“…Freshwater is a fundamental and vital natural resource for the healthy existence of a sustainable ecosystem, society, and environment 1,2 since it is ubiquitously required for domestic, agricultural, and industrial day-to-day activities. 3 In the agriculture area, about 70% freshwater is needed for irrigation, fertilizer and pesticide applications, and sustaining livestock, which not only serves as a resource but also pollutes water bodies and soil as runoff of pesticides and fertilizers. 4 The demand for water in the future in all areas is expected to grow 25−40%, especially in water-stressed areas.…”

Worldwide water paucity and increasing food demand have stressed the agricultural sector for developing strategies to enhance quantity and quality of crop production with limited water resources. In order to pursue a solution of this demand, an efficient, resilient, sustainable, biodegradable, superabsorbent N−S−P carbon dots enriched carboxymethylcellulose nanohydrogel (CDs@CMC nanohydrogel) has been fabricated to study the growth pattern of Vigna radiata with limited water supply in a pot experiment. Characterization techniques like FTIR, TGA, and FESEM analysis established the morphology and structural characteristics of the prepared hydrogel. Sequential variation in the weight % of soil CDs@CMC nanohydrogel ratio was done to study the swelling ratio, water holding, and retention capacities of soil. Further, to ascertain their behavior as soil conditioners during plant growth, these were coupled with varying amounts of N−S− P carbon dots to give Gel-1, Gel-2, and Gel-3. The swelling ratios of Gel-1, Gel-2, and Gel-3 were found to be 2206%, 2582%, and 2712%, respectively, at pH 4, and their water holding capacities were calculated to be 36.7%, 39.5%, and 41.2%, respectively, with 1 wt % of each gel mixed with 50 g of soil, which is higher as compared to 50 g of soil alone (21.2%). The water retention time of the soil increased from 5 to 12 days with the soil mixed hydrogel at room temperature. The hydrogel remained intact, and their swelling capacity shows a slight decline after each consecutive water absorption−release cycle for ten cycles. Further, the seedlings grown in a potting mix containing Gel-1, Gel-2, and Gel-3 survived better than soil, but the best results were shown by Gel-2 with 1 wt % of hydrogel mixed with soil due to the incorporation of a suitable amount of N−S−P CDs in the hydrogel matrices. The ANOVA analysis is also applied for the optimization of the growth parameters of the growth pattern of Vigna radiata, and the study results are supported with the batch studies. Therefore, the environmentally safe, versatile N−S−P carbon dots enriched carboxymethylcellulose nanohydrogel holds promise for sustainable farming applications under water-limited conditions in arid and semiarid regions.

“…National and international research has made many useful explorations (Nie et al 2020;Wang & Han 2020;Wang et al 2020a), but the research has mostly stayed at the stage of conceptual framework analysis, and there are relatively few studies that draw specific service flow path diagrams (Báldi & Vári 2020;Gao et al 2020;Tong & Shi 2020). The University of Vermont in the United States proposed the Service Path Attribution Networks (SPANs) model within the Artificial Intelligence for Ecosystem Services (ARIES) project (Bagstad et al 2013).…”

Water security assessment is very important to social development. However, most studies only focus on the status quo of water security in a static state and ignore the flow characteristics of water resources into the water security assessment. This paper integrates multi-source data to construct a water supply and service supply-demand balance and spatial flow model in the Lianshui River Basin, simulates the spatial pattern of the service flow of the aquatic water ecosystem in the Lianshui River Basin from 1990 to 2018, and quantifies the service flow. Results show that (1) From 1990 to 2018, the water supply in the Lianshui River Basin first decreased, then increased, and finally decreased. Water yield was the highest in 2010 and lowest in 2000. (2) Water demand increased year by year, and the amount of area with a poor water resource security index increased, indicating that water security was deteriorating. (3) The four main beneficiary areas in the basin are the urban area of Lianyuan City, the county seat of Shuangfeng County, the Louxing District of Loudi City, and the urban area of Xiangxiang City and nearby towns. The service flow showed the same changing trend as the water yield. In 2018, the water resource gap in the beneficiary area was as high as 4.49 billion m3. Local governments should actively build a water-saving society, improve the efficiency of industrial and agricultural water-saving and residents' awareness of water-saving, and improve the water resources in the river basin. The research can provide a scientific basis for realizing the sustainable development of water resources in the Lianshui River Basin and improving the ecological compensation mechanism, and can also provide references for water resources management in other river basins.
