“…Zhao suggested that water and energy systems can be important components of naturalsocial systems, which are driven by economic development, resource endowment, and the energy structure [49]. Jiang conducted a kernel density estimation to test the effects of an industrial matching index of water and land resources on the water-carbon relationship [50]. This research also confirmed that the economic output of water resources is the main contribution to land carbon emissions.…”

The water–energy–carbon (WEC) nexus is a complex, systematic relationship whose influential factors can be interdependent, as well as interactive. Although many action has been taken to achieve the goal of global carbon emission reductions, the disparity and unbalanced among water–energy–carbon systems hundles urban comprehensive development which can not be ignored. Therefore, investigating the water–energy–carbon (WEC) nexus become critical for the global. This study explores the relationship between water utilization, energy consumption, and carbon emissions systematically and take China, one of the largest global carbon emission countries in the world with high energy consumption and unevenly distributed water resources, as an example to investigate coupling coordination model. We selected 2004–2021 data from China’s 30 provinces as our research material, explored them using the entropy weight method, and attempted to study the coupling coordination level of the WEC nexus. Multiple linear regression (MLR) was used to identify the possible influential factors in the WEC nexus. In addition, Spatial correlation of the water-energy-carbon coupling coordination level in 31 provinces and cities has also been researched by Spatial Durbin Model(SDM). The results show that (1) in general, the level of WEC coupling coordination in China is increasing, and the spatial differences between different provinces are large; (2) the lowest level of WEC coupling coordination is mainly distributed in the central region, and the highest level is found in the southwestern region; and (3) water production and hydraulic engineering investment are important factors affecting the coupling coordination of the WEC nexus.

“…In the current context of carbon neutrality, water use and conservation measures are effective methods to reduce carbon emissions. The development of water resources as a clean energy source has made a considerable contribution to the implementation of decarbonization in the energy sector. − Water resources also face problems such as water pollution, water scarcity, wastage due to improper use of water, and ecological damage. , In the process of water pollution, the emerging pollutant selenium has attracted the general attention of modern scientists.…”

The emerging pollutant selenium has an immeasurable impact on production and life, and selective adsorption and effective utilization of excessive selenium in water bodies is very challenging. In this paper, nanoscale Al/Fe-MOF was obtained by in situ modification of Fe-MOF by Al 3+ , and Al/Fe-MOF-X/PAN nanofibrous membranes were prepared by combining with electrostatic spinning technology for the selective adsorption and enrichment of Se(IV) in water bodies. The adsorption experiments showed that the Al/Fe-MOF-2/PAN nanofibrous membranes had a high adsorption capacity and good selectivity for Se(IV), and the maximum adsorption capacity was up to 228.5 mg/g. The adsorption capacity of the adsorbent for Se(IV) in the actual water body was 220 mg/g. The five adsorption−desorption cycles demonstrated the multiple uses of the materials. X-ray photoelectron spectroscopy (XPS) confirmed that Se(IV) plays an important role in the anion exchange between the −OH in Se and Al species. This study is expected to shed light on the adsorption, enrichment, and transformation of selenium in real water bodies.

“…Figure 1 depicts a schematic diagram, illustrating the coupling mechanism between the four subsystems of WLEC: water, land, energy, and carbon emissions [5,14,26]. Simultaneously, practical studies are emerging in this domain [14,[26][27][28], encompassing research focused on agriculture and industry [29,30] highlighting excessive land resource input as a pivotal factor influencing agricultural carbon emission efficiency and excessive water resource input as a key determinant of industrial carbon emissions. Furthermore, relevant studies at the regional and watershed levels have been conducted.…”

“…While prior research has established a consensus on the interrelationships between water resources, land, energy, and carbon emissions [14], there remains a gap in studies examining the degree of integrated and coordinated development within these four subsystems and identifying potential obstacles. Currently employed methodologies include whole life-cycle assessment [31], energy analysis [32], the environmental input-output model [17,18,28,33,34], system dynamics, the LMDI model [30], flux observation and simulation [35], systems analysis [26]. However, limited attention has been given to constructing a comprehensive WLEC (Water-Land-Energy-Carbon) system safety development evaluation index, encompassing all aspects and processes to examine the coupling and coordinated development level of the water, soil, energy, and carbon subsystems, as well as their inhibiting factors.…”

The intricate interplay between water resources, land resources, energy systems, and carbon emissions has emerged as a prominent discourse in academic research. Nonetheless, there remains a dearth of comprehensive research dedicated to fostering environmentally friendly and low-carbon development through systematic integration and coordination efforts. This study aimed to fill this gap by integrating the coupling mechanism of the Water-Land-Energy-Carbon (WLEC) system, thereby constructing an evaluation index framework that assesses coordinated developments in Northwest China’s WLEC system. It scrutinizes the security levels within the Water-Land-Energy (WLE) subsystem while conducting quantitative analyses on the degrees of coupling coordination within the WLEC systems, alongside their associated hindering factors. The preliminary findings were as follows: Firstly, the safety development within the WLE system demonstrates a positive trend across Northwest China, with notable advancements primarily observed in the Qinghai and Gansu provinces. In 2021, all five Northwestern provinces exhibited moderate levels of safe development, except for the Qinghai province, which transitioned from moderate to robust. Secondly, the coupling coordination degree of the WLEC system across the five provinces has consistently illustrated an upward trajectory over the years. However, as of 2021, the system remains in a state characterized by marginal disorder. Notably, the Qinghai and Gansu provinces have shown particularly encouraging upward trends, with the Shaanxi province also making notable progress. Conversely, Xinjiang has declined since 2017 due to negative interactions between the subsystems of water, soil, energy, and carbon emissions. Thirdly, spatial variations exist in the distribution patterns between the provinces regarding the influence of obstructing factors on indicators related to coupled coordinated development, such as per capita arable land area, per capita energy consumption, per capita carbon emissions, per capita construction land area, and the proportion of groundwater water in the total amount of water supply, which demonstrated an increasing trend. These findings carry significant practical implications for actively and steadily promoting carbon peaking and carbon neutrality in Northwest China.
