“…However, rainwater harvesting, storage, and use for AWD were signifi cantly lower than CID due to the lower-fi eld water depth [26]. Similar observations were made in the present study, and CID treatment improved the effective irrigation volumes and reduced irrigation frequencies over AWD, which means that effi cient use of rainwater is improved and drainage pressure of paddy fi elds is reduced.…”

Paddy is the most important grain crop in China. In addition, water is one of the most important components for sustainable paddy production, and the quantity of irrigation for paddy fi elds accounts for approximately 70% of its total agricultural water resource consumption [1]. However, water supply is limited because of serious regional and seasonal water shortages, and paddy production is impaired by increasing water shortage [2]. Meanwhile, China is the largest producer and consumer of synthetic fertilizers in the world. Fertilizer and pesticide overuse in order to achieve high paddy yields might result not only in poor grain yield but also low N use Pol. J. Environ. Stud. Vol. 27, No. 1 (2018), 345-355 AbstractAlternate drought and fl ooding stress has become more prevalent during paddy growth stages as a result of climate change, especially in southern China. This study aims to assess the effect of alternate drought and fl ooding stress on water use, and nitrogen (N) and phosphorus (P) losses in paddy fi elds. Two controlled irrigation and drainage (CID) managements (namely drought at the beginning of growth stages followed by fl ooding (CID-1), and fl ooding at the beginning of growth stages followed by drought (CID-2) and one alternated wetting and drying (AWD) management were designed in specially designed experimental tanks with three replications in 2015 and 2016. Results showed that CID increased effective irrigation quantities and rainwater storage ability with a signifi cant decrease in water use effi ciency compared with AWD. For surface water, CID-1 signifi cantly improved possible losses of nitrogen and phosphorus during the fertilizer application period over CID-2. For subsurface water, CID can signifi cantly reduce the leaching losses of nitrate N and P compared with AWD. Meanwhile, CID-1 signifi cantly inc reased the leaching losses of nitrate N at the former two growth stages compared to CID-2, yet no signifi cant difference was found for ammonia N and P. Therefore, the application of controlled irrigation and drainage -especially for CID-1 -was an effi cient method for obtaining high water quality and reducing eutrophication.

“…However, if the rice crop undergoes a severe AWD (soils are dried significantly) the loss in the final yield was over 20% compared to the continuous flooding method [51]. Similarly, a study reported that alternate wetting and drying irrigation showed a higher paddy yield (8516-8346 kg ha −1 ) in two years of experimentation as compared to controlled irrigation treatments (6532-7868 kg ha −1 ) [52].…”

By the end of this century, the average global temperature is predicted to rise due to the increasing release of greenhouse gases (GHGs) into the atmosphere. This change in climate can reduce agricultural yields, resulting in food insecurity. However, agricultural activities are one of the major contributors of GHGs and lower yields can trigger increased activity to meet the demand for food, resulting in higher quantities of GHGs released into the atmosphere. In this paper, we discuss the growth requirements and greenhouse gas release potential of staple cereal crops and assess the impact of climate change on their yields. Potential solutions for minimizing the influence of climate change on crop productivity are discussed. These include breeding to obtain cereals that are more tolerant to conditions caused by climate change, increased production of these new cultivars, improved irrigation, and more effective use of fertilizers. Furthermore, different predictive models inferred that climate change would reduce production of major cereal crops, except for millets due to their ability to grow in variable climatic conditions, and in dry areas due to a strong root system. Moreover, millets are not resource-intensive crops and release fewer greenhouse gases compared to other cereals. Therefore, in addition to addressing food security, millets have an enormous potential use for reducing the impact of agriculture on global warming and should be grown on a global scale as an alternative to major cereals and grains.

“…The effects of stress associated with the production of the materials dry low during periods of flood and stress during the period of withdrawal the following stress. About the efficiency of irrigation water use, it increases under two, and by the first treatment of at least 101% to a maximum of 110% [7]. The growth of the plant with the use of the old seeds with the addition of organic fertilizer and inorganic gives a high production.…”
