El estudio tiene por objetivo evaluar los factores de degradación de la totora, variación de las características y conocer el manejo familiar-comunal, que determinan el deterioro de las macrofitas del ecosistema del Lago Titicaca peruano, divididas en 22 zonas de estudio con presencia de totora y llachu. El método usado consiste en la recolección de datos "in situ" densidad, variación de tallos verdes y amarillos, biometría, biomasa, perfil de evaluación de las macrofitas y descripción de las áreas de totorales. Para la cobertura de totorales se utilizó imagen satelital (2008). Adicionalmente se complementa con la evaluación del impacto ambiental utilizada la Matriz Causa - Efecto de Leopold. Como resultados se determinan la presencia de contaminación orgánica e ingreso de aguas ácidas, oleajes aproximadamente de 0.5 a 1.0 m. de altura, inundación rápida y lenta por efec...

El trabajo de investigación comprende la evaluación de las técnicas de trasplante en el ecosistema del lago Titicaca y los factores ambientales que influyen directamente en el desarrollo de la totora Schoenoplectus tatora Kunt Palla, ubicadas en las comunidades de San Pedro, Choquetanca, Laconi y Tacasaya de los distritos de Zepita, llave, Platería y Chucuito respectivamente. Como metodología de trasplante se utilizó técnicas Takxataña, Ch'ampa, Cala y Ñuqiña. Para evaluar el repoblamiento se han determinado los factores ambientales (físicos y químicos) y las técnicas apropiadas que permite la recuperación de los ambientes degradados, así como la conservación de la diversidad biológica. Los datos fueron analizados mediante el análisis de varianza utilizando el diseño completamente al azar y la prueba de rango múltiple Tukey. Además se ha aplicado el análisis de regr...

The objective of this research was to determine noise levels at critical points in the city of Bagua. The methodology was descriptive, gathering information in the critical points of the city (Av. Circunvalación, external market, internal market, Av. Héroes de Cenepa and Plaza Héroes de Cenepa), with the use of a digital sound level meter (Sound Meter), the data were taken in three shifts, during 6 months of 2019.  The results indicate that for Circunvalación Avenue the maximum values fluctuate between 74 - 82 dB obtained in the month of January, February (daytime hours) and the minimum was 39 -53 dB recorded in the month of May and June (nighttime hours). All parameters were compared with the Environmental Quality Standards for noise (ECAs) in Residential Areas. The current results exceed 50% of the ECAs causing environmental pollution. In the external market, the maximum value...

The objective of the study was to investigate the effect of the application of different organic fertilizers on the development of plant height, bulb diameter and germinated cloves of garlic (Allium sativum). A completely randomized design (DCA) was used with a total of 4 treatments with 3 repetitions. The treatments were T0: Absolute control without substrate, T1: Agricultural land proportion 1:1 with vermicompost with sheep manure, T2: Agricultural land plus Biol at 10% in aqueous dilution, T3: Agricultural land plus 10% ash from organic waste and without addition it acted as a control. Data were analyzed with the SAS GLM procedure and treatment means were compared with Tukey's test. The results showed that the addition of Biol at 10% in aqueous dilution and Vermicompost with sheep manure to the garlic crop (Allium sativum) had the most beneficial effect on germination, diameter and he...

The general objective of the study was to determine the effect of the didactic strategies of the teacher based on the paradigm of the seven knowledge of Edgar Morín, in the learning of environmental education, in students of the Higher Institute of Public Technological Education Santos Villalobos Huamán Region Cajamarca Peru. The focus of quantitative research, quasi-experimental design; the sample consisted of 20 students (10 from the control group and 10 from the experimental group); the instrument used was an environmental education exam, structured by 40 items, on the vigesimal scale; what allowed to evaluate the learning. The results of the investigation show that after using the paradigm of Edgar Morín in the experimental group of students, there were significant differences compared to the control group; also descriptively the means of the notes of the experimental group, were ...
