“…The soil-specific factors played substantial roles in controlling metal behaviors in soils. The predominance of Pb (total and available) solely in the same PC affirms the unique behavior of Pb in the studied soils [53]. Results of the HCA agreed well with those of correlation and PCA.…”

Lack of active sorption sites in sandy soils renders metals added by irrigation water more labile and increases their soil-to-plant transfer. Thus, this study investigated the long-term impacts of irrigation using sewage effluents and contaminated groundwater on metal accumulations in TypicTorripsamment soils, and edible parts of food crops. Nine sites in El-Gabal El-Asfar farm, south-eastern to the Nile Delta of Egypt, were selected. At each site, irrigation water, soil (0–30 cm), and the crop’s edible part were sampled in triplicates and analyzed for Mn, Pb, and Zn. Results revealed significant (p < 0.05) differences in metal concentrations among water sources. Thus, constant irrigation caused significant spatial variations in total and available metal contents in soils. Total contents of Pb (in four sites) and Zn (in all sites) exceed the lithosphere range, while the available contents of the three metals exceeded the safe limits in all soils. The index of geo-accumulation indicated no Mn pollution but showed elevated pollution risks for Pb and Zn. The three metals showed high availability ratios, proving the effect of light soil texture. The multivariate statistical analysis indicated that Mn and Zn had similar geochemical behaviors in soils. Metal contents in all crop’s edible parts surpassed the safe limits. The bioaccumulation factor (BAF) was less than 1.0 for Mn and Zn but higher than 1.0 for Pb. The highest BAFs occurred in cabbage leaves, indicating the phytoextraction potential of this species. Sufficient water treatment and proper remediation techniques are recommended to alleviate metal accumulation in food crops and their transfer via the food chain.

“…In contrast to Ni concentration in irrigation waters, total Ni showed a significant 1.40-fold decrease and a slight 1.16-fold decrease in the ADW-and the SEW-irrigated soils compared with the control soils, respectively. These findings clarify that the accumulations of Cr, Co, and Ni in the studied soils were mainly governed by lithological factors rather than human intervention Jahin, 2019 and. The Cu content in the ADW-irrigated soils showed a slight 1.45-fold decrease compared with the control soils that interfered with the contents in irrigation water.…”

“…Similarly, the total Co contents in all soils exceeded the ANC in the earth's crust; however, the metal was not detected in irrigation water sources. Cr, Co, and Ni are common in ultramafic rocks (serpentine), which dominate the Nile Delta alluvial sediments (Abuzaid and Jahin, 2019). Total Co showed significant decreases of 1.47 and 1.50-folds in the ADW-and the SEW-irrigated soils compared with the control soils, respectively.…”

“…Statistical-based methods, including principal component analysis/factor analysis (PCA/FA) have been widely used to estimate the weights of parameters or indicators when developing an index [22,23]. The PCA/FA assumes linear relationships among the selected parameters [24]. However, non-linear relationships also occur among them [25].…”

Modelling land degradation vulnerability (LDV) in the newly-reclaimed desert oases is a key factor for sustainable agricultural production. In the present work, a trial for usingremote sensing data, GIS tools, and Analytic Hierarchy Process (AHP) was conducted for modeling and evaluating LDV. The model was then applied within 144,566 ha in Farafra, an inland hyper-arid Western Desert Oases in Egypt. Data collected from climate conditions, geological maps, remote sensing imageries, field observations, and laboratory analyses were conducted and subjected to AHP to develop six indices. They included geology index (GI), topographic quality index (TQI), physical soil quality index (PSQI), chemical soil quality index (CSQI), wind erosion quality index (WEQI), and vegetation quality index (VQI). Weights derived from the AHP showed that the effective drivers of LDV in the studied area were as follows: CSQI (0.30) > PSQI (0.29) > VQI (0.17) > TQI (0.12) > GI (0.07) > WEQI (0.05). The LDV map indicated that nearly 85% of the total area was prone to moderate degradation risks, 11% was prone to high risks, while less than 1% was prone to low risks. The consistency ratio (CR) for all studied parameters and indices were less than 0.1, demonstrating the high accuracy of the AHP. The results of the cross-validation demonstrated that the performance of ordinary kriging models (spherical, exponential, and Gaussian) was suitable and reliable for predicting and mapping soil properties. Integrated use of remote sensing data, GIS, and AHP would provide an effective methodology for predicting LDV in desert oases, by which proper management strategies could be adopted to achieve sustainable food security.
