“…According to the experts interviewed in this study, it can be argued that the feasibility of practicing rain-fed agriculture under the current status of water shortage in Mashhad could be considered as one of the most significant strengths of using rain-fed agriculture in the city. The studies conducted by Rockstrom [34], Swatuk [35], and Dunkelman [36] highlight the feasibility of rain-fed agriculture in conditions of water scarcity, as opposed to irrigated agriculture. These findings support the results of the present study.…”

The practice of rain-fed agriculture plays a vital role in both the economy and food security, yet it is subject to various challenges such as climate change and institutional barriers. This study employs the Strengths, Weaknesses, Opportunities, and Threats (SWOT) analyses, Best-Worst Method (BWM), and Weighted Aggregated Sum Product Assessment (WASPAS) integrated approach to identify the most effective strategies for improving and developing sustainable rain-fed agriculture in Mashhad, Iran. The SWOT analysis identifies the essential sub-factors for improving and developing sustainable rain-fed agriculture. Then, the BWM method is utilized to assign weights to each sub-factor. Finally, the WASPAS method is used to rank the 19 strategies that can help achieve sustainable rain-fed agriculture. The findings of this study reveal that the strategy of establishing an institutional framework to promote sustainable rain-fed agriculture (WT7) has received the highest score. On the other hand, strategies related to supporting policies at the farm level (ST2, WO3, WT2, WT1) were placed in the middle and final priorities. Thus, it is recommended that in the current context of rain-fed agriculture in Mashhad, policymakers prioritize institutional policies related to rain-fed agriculture over farm-level policies. This study proposes a comprehensive and systematic approach to enhance and promote sustainable rain-fed agriculture.

“…The theoretical detachment from the earlier state-centred hydro hegemony scholarship is only apparent; water embedded in food and, thus, traded among states is still considered transboundary and follows patterns expressed through the classic hydro hegemony (and co-existing conflict and cooperation) analysis. When global food trade is considered, no water basin can be considered to be closed in the sense that there is not enough water in the system (see Swatuk et al 2015). All basins are now open and connected to every other water basin on earth through virtual water rivers (Greco 2013).…”

“…Water resources are crucial for the production and preservation of human beings, and the shortage of water resources throughout the world is becoming increasingly severe [1,2]. The arid and semi-arid region in Northwest China has low rainfall and large evaporation capacity, so water resources, particularly agricultural water, are scarce in this region [3,4].…”

Film hole irrigation is a relatively low cost and high efficiency irrigation method, which can significantly improve the efficiency of agricultural water use. In order to establish the quantitative model of film hole irrigation between cumulative infiltration and the wetting body and the irrigation volume model of crops, the infiltration process and wetting body characteristics of four different soils (Xi’an silt loam, silt, silt loam and loam) were studied in laboratory experiments and numerical HYDRUS simulation experiments. The relationship between cumulative infiltration and wetting body radius was established using a mathematical method, and a crop irrigation volume model was proposed based on the root distribution and the required water content of different crops. The experimental results showed that the shape of the wetting body of film hole irrigation is approximately half of the rotating ellipsoid, and the curve shape of the wetting front can be expressed using an elliptic equation. From the center of the film hole to the surface of the wetting front, the soil water content of the wetting body gradually decreases, and the change rate of water content gradually increases, reaching its maximum value near the wetting front. Furthermore, the distribution of water content in the wetting body can be accurately expressed using an elliptic curve equation. The cumulative infiltration of film hole irrigation is proportional to the third power of the equivalent radius of the wetting body, and the equivalent radius is equal to the geometric mean of the horizontal and vertical migration distances of the wetting front. In addition, based on the distribution of crop roots and the demand of crop roots on soil water content, the irrigation model of crops was established. This study provides a theoretical basis for the calculation of the irrigation volume for film hole irrigation under the condition of experiment, and has a guiding significance for the field experiment and application of film hole irrigation in different crops in future.
