Global warming and rice based cropping system

Abstract

International Pannel for Climate Change approximates that the global temperature would rise between 1.50 and 4.50 Celsius by some time in twenty-first century. Since the advent of the industrial revolution in the 1700s, human beings have devised many inventions that burn fossil fuels. Burning these fossil fuels as well as other activities such as clearing land for agriculture or urban settlements, releases some of the gases that trap heat in the atmosphere leading to global warming. Carbon dioxide, methane Nitrous oxide chloro-fluoro-carbons comprises the green house gases. Soil in the earth surface is viewed both as source and sink for most of the green house gases. Agricultural practices such as rice cultivation and clearing of the biomass results in the emission of green house gases. It is always not too late for good beginning, so knowledge and research is emphasized for understanding the green house gases emission and its reduction from agricultural practices.
