“…It should be noted that the increased irrigation efficiency in S2 and S3 scenarios will lead to reduced leaching in the root zone [53]. The leaching is vital in areas with higher salinity water sources for maintaining soil health and increased crop production [53,54]. As the leaching factor is highly site specific and irrigation water quality dependent, it is an issue requiring further investigation.…”

Due to poor water resources management, groundwater-dependent agriculture induces substantial stress on several aquifer systems worldwide, which poses a serious threat to water and food security. However, only a few studies have addressed this vital issue. This study aimed to evaluate stress on aquifers due to the overuse of groundwater for food production and explore pathways for stress reduction via improved irrigation efficiency and productivity. Groundwater stress was characterized using the ratio of water use to availability, with consideration for environmental flows. The results indicated that out of 107 countries—dependent on groundwater irrigation, about half are overexploiting groundwater, while one-fifth of these countries are extracting moderately-to heavily. Over 90% of the non-renewable groundwater abstraction occurs in 7 countries. Further, about 450 million tonnes (Mt) of global annual food production is from non-renewable groundwater exploitation. If the existing irrigation efficiency is increased to 90%, current groundwater stress would be reduced by 40%. Additionally, in unstressed regions, it would be possible to produce additional 300 Mt of food by using saved water while maintaining groundwater stress at acceptable levels. Moreover, improved water productivity in conjunction with increased irrigation efficiency could reduce the current level of unsustainable food production by 47%. These results provide important insights into the dynamics of irrigation stress on groundwater systems, and the role of managerial interventions.

“…These great challenges facing both governments and academia all over the world are securing safe and fresh water supply, global food security or sustainable food production, and fossil energy exhaustion or energy conservation (Liu et al 2022). Thus, several studies reported about irrigation strategies in the recent decades that reduce water applications through "Deficit Irrigation strategies or DI" and allowing the irrigation efficiency use itself to be increased without any impacts on plant growth or harvested yield (Slamini et al 2022). Partial Root-zone Drying (PRD) is a new form of DI, an effective irrigation method, and can improve yield per unit of water applied compared to traditional irrigation by saving amount of water (Slamini et al 2022).…”

ATER is the main limiting factor of our life and any human activity. In all our life activities including agriculture and industry, water has a vital role in these previous sectors. This reflects the importance of water especially under many global challenges (mainly climate changes, global explosion of population, soil degradation, desertification and hunger). The using of water in irrigation is a very common practice in agriculture because no agriculture without water. The management of irrigation water has become one of the urgent needs nowadays under the terrible progress of bioinformatic technology. The smart irrigation is considered one of the most common applications in smart or precision agriculture. The main components of smart irrigation system may include soil, weather and plant sensors such as soil moisture sensor controllers, evapotranspiration controllers, and rain sensors. This work is an attempt to answer one question about smart irrigation whether it is an important strategy to overcome the global water crisis or not. This is also a call by Environment, Biodiversity and Soil Security (EBSS) for receiving articles on smart irrigation, different applications of smart irrigation in smart agriculture, their challenges, their obstacles and the novel solutions in this concern. This topic has several open questions needs to be answered. The use of the Internet of Things is one of the important solutions for smart monitoring and control of the irrigation process.
