英文摘要Investigating processes causing water resource depletion risks is key to understanding past, present, and future excessive irrigation water withdrawal. Quantitative spatiotemporal analysis of the factors driving excessive irrigation water withdrawal is currently inadequate. Although multiple drivers typically contribute to this risk, we studied, for the first time, whether and how Actual Irrigation Water Withdrawals (AIWW) could affect global future water resources projection. Here, we used AIWW datasets from five CMIP6 climate models based on two Shared Socioeconomic Scenarios (SSP370 and 585) and a global hydrological model (H08) to compare the historical (1981-2014) with the future periods: 2041-2070 and 2071-2100. Results show that the temporal AIWW average variations have shown a statistically significant increase during 1981-2014 (p<0.05 and R-2 = 0.98) ranging from 101.82 to 136.24 mm yr(-1) (mean = 120.5 mm yr(-1)). Under SSP370 and SSP585, the global spatial AIWW average during 2041-2070 and 2071-2100 are 142.55 and 145.55, and 144.91 and 149.74 mm yr(-1), respectively. Under SSP370 and SSP585, the average AIWW changes for 2041-2070 and 2071-2100 are projected to be 96.71, 97.55, 103.52, and 106.98 %, respectively. Under SSP370 and 585, the average global AIWW anomaly changes for 2041-2070 and 2071-2100 are also projected to be -96.86, -106.29, -97.72, and -111.48 %, respectively. Higher AIWW increases are mainly concentrated in India, South China, parts of the United States, parts of Europe, and parts of South African and Latin American countries. Substantiated with population increase, and higher food demand, an increased AIWW will further aggravate globally. Thus, exploring future AIWW changes is a key step forward that requires greater attention in irrigation research interventions helpful to inform societies to reduce future risks of water resource depletion. Adaptation policies targeting the future use of water for irrigation are crucial to lessen water resource depletion risk, suggesting the need for large-scale policy interventions.
