Decision support systems (DSS) for wastewater treatment plants - A review of the state of the art.
2019
The use of decision support systems (DSS) allows integrating all the issues related with sustainable development in view of providing a useful support to solve multi-scenario problems. In this work an extensive review on the DSSs applied to wastewater treatment plants (WWTPs) is presented. The main aim of the work is to provide an updated compendium on DSSs in view of supporting researchers and engineers on the selection of the most suitable method to address their management/operation/design problems. Results showed that DSSs were mostly used as a comprehensive tool that is capable of integrating several data and a multi-criteria perspective in order to provide more reliable results. Only …
Towards more sustainable food systems. Addressing food waste at school canteens
2018
Food Waste is a global significant issue for ethical, environmental and economic reasons, while its management is difficult due to its frequent low visibility. Individual choices and preferences are closely related to the generation of food waste although likely to be modified through education and awareness campaigns. In particular, school canteens are big generators of food waste and, at the same time, provide a great opportunity to improve habits regarding nutrition and education on sustainability, thus impacting the future of the food system. The end purpose of this research is identifying the causes of food waste and unveiling best practices towards its reduction. To achieve this goal,…
Corporate social responsibility reporting and institutional theory
2016
Objeto: La investigación sobre divulgación de información de sostenibilidad se ha centrado en el ámbito de la empresa, siendo escasos los trabajos que analizan las diferencias entre países. El objetivo es identificar los factores que explican las diferencias en el suministro de información de sostenibilidad a nivel macroeconómico. Diseño/metodología/enfoque: La muestra incluye 9,570 memorias elaboradas en el marco de la Global Reporting Initiative en 53 países en el periodo 2007-2012. La información para cada país se ha estandarizado por millón de habitantes en cada año. Se han utilizado modelos de regresión múltiple para estudiar la incidencia de la gobernabilidad, la cultura y la globaliz…
Water Supply in Rwanda Use of Photovoltaic Systems for Irrigation
2015
The current energy situation in the world where most of the energy needed is generated from non-renewable sources such as fossil fuels is no longer sustainable. During few years, nonrenewable sources have become an interesting solution to provide energy to areas with small needs of electricity, rather than using non-renewable sources. Therefore, this project has pursued to implement photovoltaics panels to supply energy in a rural region in central Africa, contributing to the development of the area and proving that this technology is viable to pump water for irrigation instead of the conventional electric grid. A rural area between Kidogo Lake and Rilima town, in Bugesera district of Rwand…
La Educación para el Desarrollo Sostenible aplicada a la enseñanza-aprendizaje del alemán como lengua extranjera
2022
Desde la irrupción de la Agenda 2030 para el Desarrollo Sostenible, que constituye para todas las personas una oportunidad y una exigencia para responder a los desafíos del mundo, las universidades europeas dentro del espacio generado por la European Higher Education Area (EHEA) asumen su responsabilidad. El carácter integral de la Agenda 2030 permite a la Universidad la construcción de un mundo comprometido con el desarrollo sostenible e inclusivo, la justicia, la dignidad y la igualdad de las personas, dando respuesta a los desafíos que el contexto global presenta para las universidades y para la sociedad internacional en su conjunto. La Educación para el Desarrollo Sostenible (EDS), por …
El arte urbano como método de aprendizaje : propuesta didáctica en el ámbito de la educación no formal
2021
El Arte Urbano surge en el contexto público como manifestación cultural de problemáticas sociales. En esta propuesta educativas se establece la relación del uso del Arte Urbano como medida de aprendizaje a partir de un recorrido cultural por diferentes murales, artistas y países con el objetivo de trabajar además desde el punto de vista de los Objetivos de Desarrollo Sostenible, la importancia de conocer nuestra realidad social, política, cultural y ambiental. Se busca que el destinatario reflexione sobre el significado y el valor del Arte actual, ampliando es espacio usual de los grandes museos, la belleza y la perfección para adentrarse en las calles de las ciudades cargadas de singularid…
Fuzzy set qualitative comparative analysis (fsQCA) applied to the adaptation of the automobile industry to meet the emission standards of climate cha…
2021
Abstract Facing global climate change challenges entails a sustainable development of transportation. Governments and automobile manufacturers are highly aware of how a large-scale deployment of Electric Vehicles (EVs) can reduce greenhouse gas (GHG) emissions and mitigate global warming. This study aids the design of the adaptation strategies of the automotive industry to meet global goals on climate change by means of a fuzzy-set qualitative comparative analysis (fsQCA), which makes it possible to measure the level of actors’ satisfaction. This allows identification of a combination of factors leading to the outcome while dealing with uncertain environments due to the heterogeneous nature…
VentQsys: Low-cost open IoT system for CO2 monitoring in classrooms
2021
AbstractIn educational context, a source of nuisance for students is carbon dioxide ($$CO_2$$ C O 2 ) concentration due to closed rooms and lack of ventilation or circulatory air. Also, in the pandemic context, ventilation in indoor environments has been proven as a good tool to control the COVID-19 infections. In this work, it is presented a low cost IoT-based open-hardware and open-software monitoring system to control ventilation, by measuring carbon dioxide ($$CO_2$$ C O 2 ), temperature and relative humidity. This system provides also support for automatic updating, auto-self calibration and adds some Cloud and Edge offloading of computational features for mapping functionalities. From…
Cambio Climático. Objetivo Durbán
2011
Revista Eureka sobre Enseñanza y Divulgación de las Ciencias está contribuyendo, con la publicación de numerosos trabajos y, en particular, con su sección "Educación científica y sostenibilidad", a los objetivos de la Década de la educación por un futuro sostenible, instituida por Naciones Unidas para que los educadores de todos los niveles y áreas contribuyamos a proporcionar una percepción correcta de los problemas a los que se enfrente la humanidad y a fomentar actitudes y comportamientos favorables para el logro de un futuro sustentable. Acogiéndonos a este compromiso de Revista Eureka queremos hacernos eco de los resultados de la Cumbre del Clima celebrada en Cancún en diciembre de 201…
