Methane (CH4) is one of the most abundant organic gases in the atmosphere. Recently the importance of CH4 as a greenhouse gas has been recognized and studies have been carried out to asses its contribution to global warming. In this paper we show that atmospheric CH4 is produced by a wide variety of natural and anthropogenic processes. Then, we discuss mainly production, consumption and emission of CH4 in paddy fields. Finally, we provide an estimate of the mitigation potential in agricultural systems including rice production, ruminant animals and animal waste.
