Kahlil and Rasmussen (1990) reviewed eleven global methane budgets published between 1978 and 1988. They found methane emissions from rice paddies ranged from 18 to 280 Tg/year which correspond to between 10 and 70% of the total anthropogenic methane emissions. For the paper, the authors have reviewed and replicated three published techniques to estimate methane emissions from rice paddies. The authors present the results obtained and propose to include soil characteristics to revise these estimates. Since 90% of rice production occurs in Asia, the authors have focused the study on rice in Asia.
