“…Low mineralized water with a salt content of 1.0 g/cm 3 was used throughout the experiment. (Xu et al 2005a). Salinity sensors and tensiometers were installed at different depths (5, 20, 45, 70, 100 cm and then at an interval of 30 cm) through observation holes on the sides of the columns.…”

“…After evaluating several commonly recognized numerical methods (the high-order difference for derivative in time, the second-order upwind implicit scheme and the characteristic finite element method), it is concluded that the Galerkin-type finite element method is capable of overcoming the calculation difficulties. A detailed description of SWSTM's numerical solution can be found in Xu et al (2005a).…”

Salinization in a soil–water–plant system is an important environmental issue that has caused public concerns. In this study, field column experiments are conducted to study the transport of water and salt in soils affected by hydrologic circle and plant growth. A soil water and salt transport model (SWSTM) is developed and calibrated for predicting the behaviour of water and salt in a soil–water–plant system. The model takes into account water and solute uptake by crop roots and migration to groundwater. The experiment results demonstrate that the rise of the groundwater table enhances the movement of water and results in the accumulation of salt at a layer of 45 cm depth. With the decline of the groundwater table, the amount of accumulated salt increases correspondingly. The simulation results demonstrate that the SWSTM adequately predicts the water and salt transport in a soil–crop–plant system under different groundwater tables. The use of SWSTM will help to reveal the mechanism of water and salt transport in a soil–water–plant system. The SWSTM can also serve as a useful tool in evaluating the impact of agricultural activities and formulating efficient water management strategies in China.

“…The large water infrastructure exemplified by the south to north water diversion project (SNWDP) in BTH does contribute to groundwater recharge (Aeschbach‐Hertig & Gleeson, 2012; Kattel et al, 2019), reduces drawdown rate of the water table, improves GDEs and subsequently elevate water efficiency (Ye, Duan, Chu, Xu, & Mao, 2014). The selection of water‐saving irrigation technology and crop varieties is advised for soil conservation and sustainable use of groundwater in the region (Xu et al, 2005; Zou et al, 2011). Water conservation approaches such as the adoption of sprinkler irrigation, regulation of pumping restrictions (including restrictions on the diameter and depth of wells), construction of industrial waterworks, and regulation of water tax policies are important for groundwater recharging and water saving programs (Endo, 2015).…”

“…There are cases of increased groundwater contamination with nitrogen and heavy metals due to regional land use intensifications and related public health concern (Chen et al, 2007; Han, Currell, Cao, & Hall, 2017; Liu & Ma, 2020). Further, groundwater hydrology is influenced by seawater intrusion, riverbank habitat destructions across the coastal zones, which have triggered water shortage and environmental degradation with negative impact on socioeconomic development (Xu et al, 2005).…”

Healthy waterways and ecologically sustainable cities in Beijing‐Tianjin‐Hebei urban agglomeration (northern China): Challenges and future directions

et al. 2020

The cities across the northern dry region of China are exposed to multiple sustainability challenges. Beijing‐Hebei‐Tianjin (BTH) urban agglomeration, for example, experiences severe water shortages due to rapidly expanding urban populations, industrial use, and irrigation‐intensive agriculture. Climate change has further threatened water resources security. Overuse of water resources to meet the demand of various water sectors has far‐reaching health and environmental implications including ecosystem sustainability. Surface water and groundwater pollution present public health risks. Despite the extraordinary policies and efforts being made and implemented by the Government of China, the BTH region currently lacks coordination among stakeholders leading to poor water governance. Consultation among scientists, engineers and stakeholders on regional water security issues is crucial and must be frequent and inclusive. An international symposium was held in Shijiazhuang in early November 2019 to identify some of the key water security challenges and scope of an idealized future eco‐city in the region by developing a sustainability framework. This work drew on experiences from across China and beyond. Scientists agree that integration of science, technology, and governance within an appropriate policy framework was particularly significant for combating the issue of water insecurity, including in the region's newly developed city, Xiong'an New Area. An emerging concept, “Healthy Waterways and Ecologically Sustainable Cities” which integrates social, ecological and hydrological systems and acts as an important pathway for sustainability in the 21st century was proposed in the symposium to tackle the problems in the region. This high level biophysical and cultural concept empowers development goals and promotes human health and wellbeing. The framework on healthy waterways and ecologically sustainable cities can overcome sustainability challenges by resolving water resource management issues in BTH in a holistic way. To implement the concept, we strongly recommend the utilization of evidence‐based scientific research and institutional cooperation including national and international collaborations to achieve the Healthy Waterways and Ecologically Sustainable Cities goal in the BTH in future.

“…Over the years, the water-intensive economic development in northern China is hindered by severe water shortages [4,5]. The northern region, where more than 150 million people live, has faced a dramatic reduction as high as 150 billion m 3 of groundwater reserves over recent decade, causing a significant decrease in the water supply across Beijing, Tianjin and Hebei [6,7]. Groundwater reserves have played a vital role in protecting the environments against droughts over millennia [8].…”

China’s South-to-North Water Diversion Project Empowers Sustainable Water Resources System in the North

et al. 2019

Global freshwaters are severely depleted. Provision of improved water infrastructure technologies and innovation can address challenges posed by water shortages to environmental sustainability. China’s South-to-North Water Diversion Project has generated extensive debates over sustainability of water resources system in the northern drier region, which faces severe water scarcity hindering ecosystems, agriculture, industries and livelihoods. Some arguments extend the views that large infrastructure projects can have negative implications for biodiversity conservation and ecosystem goods and services. However, this study strengthens the opposite view, as such projects would resolve increasing environmental challenges northern China has been facing over many decades due to severe water shortages. The project empowers connectivity among individuals, community, and organizations that the sustainability of goods and services such as energy, irrigation and water supply are perceived, and livelihoods and the standard of peoples’ living is improved. A resilient, robust and adaptive water infrastructure framework can overcome the challenges of water shortages by meeting a long term social, economic and environmental goals for water resources systems in northern China. Such framework can also identify the thresholds of change and the threats associated with environmental sustainability.
