“…[5] explored the spatiotemporal evolution of the matching characteristics of water and soil resources in farmland under different crop growth stages from the perspective of the supply and demand of farmland water resources. In addition, some scholars have studied the matching of water and soil resources from the perspective of the water footprint [22]. Ref.…”

The coordinated development of water and soil resource matching and grain production is essential to enhance integrated grain production capacity and promote sustainable development in agriculture. Based on the perspective of a water footprint, this article empirically evaluates the coupling coordination relationship between water and soil resource matching and grain production in typical black soil areas in Northeast China using the coupled coordination degree and the obstacle model and further analyzes the obstacle factors that affect the coordination between the two systems. The results indicate that the blue water footprint, green water footprint, and total water footprint of five grain crops are increasing year by year. Soybean has the largest water footprint per unit mass, tubers have the smallest, and rice has the largest water footprint among cereals. The overall matching degree of water and soil resources in the study area is steadily increasing. However, there are significant differences in the water and soil resource matching coefficients between regions, with the highest being observed in Hegang City and the lowest being observed in Jiamusi City. Coupling remains at a high level and coupling coordination shifts from a low–middle–high to a middle–high stage. The correlation between soil and water resource matching and grain production systems is of significant importance. The degree of matching between water and soil resources serves as the primary obstacle affecting the coupling and coordinated development of integrated systems, which fundamentally restricts the sustainable development of regional agriculture.

“…Among them, the Yellow River basin [11], the northeastern region [12], and typical mountainous areas have substantial research results. The measurement methods mainly include the unit area water resource method [13], the Gini coefficient method [5], and the water footprint method [14]. Among these methods, the unit area water resource method is widely used because it can intuitively reflect the matching degree of regional agricultural water and land resource endowment.…”

Improving the coupling coordination degree between water and land resources matching (WLRM) and cultivated land use eco-efficiency (CLUE) is crucial to ensuring national food security and constructing an ecological civilization. This study is based on the data of 71 prefecture-level cities in the major grain-producing areas in the middle and lower reaches of the Yangtze River from 2008 to 2020. The unit area water resource method, the slacks-based measurement (SBM)-undesirable, the Theil–Sen median analysis, the Mann–Kendall trend test, the coupling coordination degree model, and the spatial autocorrelation model are adopted to measure and analyze the WLRM, the CLUE, and the coupling and coordination level, and their spatial–temporal evolution characteristics quantitatively. Results show the following: (1) From 2008 to 2020, the average value of WLRM in the study areas is 18,200 m3/hm2, which is at a medium level, and the provinces show the characteristics of “high in the south and low in the north, with decreasing gradients”. (2) The annual average of CLUE is 0.777, which is in the medium level, and each province has the remarkable characteristics of “one high and four low”. (3) The coupling coordination degree of WLRM and CLUE is in the primary coordination level, which shows a significant positive correlation in space. In the local perspective, it shows the agglomeration characteristics of “high in the south and low in the north, nodule distribution”. In the future, the neighboring prefecture-level cities should actively build a synergistic mechanism for agricultural development, strengthen the reasonable use of water and land resources and pollution control techniques, drive the transformation of low–low aggregation areas to high–high aggregation areas, and improve the overall coordination of the study areas. This approach aims to promote the construction of ecological civilization and guarantee grain security and sustainable development of agriculture in China.

“…The concept of the ecological footprint (EF) was proposed by William and introduced by Wackernagel in the field of assessing water resources [13,14]. The current research on EF W has concentrated on industrial production [15][16][17][18][19][20] and agricultural security [21][22][23][24], whereas quantitative assessments of urban water security are lacking [25]. However, the problem of water loss and polluted water have received increasing attention, which have made water companies, politicians, urban planners and other stakeholders use the concept of the ecological footprint of water to determine the direction of investment and policy implementation.…”

An Evaluation of the Sustainability of the Urban Water Resources of Yanbian Korean Autonomous Prefecture, China

The availability of water resources is crucial to maintaining the sustainability of urbanization. Calculating the ecological footprint of water (EFW) is one of the ways to realize the protection of water resources in the process of urbanization. The minor settlements in border areas have been the focus of China’s urbanization development but have rarely received research attention. The objective of this study was to develop an improved model of the ecological footprint of water (EFW) to assess the water security status of urban areas in Yanbian Korean Autonomous Prefecture (YKAP), and to demonstrate its authenticity compared with the traditional ecological footprint of water (EFW). The results showed that water pollution is the main reason for the increase in the EFW in each city, and the ecological water carrying capacity (ECW) showed strong fluctuations with the interannual variation in precipitation. Although the overall availability and quality of water resources are within safe limits, there are significant differences among cities, and water pollution poses a direct threat to the health and well-being of urban dwellers in some cities. Therefore, it is recommended that water resource management agencies adjust their water supply strategies based on the data from the EFW model, control wastewater discharge, improve their management systems and take urban economic development into account. This will significantly improve the sustainable management of water resources and ensure the health and well-being of urban residents.
