This study presents an updated estimation of annual Greenhouse Gas (GHG) emission from crop and rice cultivations from year 2008 to 2012 in Sarawak. This includes GHG estimation from rice cultivations, biomass and soils organic. The estimation of GHG emission in this study is conducted in accordance to 2006 IPCC guidelines for Agriculture, Forestry and Other Land Use (AFOLU) sector, where uncertainty analyses are incorporated. This study also presents findings at urban and non-urban areas of Sarawak and its comparisons. It is found that, the change in biomass for both urban and non-urban areas in Sarawak increases yearly with significant changes in biomass at urban areas at 160.29×103 tons C yr-1 as compared to non-urban areas at 45.90×103 tons C yr-1. It is also found that, the annual carbon loss from cultivated organic soil at urban areas is higher at 6.17×106 tons C yr-1 in Miri. Total CH4 emission from wet paddy in non-urban areas is found to be higher than urban areas at 19.01 Gg CH4 yr-1. This study would unable relevant authorities to use the values of GHG emission estimated in this study for the purpose of analysis on vulnerability, adaption and mitigation. © The Authors, published by EDP Sciences, 2017.
