Special Issue Information

Dear Colleagues,

Irrigated cropping covers 346 million ha, representing 20% of global agricultural land, contributing 40% of the world’s food production. In 2010, globally, 1500 km3 of water was used for irrigation but 2700 km3 was withdrawn for this purpose, resulting in an irrigation efficiency (IE) of only 56%. Currently, 70% of the global freshwater supply is diverted for irrigation, with little opportunity for sourcing additional water in the future. Therefore, it is imperative that water use efficiency (WUE) of irrigated cropping be improved to meet the projected doubling of food production by 2050, required to feed an estimated nine billion people.

Growing competition and increasing scarcity for fresh water pose challenges to agricultural industries to improve WUE and reduce the environmental footprints of irrigation. Moreover, with climate change predictions, with increases in temperatures and frequent episodes of weather anomalies, irrigation is crucial for adapting agriculture to a changing climate. In response to these challenges, wide range of research efforts have been carried on various aspects of crop WUE. A Special Issue of Water, “Advances in Agriculture Water Efficiency” aims to bring scattered research from different disciplines into a single volume so that a holistic understanding and application of WUE research is made available to a diverse audience.  

Improving WUE requires an interdisciplinary approach, involving irrigation and drainage engineering, agronomy, breeding, soil science, crop nutrition and a wide range of applied irrigation sciences plus environmental, socio-economic, geopolitical and cultural aspects relevant to irrigation. We solicit papers from different disciplines that contribute to the enhancement of crop WUE at different scales of plant production (leaf to landscape level), required to make meaningful gains in improving water productivity at a global scale. We believe the inclusion of such a wide range of interdisciplinary research and review papers will be instrumental in guiding the future for meaningful improvements in agricultural WUE globally. We encourage your contributions and looking forward to your submissions.

At present, the shortage of water resources has become a serious constraint to the further development of social economy. The optimal allocation of multi-water resources is valuable for agricultural water management in arid and semi-arid regions. However, traditional deterministic programming does not solve the complex water resources allocation in irrigation systems. Furthermore, previous allocation methods of irrigation water seldom considered the water cycle process, especially for multi-sources of irrigation. In this study, we develop an inexact fuzzy stochastic simulation-optimization programming (IFSSOP) model for the irrigation water optimal allocation of two water sources. The model combines the crop water model and the field water cycle model with an uncertainty optimization model, which considers the contribution of groundwater to crop water consumption. As a case study, the developed model is used in an arid area with two irrigation water sources: a river and a lake. Accordingly, the total optimal allocation irrigation water amounts of river and lake water under different violation probabilities in various hydrological years were obtained. By comparing the IFSSOP model with the IFSSOP model without considering the contribution of shallow groundwater (IFSSOP-NG model), it can be shown that the system benefits of the developed model are higher. With the lake water source from flood water, the region can save 30–34% of the river water, maintaining the original crop water deficit irrigation ratio. Consequently, application of the IFSSOP model in irrigation scheduling will provide effective water allocation patterns to save more water in an arid region with shallow groundwater. Full article
