Methane (CH4) is one of the main greenhouse gases produced by the agricultural sector. Rice cultivation activities are the second largest contributor to methane emissions after livestock from the agricultural sector. Most of the land use in Kapanewon Tempel is used for rice fields. 31,7% of the total area of Tempel District in 2021 is rice fields. The aim of this research is to determine the extent and distribution of rice fields in Kapanewon Tempel, as well as the potential and distribution of methane gas emissions produced. The aim of this research is to determine the extent and distribution of rice fields in Tempel District, as well as the potential and distribution of methane gas emissions produced.
The method used in the research is a method developed by the Intergovernmental Panel on Climate Change-IPCC (2006) and the IPCC refinement (2019). Mapping of rice fields in the research was carried out using Landsat 8 OLI imagery with the help of Google Earth imagery. The images used were taken during the rainy and dry seasons in 2015 and 2022. The research data used came from interviews with sources and literature studies.
The research results show that the area of wet rice fields in Kapanewon Sleman amounted to 600 hectares in 2015 and increased by 418 hectares in 2022. The El Nino phenomenon in 2015 caused a drought so that the utilization of wet rice fields in Kapanewon Tempel became low, while the La Nina phenomenon in 2022 has an opposite impact, although the resulting impact is not as big as the El Nino event in 2015. The potential value of methane gas emissions in Kapanewon Tempel in 2015 was 2300,76 kg CO2 equivalent per year and increased to 4080,47 kg CO2 equivalent per year in 2022. The area of wet rice fields is directly proportional to the amount of methane gas emissions produced. The increase in the area of wet rice fields in Kapanewon Tempel causes an increase in the potential for methane gas emissions in the area. The subdistrict with the highest area of rice fields in Kapanewon Tempel in 2015 was Banyurejo Subdistrict and in 2022 it was Tambakrejo Subdistrict.
