Greenhouse Gases Emissions from Rice Production – Methane
• Produced by bacteria in anaerobic soils
• Stimulated by Continuous Flooding:~ 2.5–5 t CO2eq seas-1
~ 1-2 kg CO2eq kgrice
• Emission highly dependent on water management and organic amendment (e.g. manure, straw)

Alternate Wetting and Drying
Flooded field is left to dry out
When water level drops to a threshold (15cm below soil surface), the field is
irrigated again
Perforated tube for
observing water level in
the soil
AWD saves up to 30% of irrigation water and reduces GHG
emissions by ~50%

Trees in Rice Landscapes
• In 2010, 43% of all agricultural land globally had at least 10% tree cover
• Tree cover in agricultural land increased by 3.7% from 2000-2010- Indonesia among the countries with largest increase - Myanmar among the countries with largest decrease

Thai Rice NAMA Project (2018 – 2022)
• Partners:* Thai Rice Department* GIZ/ BRIA (Better
Rice Initiative for Asia)* IRRI* Bank for Agriculture `
and Agricultural Co-operatives (BAAC)
• Promoting AWD in combination with LLL aiming at 100,000 farmers to reduce emissions by 1.7 Mt CO2eq
• Project receives 15 Mio EUR from NAMA Facility and is expected to generate at least equal amount from Thai Government and private sector
