Water resource utilization and future supply–demand scenarios in energy cities of semi-arid regions

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Feb. 10, 2025

Analyzing the characteristics of water resource utilization and forecasting future supply–demand dynamics are great practical significance for planning allocation. This study focuses on challenges in energy cities located semi-arid regions, using Qingyang City as a case study. The demand various sectors was simulated projected, balance under different socioeconomic climate scenarios analyzed Shared Socioeconomic Pathways framework combined with model data. research addresses gap existing literature concerning analysis structures change provides scientific support regional sustainable development. results show that: (1) Over past 20 years, supply have exhibited significant growth trends, agricultural use continuously increasing, industrial fluctuating, domestic remaining stable, ecological growing significantly; (2) From 2024 to 2035, is projected substantially, being highly sensitive scenario configurations; (3) Under high economic scenarios, likely face severe shortages.

Multi-dimensional scaling for space-time transformation to achieve sustainable planning and management of water resource under changing land use pattern

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Jan. 7, 2025

The land use transition plays an important role for terrestrial environmental services, which had a mixed impact of positive and negative on the groundwater water resource. health ecological systems depends mapping management use. Ganga basin is one most densely populated agriculture-intensive river in South Asia world. multi-temporal spatial database includes (ESA-CCI), satellite-based gravity anomaly (GRACE/GRACE-FO), well log (CGWB) adopted this study assessment depth, drought, storage. methodology computation transition, trend magnitude by Sen's slope, Innovative Trend Analysis (ITA) graphical visualization, clustering techniques employ to identify pattern & structure, finally space-time transformation was assessed based multi-dimensional scaling using Alternating Least Squares Scaling (ALSCAL). over two decades shows increase forest (2.23%), wetland (2.2%), settlement (208.4%), bare area (3.18%), (5.18%), decrease agriculture (-1.16%), grassland (-4.5%), vegetation (-2.8%). non-parametric climatological loss maximally observed during post-monsoon season basin. seasonal statistics that, upper northern (left) alarming rate depletion, with increased severity drought near future ITA monotonic decreasing depicting resources. Bi-dimensional regression, ALSCAL that model efficient input data having stress value RSQ (proportion variance) 0.09 0.97 excellent linear fit. obtained low dimensional space showing conversion from sparse vegetation, agriculture, grassland, has maximum TWSA loss, although persistent also responsible. results are extremely useful policymakers, scientists, concern Govt. section, local communities must work together manage sustainably. Water resource can help lessen effects climate change focusing environmental, economic, social, institutional dimensions UN-SDG.

Analysis of water resources carrying capacity and obstacle factors in Gansu section of the Wei River basin using combined weighting TOPSIS model

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: April 14, 2025

Abstract Water resource carrying capacity is an important indicator for measuring sustainable development. Given the rapid economic and social development in China today, coordinating of water resources, socio-economy, eco-environment has become urgent problem to be solved. This study takes Gansu section Wei River mainstream basin (GWRB) as a case constructs three-dimensional WRCC evaluation system status standards. Based on this research framework, we analyzed trends changes GWRB from 2008 2022. Additionally, conducted in-depth internal relationships influencing factors within system. The results show that combination weighting method multi-weight models avoids one-sidedness single weighting, leading more realistic distribution weights. result standard derived prevents disconnect between status, making rational accurate. increased 0.098 (overloaded) 0.621 (weakly bearable) During period, eco-environmental improved critical bearable, while socio-economic overloaded weakly bearable. Due geographical climatic limitations, continued bear significant pressure remained state most time. key limiting further improvement are per capita utilization rate COD emission 10,000 yuan GDP, ecological use rate, consumption GDP agricultural rate. To improve WRCC, propose series targeted recommendations based findings. proposed framework can also serve reference related studies arid semi-arid regions.
