摘要

Over 1.8 billion people worldwide face water scarcity threats, with the challenge particularly acute in densely populated and agriculture-intensive drylands. Northern China, among the world’s most water-stressed regions, faces an intensifying yet poorly understood imbalance between freshwater supply and consumptive demand. Here, we reveal a sustained decline in terrestrial water storage (TWS) in recent decades (2004–2022) at −9.15 ± 1.24 Gt/yr. Although climate change delivers substantial water gains (+12.44 Gt/yr), irrigation consumption (−16.16 Gt/yr) overwhelms these climate-driven water gains and dominates regional water depletion. Industrial and domestic water use contribute an additional −4.43 Gt/yr, while large-scale ecological restoration inadvertently amplifies water losses through vegetation-driven enhancement of evapotranspiration (−0.91 Gt/yr). Future projections indicate that under the intermediate and high emission scenarios, TWS will continue declining through mid-century (2041–2060), with supply-demand gaps widening by 65% and 120%, respectively. These findings reveal an anthropogenic water management crisis and highlight the urgency of systemic interventions to avoid escalating water risks.
