Faced with increasingly severe pressure on water resources, virtual water and virtual water trade theory provide a feasible solution to improve global water use efficiency for agricultural production and to alleviate the pressure on water resources in water-scarce countries or regions. The Yellow River, the second longest river in China, is facing...

In recent decades, China’s crop production experienced a spatial shift, and this shift may significantly influence the national water resources due to the geographical mismatch between water resources and cropland. By applying the widely applied AquaCrop model, this study quantified the impact of grain crop (rice and maize) expansion in northeaster...
Water is the most crucial input for agricultural production. Vagaries of monsoon and declining water table due to over exploitation of water have resulted in shortage of fresh water supply for agricultural use, which calls for an efficient use of this precious resource. In the background of shrinking water resources and competition from other secto...
Water is one of the most important natural resources and it is essential for human supply, industrial use, and agricultural production. Non-stationarity in historical flow series can indicate the approach of a water crisis or the occurrence of extreme events, which calls for measures to prevent worse scenarios. The objective of this study was to ex...
Water scarcity in Egypt leads to using all water resources, including reusing treated wastewater. The challenge facing us due to the usage of this resource is its contaminant loads of potentially toxic elements PTEs. One of the used technologies for removing these PTEs is sorption using sustainable adsorbent material, like cellulosic derived materi...

... Existing research has shed new light on the water supply and demand of the Yellow River regions from the perspective of virtual water (Cai et al. 2019;Song et al. 2022;Zhuo et al. 2022). However, limited attention has been paid to the displacement of groundwater resources between regions along the Yellow River Belt, which is currently a pressing issue of global concern (Majidipour et al. 2021;Schlattmann et al. 2022). ...
As a key industrial production base in China, Yellow River Belt regions are faced with immense pressure on their groundwater resources. Revealing the socio-hydrological dynamics of groundwater resources in the context of regional economic integration is essential for formulating sustainable water use. As an important aspect to reflect the socio-hydrological dynamics of regions along the Yellow River Belt, this study adopted a source-to-sink manner to quantitatively track regional groundwater use and the virtual groundwater transfer via domestic supply chains. The results indicated that the Yellow River Belt regions accounted for nearly a quarter of the national total groundwater use embedded in intraregional trades within China. It was found that regions along the Yellow River Belt primarily exported groundwater use to the Yangtze River Delta and South coastal region, with significant contributions coming from sectors such as chemical & mineral manufacturing, food & tobacco and agriculture. Water-deficient regions such as Inner Mongolia and Henan were revealed to supply substantial amounts of virtual groundwater use to other regions along the Yellow River Belt, exacerbating groundwater pressure in these areas that were scarce of water resources. These findings underline the importance of establishing intraregional and interregional cooperation mechanisms in coordinating water resources and economic development within the regions along the Yellow River Belt.
