Abstract
Este estudio se realizó en la provincia de Imbabura, en el Cantón Otavalo en las parroquias de Miguel Egas Cabezas y San Juan de Iluman, en el Cantón Antonio Ante en la parroquia de San Roque donde se determinó que existe un cambio de cobertura vegetal por medio del mapeo que se lo realizó con imágenes Landsat de los años 1993, 2005 y 2018, además por medio de la encuesta que se realizó a las tres parroquias, se estableció que la principal fuente de ingreso son las actividades pecuarias y agrícolas. Para considerar el cambio de la vegetación se optó por realizar un análisis multitemporal de los años 1993, 2005, 2018 de la cobertura vegetal en las faldas del cerro Imbabura, enfocadas en las tres parroquias con el apoyo de imágenes satelitales; y la identificación de actores claves para determinar las posibles causas del cambio de la cobertura vegetal, con esto realizar una propuesta de conservación. Sin duda ha existido un cambio de la cobertura vegetal en cada una de las tres parroquias donde se realiza el estudio, mientras que el bosque ha ido desapareciendo, ha existido un crecimiento poblacional para el año 2018. Es por ello que se necesita, elaborar una propuesta de conservación, la cual priorizará los diferentes factores bióticos que posee las faldas del cerro Imbabura y así promover buenas prácticas ambientales y emplear un adecuado desarrollo sustentable enfocado hacia las diferentes comunidades que habitan en el lugar de estudio. De esta manera se pretende proteger al cerro Imbabura para las futuras generaciones.
This study was carried out in the province of Imbabura, in the Otavalo Canton in the parishes of Miguel Egas Cabezas and San Juan de Iluman, in the Antonio Ante Canton in the Parish of San Roque where it was determined that there is a change in vegetation coverage through of the mapping that was carried out with Landsat images of the years 1993, 2005 and 2018, also by means of the survey that was carried out to the three parishes, it was established that the main source of income is livestock and agricultural activities. To consider the change in vegetation, a multitemporal analysis of the years 1993, 2005, 2018 of the vegetation cover on the slopes of the Imbabura hill, focused on the three parishes with the support of satellite images, was chosen; and the identification of key actors to determine the possible causes of the change in the vegetation cover, with this a proposal for conservation. Undoubtedly there has been a change in the vegetation coverage in each of the three parishes where the study is conducted, while the forest has been disappearing, there has been a population growth for the year 2018. That is why it is necessary to develop a conservation proposal, which will prioritize the different biotic factors that the slopes of the Imbabura hill possess and thus promote good, environmental practices and use an adequate sustainable development focused on the different communities that inhabit the place study. In this way it is intended to protect the hill Imbabura for future generations.
