This study aimed to analyze the holistic amount of greenhouse gas emission of Napier Pakchong 1 grass plantation in Prachinburi Province, Thailand, in a term of carbon footprint. The carbon footprint of Napier plantation from irrigation plot and non-irrigation plot was 17.182 and 19.138 kg CO2e/ton of Napier Pakchong 1 grass, respectively. The largest contribution to the greenhouse gas emission came from the fertilizer application. The irrigation to the crop significantly increased the crop yield resulting in the reduction of greenhouse gas emission per unit weight of the crop. The suitable type and the optimal quantity of fertilizer application, as well as the most efficient irrigation system with the least environmental impact, were suggested for further study.

This study aimed to estimate the carbon footprint and analyze the environmental hotspots of the cultivated banana cultivation in a case study of Prachinburi Province in Thailand. In addition, the study proposed the mitigation of the carbon footprint. Primary data were obtained from eleven Prachinburi banana farmers. The banana farmers were interviewed using a questionnaire. Planting area, plant spacing, yield, land preparation, planting, fertilization, irrigation, and harvesting were among the data collected. The results revealed that the carbon footprint of cultivated banana cultivation was 117 g CO2e/kg of fresh cultivated banana, with fertilization accounting for 83 percent of the total. To predominantly reduce greenhouse gas emissions, the usage of fertilizer should be reduced. Different parts of the plants, such as trimmed leaves, de-suckered shoots, and stems should be chopped into small pieces and spread over the soil where the bananas are planted to nourish the plants without supplemental fertilizer. However, the reduced usage of fertilizer for banana cultivation should be studied along with the productivity of the crop.
