Assessment of the Greenhouse Gas Emissions Palm Oil Plantation: A Case Study of Oil Palm Farmers, Sikao District, Trang Province
Main Article Content
Abstract
This study aimed to evaluate the greenhouse gas emissions from the production of palm oil in Sikao District, Trang Province by Life cycle assessment of the product from tillage, cultivation, maintenance, harvesting, and transportation. This study collected data by the palm oil plantation from nine farmers having palm oil more than 50 rai and nine farmers having palm oil less-thanor equal to 50 rai. Agriculture has palm oil in three different ages that are 0-4 years, 5-12 years, and 13 years or more, 3 samples per age group. The results from this study show that the greenhouse gas emissions (GHG) of a tillage process from farmers who possess palm oil areas more than 50 rai is equal to 0.63 kgCO2eq per rai more than the GHG emissionfrom farmers who possess palm oil areas less-than or equalto50 rai is 0.61 kgCO2eq per rai. For a cultivation process, the GHG emission from farmers who possess palm oil less-than or equal to 50 rai is equal to 257 kgCO2eq per rai which is more than those produced from farmers who possess palm oil area more than 50 rai that is 191 kgCO2eq. In the maintenance process of palm oil, the GHG emission from farmers who possess palm oil areas more than 50 rai is equal to 243.09 kgCO2eq more than the GHG emission from farmers who possess palm oil area less-than or equal to 50 rai is 103.04 kgCO2eq per rai. During the process of harvesting and transporting to the buyer, the GHG emission from farmers who own palm oil plantation of less than or equal to 50 rai are equal to 17,309 kgCO2eq per rai, more than the GHG emission from farmers who own palm oil plantation of more than 50 rai is equal to 5,383 kgCO2eq per rai.
