Growing crop production increases agricultural water consumption (AWC), but whether these two factors are matched in northern and southern China in the past two decades remains controversial. Here we used a remote sensing‐based water‐carbon coupling model combined with satellite observations to quantify the crop production, AWC, and water deficit changes in China over 2003–2018. We show that in northern China, crop production and AWC significantly (p < 0.05) increased, mainly due to planting area expansion, and the increasing rates were 2.6 and 6.2 times greater than those in southern China. The increasing irrigation demand in northern China greatly reduced the availability of stored terrestrial water and could not be met by the agricultural water supply in the next two decades. Our results show that the conflict between the limited agricultural water supply and the increasing irrigation demand cannot be resolved by the South‐to‐North Water Diversion Project, and better management in water resources and crop production is needed to achieve the United Nations Sustainable Development Goals.

“…A high water table, over-irrigation, rainfall after irrigation, and inadequate drainage increase flooding stress [5]. The inappropriate engineering of the drainage system hinders water removal from the field, whereas a shallow water table also intensifies the waterlogging conditions Figure 1 [40]. An upward-sloping topography in the land also enhances the flooding situation, where an inefficient irrigation system prevails in low-lying soil positions [5,41].…”

Climate-change-induced variations in temperature and rainfall patterns are a serious threat across the globe. Flooding is the foremost challenge to agricultural productivity, and it is believed to become more intense under a changing climate. Flooding is a serious form of stress that significantly reduces crop yields, and future climatic anomalies are predicted to make the problem even worse in many areas of the world. To cope with the prevailing flooding stress, plants have developed different morphological and anatomical adaptations in their roots, aerenchyma cells, and leaves. Therefore, researchers are paying more attention to identifying developed and adopted molecular-based plant mechanisms with the objective of obtaining flooding-resistant cultivars. In this review, we discuss the various physiological, anatomical, and morphological adaptations (aerenchyma cells, ROL barriers (redial O2 loss), and adventitious roots) and the phytohormonal regulation in plants under flooding stress. This review comprises ongoing innovations and strategies to mitigate flooding stress, and it also provides new insights into how this knowledge can be used to improve productivity in the scenario of a rapidly changing climate and increasing flood intensity.

To facilitate agricultural water rights trading reform in China and improve the efficiency of agricultural irrigation, an effective and practical approach called the conversion coefficient from electricity consumption to irrigation water supply (CCECIWS) method is introduced in this study. Application of this method in Siyang County is meticulously investigated. First, four measurement strategies are employed for the precise estimation of the volume of irrigation water from agricultural irrigation water pumps (AIWPs) in Siyang County. Then, the CCECIWS data collected through on‐site testing and the distribution pattern of the CCECIWSs of AIWPs are analysed, and the ranges of the CCECIWS values for different groups are delineated. Conjoint analysis is conducted to quantify the influence of two factors on the CCECIWSs. Finally, three regression models are developed and validated to predict the CCECIWSs for the remaining 60% of the total AIWPs, which are not tested on site. The prediction results show that the regression models have acceptable accuracy. The contribution of this research is the provision of a practical and efficient CCECIWS method to indirectly evaluate the irrigation water supply, saving both time and economic costs and laying the foundation for future research on this topic.
