Accurate monitoring of soil salinization plays a key role in the ecological security and sustainable agricultural development arid regions. As branch artificial intelligence, machine learning acquires new knowledge through self-learning continuously improves its own performance. The purpose this study is to combine Sentinel-2 Multispectral Imager (MSI) data MSI-derived covariates with measured salinity apply three algorithms modeling estimate map sample area. According convenient transportation conditions, area sampling quadrat were set up, 5-point method was used collect mixed samples, 160 samples collected. Kennard–Stone (K–S) algorithm for classification, 70% 30% verification. uses Support Vector Machines (SVM), Artificial Neural Network (ANN), Random Forest (RF). results showed that (1) average reflectance each band MSI ranged from 0.21–0.28. spectral characteristics corresponding different electrical conductivity (EC) levels (1.07–79.6 dS m−1), salinized 0.09–0.35. (2) correlation coefficient between EC moderate, certain sets not significant. (3) SVM estimation model established attained higher performance accuracy (R2 = 0.88, root mean square error (RMSE) 4.89 m−1, ratio interquartile range (RPIQ) 1.96, standard laboratory measurements predictions (SEL/SEP) 1.11) than those models RF ANN models. (4) We applied area, which farmland altitudes discharged large amount salt surroundings due long-term irrigation, secondary also caused accumulation. This research provides scientific basis simulation scenarios areas future.

Gully erosion is a serious threat to the state of ecosystems all around world. As result, safeguarding soil for our own benefit and from actions must guaranteeing long-term viability variety ecosystem services. developing gully susceptibility maps (GESM) both suggested necessary. In this study, we compared effectiveness three hybrid machine learning (ML) algorithms with bivariate statistical index frequency ratio (FR), named random forest-frequency (RF-FR), support vector machine-frequency (SVM-FR), naïve Bayes-frequency (NB-FR), in mapping GHISS watershed northern part Morocco. The models were implemented based on inventory total number 178 points randomly divided into 2 groups (70% used training 30% validation process), 12 conditioning variables (i.e., elevation, slope, aspect, plane curvature, topographic moisture (TWI), stream power (SPI), precipitation, distance road, stream, drainage density, land use, lithology). Using equal interval reclassification method, spatial distribution was categorized five different classes, including very high, moderate, low, low. Our results showed that high classes derived using RF-FR, SVM-FR, NB-FR covered 25.98%, 22.62%, 27.10% area, respectively. area under receiver (AUC) operating characteristic curve, precision, accuracy employed evaluate performance these models. Based (ROC), RF-FR achieved best (AUC = 0.91), followed by SVM-FR 0.87), then 0.82), contribution, line Sustainable Development Goals (SDGs), plays crucial role understanding identifying issue “where why” occurs, hence it can serve as first pathway reducing particular area.
