IRRI and BASF launch Phase 2 of rice GHG reduction research

The International Rice Research Institute and BASF launched Phase 2 of Optima research on October 1, 2026, a collaboration aimed at reducing greenhouse gas (GHG) emissions from rice fields. Phase 1 demonstrated that combining direct-seeded rice, better fertilizer management, and alternate wetting and drying (AWD) can reduce methane emissions and water use without lowering yield. Phase 2 will investigate how soil organic carbon changes based on planting frequency, rice straw management, and the addition of organic materials.

The research utilizes IRRI’s Otyza computer model to track water movement and predict methane release, which is useful for counting GHG reductions and supporting future carbon farming programs. The work addresses how specific agricultural practices impact soil fertility and environmental output.
