“…LIS development is further hampered by the absence of strong stakeholder networks at the local level (Córcoles et al ., 2010) and competent public services, which would offer support to the stakeholders (Elshaikh, Jiao, & Yang, 2018; Cvejić et al ., 2019; Fadul et al ., 2020). An approach to LIS implementation is required that would encourage, rather than inhibit, the bottom‐up initiatives.…”

Large‐scale irrigation systems (LIS) are massively utilized in agriculture worldwide to ensure food security and mitigate the effect of global warming. LIS face unpredictable changes in climate, technologies, and societal tendencies during their lifetime, potentially becoming unusable or insufficient. In this case study of Slovenia, the evolution of LIS was divided into five characteristic periods in terms of motivation, mechanisms, and the key stakeholders. The heyday of LIS development in the late 1980s was followed by denationalization and privatization, and construction was replaced by measures for improving the status irrigation at the state level. Simultaneously, there was a shift in global development towards modernization as LIS should be adaptive to changes throughout their existence in order to preserve their functionality. The construction of LIS resumed less intensively in the European Union during 2007–2013, with recognition of effective LIS functioning as necessity. This study confirms that irrigation development follows the global imperative focus on more effective use of the existing LIS along with simultaneous reduction in the environmental impact of agricultural production through smarter use of water, nutrients, and plant protection products. This should be achieved by organized LIS users, increased knowledge, efficient LIS maintenance and management, and improved connections to the local markets.

“…The calibration of the infiltration equations by WinSRFR and SIRMOD was done by the trial-and-error 14 , 64 . To calibrate the continuous irrigation in SIRMOD, the initially field-measured values of the non-conservative parameters a , k , and f 0 were fine-tuned and calibrated.…”

The SIRMOD and WinSRFR models were used to model and assess the irrigation performance under continuous and surge irrigation strategies with two furrow lengths of 70 m and 90 m and stream sizes of 0.4 l/s and 0.6 l/s for each length. According to the normalized root mean squared error (NRMSE) and the relative error (RE), WinSRFR had, on average, excellent accuracy in the continuous and surge irrigation for simulating advance-recession times (NRMSE: 6.15 and 4.24% for advance time, and 2.20 and 5.20% for recession time), infiltrated water depth (NRMSE: 3.37 and 6.38%), and runoff volume (RE: 6.93 and 2.57%), respectively. SIRMOD had also, on average, excellent simulation in the continuous and surge irrigation for advance-recession times (NRMSE: 3.34 and 2.45% for advance time, and 2.28 and 6.41% for recession time), infiltrated water depth (NRMSE: 2.98 and 5.27%), and runoff volume (RE: 5.31 and 17.49%), respectively. The average of irrigation application efficiency (AE), distribution uniformity (DU), deep percolation (DP), and tail-water ratio (TWR) were 61.50, 90.25, 11.75, and 26.75% in continuous irrigation, and 72.03, 94.09, 8.39, and 19.57% in surge irrigation, respectively, which shows that surge irrigation increased AE (irrigation management performance) and DU (irrigation method performance) and reduced DP and TWR compared to continuous irrigation. Moreover, longer furrow lengths increased AE and DP under both irrigation methods, while it decreased TWR and DU. However, increasing the stream size decreased AE and DP and increased TWR under both continuous and surge irrigations. The higher stream size improved DU in continuous irrigation but reduced DU in surge irrigation. The results confirmed that both SIRMOD and WinSRFR are reliable analytical tools to evaluate furrow irrigation strategies for improving irrigation management. In conclusion, this study showed that surface irrigation models could be employed in practice by irrigation engineers and practitioners to design and define the optimized furrow length and stream size in arid and semi-arid areas where efficient and high performance irrigation strategies are required to save water and reduce water loss.

“…Data from the International Commission on Irrigation and Drainage, published on the Food and Agriculture Organization's Aquastat website, show that surface irrigation is used on 97% of the irrigated area in India, 94% in China, 44% in the United States, and 100% in Pakistan (i.e., the 58% of the world's total irrigated area). In general, among the different types of surface irrigation, border irrigation is the most common method for watering row crops worldwide (Fadul et al 2020), especially in Australia (Kohec and Langat 2018), northern China (Liu et al 2020), and southern Europe (Masseroni et al 2017).…”

The effects of climate change on water availability affect the performance of surface irrigation, which is the oldest and most common method of water application to row crops worldwide. A paradigm shift towards strategies aimed at increasing flexibility of irrigation scheduling and improving the design and management of field layouts and irrigation practices should be explored to promote water savings at the farm scale. In this study, we investigate how adopting a more flexible irrigation scheduling and optimizing irrigation management variables and field layout it is possible to increase the efficiency of border irrigation and thus achieve water savings and improve quality of crop production. The analysis of the actual performance of border irrigation was carried out on two maize fields located in the Padana Plain (Northern Italy) in two years characterized by different rainfall patterns (i.e. 2021 and 2022). Based on this information, continuous monitoring of soil moisture status combined with the AquaCrop-OS agro-hydrological model was used to manage flexible irrigation scheduling over the experimental fields. While the optimization of irrigation management (flowrate per unit width and cutoff time) and field geometries (border width and slope) was studied using WinSRFR 5.1 USDA software, which was properly calibrated by measures of waterfront advance and recession. The results show that with flexible irrigation scheduling and proper irrigation management and field layout, significant water savings can be achieved. Specifically, in the case study, seasonal water savings of about 10% were obtained just by scheduling irrigation based on actual crop water needs in a very dry agricultural season, while water savings reached up to 60% in a wetter season. On average, an additional 7% of water savings was achieved over the agricultural season when the irrigation duration was correctly applied to each border of the experimental plots, while approximately 20% of water was saved when the border width was correctly designed based on inflow availability. These results provide useful information for improving the management of border irrigation in practice, both under current conditions and in the face of increasing freshwater scarcity in the future.
