Mitigation options to reduce methane emissions in paddy rice

The Paddy Rice Component of the Climate and Clean Air Coalition's (CCAC) Agriculture Initiative aims to implement the alternate wetting and drying (AWD) technology, on large scale, in Vietnam, Bangladesh, and Colombia to significantly reduce methane emissions from rice fields. With support from CCAFS, IRRI coordinates the activities of this component in Vietnam and Bangladesh, while CIAT covers the work in Colombia.

The program will address major constraints to mitigation in paddy rice by identifying (1) best management practices that achieve both mitigation and food security and (2) incentives, technical support mechanisms, and enabling conditions to overcome the barriers that men and women farmers face in using new practices. Based on these assessments, the Paddy Rice Component will produce technical and policy guidance for national governments to implement greenhouse gas (GHG) mitigation options at large scales.

Phase 1 of the component will produce

Theory of change

Project activities will work with countries to improve and implement AWD+ at large scales. Activities will fill key gaps in knowledge and practice related to:

By sharing knowledge and testing practices with agricultural development stakeholders in these four areas, this research will catalyze investments and actions at the country and multi-lateral levels.  


The CCAC Paddy Rice Component is jointly undertaken by IRRI and CIAT and works very closely with national stakeholders in target countries. These include policymakers, farmer associations, irrigation infrastructure managers, and farm input providers among others. Our contact institutions for in-country activities are the Institute for Agricultural Environment (IAE) in Vietnam, Bangladesh Agricultural University (BAU) in Bangladesh and the national federation of rice farmers (Fedearroz) in Colombia. The low-emissions agriculture flagship of CCAFS supports the component financially and provides assistance.
