Description
Abstract
ABSTRACT The risk of desertification in the Mediterranean Basin, is evident in the southeast of the Iberian Peninsula, where land degradation reaches unsustainable levels. This study aims to analyse the temporal evolution of land covers as an indicator of soil desertification. Time series of vegetation indices derived from satellite remote sensing images were analysed. Various climatic variables as possible causes of land covers behaviour were considered. The existence of a large inter-annual and intra-annual variability for all land covers and precipitation was observed. It is showed an association between temporal patterns of vegetation series of different land uses and rainfall.
