Abstract In this paper we examine the possible differentiations of the E. de Martonne climatic aridity index in conjunction to Normalized Difference Vegetation Index – NDVI index. For this purpose meteorological data cover the period from 1958 to 2011 was used. Also for three Landsat satellite images NDVI index was performed. The results for the climatic index show a trend towards characterizing the climate as warmer and drier. The latter conclusion is consistent with intense land use change in the area of interest, and is due to a shift in the management of surface waters used for crops irrigation in the region.
