Results of calculations and forecast of water consumption in the Dongnai River (Vietnam) for the period till 2020 are discussed. The analysis, the water regime forecast and water consumption optimization are considered the basis for sustainable water use formation and attaining of water resources use effectiveness in the Vietnam’s national economy providing securing of environmental safety, particularly, necessary hydrological conditions for preservation of the mangrove forest ecosystem of the «Kanzio» specially protected natural territory near the river’s mouth.

As a result of the study, it was proved that the existing water resources management system, which is built on the component, territorial-branch principle, causes extremely high and unacceptable economic, social and environmental costs at the present stage of human development. An alternative paradigmatic concept of forming an integrated water resources management system in Ukraine is proposed based on the basic provisions of the theory and methodology of neo-institutionalism. The main directions of organization of the institutional architecture of water resources management in the context of providing sustainable water use are determined.

The article focuses on the current topic of public water resources management. Globalization presents new challenges and demands for sustainable development for society. The current problem of modern humanity is the rational use of limited water resources. Water management is closely linked to the harmonization of social, economic and environmental requirements. The domestic water use system cannot meet European requirements for effective water supply due to moral and physical wear. An inadequate regulatory framework reduces the effectiveness of management processes and requires finding ways to attract investment to the industry, including in public-private cooperation. The analysis of the main problems of water management development, including non-compliance with European standards, moral and physical wear, lack of effective systems of water resources planning, monitoring and control of use of water resources, showed that these problems are primarily the result of an imperfect system of public water management. Based on commercialization processes, the water supply system through the implementation of public-private partnership mechanisms, provided that private entities are clearly monitored by public authorities, can produce significant socio-economic and environmental results. The research developed an algorithm for implementing an effective water management system at the state level by developing and implementing public-private partnership projects in accordance with the requirements of an effective water management system. The mathematical model of information and analytical support of processes of monitoring of rational water use in conditions of implementation of public-private partnership projects is defined.

Due to the rich resources of urban rainwater and transit flood in coastal areas, rational utilization of rainfall and flood water resources can improve the sustainable utilization, to better serve the coastal development. In this paper, the available quantity of water rainfall and flood water resources in coastal are distributed to domestic water, industrial water, agricultural water and ecologic environmental water. Water price method is used to calculate domestic water efficiency. Energy synthesis is used to calculate the industrial and agricultural water-use efficiency. Ecologic environmental water-use efficiency-sharing coefficient method is used to calculate the ecologic environmental water-use efficiency. Finally, taking Lianyungang City, a Jiangsu coastal city as an example to analyze the rainfall and flood water resources utilization efficiency. The results provide reference to the research for Chinas plain area rainfall and flood water resources efficiency analysis.

Introducing alternative cultivars with enhanced water use efficiencies can help alleviate pressure on groundwater for crop irrigations in Mississippi (MS) Delta. A two-year field study was conducted in 2019–2020 to compare the water use efficiencies (WUE) of recently released and pre-released soybean {Glycine max (L.) Merr.} cultivars in maturity group (MG) III (‘P37A78’, ‘LG03-4561-14’), IV (‘Dyna-gro 4516x’, ‘DS25-1, DT97-4290’), and V (‘S12-1362’, ‘S14-16306’) in the MS Delta. The experimental design was a split-plot with cultivar as the first factor and the second factor was water variant irrigation (IR) and no irrigation (RF, rainfed), replicated three times. The MG IV cultivar Dyna-gro 4516x recorded the highest grain yield and WUE: grain yields were 4.58 Mg ha−1 and 3.89 Mg ha−1 under IR and RF, respectively in 2019, and 4.74 Mg ha−1 and 4.35 Mg ha−1 in 2020. The WUE were 7.2 and 6.9 kg ha−1 mm−1, respectively, in 2019 under IR and RF, and 13.4 and 16.9 kg ha−1 mm−1 in 2020. The data reveals that ‘Dyna-gro 4516x’ (MG IV), ‘LG03-4561-14’ (MG III), and ‘P37A78’ (MG III) are best adapted to the early soybean production system (ESPS) in MS Delta region for sustainable production for conserving water resources.

The sustainable and efficient use of water resources has gained wide social concern, and the key point is to investigate the virtual water trade of the water-scarcity region and optimize water resources allocation. In this paper, we apply a multi-regional input-output model to analyze patterns and the spillover risks of the interprovincial virtual water trade in the Yellow River Economic Belt, China. The results show that: (1) The agriculture and supply sector as well as electricity and hot water production own the largest total water use coefficient, being high-risk water use sectors in the Yellow River Economic Belt. These two sectors also play a major role in the inflow and outflow of virtual water; (2) The overall situation of the Yellow River Economic Belt is virtual water inflow, but the pattern of virtual water trade between eastern and western provinces is quite different. Shandong, Henan, Shaanxi, and Inner Mongolia belong to the virtual water net inflow area, while the virtual water net outflow regions are concentrated in Shanxi, Gansu, Xinjiang, Ningxia, and Qinghai; (3) Due to higher water resource stress, Shandong and Shanxi suffer a higher cumulative risk through virtual water trade. Also, Shandong, Henan, and Inner Mongolia have a higher spillover risk to other provinces in the Yellow River Economic Belt.
