Article
Full-text available
The increasing water use for human activities is threatening the health of ecosystems. Most previous studies on water scarcity mainly centered on human society. In this study, we developed a new indicator, ecological water scarcity (WSeco), that considers water quantity, water quality, and environmental flow requirements. WSeco was assessed at the...

Increasing agricultural water scarcity is threatening food security and ecosystem sustainability in China. Previous studies showed a deceleration in the growth of irrigation water use in China due to reducing water use intensities of irrigation. However, a finer-scale analysis at the prefecture level is urgently needed to account for the impacts of...
Article
Full-text available
Gallium oxide (Ga2O3), titanium dioxide (TiO2), cerium dioxide (CeO2), indium oxide (In2O3) and cadmium sulfide (CdS) were commonly used under UV light as photocatalysis system for the pollutants’ degradation. In this study, these five catalysts were applied for the photodegradation of perfluorooctanoic acid (PFOA), a well-known perfluoroalkyl subs...
Article
Full-text available
Increasingly growing consumption-based water use (WU) combined with climate change have exacerbated water stress globally and regionally, yet little is known about how the WU change is affected by metacoupled processes which involve human-nature interactions across space; within and across adjacent and distant places. This study aims to unveil the...
Article
Full-text available
With the increasing contradiction between water demand and supply in a telecoupled society where nature and human interplay intensively over distance, virtual water trade (VWT) plays an indispensable role in global water use sustainability. There has been little quantitative analysis of global water use sustainability depicting both overall system...
Article
Full-text available
Socioeconomic development has led to increased consumption of both blue and green water. Consequently, China is facing serious water scarcity issue. However, few studies have investigated interactions of blue and green water footprints, as well as driving forces underlying the changes in water footprints across provinces and sectors. To fill in thi...
Article
Full-text available
Since the 2030 Agenda for Sustainable Development being unanimously endorsed worldwide in 2015, how to achieve sustainable water security in accordance with Sustainable Development Goal (SDG) 6 targets has become a new measure of curbing water risk. In this study, the composite SDG 6 index (SDG6I) was developed exclusively on the basis of the SDG 6...
Article
Full-text available
Sustainable water management is one of the sustainable development goals (SDGs) and is characterized by a high level of interdependencies with other SDGs from regional to global scales. Many water assessment studies are restricted to silo thinking, mostly focusing on water-related consequences, while lacking a quantification of trade-offs and syner...
Article
Full-text available
A review and discussion on the water-food-energy nexus: bibliometric analysis The security of water, food and energy is a prerequisite for the 2030 Sustainability Development Goals of the United Nations. The increasing constraints and conflicts worldwide caused by water scarcity, energy shortages and food insufficiency have forced us to reflect on...
Article
Full-text available
Water footprint (WF) measures human appropriation of global water resources in volumes of consumptive use of surface and ground water (blue WF) and soil water (green WF), and of water required for assimilating the polluted water (grey WF). Questions have been often asked regarding the exact meaning behind the numbers from WF accounting. However, so...
Article
Full-text available
The well-known “virtual water hypothesis” states that water-deficient regions/countries could alleviate water stress through importing water-intensive products from water-abundant regions/countries. Although observed trading patterns do often not support this hypothesis, there is a lack of research to explore the reasons why trade patterns often do...
Article
A rapidly expanding economy and increasing water demand for agricultural and industrial production is placing enormous stress on water quantity and the aquatic environment in Northern China, especially the so-called Jing-Jin-Ji (Beijing-Tianjin-Hebei) urban agglomeration, home to over 110 million people producing 10% of China's overall GDP. Several...
Article
Full-text available
Demand for hydropower is increasing, yet the water footprints (WFs) of reservoirs and hydropower, and their contributions to water scarcity, are poorly understood. Here, we calculate reservoir WFs (freshwater that evaporates from reservoirs) and hydropower WFs (the WF of hydroelectricity) in China based on data from 875 representative reservoirs (2...
Article
Full-text available
Hydroelectric power is an important energy source to meet the growing demand for energy, and large amounts of water are consumed to generate this energy. Previous studies often assumed that the water footprint of hydroelectric power equaled the reservoir’s water footprint, but failed to allocate the reservoir water footprint among the many benefici...
Article
Full-text available
Globally, freshwater is a limited resource for human development. Social and economic development must consider water resources for sustainable development. With China忆s rapid economic development, renewable energy has been pushed to the forefront of the development agenda, and hydroelectricity is the most important renewable energy.However, hydroe...
