Global Warming, Emission Of Methane Gas And Rice Production
MetadataShow full item record
Global warming nowadays has became the world attention. Glass house gas such as CO2, N2O, and CH4 can cause the global warming. Emission of CO2, N2O, and CH4 contribute about 55, 15 and 6 percent of total glass house effects. Atmospheric methane (CH4) as glass house is more effective than CO2. The global warming stimulated by increasing of glass house glass emission continuously as side effect of human being activities (anthropogenic) and it is yielded also by burning the forest, agricultureal and live stock activities. In the agricultural sector, the efforts to increase the rice production and its quality have conducted. The problem of global warming must be one of the factors in watching the agricultural problems. Global warming will influence on crop production and water availability. Some innovations of paddy culture have done. Therefore, cultural techniques for food crops that consider the environment are necessary. The research at China has shown that paddy culture will decrease about 5-12% if the temperature increases about 3.6oC. The same case also happens at Bangladesh. Rice production in the country will decrease about 10 percent. The relation of global warming an agricultural sector, especially on paddy production has been the attention of stakeholders. The global warming conference that done at Bangkok, Thailand months ago reminded to study the system of rice culture to eliminate the glass house effect that becomes the cause of global warming. There is no culture of crop that supports the biggest of methane emission except paddy. The emission of methane gas at paddy is unique. Paddy produces the methane gas that produced from the organic manure decomposition, and also produces the carbon dioxide that yielded from burning of paddy waste. The effort of paddy culture also produces the nitrogen dioxide from decomposition of fertilizer. All of the gasses are the cause of green house effects.
