explored social representations. (Objective): The aim of this study is to explore the social representations of bycatch and discards in a group of businessmen and workers in the capture stage of the Argentine industrial fishing activity. We ask how they evaluate bycatch and fishing discards, what are their causes and if they observe possible solutions. (Methodology): Within the framework of a project of the Federal Fishing Council, we conducted focus groups with businessmen, business chambers, SOMU workers and captains of the industrial fishing activity. (Results): The results of the focus groups conducted in 2021 reveal three main causes of this problem. First, the lack of reliable data on actual discard levels raises concerns about sustainability and overfishing. Second, the low utilization of selectivity devices is attributed to their operational inefficiency and possible labour barriers. Finally, economic and organizational pressures, such as company profitability and workers’ salaries, justify the discard of non-target species, exacerbating the problem. (Conclusions): The work contributes to an understanding of the main reasons for bycatch and discards, which is essential to advance solutions. We understand that solutions are not simple and involve a sincere debate among stakeholders.

Resumen (Introducción): Las capturas incidentales y los descartes pesqueros son una preocupación socioambiental que amenaza la sostenibilidad de la vida marina y de los caladeros. Los abordajes a esta problemática estuvieron centrados en aspectos biológicos y ecológicos. Consideramos necesario explorar la problemática desde la dimensión social y para ello, exploramos las representaciones sociales. (Objetivo): El objetivo de este estudio fue explorar las representaciones sobre capturas incidentales y descartes pesqueros en un grupo de empresarios y trabajadores de la etapa de captura de la actividad pesquera industrial argentina, específicamente, cómo evalúan este problema, sus causas y posibles soluciones. (Metodología): En el marco de un proyecto del Consejo Federal Pesquero, se realizaron grupos focales con seis cámaras empresariales y personal jerárquico de empresas asociadas, así como trabajadores del SOMU y capitanes que operan en alta mar. (Resultados): Los resultados de los grupos focales realizados en 2021 revelaron tres principales causas de dicha problemática. Primero, la falta de datos confiables sobre los niveles reales de descarte genera preocupaciones sobre la sostenibilidad y la sobreexplotación. Segundo, la escasa utilización de dispositivos de selectividad se atribuye a su ineficacia operativa y a posibles barreras laborales. Finalmente, las presiones económicas y organizacionales, como la rentabilidad de las empresas y los salarios de los trabajadores, justifican el descarte, exacerbando el problema. (Conclusiones): El trabajo aporta a un entendimiento sobre las razones de la captura incidental y los descarte, esencial para avanzar en soluciones. Entendemos que las soluciones no son simples e implican un sincero debate entre actores.

Abstract (Introduction): Within the framework of the present capitalist system, human beings have become an important polluting agent. Current production and consumption processes do not consider the existence of finite natural resources and a planet incapable of treating the waste that the prevailing way of life generates. Given these circumstances, the study of non-linear models is of interest, which make a more rational use of the waste that the productive activity generates, favoring recycling mechanisms. The phenomenon of recycling becomes particularly relevant in the case of electrical and electronic devices, whose ability to be degraded and metabolized by planet Earth is extremely difficult. (Objective): Evaluate the feasibility of installing and starting a recycling plant for electrical and electronics items in the town of Bahía Blanca (Argentina), during 2021. (Methodology): The conventional method for evaluating investment projects was used, considering technical, legal and economic aspects. (Results): The project is not acceptable according to the profitability intended by the investor. The possibility of financing was also included, which made the project even less profitable, and the sensitivity of the results was measured, finding that the price should be 1.48 % higher than that used in the analysis. (Conclusions): Other alternatives must be explored to make this proposal profitable from an economic and financial point of view.

Resumen (Introducción): En el marco del sistema capitalista vigente, el ser humano se ha transformado en un agente significativo de contaminación. Las dinámicas productivas y de consumo actuales no contemplan la existencia de recursos naturales finitos y de un planeta incapaz de procesar los desperdicios que el modo de vida habitual genera. Dadas estas circunstancias, cobra interés el estudio de modelos no lineales, que hagan un uso más racional de los residuos derivados de la actividad productiva, los cuales favorezcan mecanismos de reciclaje. El fenómeno del reciclaje se vuelve, en particular, relevante para el caso de los artefactos eléctricos y electrónicos; la capacidad del planeta Tierra para degradarlos y metabolizarlos resulta sumamente difícil. (Objetivo): Evaluar la factibilidad de la instalación y puesta en marcha de una planta recicladora de artículos eléctricos y electrónicos en la localidad de Bahía Blanca (Argentina), durante el 2021. (Metodología): Se utilizó la metodología convencional de evaluación de proyectos de inversión, considerando aspectos técnicos, legales y económicos. (Resultados): El proyecto no es aceptable según la rentabilidad pretendida por el inversor. También se incluyó la posibilidad de un financiamiento, lo que hizo que el plan fuera menos rentable aún, y se midió la sensibilidad de los resultados: se halló que el precio debiera ser 1.48 % superior al utilizado en el análisis. (Conclusiones): Se deben explorar otras alternativas para lograr que el proyecto sea rentable desde el punto de vista económico-financiero.

Abstract (Introduction): The current cultivation of trees is insufficient to cover the national demand for wood, in this way small producers become an alternative solution to this situation, since despite having small areas, in the country there are abundant farms with these conditions; However, the current forest management scheme does not meet adequate standards for the incorporation of these small producers. (Objective): To present an adaptive forest management scheme (AFMS) to the needs of the small farmer, in addition, to demonstrate the institutional availability to change according to expert criteria. (Methodology): 1) the factors that influence the decision to adopt an agricultural or forestry production system were identified; 2) a profile of an ideal productive system that met the interests and preferences of the small producer was made, which was compared with the characteristics of agricultural and forestry production; 3) the proposal of an EMFA adjusted to the preferences and interest of the producer was made, which was also compared with the ideal profile; 4) three proposed change actions were presented to experts, obtaining different degrees of possibility of changes in the EMFA. (Results): The discrepancy of the forest management scheme for the cultivation of trees with the perspective that a small producer has on an ideal production system was evidenced, as well as the substantial improvement that an EMFA would have in the valuation of the small producer and the institutional availability to change the EMFA according to the perspective of the small producers. (Conclusions): The adjustment of the forest management scheme allows a greater adoption of the activity by the small producer, but it was recognized that any proposal that is made would be successful only if forest governance makes it more flexible and allows change.

Resumen (Introducción): El cultivo actual de árboles es insuficiente para cubrir la demanda nacional de madera, de este modo, los pequeños productores se tornan como una alternativa de solución ante esta situación, ya que pese a contar con áreas pequeñas, en el país son abundantes las fincas con estas condiciones; sin embargo, el esquema actual de manejo forestal no cumple con estándares adecuados para la incorporación de estos pequeños productores. (Objetivo): Presentar un esquema de manejo forestal adaptativo (EMFA) a las necesidades del pequeño productor, además de evidenciar la disponibilidad institucional al cambio, según el criterio experto. (Metodología): 1) se identificaron los factores que influyen en la decisión de adopción de un sistema productivo agrícola o forestal; 2) se realizó un perfil de un sistema productivo ideal que cumpliera con los intereses y preferencias del pequeño productor, el cual se confrontó con las características de la producción agrícola y forestal; 3) se efectuó la propuesta de un EMFA ajustado a las preferencias e interés del productor, que fue también confrontada con el perfil ideal; 4) se expusieron tres acciones de cambio propuestas ante expertos, obteniendo diferentes grados de posibilidad de cambios en el EMFA. (Resultados): Se evidenció la discrepancia del esquema de manejo forestal para el cultivo de árboles con la perspectiva que un pequeño productor tiene sobre un sistema de producción ideal, asimismo la mejora sustancial que un EMFA tendría en la valoración del pequeño productor y la disponibilidad institucional al cambio del EMFA, según la perspectiva de los pequeños productores. (Conclusiones): El ajuste del esquema de manejo forestal permite una mayor adopción del cultivo de árboles por parte del pequeño productor, pero se reconoció que cualquier propuesta que se realice lograría ser exitosa si la gobernanza forestal flexibiliza y posibilita el cambio.

Abstract (Introduction): Vinasse is generated as a residue in the production of ethanol by fermentation-distillation of molasses/sugar cane juice, at a rate of 13 L/L of ethanol. It is an acid liquid, brown in color, characterized by high mineralization and Chemical Oxygen Demand (COD) values of up to 150 000 mg/L, being highly polluting. (Objective): The objective of this research was to evaluate a vinasse treatment process with hydrogen peroxide as a source of hydroxyl radicals at laboratory scale. (Methodology): The vinasse samples, from different distilleries in the province of Tucumán, were characterized following standardized techniques of Standard Methods. The oxidation tests were carried out with different peroxide/vinasses ratios, in a semi-batch reactor, under ambient conditions, measuring COD as an indicator parameter of the treatment. (Results): After 5 days, an 85 % decrease in COD and an increase in the Biodegradability Index were achieved. The kinetics of the oxidative reaction was first order with respect to COD, with an apparent rate constant of 0.3694 1/day. (Conclusions): Although the COD values allowed by local regulations (250 mg/L) were not reached, the proposed treatment is encouraging due to its simplicity, representing a potential option to the environmental challenge represented by vinaze in Latin America.

Resumen (Introducción): La vinaza se genera como residuo en la producción de etanol por fermentación-destilación de melazas/jugos de caña de azúcar, a razón de 13 L/L de etanol. Es un efluente líquido, ácido caracterizado por una elevada mineralización y valores de demanda química de oxígeno (DQO) de hasta 150 000 mg/L, siendo altamente contaminante. (Objetivo): Ealuar un proceso de tratamiento de vinazas con peróxido de hidrógeno, como fuente de radicales hidroxilos, en escala laboratorio. (Metodología): Las muestras de vinazas, de destilerías de la provincia de Tucumán, se caracterizaron según técnicas normalizadas de Standard Methods. Los ensayos de oxidación se realizaron con distintas relaciones de peróxido/vinaza, en un reactor semibatch, en condiciones ambientales, midiendo DQO como parámetro indicador del tratamiento. (Resultados): Al cabo de cinco días se logró una disminución de DQO del 85 % y un aumento del Índice de Biodegradabilidad. La cinética de la reacción oxidativa fue de primer orden respecto de DQO, con una constante aparente de velocidad de 0.3694 1/día. (Conclusiones): Si bien no se lograron los valores de DQO permitidos por la normativa local (250 mg/L), el tratamiento propuesto es alentador por su simpleza, representando una opción potencial al desafío ambiental que representan las vinazas en América Latina.

Abstract (Introduction): The search for techniques and methods for managing sludge generated during wastewater treatment is necessary to ensure sustainable sanitation in the medium term in Latin America. An interesting approach involves converting sludge into a biosolid usable in agriculture through alkaline sanitization. (Objective): We evaluated this technique’s efficacy and economic and environmental viability for obtaining an agriculturally usable type A biosolid from municipal wastewater treatment plant (WWTP) sludge. (Methodology): To this end, the efficacy in reducing microbiological parameters was experimentally tested at the laboratory scale using quicklime, for anaerobic and aerobic WWTP sludge. The experimental results fed a benefit/cost analysis model and a life cycle assessment. (Results): It was confirmed that applying a 40 % lime dose allowed the obtention of a type A biosolid with non-detectable concentrations of pathogenic microorganisms, which remained in that condition for more than 30 days. Additionally, the benefit/cost and life cycle analyses concluded that this option would be more attractive than sludge disposal in a landfill, due to the corresponding savings in chemical compounds (fertilizers, agricultural lime). (Conclusions): Therefore, alkaline sanitization can be considered suitable for WWTP sludge management. Its application on a larger scale should be further investigated in the country and the Latin-American region, considering the risk associated to the presence of heavy metals too.

Resumen (Introducción): La búsqueda de técnicas y modelos de gestión del lodo generado durante el tratamiento de las aguas residuales es necesaria para garantizar un saneamiento sostenible a mediano plazo en América Latina. Una vía interesante consiste en convertir el lodo en un biosólido aprovechable en la agricultura por medio de la higienización alcalina. (Objetivo): Se evaluó la eficacia y la viabilidad económica y ambiental de esta técnica para la obtención de un biosólido tipo A aprovechable en la agricultura a partir de lodo de planta de tratamiento de aguas residuales (PTAR) ordinaria. (Metodología): Para ello se probó experimentalmente en escala de laboratorio la eficacia en el decaimiento de parámetros microbiológicos higienizados con cal viva, usando lodo anaeróbico y aeróbico de PTAR. Los resultados experimentales alimentaron un modelo de análisis de beneficio/costo y de ciclo de vida. (Resultados): Pudo corroborarse que la aplicación de dosis de cal de 40 % permitió obtener un biosólido tipo A con concentraciones de microorganismos patógenos no detectables, lo cual se mantuvo en esa condición por más de 30 días. Además, el análisis de beneficio/costo y de ciclo de vida permitieron concluir que esta opción sería más atractiva que la disposición del lodo en un relleno sanitario, debido al ahorro correspondiente en compuestos químicos (fertilizantes o cal agrícola) derivado de su aprovechamiento. (Conclusiones): Por lo tanto, la técnica de higienización alcalina puede considerarse como adecuada para la gestión del lodo de PTAR y su aplicación a mayor escala debe investigarse en mayor detalle en el país y la región latinoamericana, considerando también el riesgo de presencia de metales pesados en este subproducto.

Abstract (Introduction): In the removal of chromium (VI) from tannery wastewater, physicochemical methods are the most used. However, these require high operating costs, and worse still, generate secondary pollutants that again require complementary treatments for their elimination. Given this, the applicability of vegetable organic biomass (VOB) emerges as an environmental alternative based on: the simplicity of its obtaining, the reduction as waste, it does not generate secondary pollutants and, above all, it removes chromium (VI). (Objective): Use VOB waste in an aerobic sequential biological reactor (SBR) for the removal of chromium (VI) in the treatment of tannery wastewater. (Methodology): 3 aerobic SBR systems were implemented; 2 controls (SBR1 and SBR2) and 1 study subject (SBR+VOB). Each system was fed with tannery wastewater (18 L) and connected to an aeration mechanism (12.7 L/min). The bacterial inoculum, a fundamental part of an SBR system, was gained from the selective culture of chromium (VI) reducing bacteria (RBCrVI) taken from the wastewater under study, and integrated into SBR2 and SBR+VOB at 0.6 g/L. The VOB was obtained from Stenotaphrum secundatum residues, fragmented, sieved, sterilized and integrated into the SBR+VOB at 1.5 g/L. (Results): The SBR+VOB system achieved the highest percentage of chromium (VI) removal (93 %), followed by SBR2 (80.1 %), and finally SBR1 (2.8 %). With respect to COD and TSS, the statistical test (Tukey) showed that there was no significant difference between the system under study and the controls, recording COD removal percentages ranging from 87.8 % to 88.4 %, and TSS ranging from 63.8 % to 69.2 %. (Conclusions): The viability of using VOB waste to remove chromium (VI) in the treatment of tannery wastewater has been evidenced. The results of this research create a promising panorama to mitigate the effects derived from inadequate management of tannery wastewater and organic solid waste.

Resumen (Introducción): En la remoción de cromo (VI) de aguas residuales de curtiembre, los métodos fisicoquímicos son los más empleados. Sin embargo, estos demandan altos costos operativos y, peor aún, generan contaminantes secundarios que nuevamente requieren tratamientos complementarios para su eliminación. Ante ello, la aplicabilidad de la biomasa orgánica vegetal (BOV) emerge como una alternativa ambiental sobre la base de: la simplicidad de su obtención, la disminución como residuo, no genera contaminantes secundarios y, sobre todo, de remover cromo (VI). (Objetivo): Usar residuos de BOV en un reactor biológico secuencial (RBS) aerobio, para la remoción de cromo (VI) en el tratamiento de agua residual de curtiembre. (Metodología): Se implementaron 3 sistemas RBS aerobios; 2 controles (RBS1 y RBS2) y 1 materia de estudio (RBS+BOV). Cada sistema fue alimentado con agua residual de curtiembre (18 L) y conectado a un mecanismo de aireación (12.7 L/ min). El inóculo bacteriano, parte fundamental de un sistema RBS, se obtuvo a partir del cultivo selectivo de bacterias reductoras de cromo (VI) (BRCrVI), tomadas del agua residual en estudio e integradas al RBS2 y RBS+BOV a 0.6 g/L. La BOV se obtuvo de residuos de Stenotaphrum secundatum, fragmentado, tamizado, esterilizado e integrado al RBS+BOV a 1.5 g/L. (Resultados): El sistema SRB+BOV alcanzó el mayor porcentaje de remoción de cromo (VI) (93 %), seguido por SBR2 (80.1 %) y, por último, de RBS1 (2.8 %). Con respecto a la DQO y SST, la prueba estadística (Tukey) arrojó que no había diferencia significativa entre el sistema en estudio y los controles, por lo que registró porcentajes de remoción de DQO que van de 87.8 % a 88.4 % y SST que van de 63.8 % a 69.2 %. (Conclusiones): Se ha evidenciado la viabilidad del aprovechamiento de residuos de BOV para remover cromo (VI) en el tratamiento de agua residual de curtiembre. Los resultados de la presente investigación crean un panorama prometedor para mitigar los efectos derivados de la inadecuada gestión de las aguas residuales de curtiembre y de los residuos sólidos orgánicos.

Abstract The critical importance of wetland ecosystems is highlighted, as they provide essential services such as regulating the hydrological cycle, flood control, and filtering pollutants. Globally, 64 % of wetlands have been lost since 1970, with Asia being the most affected region. Agricultural expansion, urban development, and aquaculture are some of the main drivers of the degradation of these ecosystems, particularly mangroves, which play a key role in climate change mitigation. In Costa Rica, wetlands under inventory represent 6.01 % of the national territory, and although the country has made progress in their protection, with 49 % of wetlands falling under some category of protected wild area, challenges remain, such as agricultural expansion, livestock farming, and sedimentation. At the international level, the Ramsar Convention has been key to wetland conservation efforts, with over 2.57 million km2 protected. However, additional efforts are needed to mitigate the threats to these ecosystems, especially in the context of climate change.

Resumen Se resalta la importancia crítica de los ecosistemas de humedales, que proporcionan servicios esenciales, como la regulación del ciclo hidrológico, el control de inundaciones y la filtración de contaminantes. En el nivel global, se ha perdido un 64 % de los humedales desde 1970, con Asia siendo la región más afectada. La expansión agrícola, el desarrollo urbano y la acuicultura son algunas de las principales causas de la degradación de estos ecosistemas, especialmente de los manglares, que cumplen una función clave en la mitigación del cambio climático. En Costa Rica, los humedales bajo inventario representan el 6.01 % del territorio nacional, y aunque el país ha avanzado en su protección, con el 49 % de los humedales bajo alguna categoría de área silvestre protegida, persisten desafíos, como la expansión agrícola, la ganadería y la sedimentación. En el plano mundial, la Convención Ramsar ha sido clave en los esfuerzos de conservación de humedales, con más de 2.57 millones km2 protegidos. Sin embargo, se necesitan esfuerzos adicionales para mitigar las amenazas a estos ecosistemas, especialmente en el contexto del cambio climático.

Abstract Introduction Lupus nephritis (LN) affects up to 50% of patients with systemic lupus erythematosus (SLE) and may lead to kidney failure and require kidney transplantation (KT). Results compared to KT from other causes are controversial, and we aimed to assess the clinical course, complications, and survival of LN patients undergoing KT. Methodology Retrospective cohort of 99 KT due to LN from 1977 to 2023 at a single center, divided into two groups according to the immunosuppression period: G1 (before 2009) and G2 (from 2009 onwards). Clinical and demographic characteristics, as well as clinical evolution, were compared. Results Patients were predominantly white (65.9%), female (86.9%), in their first KT (83.8%). The median age was 20.0 (11.5–25.0) years at SLE diagnosis, and 30.0 (23.0–40.0) years at KT. Renal graft biopsy was indicated in 46% of patients, with rejection observed in 23%, and LN recurrence in 5%. When assessing the two distinct periods of standard immunosuppression, there was no difference in median glomerular filtration rate and proteinuria at 1 and 5 years, nor in 5-year survival. Throughout follow-up, 37.4% of patients lost their graft, and 13% died with a functioning graft. No graft loss was attributed to LN recurrence. Conclusion KT is a successful treatment for LN, with graft survival rates similar to those of transplants from other causes. LN recurrence was not associated with renal graft loss. (LN 50 (SLE .

Resumo Introdução A nefrite lúpica (NL) afeta até 50% dos pacientes com lúpus eritematoso sistêmico (LES) e pode levar à falência renal e necessidade de transplante renal (TR). Os resultados em comparação à TR por outras causas são controversos, e visamos avaliar evolução clínica, complicações e sobrevida de pacientes com NL submetidos a TR. Metodologia Coorte retrospectiva de 99 TR por NL de 1977 a 2023 em um único centro, divididos em dois grupos conforme o período de imunossupressão: G1 (antes de 2009) e G2 (a partir de 2009). As características clínicas, demográficas e evolução clínica foram comparadas. Resultados Pacientes eram na maioria brancos (65,9%), sexo feminino (86,9%), no primeiro TR (83,8%). A idade mediana foi 20,0 (11,5–25,0) anos no diagnóstico de LES e 30,0 (23,0–40,0) anos no TR. Biópsia do enxerto renal foi indicada para 46% dos pacientes, com rejeição em 23% e recorrência de NL em 5%. Avaliando os dois períodos distintos de imunossupressão padrão, não houve diferença na mediana de taxa de filtração glomerular e de proteinúria em 1 ano e em 5 anos, nem da sobrevida em 5 anos. Em todo o acompanhamento, 37,4% dos pacientes perderam o enxerto e 13% morreram com enxerto funcionante. Nenhuma perda foi atribuída à recorrência de NL. Conclusão TR é um tratamento bem-sucedido na NL, com taxas de sobrevida do enxerto semelhantes às de transplantes por outras causas. A recorrência de NL não esteve associada à perda do enxerto renal.

Resumo Neste artigo, é abordada uma experiência de valorização cultural e ambiental relacionada ao turismo na metrópole do Ruhr, uma região industrial alemã com longa tradição de mineração de carvão e produção de aço que, até o final do século passado, não tinha grandes atrações turísticas ou sequer considerava tê-las. Para isso, enfatiza-se o papel do patrimônio industrial e sua conexão com a recuperação ecológica do rio Emscher, que tem sido o carro-chefe do bem-sucedido desenvolvimento turístico da região nas últimas décadas.

Abstract This article addresses an experience of cultural and environmental valorization related to tourism in the Ruhr metropolis, a German industrial region with a long tradition in coal mining and steel production that, until the end of the past century, had neither major tourist attractions nor any intention of developing them. To this end, the article emphasizes the role of industrial heritage, which has been the flagship of the region’s successful tourism development in recent decades, and its connection with the ecological recovery of the Emscher River. However, the main objective of the article is to show that industrial tourism can drive other dimensions of tourism that broaden the scope of regional opportunities, particularly in industrial areas like the Ruhr metropolis. metropolis century them heritage regions s decades River However opportunities

Resumo Este artigo oferece uma alternativa de recorte metodológico para o campo da Smart city, partindo de uma revisão bibliográfica temporal e análise empírica da Smart city Konza Technopolis (Quênia), da smartificação de São Paulo (SP/Brasil), e da Smart city Laguna (CE/Brasil). As experiências Smart city desenvolvem-se desde o final de 1990, detendo maior expressividade no espaço urbano a partir dos anos 2010, concomitantemente ao aumento das pesquisas a seu respeito.

Abstract This article offers an alternative methodological framework for the smart city field, starting from a chronological literature review and empirical analysis of the smart city Konza Technopolis (Kenya), the smartification of São Paulo (State of São Paulo, Brazil), and the Smart City Laguna (State of Ceará, Brazil). Smart city experiences have been developed since the late 1990s, with greater expressiveness in the urban space from the 2010s onwards, concomitantly with an increase in the number of studies about the theme. Currently, the theme demonstrates a high level of discussion and maturity. Given its breadth, an analytical focus is necessary to address the particularities related to the three categories presented here: (1) smart cities developed from scratch; (2) initiatives aimed at consolidated cities; and (3) real estate developments. field Kenya, Kenya , (Kenya) State Brazil, Brazil Brazil) Ceará Brazil. . 1990s s onwards Currently maturity breadth here 1 (1 scratch 2 (2 3 (3 developments (Kenya (
