Vegetation growth development on agricultural areas. Trend slopes of annual vegetation growth (\(NDVI_{MEAN}*\)) are analyzed versus irrigation intensity (a) and aridity (b). General Notes: Only significant vegetation growth trends (p < 0.05) are considered. Agricultural areas which were cultivated after the start of the analyzed period are excluded (Methods). Irrigation intensity of an agricultural pixel is thereby characterized at the beginning between 2001 and 2003 (Fig. 9). The analysis related to aridity focuses on rather highly irrigated areas (irrigation intensity > 50). Black dots: medians of all data points. red dots: medians of negative trends. red crosses: proportion of negative trends.
