Singapore lab makes strides in identifying optimal rice growing conditions with reduced methane

Temasek Life Sciences Laboratory (TLL) is leading a project to decarbonise rice farming by reducing methane emissions, which account for 1.5% of global greenhouse gases. By testing variables like rice variety, soil additives, and irrigation methods since 2022, researchers aim to cut emissions by at least 20% and improve rice yields by 5% through more climate-resilient practices.

Methane levels are measured in a lab setup at the National University of Singapore (NUS), mimicking rice field conditions. The project has already shown early success in lowering emissions and boosting yields.

The next phase will take the research to real-world rice fields in India, Indonesia, and Laos, working with local farmers across 100 hectares in each country to enhance soil health and drought resistance.
