Rice cultivation causes the emission of CH4 consequenced to the global warming. Reduction of irrigation in rice cultivation is not only saving water resources but also reducing greenhouse gases emission. The objectives of this study was to determine impacts of water management on the emission of CH4 and rice yield. Experiment was conducted in field conditions in An Giang province, Viet Nam with three treatments as continuous flooding (CF), An Giang Alternative Wetting and Drying (AAWD) which is mostly applied by farmers in An Giang province-Viet Nam, and Alternate Wetting and Drying (AWD). Water levels in the field +5 cm, ± 5 cm and -15 cm were controlled higher, fluctuated and lower than soil surface, respectively for CF, AAWD and AWD. CH4 emission determined every week during 13 weeks of the experiment. Rice yield was determined in 1 m2 at the end of the experiment. The results showed that AWD and AAWD, respectively decreased 78.7 % (p < 0.05) and 6.8 % (p > 0.05) CH4 emission compared to the CF 11.9 mg CH4/m2/h. The rice yield of CF was 6.32 ton/ha lower than AAWD 7.8 ton/ha (p < 0.05) but not different with AWD 6.67 ton/ha. AAWD had higher rice yield but same emission than the CF. Farmers in An Giang province should consider application of AWD in rice cultivation in term of saving water and reduction of CH4 emission.

Abstract Background Irrigation systems have been identified as one of the factors promoting malaria disease around agricultural farms in sub-Saharan Africa. However, if improved water management strategy is adopted during rice cultivation, it may help to reduce malaria cases among human population living around rice fields. This study aimed to assess the impact of the different irrigation practices on malaria transmission, as well as to evaluate the water management system that will best mitigate malaria transmission in Malanville, Benin. Methods Knowledge, Attitude and Practice (KAP) study was conducted on 104 households staying on and around the rice fields in Malanville. The study focused on the frequency of mosquito bites and preventive measures against malaria as well as soil preparation and rice planting methods. Mosquito larvae density was assessed in different water management system: continuous flooding (CF) or intermittent flooding (IF), deep tillage (DT) or minimal tillage (MT) and normal levelling (NL) or abnormal levelling (AL) in an experimental hut set-up. Larvae were collected using dipping methods and their density was determined. Results Three tillage systems, which include the use of tiller, plow and hoe, were identified on the rice field. Continuous flooding was the only irrigation system used by farmers. Retrospective data from Malanville Health Centre revealed higher malaria cases during rice production season, which was also confirmed by field participants. The density of Anopheles larvae was reduced by 80.8%, 30.8% and 40.7% (P = 0.000) during transplanting, tillering and maturation periods, respectively with intermittent flooding compared to continuous flooding. In addition, a clear reduction of larva density was observed with both intermittent flooding systems applied to minimal tillage (MT + IF + NL) and intermittent flooding applied to deep tillage (DT + IF + AL), showing that intermittent flooding could reduce the abundance of malaria vector in rice fields. Conclusion Recommending intermittent flooding technology for rice cultivation may not only be useful for water management but could also be an intentional strategy to control mosquitoes vector-borne diseases around rice farms.

According to long-term studies of the influence of rice cultivation show that meadow-black soil, meadow, alluvial, meadow-swamp (heavy black soils) soils of the reclamation and water management complex of the Lower Kuban, with the beginning of their use for rice cultivation, lose their favorable physical properties and become degraded, merged, viscous and gleyed formations, which leads to a decrease in the yield and quality of the resulting grain, loss of soil fertility, as a rule, with the subsequent withdrawal of lands from the irrigation fund. In order to prevent these negative consequences, it is necessary to use the accumulated world experience of rice cultivation in a timely manner. For a number of reasons, many scientific achievements in the field of selective breeding and rice production technologies remain unpopular. Today, the level of information technology allows studying the advanced experience of rice cultivation in a short time. The world leader in rice production is the PRC, where for more than 10 years they have been practicing the cultivation of rice using drip watering under mulching film, considering this method to be one of the most effective and resource-saving. However, the rice-growing regions of the PRC are located in subtropical and tropical climates with the sum of active temperatures and solar activity during the growing season significantly exceeding the average values of these values for the rice-growing regions of the reclamation and water management complex of the Lower Kuban. Consequently, to implement this technology on the rice irrigation systems of the Krasnodar Territory, it is necessary to adapt them to the natural and climatic conditions of the region. Therefore, the paper proposes the technology of underground drip watering of rice, the introduction of which has proven its effectiveness and feasibility.
