El presente trabajo tuvo como objetivo realizar una revisión sistemática del uso de imágenes Sentinel-2 para el monitoreo de la cobertura boscosa a nivel global, para lo cual se empleó el protocolo propuesto por Prisma 2009. La búsqueda de los artículos científicos publicados entre el 2015 y 2021 se realizó en las bases de datos: Scopus y Science Direct, analizándose un total de 65 artículos en los que se detalla los diferentes tipos de clasificadores utilizados para procesar las imágenes S-2, la exactitud temática lograda en la cartografía, así como el aumento, mantenimiento o retroceso de los bosques y sus principales causas a nivel mundial. Como resultados se encontró que Random Forest (RF) es el clasificador más utilizado para el procesamiento digital de las imágenes S-2, el cual logra en la mayoría de los casos una exactitud temática superior al 85%. En los trabajos multitemporales, se ha encontrado que la cobertura boscosa en Sudamérica y África se ha visto disminuida por actividades como la agricultura y ganadería. Mientras que, en algunos países asiáticos la cobertura boscosa se ha incrementado como consecuencia de la implementación de programas de reforestación y manejo forestal comunitario. Por lo que lo resultados sugieren que las imágenes Sentinel-2 presentan un enorme potencial para llevar a cabo el seguimiento continuo y sistemático de la pérdida o ganancia de los bosques en todo el planeta.

This study rigorously examines the evolution and future prospects of scientific journals in Peru, with a particular focus on those affiliated with state-sanctioned public universities. The research includes a comprehensive evaluation of the official online resources of each university, following the list sanctioned by the Superintendencia Nacional de Educación Superior Universitaria (SUNEDU). This research includes journals included in the Sistema Regional de Información en Líneo para Revistas Científicas de América Latina, el Caribe, España y Portugal (Latindex Catálogo 2.0), as well as those indexed in prominent databases such as SciELO, Web of Science (WOS), and Scopus. Using careful data analysis methods, including tabulation in Excel and Minitab 19, the study identified 205 scientific journals. Of these, 51 are indexed in at least one of the aforementioned databases, while 154 remain unindexed, highlighting a significant challenge for editorial teams. In particular, only four journals are indexed in Scopus, mainly from the Universidad Nacional Mayor de San Marcos and the Universidad Nacional de Trujillo. The research concludes that the development of these journals is significantly correlated with their Google Scholar h-index. The results argue for greater support for public universities to promote the indexing of their scholarly journals, thereby increasing the visibility and impact of their research on regional, national, and international platforms. Future strategies should include incentive policies to encourage scholarly contributions to locally based journals.

Objective: The objective of this study is to analyze the scientific contribution of the regular teachers of the Universidad Nacional Intercultural Fabiola Salazar Leguía de Bagua (UNIFSLB) since their first linkage. Method: A review of databases (Latindex 2.0, Scielo, Web of Science and Scopus), as well as relevant management documents was carried out. Likewise, the annual growth rate and the behavior of the promotion and dissemination of science through its journals hosted in OJS were evaluated. Data analysis was carried out using Minitab 19.1 and VOSviewer programs. Results: They reveal a remarkable annual growth rate of 31.12%, with a scientific production of 115 articles. In 2022, publications in Scopus and Scielo stand out with 32 articles and 2 in Scielo, respectively. The dissemination of scientific production is mainly through the scientific and academic journals "Dékamu Agropec" with 53 publications and "Manguare" with 32. However, the presence of publications related to interculturality is limited (5 in Web of Science and 2 in Scopus). Conclusions: The minimal number of publications could be due to insufficient economic allocation for research. Therefore, it is necessary to implement policies that promote the valuation of ancestral knowledge and that this is validated through the generation of knowledge in accordance with the lines of research. This, in turn, is associated with the low visibility of keywords related to specific topics.

The objective of this research was to evaluate the eco-efficiency of the district municipality Jose Crespo y Castillo de Peru; for this, a baseline was drawn up and indicators were formulated and implemented for the eco-efficiency plan. The standardization of the data was carried out by applying maximums and minimums. The weighting of indicators was established using the Delphi method and the instruments were validated by experts. The development of the biogram was carried out based on the eco-efficiency indices. Higher than expected results were obtained in the planning stage. The state in which the district municipality Jose Crespo y Castillo is located was also known through the biogram, which was not eco-efficient and unstable.
