El objetivo de esta investigación fue identificar las representaciones sociales sobre la gestión ambiental para la sustentabilidad compartidas por la comunidad escolar de la Universidad Español campus Diamante en Acapulco, Guerrero. El alcance metodológico fue descriptivo y el diseño mixto. Se aplicaron 276 cuestionarios y 11 entrevistas al personal directivo, docente y no académico y a estudiantes. Los datos cualitativos se procesaron mediante análisis de contenido y los cuantitativos a través de redes semánticas naturales y estadística descriptiva. En cuanto al cuestionario, las respuestas predominantes indicaron que la información adquirida por la comunidad escolar proviene, principalmente, de asignaturas como la de biología (26.7 %); en relación con las representaciones sociales, 41 % de los entrevistados piensa que el concepto gestión ambiental se enfoca al cuidado, 31 % desconoce la sustentabilidad y 30 % relaciona la sustentabilidad con la conservación de los recursos naturales. Asimismo, para 47 % de los encuestados, la finalidad de la gestión ambiental es, básicamente, ahorrar y administrar los recursos. Se concluye con la necesidad de desarrollar procesos de formación con toda la comunidad escolar para transitar de una conceptualización conservacionista y utilitarista a la construcción de representaciones sociales más sólidas, complejas y dinámicas, orientadas a la sustentabilidad.
Flooding due to climate change is recurrent and has intensified in the lower course of the Coyuca River. This paper implements a multivariate analysis, including conditioning and triggering factors to develop flood susceptibility mapping in an information-deprived region to help prevent/mitigate flooding. Flood-susceptible areas were identified using the multi-criteria decision analysis (MCDA) methodology, specifically, with the hierarchy analysis process (AHP). Four conditioning and one triggering influence factors were analyzed. The influence weights of each variable were determined using Saaty’s methodology (AHP). Thematic maps for each variable were created and multiplied by their influence value using the raster calculator and added to their variable group to obtain the flood susceptibility map. The findings showed that the susceptibility to flooding was very high in 41.82%, high in 35.95%, medium in 21.25% and low in 0.98% of the study areas. It was revealed that 44.44% of the localities occupy areas of very high susceptibility to flooding. Susceptibility increases in the localities closest to the river.
Air pollution is a global environmental problem that affects the population. This work demonstrates the perception of air quality by the population of the urban area of the municipality of Acapulco, Guerrero, Mexico. To meet the objective, a survey of 36 questions was applied to a sample of 382 people living in the main crossing points of vehicles, where there is more traffic and more severe pollutant concentration problems. We decided to apply the grouping method within a radius of 500 m around the selected intersections, where 95% of the respondents are aware that the air they breathe has a certain degree of contamination.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
