The Cuturivi community presents a production system in this area, which includes activities, such as agriculture, livestock grazing, deforestation, grasslands burning and the land appropriation by the charge producers agricultural operations. Together, these anthropogenic activities affect the conditions from moorland ecosystem. In this context, the research has as aim to make a vegetation cover multi-temporal analysis in the moorland from Cuturivi community, located in the Pujilí parish, Cotopaxi province. For this, it was used the Corine Land Cover methodology, which is based on Landsat-type satellite images to build vegetation cover cartographic maps, using ArcGIS and QGIS software. The research approach is qualitative and comparative descriptive. During the process, it was applied preprocessing to each satellite image, to subsequently, to generate the supervised classification. This classification was validated, through a confusion matrix compared with the taken coordinates, by assessing its significance by the Kappa index. Further, it was elaborated a transition matrix to calculate the losses and gains each vegetation cover type. Additionally, it was carried out a community perception survey, through the Google Form application, focused on the water resource conservation topic in the moorlands. The multitemporal analysis results indicated changes and alterations in the shrub and herbaceous areas. In the 2018, the shrub and herbaceous cover encompassed 2601.03 hectares (26%), while in 2020, it increased to 2864.71 hectares (29%) and in the 2022, it decreased to 2219.43 hectares (23%). This analysis also revealed a decrease in shrub and grassland areas, which were replaced by an increase in agricultural land. Data analysis related to moorlands, it reveals important patterns and concerns in their management. It stands out the young people active participation and women in conservation activities and sustainable water resources use, although there is a gap between perception and real participation. |
