Assessing the impacts of extreme precipitation on groundwater recharge under diverse hydrogeological conditions via the theis equation

Qingtao Ma, Xinghang Zhang, Zhijie Bai, Sishan Pang et autres

Climate change has amplified the frequency of extreme high-intensity precipitation events, altering groundwater recharge across diverse hydrogeological settings. Using observed precipitation, groundwater level (GL), hydrogeological drilling data, and the Theis equation, we quantified how precipitation affects groundwater in the Baiyangdian-Basin Plain. We …

Dietary differences amplify the water stress impacts of virtual water trade in the yellow river basin

Dandan Ren, Huiran Mao, D. X. Xiao, Yang Lu et autres

Understanding the implications of dietary consumption and food trade for water resources is essential for sustainable development in water-scarce regions. In this study, we quantified the dietary virtual water use (DVWU) and trade flows associated with food production and consumption across the …

Spatiotemporal Dynamics and Drivers of Agricultural Drought in the Huang-Huai-Hai Plain Based on Crop Water Stress Index and Spatial Machine Learning

Xiaoxia Hou, Na Li, Xia Zhang, Qingtao Ma et autres

Agricultural drought poses a critical constraint to food security and regional sustainable development, particularly in the Huang-Huai-Hai Plain, a major grain-producing region characterized by high spatial heterogeneity in drought risk. Previous studies have demonstrated that the Crop Water Stress Index (CWSI) outperforms …

Twenty-Year Variability in Water Use Efficiency over the Farming–Pastoral Ecotone of Northern China: Driving Force and Resilience to Drought

Xiaonan Guo, Meng Wu, Zhijun Shen, Guofei Shang et autres

Water use efficiency (WUE), as an important metric for ecosystem resilience, has been identified to play a significant role in the coupling of carbon and water cycles. The farming–pastoral ecotone of Northern China (FPENC), which is highly susceptible to drought due to …

Decoupling Driving Factors and High‐Precision Prediction of Food Security in Central Asia Based on a Coupled PLS‐SEM and PSO‐LSSVM Model

Qingtao Ma, Yonghui Yang, Zhijie Bai, Yanmin Yang et autres

ABSTRACT Grain supply and demand affect regional food security; however, the drivers are often unclear, making precise forecasting and policymaking challenging. This study used Central Asia as a case to integrate Partial Least Squares Structural Equation Modeling (PLS‐SEM) with particle swarm optimization …

Comparison of water-saving potential of fallow and crop change with high water-use winter-wheat – summer-maize rotation

Yanmin Yang, Yonghui Yang, Shumin Han, Huilong Li et autres

A land fallow system (LFS) designed to adjust the winter-wheat summer-maize cropping system to fallow summer-maize was introduced in Hebei Province to alleviate groundwater depletion in the region. However, some of the water saved was lost through evaporation from bare soil and …
