However, environmental concerns associated with reservoir development are becoming more evident. For instance, the stored water is gradually becoming saline. Studies suggest that reducing water evaporation over extended periods can effectively lower the salt concentration in the water. Currently, there is limited research on salt migration in reservoir water when covered with anti-evaporation materials. Given the potential impact of these materials on the water environment and hydrodynamic conditions, this study seeks to examine the spatiotemporal distribution patterns of reservoir mineralization under such covering. To this end, laboratory and field experiments were conducted to analyze the impact of covering the water surface with floating high-density polyethylene spheres to reduce evaporation and its effect on water salinity. These experiments included monitoring water temperature, dissolved oxygen, pH, sediment resuspension, and water conductivity, as well as calculating the contribution of sediment release and evapotranspiration to the increase in salinity concentration within the water column. This study investigates the role of floating high-density polyethylene (HDPE) spheres in reducing reservoir evaporation and mitigating water salinity. Laboratory and field experiments assessed the effects of different coverage levels (0 %-74.98 %) on evaporation rates, sediment resuspension, and water chemistry. The findings indicate that covering 74.98 % of the reservoir surface led to a 28.97 % reduction in salinity (p &lt; 0.05) over one irrigation cycle. Evaporation inhibition varied from 13.56 % to 60.19 %, depending on coverage. However, floating spheres exhibited reduced effectiveness at high wind speeds (&gt;10.7 m/s), highlighting the need for additional containment strategies. Future research should explore long-term durability, ecological impact, and cost-effectiveness of large-scale deployment.</div></div>","PeriodicalId":7634,"journal":{"name":"Agricultural Water Management","volume":"312 ","pages":"Article 109440"},"PeriodicalIF":5.9,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143724032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From the \"catfish effect\" perspective in financial markets, this study uses data from 286 prefecture-level cities in China between 2011 and 2022. It applies a two-way fixed effects model and a threshold effect model to empirically test the mechanism of digital inclusive finance (DIF) in promoting AITI. The results show that DIF significantly boosts AITI. Mechanism testing reveals that this effect is driven by the \"catfish effect\" in financial markets. This effect not only increases the credit availability for innovation entities but also reduces financing costs, thereby fostering technological innovation in alternating irrigation. However, the heterogeneity analysis indicates that this effect varies due to differences in the funding sources for R&amp;D. The impact is more significant for enterprise-type innovators, while it is not significant for individual and research institution innovators.

By contrast, unplanned water use is the unauthorized extraction of groundwater, river water, or lake water. Although unplanned water use may be a major contributor to ecological problems, estimating unplanned water use has been a challenge due to the lack of comprehensive data on unplanned water use in the relevant sectors. This study evaluated unplanned water use in the northern slope of the Tian Mountains in Xinjiang, considering the overall water use situation of various industries based on system dynamics. The results showed that unplanned water use has increased rapidly, mainly due to rapid expansion of cropland and limited growth in planned water use. The proportion of unplanned water use of all water use reached a maximum proportion of 35.2 % in 2020. This phenomenon should be attracted attention from various sectors of society.

In this article we propose a practice-based approach to research scaling that can help unpack the complexity of change, by focussing on everyday practices. We applied this approach by researching the scaling up of controlled drainage with subirrigation (CD-SI), which is an alternative water management practice being trialled out in the high-lying sandy soils of the Netherlands. The research uses a combination of interviews, participant observation and a limited literature review as the methodology. In analysing the network of practices, with CD-SI systems as the key material aspect of the novel water management practice, the mechanisms that underpin the possible scaling of CD-SI have been identified. The CD-SI system integrated quite easily into the everyday practices of farmers, yet questions about water access and use remain crucial to the scalability of CD-SI systems. The CD-SI systems were investigated as they were thought to be more sustainable in water use, yet this research concludes that there is limited reconfiguration of everyday water management practices with the introduction of this new material element. Discussed in brief, we conclude that the practice-based approach has proven to be a useful addition to the various approaches to scaling research.</div></div>","PeriodicalId":7634,"journal":{"name":"Agricultural Water Management","volume":"312 ","pages":"Article 109451"},"PeriodicalIF":5.9,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143704709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, how root tip morphological adjustments—a critical control point for belowground water acquisition—mediate warming-induced ET intensification remains unresolved at the ecosystem scale, particularly across the Qinghai-Tibet Plateau (QTP) where these processes govern regional hydrological sustainability. This study employed a five-year field experiment using open-top chambers along an altitude gradient in central QTP, used root morphology parameters such as root tip density (RTD) as an entry point to explore the morphological characteristics of the root system under climate change, and improved the root water uptake model based on the distribution function of RTD to analyze the effects of warming on the water uptake pattern and transpiration characteristics of the root system of alpine meadow on the QTP. Key findings revealed that: (1) Root morphological adaptation: Increasing temperature promotes the growth of root in alpine meadows. About 80 % of the roots are distributed in the 0–25 cm soil layer, and the RTD first increases and then decreases with the increase of soil depth. (2) Altitude-specific water uptake: In lower altitude areas, the root water absorption intensity is higher. Under warming treatment, the root water absorption intensity first increases and then decreases with soil depth, with the highest root water absorption intensity in the 5–20 cm soil layer. (3) Transpiration amplification: For different climate change scenarios, for every 1 ℃ increase in soil surface temperature, the transpiration of the alpine meadow on the QTP will increase by about 21.2∼22.43 %. During the growing season of the alpine meadow, the transpiration increase in August is as high as 24.62∼25.87 %.
