Paddy rice production causes significant methane emissions in comparison to other cropping systems.

The Alliance’s Paddy Rice Research Group is working together to find ways to reduce the emissions intensity of paddy rice cultivation systems, while improving its overall production efficiency. Trade-offs with emissions of nitrous oxide and changes of the quantity of carbon stored in paddy soils are also being considered.

The Group’s activities are completed by two sub-Groups that focus on regional rice production systems:

  • Latin American sub-Group including CIAT as partner
  • Asia sub-Group

Summaries of previous meetings

The Group has met six times. Summaries of the most recent meetings are provided below.

The Group’s work is focused on improving countries’ national inventories of greenhouse gas emissions from paddy rice cultivation systems.

It will also help provide knowledge of source/sink extents and mitigation options to paddy rice farmers, land managers and policy makers by looking at the impacts of water management, organic matter and fertilisers and cultivar selection.

The Paddy Rice Group has a particular focus on identifying good practice and gaps in current knowledge, standardising measurement techniques, and developing improved country-specific emission factors and mitigation options. Relevant literature is being compiled in a database. Over time, the Group will look at how to scale up results across countries and extrapolate solutions to the long term. A future goal is the development of an experimental protocol for a multi-site, multi-country field experiment.

Group collaborations

A key aim of the Paddy Rice Group is to increase country participation and partnerships with relevant non-government research organisations and initiatives.

The Group currently works with the following networks and organisations:

Monsoon Asia Agro-Environmental Research Consortium (MARCO)
International Rice Research Institute (IRRI)
International Centre for Tropical Research (CIAT)
The Cooperative Program for the Technological Development of Agriculture and Agribusiness for the Southern Cone (PROCISUR)
