Integración de imágenes de sensores remotos en el desarrollo de indicadores medioambientales en cuencas mediterráneas. Aplicación al seguimiento de su estado hídrico y productividad

This thesis proposes the use of remote sensing images of different spatial, spectral and temporal resolutions that, combined with meteorological, hydrological and phenological data, can be used to produce indicators of different ecosystem variables related to productivity and water status in different unique systems of the Mediterranean region. Specifically, the development of three indicators closely linked to each other is proposed: an indicator of the water status of the soil at the end of the dry season from the state of different vegetation covers; an indicator of the productivity of natural pastures, the main food support for extensive livestock in dehesa ecosystems, based on their status and the climatic conditions of the period evaluated; and, finally, an indicator of the relationship between water state of the soil and the natural pasture phenological state.
