Studies in recent decades have demonstrated that artificial neural networks possess strong capabilities for modeling complex and nonlinear systems. This research investigates the applicability of radial basis function (RBF) and multilayer perceptron (MLP) neural networks for determining land suitability. Data from 300 soil profiles located in a northern agricultural plain were used. The evaluated parameters included soil texture, pH, EC, ESP, CaCO₃ content, gypsum content, soil depth, topography, groundwater depth, and segment depth. Land suitability classes were initially determined using the FAO classification method. These values were used as target outputs for training neural networks with various structural configurations. Of the total dataset, 69% was used for training and 31% for testing. Next, the trained neural networks were applied to predict land suitability classes using the unseen portion of the data (31%). A comparison of the two neural network models revealed that the MLP network produces more accurate predictions of land suitability classes than the RBF network. Additionally, the MLP model required less training time compared to the RBF model. These results indicate that MLP neural networks offer superior performance for land suitability estimation.

In recent years, climate change and recurring drought events in Algeria have caused increasing variability in rainfall patterns and heightened pressure on already-limited water resources. This imbalance between water availability and demand has resulted in reduced precipitation and adverse effects on both economic activity and community livelihoods. The province of Mostaganem, characterized by a semi-arid climate, suffers from particularly constrained water resources. Agriculture accounts for approximately 74% of total water consumption in the region, yet much of this water is used through outdated irrigation techniques that result in significant inefficiencies and waste. Irrigation water is predominantly drawn from small and medium hydraulic (PMH) systems and uncontrolled wells. As agricultural demand relies heavily on groundwater, overexploitation has led to a notable decline in aquifer levels, threatening the long-term viability of the province’s water supply. This study provides a diagnostic assessment of current irrigation practices, with the aim of identifying inadequacies and proposing measures to support water conservation and improve irrigation efficiency. The observed overexploitation of groundwater has already reached a critical level, posing a risk to future agricultural sustainability. However, with the implementation of targeted policies and interventions aimed at promoting rational water use, it is expected that local water management authorities will be better positioned to meet growing agricultural demands.
