“…In previous studies, various areas that were susceptible to degradation and desertification were identified, most of them due to climate changes that cause frequent dry events such as those in the Dobrogea Plateau and the eastern Romanian Plain [68,69], and in other areas due to soil erosion and landslides such as those in the Moldavian Plateau [70,71] and some areas in the Transylvanian Depression [72,73]. Also, soil erosion was identified in various areas of the Dobrogea Plateau [74], a phenomenon potentiated by overgrazing [75,76].…”

“…The values were very close to those obtained in this study (7.76% of the total area of Romania was LD, 60.8% of the total area tended to improve, and 31.44% was stable), in which the PCA was used to aggregate remote sensing indices into a single LDM. It is very likely that the differences between the results were due to the length of the analysis period In previous studies, various areas that were susceptible to degradation and desertification were identified, most of them due to climate changes that cause frequent dry events such as those in the Dobrogea Plateau and the eastern Romanian Plain [68,69], and in other areas due to soil erosion and landslides such as those in the Moldavian Plateau [70,71] and some areas in the Transylvanian Depression [72,73].

Land degradation (LD) and desertification (DS) are a sensitive global issue including southern and south-eastern Europe, which is severely affected by climate change. In this study, a state-of-the-art approach for assessing the intensity of LD and DS processes using remote-sensing-derived indicators within a GIS environment was proposed. The analysis was carried out using the Principal Component Analysis based on integrating the significant trends of relevant biophysical parameters in Romania. The methodology was tested and validated at the national level in Romania. In total, 7.76% of the area was identified as LD and 60.8% of the total area tended to improve, and 31.44% was stable. Most of the regions with LD overlapped with the dryland areas, while improvement areas were identified outside of the drylands. In forested areas from high altitudes, a tendency to improve the condition of vegetation was observed, and most of the surfaces being protected were natural areas that have benefited from proper management. All these results can be used to adapt management practices to avoid, reduce, or restore the LD. The proposed model was based on globally available remote sensing datasets, with a high frequency of data acquisition and collection history that allows for the statistical analyses of changes on a global scale.

The Southern Mehedinți Plateau and Iron Gates grasslands from Romania, from a phytosociological point of view, belong to the Festuco-Brometea class with xerophilous vegetation. They are spread over an altitudinal difference of 70-630 m in the Mehedinti Plateau and 70-320 m at the Iron Gates, with the Danube River as the lower limit. They are mostly located on average slopes of 31 degrees of inclination, on sunny exposures. In the grassy carpet, on average, 81 species of cormophytes were recorded in the 12 phytosociological associations, of which Danthonio-Chrysopogonetum grylli with 155 species and Fumano - Stipetum (eriocaulis) praemoesicum with 110 species are distinguished. The average degree of vegetation cover is 70%, of which 20% are forage species and 50% harmful species, with no forage value. Average production of green mass production is 2.42 t/ha, with variation from 1.46 t/ha in the associations in the south of Mehedinți Plateau, to 4.32 t/ha at Iron Gates. The grasslands productivity in the area taken in the analysis is lower than in Dobrogea, respectively, by 68% for the green mass production and barely 39% for the pastoral value. As a result, the cow's milk production possible to obtain in Dobrogea is 2,720 litters/ha, 254% higher than that of the analyzed area, where it is estimated a milk production of 1,070 litters/ha in 160 days of the optimal grazing season. These data on the grasslands production and quality further serve to draw up the pastoral arrangements and grasslands management.
