CCAC 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 project aims to develop an innovative approach based on highlighting co-benefits of mitigation options, integrating alternate wetting and drying (AWD) into a farming strategy, as opposed to approaches focusing on emissions reductions only.
ICON explores and quantifies the ecological consequences of future changes in rice production. The goal is to provide understanding in balancing the revenues and environmental impacts of high yielding rice cropping systems.
The project seeks to develop an improved water management, based on alternate wetting and drying (AWD), that can always reduce soil-derived CO2-eq emissions (CH4 + N2O) during the rice growing season from irrigated rice paddies, by 30% compared to the conventional practice.
In an effort to develop innovative agronomic solutions to anticipated needs for production of more rice on less land with more efficient use of labor, water, and other inputs, IRRI established the Ecological Intensification (EI) platform in 2011.
