Landscape units are conceived as a part of the territory that share similar physical and geographic characteristics. Their delineation can contribute to identify the physical and social dynamics that emerge in the spatial environment and to propose strategies of planning and management of the territory. The main objective was to make a historical delineation of landscape units in the Duero river basin that demonstrate the dynamics of changes in the territory, the description of the actors involved, and the affectations in the natural and social environment. We analyzed the vegetation change and urban growth from 1983 to 2014, incorporating climatic, edaphic, and topographic variables. A Principal Component Analysis was performed with the information and results were used in Maximum Likelihood procedure to define different clusters based on environmental characteristics. We defined five categories from the Landsat images. Results showed landscape units with homogeneous environmental characteristics and some differences in the units' delineation were mainly influenced by political and socioeconomic factors. Temporally there was an increased tendency of landscape units, three in 1983, nine in 1990, 1995, 2000 and 2011, and eight in 2014. This increase resulted from territory fragmentation because of berries and avocado cultivars expansion over wooded area.
El cambio climático es un fenómeno que propicia cambios ambientales intensos que modifican las condiciones naturales en los territorios, lo que afecta en la región Alta Guajira en el municipio de Uribia a los indígenas Wayyu, donde prolongadas sequías ponen en riesgo la etnia, sumado a la inobservancia institucional y la ausencia de medidas adaptativas acorde a las formas de vida del pueblo Wayyu. Se buscó interpretar los efectos del cambio climático en el territorio Wayyu, mediante un proceso participativo de educación ambiental en la comunidad Guerrero en el norte de Colombia, articulando el saber ancestral de los usos y costumbres entorno al agua con medidas de adaptación al cambio climático para el aprovechamiento y uso sostenible del recurso hídrico. La investigación se desarrolló de mayo de 2019 a mayo de 2020, siguió el método etnográfico, se aplicaron entrevistas semiestructuradas y se desarrollaron espacios de intercambio de saberes a través de asambleas con la comunidad. Se diagnosticó la problemática entorno al agua y la identificación de escenarios de riesgo al cambio climático, se propusieron medidas de adaptación al cambio climático acordes al contexto cultural, con la participación de los Wayyu en sus formas y tiempos.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
