Abstract—Open burning of rice straw causes release of air
pollutants, which contributes to enhance climate change related
issues. Moreover, the burning practice was a reason of losing
carbon content from crop land to the atmosphere. This study
focuses on estimation of carbon content loss to the atmosphere
through open burning of rice straw and suggests alternative rice
straw management practices to reduce field open burning in
Thailand. Field experiments were conducted to collect samples
of rice straw to quantify residue to product ratio (RPR) and
analyze their carbon content by elemental analysis. Ash samples
were also collected to analyze their carbon content. Carbon
losses to the atmosphere through field burning were then
estimated. To better understand traditional practices of open
burning in Thailand, statistics related to seasonal rice
production/harvesting were also investigated. Finally, economic
and environmental benefits associated to alternative rice straw
management options were considered and discussed against
traditional open burning practices.
Index Terms—Rice straw, residue to product ratio, field open burning, carbon released
