,Carbon Sequestration and Greenhouse Gas Fluxes from Cropland Soils – Climate Opportunities and Thregetation and twice the amount in the atmosphere (IPCC 2001). The annual uxes of carbon dioxide (CO.) from atmosphere to land (global Net Primary Productivity ) and land to atmosphere (respiration and re) are of the order of 60 Pg Cyr.

Environmental Parameters Influencing the Methane Emissions in the Pantanal Floodplain, Brazil,dicals, and the stratosphere, because of its participation in the chlorine and water vapor chemistry. Methane is also an important greenhouse gas, with a relative contribution of about 20% for the global greenhouse effect (Wuebbles and Hayhoe 2002). Many works have evidenced that an increase of the

Possibility of Water Management for Mitigating Total Emission of Greenhouse Gases from Irrigated Pain many countries throughout the world, but 88.4% of rice area is concentrated in Asia and its production reaches 90.4% of the total of the world (Table 14.1). The current rice production is more than twice of that in the 1960s, and will further increase to feed the growing human population, especia

Mitigating Greenhouse Gas Emission from Agriculture,gases, mainly carbon dioxide (CO.), methane (CH.) and nitrous oxide (N.O) – collectively known as greenhouse gases (GHG). Concentrations of CO., CH. and N.O have increased markedly as a result of human activities since 1750 and now far exceeded pre-industrial values as determined from ice cores span
