WAVE BCG and PTT Energy Launch "Sustainable Rice, Reduce Methane with Alternating Wet and Dry Rice" Project

Strategic Insights

— 2 min read

WAVE BCG Co., Ltd. has joined forces with PTT Energy Public Company Limited to launch a project aimed at reducing greenhouse gas emissions in the agricultural sector. The project, titled "Sustainable Rice, Reduce Methane with Alternating Wet and Dry Rice," targets 500 rai of rice fields in Suphan Buri Province and will practice low-carbon agriculture. The company plans to develop new-age agricultural innovations, including "Alternate Wetting and Drying" (AWD), to promote changes in rice cultivation methods for Thai farmers. The project aims to reduce methane emissions, a potent greenhouse gas, and support organizations in achieving their goals of reducing greenhouse gas emissions to combat global warming.

Key Takeaways:

  • WAVE BCG and PTT Energy launched the "Sustainable Rice, Reduce Methane with Alternating Wet and Dry Rice" project, targeting 500 rai of rice fields in Suphan Buri Province.
  • The project aims to develop new-age agricultural innovations, including "Alternate Wetting and Drying" (AWD), to promote changes in rice cultivation methods for Thai farmers.
  • The project is expected to reduce methane emissions, a potent greenhouse gas, and support organizations in achieving their goals of reducing greenhouse gas emissions to combat global warming.
  • The agricultural sector is the second-largest source of greenhouse gas emissions, with half coming from rice areas in Thailand.
  • The project plans to train farmers on the wet-dry rotation rice (AWD) method and introduce the use of an application for tracking results and monitoring the planting season.
  • The project will be monitored for three years, and carbon credits will be certified in the third year.
  • The project follows the Thailand Standard (T-VER) high standard for voluntary greenhouse gas reduction projects.
  • The cultivation of rice in a wet-dry rotation allows the soil to dry out at intervals, reducing the anaerobic decomposition process and methane emissions.
  • The trend of buying and selling carbon credits from the agricultural sector, especially alternating wet and dry rice farming, has become popular abroad and is expanding in Thailand.
  • Thailand has the potential to expand its area of wet and dry rice farming, with 10.6 million rai of potential for alternating wet and dry rice farming.

Statistics:

  • 500 rai of rice fields will be targeted in Suphan Buri Province
  • 3,300 rai of rice fields will be changed to new-age agricultural innovations, including AWD
  • 0.3-0.4 tons of carbon dioxide equivalent will be reduced per rai of rice field using AWD
  • 10.6 million rai of potential for alternating wet and dry rice farming in Thailand
  • 61.9 million rai of rice growing area in Thailand in 2023
  • 62% of Thailand's rice growing area is in the Northeastern region
  • 16.4% of Thailand's rice growing area is in the Northern region
  • 12.6% of Thailand's rice growing area is in the Central region
  • 9% of Thailand's rice growing area is in the Southern region
