Metal mining is one of the economic pillars of the Peruvian economy. Peru is the main producer of gold, zinc, lead, and tin in Latin America and the second largest producer of copper, silver, and zinc worldwide. Despite its economic importance, mining has also left a plethora of Mining Environmental Liabilities (MEL) whose inadequate waste management represents a risk for both the environment and human health and is a common trigger of social problems. The Cajamarca región is the second región in Peru in terms of the number of MEL sites with the majority of them located in the Hualgayoc district. The goal of the PhD project is the assessment of the environmental impact of MEL in the Peruvian Andes using as an example two post-mining sites in the Hualgayoc district. This evaluation includes the study of soils and native plant species in terms of their metal accumulation potential and th...

La ciudad de Lima presenta cada día mayor contaminación, siendo esta la causa del incremento de las enfermedades respiratorias. La OMS advierte sobre el daño en el desarrollo neurológico, psíquico y motor que genera la contaminación del aire, asimismo el 93% de la población mundial de niños está expuesta a niveles de partículas finas PM2.5 por encima de lo permitido. El 40% de la población mundial está expuesta a elevados niveles de contaminación de aire en su hogar debido a la quema de leña, carbón y otros desechos sólidos. La contaminación del aire y del entorno de los pobladores de Lima Cercado está generando el aumento de enfermedades cerebrovasculares, canceres de pulmón, neuropatías crónicas y agudas, como el asma. La contaminación del aire no solo de da por la contaminación de partículas sino también por la presencia de Dióxido y Monóxido de Carbono, Nit...

Lake Titicaca, at present, is considered a natural wonder of the world. It is the habitat of many unique and endangered native species, with flora and fauna of great diversity, site of nesting of many migratory birds, source of fresh filtered water, by its volume, regulates the air temperature of the region allowing climate conditions less aggressive for life. However, in the last decades, the anthropogenic influence affected its conservation. The problems that Lake Titicaca presents are concentrated in the littoral zone, the bays and the Lake Minor. Large quantities of wastewater that enter directly or poorly treated, in particular to the Bays of Puno and Copacabana, are generating eutrophication processes. The effect of the discharges are the increase of sediments accumulated in the bottom, explosive flowering of Lemna sp. algae on the surface, reduction in dissolved oxygen levels, and...

En las últimas décadas, la psicología ambiental ha intentado abordar la contaminación por plástico a partir del estudio de los factores psicosociales individuales que influyen en el comportamiento proambiental. Sin embargo, la literatura reciente enfatiza la necesidad de analizar los problemas socio-ambientales desde una perspectiva colectiva y sociopolítica. En esa línea, la presente investigación mixta tuvo como objetivo general identificar el efecto de la identidad de lugar, las normas sociales, las metas colectivas, la eficacia colectiva, el clima emocional y el comportamiento proambiental en la acción colectiva proambiental de residentes de la ciudad de Lima. Se empleó un diseño convergente que integró dos estudios desarrollados de manera paralela: un estudio cuantitativo con un diseño asociativo correlacional y un estudio cualitativo con un diseño de análisis temáti...
