Concrete production is characterized by a significant demand for energy and raw materials. The construction, maintenance, and demolition of engineering works cause excessive polluting waste that requires costly disposal. For this reason, alternative reusable materials that improve the mechanical properties of concrete, such as fly ash, are currently being investigated as an effective solution to reduce problems related to environmental impact. This paper analyzed 80 articles indexed in different databases such as ScienceDirect, IOPscience, Scielo, Ebsco, Scopus, SpringerLink, ProQuest, Dialnet, and Semanticscholar, which were not older than seven years since publication, to conduct an updated systematic review of the use, effect, and influence of fly ash on concrete. The methodologies and designs used to obtain the optimum percentages of 5, 10, and 15% were reviewed, analyzing mainly the results obtained when fly ash is used in concrete. Finally, according to the review carried out, it was concluded that fly ashes improve the mechanical and physical characteristics of concrete, and that the optimum dosage is 10% in substitution of ordinary Portland cement applied in simple concrete.

RESUMO: A contaminação do solo atua como um dos principais problemas no que se refere ao destino inadequado dos resíduos sólidos. Considerando esse processo, o estudo buscou verificar a qualidade ambiental do solo da área sob o aterro controlado do município de Corrente-PI. Através de visita in loco buscou-se identificar os possíveis meios de contaminação do solo, avaliando a disposição dos resíduos, a topografia do local e verificação das técnicas de proteção ao solo/ambiente. No que se refere à disposição dos resíduos sólidos do município identifica-se como irregular, possivelmente provocando a contaminação do solo por não executar o tratamento prévio adequado dos resíduos. Tendo em destaque o aspecto topográfico da área no qual observou-se o relevo suave, de modo ao qual possibilita minimizar o processo de erosão. Diante dos fatores que se encontram irregular na área sob o aterro controlado alguns visam à utilização de um planejamento integral na gestão dos resíduos sólidos no qual se encontram em estado de deficiência na destinação final de tais resíduos, visando promover como subsidio para minimizar possíveis meios de contaminação do solo. A identificação e monitoramento dos resíduos que são depositados na área podem ser realizados de maneira que estabeleça um controle que possa intervir na contaminação do solo na área, mediante diagnóstico detalhado visando os riscos que os resíduos podem causar e possivelmente uma investigação confirmatória dos possíveis fatores que alteram a qualidade do solo. PALAVRAS-CHAVE: Resíduos Sólidos; Impacto Ambiental; Qualidade Ambiental. ABSTRACT: Soil contamination acts as a major problem that stands out with regard to the inadequate disposal of solid waste. Thus, the study looked at the environmental quality of the soil of the area under the landfill in the municipality of Corrente-PI. Through business in loco sought to identify potential soil contamination means of evaluating the disposal of waste, local topography and verification of protection techniques to the ground/environment. As regards the disposal of municipal solid waste is identified as irregular possibly causing contamination of the soil not to perform the appropriate pretreatment of the residues. In highlight the topographical feature area in which there was a gentle slope, so which permits minimizing soil erosion process and possibly facilitate the maintenance of components of the drainage system, prevents the growth of possible contaminating factors from soil. On the factors that are irregular in the area under the landfill controlled some aimed at the use of a comprehensive planning in solid waste management in which they are in a state of deficiency in the final disposal of such waste, to promote as a subsidy to minimize possible means of soil contamination. The identification and monitoring of waste that is deposited in the area can be performed in view of a control that can intervene in the soil contamination in the area, through detailed diagnosis targeting the risks that waste can cause and possibly a confirmatory investigation of possible factors that alter soil quality. KEYWORDS: Solid Waste; Environmental Impact; Environmental Quality.

RESUMO: O presente estudo teve como objetivo analisar os estudos ambientais realizados em Caxias - MA. O trabalho envolveu o levantamento descritivo das principais metodologias de avaliação de impacto ambiental utilizada pelos empreendedores caxienses, verificando a conformidade das principais variáveis de caráter ambiental com a legislação brasileira vigente. A pesquisa do tipo documental constitui na análise dos Estudos Ambientais (EA) disponibilizados na Secretária Municipal de Meio Ambiente e Preservação dos Recursos Naturais – SEMUMA, foram publicados 92 estudos ambientais nos últimos cinco anos (2010 - 2014). As varáveis do estudo foram: categorização dos estudos ambientais, ano de elaboração do estudo, responsáveis pela elaboração do estudo (equipe técnica, pessoa física ou jurídica), empreendedor, tipo de empreendimento, técnica de avaliação (metodologia de mensuração do impacto ambiental) e a conformidade dos estudos com a legislação CONAMA. Os resultados finais apontam que o Plano de Controle Ambiental (PCA) é utilizado como estudo ambiental para o licenciamento de todas as atividades modificadoras dos recursos naturais. Apontam ainda que esses estudos utilizam como metodologia de Avaliação de Impacto Ambiental (AIA) o Check-list. Além do mais, a SEMUMA não utiliza nenhum termo de referências para os estudos ambientais elaborados nos processos de licenciamento ambiental. Por isso, não existe um método específico para ser utilizado em cada tipo de empreendimento, nem mesmo uma verificação da qualidade das informações apresentadas pelos estudos, que demostraram uma moderada conformidade com a legislação do Conselho Nacional do Meio Ambiente – CONAMA. Palavras-chave: Licenciamento Ambiental, Impacto Ambiental, Meio Ambiente. ABSTRACT: This objective was to analyze the environmental studies in Caxias, Maranhão. The work involved the descriptive survey of the main methodologies of environmental impact assessment used by caxienses entrepreneurs, checking compliance of the main environmental character variables with the current Brazilian legislation. The documentary type of research is the analysis of Environmental Studies (ES) available at SEMUMA – a Government Agency in charge of environment supervision in Caxias – 92 environmental studies of the period 2010-2014 were analyzed. The main research variables were: categorization of environmental studies, year of preparation of the study, responsible for drafting the study (technical team, individual or legal entity), entrepreneur, enterprise type, valuation technique (measurement methodology of environmental impact) and as to whether studies with CONAMA legislation. The final results show that the Environmental Control Plan (ECP) is used as environmental study for the licensing of all modifier activities of natural resources. Also indicate that these studies use as the Environmental Impact Assessment (EIA) methodology the Checklist. Moreover, the SEMUMA does not use any term of reference for the environmental studies carried out in the environmental licensing process. Therefore, there is no specific method to be used in each type of enterprise, not even for checking the quality of information provided by studies that showed a moderate line with the current CONAMA legislation. Keywords: Environmental Licensing, Environmental Impact, Environment.

Introducción: el impacto ambiental negativo generado por la producción excesiva y la eliminación irresponsable de plásticos es alarmante a la actualidad. Objetivo: describir la influencia de los micro y nanos plásticos en la salud humana. Método: se realizó una búsqueda en diferentes plataformas, usando las palabras clave: “micro and nanoplastics” or “environmental impact” or “influence on health” and “microplastics and health” or “plastic waste” or “waste disposal”. Resultados: los micro plásticos y nano plásticos en la actualidad sí representan un riesgo ambiental evidente, y sobre todo para la salud humana puesto que se puede encontrar en diferentes partes del organismo. Los micro y nano plásticos se encuentran actualmente en casi todo y ocasionan problemas de salud evidentes, por tanto, es indispensable que la contaminación con plásticos se frene y que los responsables establezcan estrategias que permitan eliminar los desechos de forma responsable precautelando la salud y el bienestar de los seres humanos. Conclusiones: es necesario que la evaluación de la repercusión en la salud se aborde de manera amplia puesto que las afecciones dependerán de varios factores como la fuente de origen, la cantidad, el tipo y la etapa del ciclo de los plásticos en la que se evalúe los efectos, además se debe de considerar el medio de exposición a las sustancias químicas para poder determinar factores de riesgo, posibles consecuencias y medidas preventivas en salud pública.

In the Ecuadorian context, cooling technologies play a critical role in the operation of thermoelectric power plants. These technologies are essential to maintain the efficiency and reliability of power generation plants, which can use a variety of methods to cool their systems. Cooling towers are becoming a common option in Ecuador, allowing heat to be dissipated through the evaporation of hot water. In addition, heat exchangers play an important role in transferring heat from one fluid to another, contributing to the energy efficiency of power plants. However, the country also faces challenges related to the availability of water resources and environmental sustainability. The use of cooling water can raise environmental concerns, especially in a country with rich biodiversity and high dependence on natural resources. Therefore, this paper looks at the experiences of operators and finds that factors such as resource availability, environmental regulations and operational efficiency need to be carefully considered when selecting cooling technologies in Ecuador. Cooling solutions require a balanced approach that ensures reliable and efficient power generation while minimizing environmental impact and protecting the country's unique biodiversity.

A new construction method called steel framing reduces waste and waste generated, however, in most developed countries this method is being replaced by panel construction. For its part, made of light steel, cold formed, galvanized and covered with cement panels on the outside and OSB vinyl coating, Steel Framing is based on galvanized steel profiles that make up the shape and supporting structure of the home. This construction system is lightweight and allows any type of exterior and interior finish; It is sustainable, causes less impact on the environment and provides buildings with new habitability and energy saving characteristics, using better construction technologies in terms of safety, durability, quality and thermal comfort. It has been shown that the thermal behavior of the Steel Framing construction system can reach conditions similar to those of masonry and adequate insulation levels can be determined through modulation, giving greater resistance to the panels, resulting in lower heights bending for vertical posts. Insulating materials are placed on walls and mezzanines to limit the passage of noise and heat/cold. [ABSTRACT FROM AUTHOR]

Weed management systems have been of great importance for agriculture. These can be carried out in various ways, the important thing is to obtain a good control with those measures that are most economical and at the same time practicable. A study was carried out to evaluate the environmental and economic impact of two weed control methods. It was conducted in commercial production areas of the sugar cane farm "Vitalio Acuña" belonging to the sugar mill Dos Ríos, of the Santiago de Cuba province. The total application of preemergent herbicide and mulching with sugarcane trash were studied in a split-plot design with three replications. Weed coverage was determined 30, 60 and 90 days after the treatments were carried out, in addition, the economic expenses incurred were calculated and the pollutant load into the atmosphere was determined. At 90 days, the lowest percentage of weed coverage was obtained in the area of mulching with sugarcane trash with significant differences. The weed control method that had the best performance from the control, environmental and economic point of view was the mulching with sugarcane trash. [ABSTRACT FROM AUTHOR]

Objetivo: Coletar e analisar dados sobre os fatores de riscos sanitários e seus agravos nas marisqueiras de uma praia do litoral sul de Pernambuco. Métodos: Foi realizado um estudo descritivo transversal com dados de um questionário presencial aplicado em mulheres marisqueiras, entre outubro de 2022 e março de 2023, e analisados pelo programa Excel 2021. Foi realizada a análise de água qualitativa e quantitativa dos coliformes fecais, totais e Escherichia coli do rio Maracaípe e da rede de abastecimento local, ambos pelo método de Múltiplos Tubos. Resultados: Foram avaliadas pescadoras artesanais quanto a sua condição de saúde, dentre as quais 60% referem sintomas como diarreia, náusea e vômito correlacionados a parasitose/bacteriose; destas, 44,44% realizam a higienização dos alimentos apenas com água. Na análise da água, revelou-se a presença do grupo coliformes no rio Maracaípe, inferindo que as amostras não atendem aos padrões estabelecidos pela legislação vigente conforme a portaria GM/ MS No 888 de 04 de maio de 2021, que define os padrões de potabilidade de água para consumo humano. Conclusão: O estudo verificou que as marisqueiras se encontram em condições precárias de saneamento básico, carência de serviços de assistência à saúde e há ainda risco de doenças de transmissão de veiculação hídrica visto que a água e os mariscos coletados são ingeridos pela população.

[Introducción]: El programa Estado Verde es un instrumento de acreditación creado por el Ministerio del Medio Ambiente de Chile para que las instituciones públicas del país, de forma voluntaria, puedan desarrollar una gestión ambiental en sus dependencias. El programa busca, entre sus principales fines, fomentar el desenvolvimiento de hábitos ambientales en las personas funcionarias públicas, mediante la educación ambiental. [Objetivo]: Determinar si las campañas educacionales y comunicacionales que promueve el programa han generado cambios en los hábitos y las conductas ambientales del personal público. [Metodología]: Se utilizó el método combinado y para ello se elaboró una encuesta, sobre un universo de 25 000 personas funcionarias. Se obtuvo una muestra de 270 casos, con un nivel de confianza del 90 % y de error de 5 %. Asimismo, se aplicaron 15 entrevistas en profundidad. Los resultados se analizaron por separado y luego se efectuó un análisis cruzado. [Resultados]: Las personas funcionarias reconocen cambios de hábitos favorables para el cuidado ambiental en sus instituciones, aunque estos no son generalizados. [Conclusiones]: Si bien el programa Estado Verde genera cambios de hábitos y conductas en el personal público, requiere un reforzamiento en el fomento de sus estrategias educativas y de modificaciones en algunas exigencias, para un pleno cumplimiento de su objetivo en materia de educación ambiental no formal. Asimismo, los hallazgos pueden ser útiles para que los Estados latinoamericanos adopten acciones proambientales en el funcionamiento administrativo de sus instituciones públicas

RESUMO A redução no consumo de carne tem sido apontada como uma possibilidade de incentivar padrões sustentáveis de consumo e produção na atualidade. Nesse contexto, objetivou-se investigar o que motiva os flexitarianos a reduzir o consumo de carne no Brasil, bem como categorizar os flexitarianos em grupos distintos, considerando a frequência em que a carne é consumida. Para atingir os respondentes, utilizou-se a técnica de amostragem snowball sampling, sendo o questionário disponibilizado pela plataforma Google Docs. A coleta de dados aconteceu no mês de novembro de 2022 e obteve-se um total de 275 respostas. Como resultado identificou-se a prevalência do público, em sua maioria, feminino, solteiro, com elevada escolaridade e renda média de R$ 5.743,50. Além disso, foram categorizados três segmentos de flexitarianos: pouco reflexivos (28,7%); reflexivos (49,9%) e muito reflexivos (21,5%). Os três principais motivos para reduzir o consumo de carne mostraram sobreposição entre os segmentos de flexitarianos, sendo a saudabilidade e redução do impacto ambiental unânime entre os três grupos. Conclui-se que, além da saudabilidade e preocupação com o meio ambiente, o bem-estar animal está no centro das preocupações quando da redução do consumo de carnes, especialmente pelo segmento de flexitarianos muito reflexivos.

RESUMO Licença Social para Operar - LSO é um conceito utilizado tanto como mecanismo estratégico de empresas, para obter aceitação de seus empreendimentos, quanto como elemento de reivindicação por parte de movimentos sociais que os confrontam. Este trabalho analisa posicionamentos públicos feitos sobre o projeto Mina Guaíba, no Rio Grande Sul. Foram identificados os posicionamentos no processo de licenciamento e em audiências públicas, e analisados 36 textos de portais da internet e 8 trabalhos acadêmicos. Os posicionamentos foram analisados de acordo com elementos encontrados na literatura, traçando paralelos com os posicionamentos expostos e os fatos descritos sobre a Mina Guaíba. Foi possível concluir que existem importantes relações entre os posicionamentos públicos sobre o projeto da Mina Guaíba e as questões analisadas em estudos empíricos sobre a obtenção da LSO em nível internacional. Problemas como o economicismo retórico em prol dos empreendimentos, a manipulação dos espaços de consulta, as omissões em relação aos reais impactos ambientais dos projetos e a crise de confiança vivenciada pelo setor de mineração se fazem constantes em ambos os casos. O artigo contribui com o debate sobre LSO ao apontar a relevância das ações organizadas por movimentos sociais e organizações ambientalistas no sentido de conscientização social.

the increase in waste generation and constant growth requires quantification of emissions in order to assess the problem and contribute to its mitigation. The study evaluated the impact of non-hazardous waste through organic and inorganic indicators, such as annual tons of paper and cardboard, plastics, ferrous metal, food waste, garden and wood, for three base scenarios (BS) for the period 2016-2018, a reference scenario (integration of the base scenarios) and a futuristic scenario determined by the increase in production. These scenarios were built based on the availability of information from the safety and environmental sector of the industry to calculate CO2-eq (Carbon Dioxide Equivalent) using the GHG-MRS tool, based on pre-defined parameters adapted to the availability of information and the conditions of the case study. The 2016 EB estimated 60 t/a/CO2-eq, the 2017 EB presented 46 t/a/CO2-eq, the 2018 EB generated 14 t/a/CO2-eq, while the reference scenario determined 60 t/a/CO2-eq. The data provide a prospective vision for decision-making in a petrochemical industry in southern Tamaulipas, contributing to the problem of increasing waste from a specific sector with regional implications.

The houses financed through MIDUVI, as is the case of the T8 house, are designed for a family of only five members at most, that is, mother, father and three children; However, what happens as time goes by is that older children often have a partner and want to start a new home; which is a very recurrent situation in Latin American culture. With this background, it is essential to provide an alternative so that the T8-type house can have efficient vertical growth, through a second floor, which can be converted into a second home to accommodate the members of the extended family. Therefore, the primary objective of this document is "Determine the feasibility of progressive vertical growth in social housing - MIDUVI type T8 with traditional materials for the improvement of spatial conditions and habitability of users and the reduction of the environmental impact produced by conventional construction in the Portoviejo canton": for which the methodology used was of a mixed type, through a user survey and review of bibliographical bases. In the same way, an analysis of the essential materials for the proposed construction process was carried out, as well as the plans and their general details. From all this study it was obtained as a conclusion that the vast majority of respondents who determine outstanding benefits in construction with traditional materials such as cane and wood, such as comfort, sustainability and economy, which makes it a major socioeconomic constructive option. feasibility than conventional construction based on reinforced concrete.

The problem of household solid waste management is a growing concern throughout the world due to the constant increase in the urban population and the generation of garbage. The purpose of this article is to analyze the amount of solid waste generated by homes, with the objective of evaluating the eco-efficient management of household solid waste for the sustainable development of the Quevedo Canton, Guayacán parish, seeking to promote an environmental culture and reduce the levels pollution caused by poor waste management. This was achieved through the proper management of organic and inorganic waste. Taking into consideration 116 households as a sample, implementing questionnaires based on the liker scale with a confidence level of 95% and a margin of error of 5% in a quantitative manner, where the daily generation will be 1.30 kg/hb/day. Once the results were obtained, we worked on the construction of the decision tree with the main purpose of identifying the characteristic with the greatest impact on each home by manipulating the Python programming language. In this sense, the eco-efficient management of household organic waste is presented as an alternative with a higher percentage promoting sustainable development where the importance in the social and economic development of households was highlighted by carrying out an updated diagnosis on the levels of knowledge and participation showing an average model accuracy of approximately 89.6%, based on the selected features.

The present investigation is oriented to determine the potential of solar energy as a renewable source for a swine center established in the "El Guayabal" University Farm, belonging to the Agrarian University of Havana, Cuba. For this, the number of animals is considered, as well as the movement of the herd, which would make it possible to determine the energy demand, based on the diagnosis of the energy carriers existing in the scenario. Among the main results obtained, it was evidenced that for the existing conditions, it is pertinent to introduce photovoltaic solar energy technology as a renewable source for driving the electric motor of the mill, the water pump and lighting, which implies an initial investment of 645 500 peso (25 820 USD). On the other hand, the introduction of a solar heater is viable, for the sanitation actions of the workers of the pig center, with the budget required for the acquisition of this technology being 9 650 peso (386 USD). The introduction of both technologies contributes directly to caring for the environment by stopping the emission of CO2 and other greenhouse gases into the atmosphere and its corresponding negative impact on the environment. Finally, it is evident that, with only the commercialization of the pigs to the carcass of the first group, the total amount required for the acquisition of the photovoltaic system and the solar heater is recovered and it is possible to obtain a benefit that amounts to 478 850 pesos (19 154 USD), this element demonstrates the economic feasibility of this investment.

The use of certain techniques to impel the production brings countless affectations to the ecosystem; this happens for the lack of a true environmental culture. This work has as objective to evaluate the level of knowledge of managers, researchers, specialists and agricultural machinery personnel in the application of farming technologies and its incidence in the environment. For it was elaborated a survey directed to the checking of the environmental education, in order to evaluate the knowledge on how the agricultural machinery impact in the environment and which measures can take to diminish or to avoid it. The results indicate that although exists a general culture on the concept of environmental impact, there are not wholly knowledge aboutits effects. The entirety of those interviewed knows the different methods of soil farming and having in account its characteristics, which are the most aggressive, however 100 % of those interviewed revealed that in its radius faction it is applied the traditional technology of soil farming and all coincided that becomes necessary that before introducing a new technology in the productive process, it is necessary to evaluate its environmental impact.

This article addresses the need to use Strategic Environmental Assessment (SEA) as a tool to assess the environmental impacts resulting from the implementation of the Bioceanic Route in Mato Grosso do Sul, also known as the Bioceanic Corridor or the Latin American Integration Route (RILA). The main objective is to examine the lack of coordinated action in predicting the environmental impacts of this route and identify the best legal instruments within the Brazilian system to conduct this assessment. The methodology used includes literature review, analysis of documentary data from public agencies, and investigation of relevant legislation on the subject. The Brazilian development model, which prioritizes economic interests, requires the protection of other issues, especially environmental ones. Decision-making on public policies should be guided by the principle of sustainable development, involving participation and awareness of the community. The article examines different instruments of Environmental Impact Assessment (EIA), such as the Preliminary Environmental Impact Study (EIS) and its Environmental Impact Report, as well as Strategic and Integrated Environmental Assessments. As a strategy to address the potential negative consequences of the Bioceanic Route, the implementation of SEA is proposed as a policy, promoting greater government transparency and connection between the economy, quality of life, and the environment. The authors argue that, in the case of the Bioceanic Route, SEA is the most suitable instrument to assess the environmental and social impacts resulting from this undertaking. In summary, the implementation of the Bioceanic Route in Mato Grosso do Sul requires a comprehensive analysis of environmental impacts and the adoption of appropriate measures to mitigate potential negative consequences. The use of Strategic Environmental Assessment (SEA) emerges as a promising solution to evaluate and manage the effects of this route, ensuring sustainable and balanced development for the region.

El objetivo de la investigación es comparar las prácticas del doble rol de la responsabilidad social empresarial de los medios de comunicación en Puno en los años 2015 y 2021. En cuanto a la metodología corresponde a una investigación descriptiva comparativa de ocho medios de comunicación de Puno (Perú) que además de ser los de mayor audiencia, desarrollan prácticas de responsabilidad social desde un doble rol que considera aspectos de: Responsabilidad Social Empresarial específico del sector de los medios y Responsabilidad Social Empresarial común a todos los sectores. El instrumento utilizado fue el propuesto por la Fundación Nuevo Periodismo Iberoamericano (2008), diligenciado a los directivos de los medios objeto de estudio. Los resultados muestran respecto al primer rol, que los medios, producto de la crisis sanitaria han generado contenidos prioritariamente sobre la pandemia mundial por la covid-19; asimismo, se evidencia que, dentro de los aspectos específicos del sector de los medios, tanto en el año 2015 y 2021 se mantiene una preeminencia por la “Libertad de expresión”. Sobre el segundo rol, también prevaleció el tema salud, hay concordancia que en los años 2015 y 2021 predominaron temáticas de impacto ambiental, derechos humanos e impacto en la sociedad. Se concluye que la dualidad de roles ha acentuado en la agenda sobre el SARS-CoV-2 en el año 2021, por otro lado, se consolidan prácticas o acciones de responsabilidad social del sector de los medios en Puno relativamente más estable en el segundo rol.

En esta investigación se analiza el avance de la regulación económica e impacto ambiental de las concesiones cupríferas de la gran minería, para ello se utiliza la metodología expo facto y correlacional. Se encontró que la gran minería aporta 94% de la producción anual de cobre peruano, las exportaciones de cobre de la gran minería y la renta minera están positivamente correlacionadas (2000-2019). Ante la contaminación del agua, aire, tierras agrícolas y vulneración de los derechos colectivos de los pobladores en los territorios mineros en Perú, es necesario implementar una regulación minera integral con participación ciudadana e inserción al desarrollo sustentable.

Este artículo explora el impacto de la construcción de presas en el interior de Galicia durante la dictadura franquista a través de los conceptos de cultura y memoria del agua. Las diversas manifestaciones artísticas que surgen como respuesta social ofrecen una alternativa al discurso que se pretendía instaurar desde el régimen. Dichos discursos, a través de la denuncia del expolio, dejan entrever también un paralelismo entre la explotación que sufren las comunidades locales y la naturaleza, fenómeno que resulta de interés en materia de concienciación medioambiental. El estudio de la epigrafía de la zona circundante a las presas sirve como argumento para la conservación de esta memoria y el examen del contexto histórico y cultural de la relación entre los humanos y el medio ambiente natural. A través del análisis de las aras votivas descubiertas en las zonas del interior gallego, se ahondará en la relación que las comunidades locales celtas mantenían con la naturaleza. Se emplea una perspectiva ecocrítica para indagar en el significado cultural e histórico de estas inscripciones y cómo se relacionan con la construcción de presas como Belesar o Castrelo do Miño, y el impacto que tuvo en el medio ambiente y las comunidades locales que vieron como sus pueblos quedaban anegados. El estudio de estas inscripciones asociadas a la cultura y memoria del agua en relación con la construcción de estas presas brinda valiosos conocimientos sobre el contexto histórico, el impacto en el medio ambiente y las comunidades locales, y la relación entre los humanos y el medio ambiente natural. Estos conocimientos no sólo demuestran tener relevancia en el ejercicio de la memoria histórica, sino también como discurso de sostenibilidad para el futuro.

El presente artículo analiza la demanda europea y norteamericana de palo de tinte (Haematoxylun campechianum) durante la Primera Globalización (1870-1914), identifica a sus principales proveedores y compara la magnitud y la tendencia de la oferta mexicana a lo largo de ese mismo periodo. En ese contexto, considerando la importancia de las exportaciones de palo de tinte de Yucatán durante la Colonia, el objetivo central del artículo consiste en analizar y trazar la tendencia de las exportaciones de la Península de Yucatán hacia los principales mercados extranjeros en el contexto del auge exportador del henequén. Asimismo, estima el impacto del comercio del tinte en la depredación forestal de la Península. La investigación utilizó series históricas de distintas fuentes extranjeras, nacionales y locales para el análisis estadístico y de las tendencias de las exportaciones, así como también, el manejo de los registros e informes históricos posibilitaron estimar el impacto de la actividad humana en los bosques tintóreos.

Deste total, 73 itens (critérios) analíticos, 24 (cerca de 33%) receberam nota D, 22 (30%) obtiveram nota E e 6 (8%) tiveram nota F. Com isto, 71% dos itens do EIA avaliado foram considerados inadequados. A partir do presente trabalho, foi possível evidenciar que o EIA avaliado não apresenta qualidade satisfatória, dificultando o processo de licenciamento ambiental e a tomada de decisão sobre a viabilidade socioambiental do empreendimento em questão.

En la producción de lácteos, se genera una gran cantidad de suero de leche, un subproducto que ha sido tradicionalmente considerado como un residuo. Sin embargo, esta perspectiva está cambiando, ya que se está trabajando en la revalorización del suero de leche para reducir su impacto ambiental negativo. Tanto la industria como los hogares están buscando formas de reutilizar el suero de leche, incluyendo su uso en la alimentación humana y animal, así como en la producción de materiales biodegradables como bioplásticos y biocombustibles. Esta revisión tiene como objetivo explorar el impacto ambiental del suero de leche y las oportunidades de su reutilización, destacando su importancia en la transición hacia una economía circular y sostenible.

El consumo de energía y el crecimiento económico han llevado a la degradación del medio ambiente. Las centrales eléctricas son una de las principales fuentes de contaminación. Existe una necesidad de utilizar energías renovables para reducir el impacto ambiental. Sin embargo, en los países en desarrollo, la falta de recursos económicos limita la adopción de energías limpias. Las energías limpias, como la solar, eólica, hidroeléctrica y geotérmica, son fuentes sostenibles de energía. La energía hidroeléctrica puede ser controvertida debido a sus impactos ambientales y sociales. La biomasa y el biogás también son fuentes de energía renovable. La eficiencia energética es otra área importante para reducir la dependencia de los recursos no renovables. El artículo discute la importancia de las energías limpias y el desarrollo sostenible en el Perú. Se menciona el potencial de la energía de las olas marinas, el bioetanol y el biodiesel como fuentes de energía renovable. También se abordan los impactos ambientales de los "negocios sucios" y las implicaciones socioeconómicas de las energías limpias. Se discuten los conflictos de interés y la regulación normativa en el país, así como las perspectivas futuras y la necesidad de un desarrollo energético estable y sostenible. Palabras clave: Energías limpias, negocios sucios, impacto ambiental, sostenibilidad.

El objetivo de este estudio fue analizar las problemáticas más significativas en relación con el paisaje que fueron identificadas por parte de la población de la isla de Mexcaltitán, Nayarit, México, durante el período 2019-2022. La información se obtuvo a través de entrevistas semiestructuradas y utilizando el método de análisis temático fenomenológico. Los resultados obtenidos destacan tres problemáticas principales: la contaminación generada por residuos sólidos, los impactos locales derivados de la infraestructura de la isla y los conflictos de interés que surgen en relación con las autoridades y su vinculación con el turismo.

El aumento en la generación de residuos y el constante crecimiento, requieren cuantificar las emisiones para dimensionar la problemática y contribuir en la mitigación. El estudio evaluó el impacto por residuos no peligrosos mediante indicadores orgánicos e inorgánicos, tales como las toneladas anuales de papel y cartón, plásticos, metal ferroso, residuos de comida, jardín y madera, para tres Escenarios Base (EB) para el periodo 2016-2018, escenario de referencia (integración de los escenarios base) y escenario futurible determinado por el incremento en la producción. Estos escenarios se construyeron con base en la disponibilidad de información del área de seguridad y medioambiente de la industria, para calcular el CO2-eq (Dióxido de Carbono Equivalente) mediante la herramienta GEI-MRS basada en parámetros preestablecidos que se adaptan a la disposición de información y a las condiciones del caso de estudio. El EB para el 2016 estimó 60 t/a/CO2-eq, el EB del 2017 presentó 46 t/a/CO2-eq, el EB del 2018 generó 14 t/a/CO2-eq, mientras que el escenario referencia determinó 60 t/a/CO2-eq. Los datos aportan una visión prospectiva para la toma de decisiones en una industria petroquímica del Sur de Tamaulipas, contribuyendo a la problemática del incremento de los residuos desde un sector particular con implicaciones regionales.

The present investigation is oriented towards the determination of the economic, environmental and energetic feasibility of the anaerobic biodigestion technology suitable for a dairy agroecosystem, established in "El Guayabal" University Farm, belonging to the Agrarian University of Havana. For this, animal species existing in the scenario is determined, since it will contribute the organic waste to the biodigester. The number of animals is also determined, considering the movement of the herd, which would make it possible to determine the biomass generated daily with the purpose of establishing the sizing of the appropriate biodigester technology and knowing the behavior of the economic and energy parameters. Among the main results obtained, it was evidenced that the installation of a tubular polyethylene biodigester is more feasible than the installation of a fixed dome biodigester, meaning an economic saving of 19,796 pesos for the concept of technology selection. The necessary volume of this technology must be 20 m³, making it possible to produce 190 kg/day of biofertilizers, which represent an economic contribution of 2,375 pesos (95 USD) constituting an added value, in addition to the energy and economic benefits to be obtained. Moreover, with the introduction of the selected anaerobic biodigestion technology, it is possible to generate electrical energy to drive a fodder mill, a refrigeration system, a mechanical milking system, lighting, electric fencing and a water pumping system, all which require the acquisition of a 35 kW biogas generator.
