Water rights trading is an important way to solve the shortage of water resources. Combined with the characteristics of water resources and the requirements of the market economy, the organic combination of the government and the market should be strengthened. Through the establishment of a water rights system and a water rights trading market, the implementation of water rights trading will be promoted. Due to the decentralized and distributed structure, blockchain technology greatly reduces its intermediary cost in the application process. The tamper-resistant timestamp feature can realize data tracking and information anticounterfeiting, and flexible programming attributes can promote the specification of market order. Firstly, the reasons for water rights trading are studied, and the water rights trading system is analyzed. It is found that the system has the problems of the cumbersome transaction process and high transaction costs. According to the characteristics of water rights trading, the alliance chain Hyperledger Fabric is selected as the underlying network system of the trading system. Secondly, combined with water rights trading, Hyperledger Fabric multichannel technology is used to design a three-channel accounting method, and the chain code for water rights trading is designed and implemented based on the Go language. CouchDB is adopted to store key-value data, and Ubuntu, Docker, and Docker Compose are used to construct an operating environment of the chain code. Finally, the proposed system is tested. The test findings reveal that the distributed water volume of experimental area 1 is 41.8368 million m3, the current water volume is 23.831 million m3, and the quota management water volume is 20.432 million m3. The distributed water volume in area 2 is 40.4605 million m3, the current water volume is 4317.64 m3, and the quota management water volume is 77.4795 million m3. The distributed water volume in area 3 is 65.6928 million m3, the current water volume is 77.472 million m3, and the quota management water volume is 64.412 million m3. The water rights trading system based on Hyperledger Fabric can record each transaction data, which can be stored in each node, and the data stored in each node are the same. The proposed scheme provides a certain reference for the application of blockchain technology in water rights trading in irrigation areas.

“…Hence, the water requirement or the gross irrigation requirement (IR g ) was estimated at 619, 628 and 608 mm during the season I, II, III respectively, with an average value of 618 mm. Positive response of drip fertigated potato from 60-100% ET c is observed by Shaohui Zhang et al (2022). An effective rainfall (P eff ) of 96, 126, and 120 mm respectively was received during the three cropping seasons.…”

Present study was carried out at the research farm of ICAR-Central Tuber Crops Research Institute, Thiruvananthapuram, Kerala during 3 summer seasons of 2016–17, 2017–18 and 2018–19 to assess the crop water requirement of upland taro (Colocasia esculenta L. Schott) and to arrive at a suitable irrigation schedule under humid tropical conditions of Kerala. The experiment was conducted in randomized block design (RBD), with 7 treatments as 5 levels of drip irrigation, [50% (I1), 75% (I2), 100% (I3), 125% (I4) and 150% (I5) of the crop evapotranspiration, ETc], furrow irrigation and a rainfed crop with 3 replications. Crop water requirement was calculated as same as crop evapotranspiration (ETc) assuming that there is no other water losses. Pooled analysis of the data collected for three seasons indicated that, I3, drip irrigation at ETc 100% is optimum for achieving maximum cormel yield and optimum water productivity. The optimal water requirement for upland taro was observed as 610–628 mm, including effective rainfall, based on the crop, soil and climatic parameters. The information will support the farmers to develop irrigation plans in advance during summer season, and for ensuring effective usage of irrigation water in water scarce areas, in this era of climate change.

“…In contrast, the high concentration of K in plants irrigated with TWW may have also contributed to produce the differences found in grain yield, forage yield, LAI, and CCI. Accordingly, Zhang et al [ 87 ] reported a significant interaction between K, LAI, and CCI in potatoes ( Solanum tuberosum ). According to the authors, a high concentration of K promoted high tuber yield and quality, which agrees with our findings.…”

The use of treated wastewater (TWW) for irrigation has gained global attention since it reduces pressure on groundwater (GW) and surface water. This study aimed to evaluate the effect of TWW on agronomic, photosynthetic, stomatal, and nutritional characteristics of barley plants. The experiment with barley was established on two bands: one band was irrigated with GW and the other with TWW. The evaluation was performed 25, 40, 60, 90, and 115 days after sowing (DAS). Results showed that irrigation with TWW increased (p < 0.01) grain yield by 54.3% and forage yield by 39.4% compared to GW irrigation. In addition, it increased plant height (PH) (p = 0.013), chlorophyll concentration index (CCI) (p = 0.006), and leaf area index (LAI) (p = 0.002). TWW also produced a positive effect (p < 0.05) in all the photosynthetic efficiency parameters evaluated. Barley plants irrigated with TWW had lower stomatal density (SD) and area (SA) (p < 0.001) than plants irrigated with GW. Plants irrigated with TWW had a higher P concentration (p < 0.05) in stems and roots and K concentration in leaves than plants irrigated with GW. We concluded that the use of TWW induced important biochemical, physiological, and agronomic changes in barley plants. Hence, the use of TWW may be a sustainable alternative for barley production in arid and semi-arid regions. This study was part of a government project, which aimed to develop a new metropolitan irrigation district with TWW. This study may contribute to the sustainability of water resources and agricultural practices in northern Mexico.
