Abstract: Methane emission from paddy cultivation is one of the major anthropogenic activities releasing methane into the atmosphere. Various parameters like water management, cultivars, nature of fertilizer, soil temperature and texture have been investigated and found to change the emission by a few times to orders of magnitude . Studies of irrigation practices in India have shown that submergence is not necessary for high yields and controlled irrigation can be very effective in mitigation of methane emission without affecting the yield. The use of cultivars having high yields associated with low methane emission and use of appropriate fertilizer can reduce methane emission by more than an order of magnitude. Measurements carried out in the National Physical Laboratory, New Delhi have also shown an excellent correlation of methane emission with soil temperature and suggest the increase in paddy cultivation in the Rabi season to be another important measure to mitigate methane emission. Possibilities of implementing the aforesaid mitigation measures to reduce methane emission are discussed along with the options available through the Clean Development Mechanism in the agriculture sector and their importance for India. Comparative cost estimates of methane mitigation measures for rice cultivation and the least cost mitigation option that might be used for the country are also discussed in this paper.
