ú for rainfed rice we used the figure of 1.17 for Southeast Asia, which is the weighted average of<br />
data for Thailand (1.09) and the Philippines (1.73); the same value was used for all other regions.<br />
ú for deep water rice we used the same factors as for irrigated rice.<br />
In this way we included in the methane emissions trend for 1970-1990 the influence of the changing<br />
mix of cultivation types as well as of the of rice varieties used and the declining amounts of organic<br />
inputs in rice cultivation. The resulting trend of this methodology is shown in Fig. 4.5.<br />
