Abstract
El presente estudio se realizó en la provincia de Imbabura, cantón Cotacachi, parroquias de Quiroga y Sagrario en las comunidades de Perafán, Tunibamba, Alambuela, Cercado, San Pedro, Azaya, Santa Bárbara, Topo Grande, Batan, Iltaquí, Morochos y San José, que tiene como principal fuente de ingreso las actividades agrícolas y pecuarias. Con la obtención de los resultados se observó que los cambios suscitados en la cobertura vegetal son debidos a actividades antrópicas como, por ejemplo: avance de la frontera agrícola, quemas, entre otros. Para considerar los cambios de la vegetación, se realizó un análisis multitemporal de los años 1991, 2008 y 2015 de la cobertura vegetal con el apoyo de imágenes satelitales; el mismo que se basó en un modelamiento hidrológico para analizar la implicación que tiene el recurso hídrico con la cobertura vegetal existente del lugar, permitiendo conocer más a detalle los recursos agua y vegetación, facilitando la implementación de propuestas encaminadas a la conservación, protección y manejo adecuado de los recursos bióticos y abióticos del área estudiada y así ser aprovechados en posibles proyectos de sustentabilidad, ecoturísticos, investigativos y otros. Por otro lado, la capacitación a los comuneros sobre el uso adecuado de los recursos que disponen y las actividades que pueden desarrollar para mantenerlos en su estado natural son el eje principal para lograr cada una de las propuestas presentadas y esto se lo puede lograr a través de la integración de los actores de la comunidad con el objetivo de alcanzar el buen manejo de los recursos, ya que de ellos depende su subsistencia.
The present study was conducted in the province of Imbabura, Cotacachi canton, Quiroga and Sagrario parishes in the communities of Perafán, Tunibamba, Alambuela, Cercado, San Pedro, Azaya, Santa Bárbara, Topo Grande, Batan, Iltaquí, Morochos and San José, where agricultural and livestock activities are the main source of income. With the obtaining of the results it was observed that the changes provoked in the vegetal cover are due to anthropic activities such as, for example: advance of the agricultural frontier, burns, among others. To consider changes in vegetation, a multi-temporal analysis of the years 1991, 2008 and 2015 of the vegetation cover was carried out with the support of satellite images\; the same one that was based on a hydrological modeling to analyze the implication that the hydric resource has with the existent vegetal cover of the place, allowing to know more in detail the resources water and vegetation, facilitating the implementation of proposals directed to the conservation, protection and management adequate biotic and abiotic resources of the studied area and thus be used in possible projects of sustainability, ecotourism, research and others. On the other hand, training community members on the appropriate use of the resources they have and the activities they can develop to keep them in their natural state are the main axis to achieve each of the proposals presented and this can be achieved through of the integration of the actors of the community with the objective of achieving the good management of the resources, since their subsistence depends on them.
