Abstract:

In recent years, the persistent issue of climate change, attributed to global warming induced by the accumulation of greenhouse gases, has become increasingly significant. In the global effort to address climate change, governments focus on the formulation and implementation of policies designed to manage and diminish the surge in greenhouse gas emissions responsible for the phenomenon of global warming. For this reason, it is becoming increasingly important to analyze the determination of greenhouse gas emissions released by agricultural production. This study aimed to determine the carbon dioxide emissions from cultivating some oil field crops in the Eastern Mediterranean Region. Oilseed sunflower, soybean, and peanut were selected from the oilseed crops widely cultivated in the region. In the five years between 2018 and 2022, the total production area of the three crops was 152 974 ha, the total production amount was 557 868 tons, and the total yield was 3.65 tons ha-1. With the fuel-based CO2 emission calculation method proposed by the Intergovernmental Panel on Climate Change, the average CO2 emission, specific fuel consumption, and specific CO2 emission resulting from the cultivation of sunflower, soybean, and peanut crops in 2018-2022 were determined as 58.45 ktCO2, 81.08 gfuel kgproduct-1 and 275.84 gCO2 kgproduct-1, respectively. In soybean and peanut production, fuel consumption and CO2 emissions were highest in tillage and lowest in spraying. In sunflower production, the highest fuel consumption and CO2 emissions occurred in the transportation process and the lowest in the fertilization process.
