Color Plates Plate 1 Study area location. (See also Fig. 2.1 on p. 18) 335
336 Color Plates Plate 2 Soil saline levels. (See also Fig. 2.4 on p. 27)
Color Plates 337 Plate 3 SSI (Soil Salinity Index) image calculated from the Landsat ETM+ image acquired on October 7, 2002, and photos showing the surface state of salt-affected soils in different parts of the study area. The class numbers correspond to the different degrees of salinity in ascending order. (See also Fig. 4.8 on p. 63)
338 Color Plates Plate 4 Classification image of Landsat MSS acquired on June 23, 1977. The classes from NDVI_class1 to NDVI_class7 were obtained by binning the NDVI values; higher class numbers indicate higher NDVI values and thus greater density and greenness of vegetation. (See also Fig. 4.9 on p. 66) Plate 5 Classification image of Landsat TM acquired on October 17, 1991. The classes from NDVI_class1 to NDVI_class7 were obtained by binning the NDVI values; higher class numbers indicate higher NDVI values and thus greater density and greenness of vegetation. (See also Fig. 4.10 on p. 66)
Color Plates 339 Plate 6 Classification image of Landsat ETM+ acquired on October 7, 2002. The classes from NDVI_class1 to NDVI_class7 were obtained by binning the NDVI values; higher class numbers indicate higher NDVI values and thus greater density and greenness of vegetation. (See also Fig. 4.11 on p. 67) Plate 7 SSI (Soil Salinity Index) calculated from Landsat ETM+ image acquired on October 7, 2002. Class numbers correspond to different degrees of salinity in ascending order. (See also Fig. 4.12 on p. 67)
340 Color Plates Plate 8 SSI (Soil Salinity Index) calculated from the image acquired on October 17, 1991. Class numbers correspond to the different degrees of salinity in ascending order. (See also Fig. 4.13 on p. 68) Plate 9 Dry areas of the world today (See also Fig. 7.5 on p. 111)
Color Plates 341 Plate 10 Precipitation anomalies (top: mm/day, bottom: %) calculated for the IPCC B2 scenario with the French CNRM model, comparing the averages for 1950 1999 and 2050 2099. Left: for December March. Right: for June September. (Source: Académie des Sciences 2006) (See also Fig. 7.6 on p. 112)
342 Color Plates Plate 11 Organization of the khettaras in central Haouz, west Marrakech. (Most of the seguias still run, while most khettaras are out of order) (Source: ORMVA Archives) (See also Fig. 10.6 on p. 156)
Color Plates 343 Plate 12 Organization of the khettaras in Tafilalet province. (Source: Thierry Ruf 2008, based on ORMVA-TF-SCET 1983. Plan directeur de mise en valeur agricole du Tafilalet Vol. No. 9, Rapport de synthèse) (See also Fig. 10.7 on p. 158)
344 Color Plates Plate 13 Population growth rates in the Southwest US (See also Fig. 14.1 on p. 222) Plate 14 The D1 and D2 curves used by the Rio Grande project (See also Fig. 14.6 on p. 233)
Color Plates 345 Plate 15 Visualizing groundwater pumping impacts (See also Fig. 14.7 on p. 235) Plate 16 Example of downscaled GCM projections for the US Southwest. The map to the left represents data at the GCM resolution. (Source: Cañon et al. 2008a) (See also Fig. 14.12 on p. 241)
346 Color Plates Plate 17 DSS results for 2010 and 2020 development scenarios. The arrows indicate the direction of change in riparian groundwater levels; the color of arrows indicates the magnitude of change. Red represents greater change, and green represents smaller change.
