In my quest for more reliable figures for the greenhouse gas contribution of rice, I contacted several experts. I have received answers back from two of them. Dr. Reiner Wassman, scientist at the International Rice Research Institute, writes:
“The proximate amount can be derived based on the IPCC guidelines (http://www.ipcc-nggip.iges.or.jp/public/2006gl/vol4.html):
Emission of methane: 130 kg CH4/ [...]

New figures on rice and climate change
SRI methods double rice yield
A farmer in Lombok, Indonesia, holds two rice plants of same variety. The plant on the left was grown with SRI methods and the one on the right with conventional methods.
SRI not only greatly increases yield, it uses less water and emits vastly less CO2 than rice grown in the traditional way by being flooded.
Growing more rice with less water
Rice is an essential food for literally billions of people. But it requires enormous amounts of water and emits huge amounts of methane while growing, due to being underwater.
However, a new system of growing rice, the SRI method, increases yields, uses much less water, and emits no methane.
If the SRI method was applied to 20 [...]
