El análisis se llevó a cabo en el Bosque Reservado de la Universidad Nacional Agraria de la Selva y en el laboratorio de Conservación de Suelos de la Facultad de Recursos Naturales Renovables con el objetivo de evaluar el carbono acumulado en la hojarasca, raíces y en el suelo, en la colina baja, colina alta y montaña baja del BRUNAS. Se realizaron 15 parcelas de muestreo con un área de 500m2 (50 m x 10 m), dentro de estas parcelas se obtuvo el muestreo de hojarasca en sub parcelas de 5m x 5 m, para las el muestreo de raíces y suelo se hizo en monolitos de 0,30 m x 0,30 m x 0,30 m. Se utilizó el Análisis estadístico para la comparación de media mediante las pruebas de normalidad y contrastes a un nivel de significancia de 5%. En la colina baja la hojarasca almacenó 11,40 tC/ha., en colina alta 8,47 tC/ha y montaña baja 8,93 tC/ha., el carbono almacenado en raíces en la coli...

The lagoons in the Amazon are being impacted by agricultural activities and the information about their sediments is scarce; therefore, the objective of the study was to determine the physicochemical characteristics of the sediments of the Laguna Bella, wetland which will contribute to the knowledge of its environmental quality. Thus, using standardized techniques, sediments collected at six sampling points were analyzed. The results show the values of density, organic matter, conductivity, pH, organic matter, N, P, Pb, Cu, Fe, Mn, Zn and K, which were compared with five international standards. Considering the Ontario standard, organic matter is below the severe effect level; N is between the lowest and most severe effect level, while P is below the lowest effect level concentration; Pb is at a moderately contaminated level, according to the USEPA standard, but exceeds the NOAA standard...

Careful landfill selection with minimal environmental impact is vital for urban planners. This study aims to identify suitable sites for controlled landfills using Fuzzy-AHP integrated with Remote Sensing and GIS, considering a 20-year projection of population and solid waste generation. Initially, twelve sub-criteria were identified, grouped into environmental, socio-economic, and physical categories, and then weighted using paired comparison matrices involving nine experts. The sub-criteria were rasterized and classified into four suitability levels. The weighted overlay of sub-criteria maps generated a territorial suitability model. Within the Alto Utcubamba Commonwealth (Amazonas, Peru), 0.069%, 41.70%, 66.934%, 0.20%, and 12.4% of the territory are suitable, moderately suitable, less suitable, unsuitable, and restricted, respectively, for landfill establishment. Subsequently, 16 hig...
