This study investigates the impact of climate variability on wheat production in Algeria’s semi-arid interior plains from 2014 to 2024, aiming curb challenges rainfed cultivation, optimize irrigation, and improve water productivity. The Soil–Water–Atmosphere–Plant (SWAP) model-driven approach refined irrigation scheduling mitigate climate-induced losses resource efficiency. Using historical data, soil properties, growth observations experimental farm Technical Institute for Field Crops, SWAP model was calibrated validated using one-factor-at-a-time sensitivity analysis, achieving a coefficient determination (R2) 0.93 Normalized Root Mean Squared Error (NRMSE) 17.75. Two drought-based indices, Soil Moisture Drought Index (SMDI) Crop Water Stress (CWSI), guided adaptive strategies, showing significant reduction crop failure during drought periods. Results revealed strong link between rainfall yield. Adopting 9-day interval could increase productivity 18.91 kg ha−1 mm−1, enhancing yield stability under varying climatic conditions. SMDI maintained moisture extreme drought, while CWSI optimized use normal wet years. integrates into framework, offering data-driven strategies enhance resilience. Findings support sustainable management provide practical insights policymakers farmers refine planning adaptation, contributing long-term agricultural sustainability.
