However, the potential of irrigation modernization in achieving water savings on the basin level is contentious. Whether it also improves the Nile basin system efficiency is studied in this paper by simulating Egypt's Nile River water balance using the River Basin Simulation Model (RIBASIM-Delwaq) under regular, high, and low inflow conditions. In addition, the impacts of three irrigation modernization strategies (all canals lined, drip irrigation on all agricultural land, all canals lined and drip irrigation on all agricultural land) were investigated for the system efficiency, water reuse, and outflow to the Mediterranean. The results show that the Nile Basin system efficiency in Egypt is very high under the baseline conditions reaching up to 75.6 % due to formal and informal water reuse activities. This leaves little room for modern irrigation strategies to achieve higher system efficiencies; 75.6 %, 78.5 %, and 77.0 %, respectively. The paper concludes that modern irrigation will not increase system efficiency or the outflow to the Mediterranean significantly, however, it will reduce official and unofficial water reuse by allowing farmers to receive more water from canals instead of drains and shallow groundwater.</div></div>","PeriodicalId":7634,"journal":{"name":"Agricultural Water Management","volume":"316 ","pages":"Article 109576"},"PeriodicalIF":5.9,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144169351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigated field drainage discharge and pesticide losses in a rice growing area between 2018 and 2020 in the lower Yangtze River plain, Eastern China. As the local pest control protocol adopts a pre-irrigation practice to pond the application fields for enhanced killing effect, we examined the potential pesticide losses with field drainage under the increased hydraulic gradient. Based on the observed drainage flow and concentrations of a popular pesticide -chlorpyrifos (CPF), we analyzed the concentration distribution in the paddy environment, especially in field drainage ditches (FDs), and subsequently developed an event-based analytical model to calculate concentration changes along the drainage pathway. The monitoring results in 2018 and 2019 showed that CPF concentration spikes appeared in a FD under low flow condition, the observed higher concentrations as compared to paddy field water and groundwater indicate direct deposits from spray drifts or over-application in the FD. A large storm after pesticide application in 2020 caused high flow event, but no apparent concentration spikes were observed in the FD. Of the 3 monitoring events, the pesticide chemographs did not synchronize with the flow hydrographs, the average pesticide losses were as low as 0.16–0.2 % of the applied amounts. Prediction with the event-based analytical model showed that pesticide concentrations may be lowered by 2–3 orders from the FD to downstream waters for the low flow and high concentration events. Further analysis for onsite mitigation of pesticides showed that, controlled drainage can be adopted to reduce pesticides in the field ditches through the dilution and degradation effects.

This study proposed a dynamic rainfall storage control strategy based on 1–7-day weather forecasts. To evaluate its effectiveness, the AquaCrop model was modified by incorporating a waterlogging stress coefficient, resulting in the ACOP-FRice model. The model accurately simulated rice yield under various waterlogging conditions and demonstrated strong stability across growth stages. During the validation period, the late tillering stage showed the best performance of yield simulation accuracy, with a normalized root mean square error (NRMSE) of 7.39 %, and both the coefficient of determination (R²) and nash-sutcliffe efficiency (NSE) coefficient values reaching 0.83. Although the heading–flowering stage was the most sensitive to flooding, the model still achieved reasonable accuracy, with an NRMSE of 11.61 % and R² and NSE values of 0.81, indicating its ability to capture yield variations under complex stress conditions.

Compared with the wet year, drought stress triggered a 53.3 % yield loss for sesame in dry year.

Previous studies have focused primarily on analyzing the thermal evolution and response mechanisms of soil temperature with respect to various meteorological factors, neglecting its response across different timescales for dry/wet conditions. This research examines response patterns from four perspectives: trends, seasonal sensitivity, propagation, and response relationships. Based on these patterns, the random forest model was employed to simulate the cumulative soil temperature (CST) during dry and wet periods, using the duration and severity of these periods at different soil depths as input variables. Using long-term monthly observations (1966–2022) from the Wudaogou National Comprehensive Hydrological Observation Station in Anhui Province, China, we analyzed the soil temperature at depths of 0–320 cm paired with meteorological data. The standardized precipitation evapotranspiration index (SPEI) was employed to characterize dryness/wetness across various timescales (from 1-month to 12-months). The results indicate the following: (1) A distinct shift in soil thermal dynamics was observed, with a cooling trend prior to 1992 transitioning into a pronounced warming phase thereafter. The post-1992 warming rate was 3–4 times faster than the overall rate for 1966–2022, revealing critical temporal shifts in soil temperature responses. (2) Shallower soil layers (0–40 cm) exhibited heightened seasonal sensitivity to dryness/wetness, responding more rapidly and intensely than deeper layers (&gt;80 cm), especially at short timescales (≤3 months). This underscores the critical role of surface soil interactions in thermal dynamics. (3) A ‘compression’ phenomenon in temperature transmission was identified, where the influence of dryness and wetness on soil temperature diminishes with increasing depth. Dry periods consistently elevated soil temperatures, whereas wet periods reduced them, providing insights into vertical thermal propagation mechanisms. (4) The random forest model showcased a strong capability to simulate CST achieving <em>R</em>² and <em>Ens</em> values above 0.91 and absolute <em>PBIAS</em> values below 5 %.

This crop-specific approach enhances our analysis of compound events' impacts on agricultural commodities. We examine both the compound and individual AgHWS conditions, tracking their changes through time. This is achieved through the implementation of historical reconstruction (back to 1961) and future projections (to 2099) using suitable CMIP5 models for Australia. For this, we utilise daily temperature and soil moisture data from the Australian Bureau of Meteorology's high-resolution (0.05°) National Hydrological Projections using CMIP5 climate forcing together with the Australian Water Resources Assessment – Landscape (AWRA-L) model. These projections are examined under two Representative Concentration Pathways (RCP4.5 and RCP8.5) and are compared to historical outputs from the AWRA-L model. Results indicate that: (1) AgHWS conditions are projected to increase in frequency, and intensity in future years with earlier onsets and prolonged durations across Australia; (2) AgHWS duration will rise from approximately 10 days per event in the late historical period to around 30 days per event for RCP 4.5, and 50 days per event for RCP 8.5 in the late future; (3) Northern Australia is projected to be severely impacted by AgHWS conditions while agricultural regions in south-eastern and south-western Australia appear to be less so; and (4) Water stress contributes most to the creation of AgHWS conditions, underscoring the importance of soil water conservation management.
