GREEN-HOUSE GAS EMISSION AND CONTROL IN RICE FIELD: AN AGRICULTURAL NOTETarika Sharma
Upland agricultural system primarily emits N2O, however, flooded Rice systems emits both CH4 and N2O. Climate change concerns have led to efforts to reduce greenhouse gas emissions from agricultural systems. Agriculture accounts for approximately 10-12% of total global anthropogenic emissions of greenhouse gases, which amounts to 60% and 50% global nitrous oxide and methane emission respectively. Carbon dioxide is another greenhouse gas, however, on a global scale; soil CO2 fluxes are largely offset by net primary productivity and atmospheric CO2 fixation by crop plants and thus contributes less than 1% to the global warming potential of agriculture.
