The Evaluation of Greenhouse Gas Emissions from Pineapple Cultivation in Pran Buri District, Prachuap Khiri Khan Province, Thailand: Implications for Sustainable Development Goals (SDGs)

Objective: This study evaluates greenhouse gas (GHG) emissions from pineapple cultivation in Pran Buri District, Prachuap Khiri Khan Province, with reference to the United Nations Sustainable Development Goals (SDGs), particularly SDG 12 and SDG 13. Theoretical Framework: The research applies a life cycle perspective to identify emission sources across different stages of pineapple cultivation, aligning with sustainability and climate action frameworks. Method: A random sample of 10 pineapple farmers was surveyed. Data on raw material sourcing, soil preparation, transplanting, irrigation, fertilizer use, harvesting, transportation, consumption, and waste disposal were collected. Emissions were quantified in kgCO₂eq/rai and analyzed statistically to assess variation across farmers and cultivation activities Results and Discussion: The study found that soil preparation, fertilizer application, irrigation, and waste disposal were major contributors to GHG emissions. The average emission was 743.089 kgCO₂eq/rai. While no significant differences were found among farmers (p = 0.353), significant differences were observed across activities (p = 0.0009). The 2–8-month care period was the most emission-intensive due to fertilizer, chemical inputs, and higher irrigation demand. Research Implications: Findings highlight the importance of adopting sustainable agricultural practices to mitigate emissions and strengthen Thailand’s agricultural contribution to the SDGs. Originality/Value: This study provides one of the first localized assessments of pineapple-related GHG emissions in Thailand, offering empirical evidence to guide sustainable cultivation strategies.
