📊 Hydrological Balance & Sustainability Diagnostic Simulation Year: 2026

Geography Insight: In this hyper-arid climate (BW), natural rainfall recharge is nearly zero (<2 mm/yr). Farmland relies on deep fossil water extracted from ancient aquifers formed 20,000+ years ago. Current pumping exceeds recharge by 18x, causing steady water table drawdown and increasing soil salinization through intense surface evapotranspiration.
