Methane budget from paddy fields in India

Results of national methane campaign launched in 1991 to assess methane budget from Indian paddy fields are reported. The campaign involved a number of scientific institutions and universities with National Physical Laboratory at Delhi operating as a nodal agency and covered most of the major rice growing regions of India. Methane emission rates ranged between −0.64 and 84.1 mg−2h−1. The methane budget from Indian paddies has been estimated to be around 4.0 TgY−1 with a range between 2.7 to 5.4 TgY−1.
