“…The result shows YR water can be saved with maximum benefit at the upper bound. This is similar to the finding of Zhang and Qtaishat, reallocating water from irrigation to other higher-value uses such as industry or service industry can obtain its potential economic value [45,49]. It is quite meaningful to evaluate the irrigation water saving potential under the maximum benefits.…”

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.

“…According to Qtaishat (2013), large-scale irrigation systems carried out by (central) governments are very effective, so that allocation of public water resources can support food security. However, large-scale irrigation systems cannot guarantee an equitable water distribution and sustainable O&M without irrigation institutions with a good capability.…”

One aspect that plays an important role in the performance of irrigation systems is the institutional division of irrigation areas' authority covering the authority of district/municipality, provincial and the central government. This study aimed to assess how the institutional division of irrigation areas' authority affect the performance of irrigation systems, to reclassifies the standard of performance index of irrigation systems, to analyze the status of irrigation system performance in 6 districts/municipalities in the semi arid region of Timor Island, East Nusa Tenggara based on their authority and mapping of spatial diversity. This study used descriptive statistical method through the performance index of irrigation systems in 6 districts/ municipalities. This study concluded that the status of the irrigation system performanceof 6 districts/municipalities in the semi arid region of Timor Island increased along with the level of irrigation systems' authority. The best Status of the performance of irrigation systems in 6 districts/municipalities was Malaka District Irrigation System, the performance tended to be better in the irrigation system under the authority of central government that administratively placed in one district/municipality (non cross district irrigation system). Based on the analysis of the status of irrigation system performance in 6 districts/municipalitiesin Timor Island, a specific step for each district/municipality to adjust the location characteristics with policies can be taken to overcome irrigation systems' problems in the semi arid regions of Timor Island.

“…Specifically, from 2000 to 2016, agricultural water consumption accounted for 32.9% of the total water consumption in Beijing Municipality, 53.1% of the total water consumption in Tianjin Municipality, and over 70% of the total water consumption in Hebei Province. Water resources move from the agricultural sector to the industrial sector [33,34], which puts enormous pressure on food security. Therefore, for the Jing-Jin-Ji region, it is necessary to study effective irrigation for food security.…”

Maize is a major crop that is particularly sensitive to climate change. In addition, the extreme shortage of water resources threatens crop production. Thus, improving the effective utilization rate of water is an important problem to discuss. In this regard, we quantified the combined effects of meteorological conditions and irrigation levels during different growth stages on city-level maize yields in the Jing-Jin-Ji region from 1993 to 2019. The results show that the sowing period was affected by the minimum temperature, while the other growth stages were affected by the maximum temperature. At the ear stage of summer maize, when the effective irrigation rate reached the average level (52%), the inflection point of the total precipitation was 401.42 mm in the Jing-Jin-Ji region. When the total precipitation was higher than 401.42 mm, the summer maize yield decreased with the increasing total precipitation. Furthermore, the summer maize growth was significantly affected by drought at the seedling stage. At high effective irrigation rates and over long dry spells, as the mean daily temperature during dry spells increased, the maize yield easily increased. The increase in the effective irrigation rate can reverse the decrease in the summer maize yield. Moreover, the effective irrigation rate increased the maize yield with the increase rise in the temperature during longer dry spells, but the maize yield decreased with warmer temperatures during shorter dry spells. As such, our evaluation results will be useful for assessing food security and moving gradually toward achieving a water–energy–food nexus.
