Abstract
<p class="abstrak2">South Korea has declared to reduce greenhouse gas emissions by 30% compared to the current level by the year 2020. The greenhouse gas emissions from the cattle production sector in South Korea were evaluated in this study. The greenhouse gas emissions of dairy cattle, Non-Korean native cattle, and Korean native (Hanwoo) cattle production activities in 16 local administrative provinces of South Korea over a ten-year period (2005–2014) were estimated using the methodology specified by the Guidelines for National Greenhouse Gas Inventory of the IPCC (2006). The emissions studied herein included methane from enteric fermentation, methane from manure management, nitrous oxide from manure management and carbon dioxide from direct on-farm energy use. Over the last ten years, Hanwoo cattle production activities were the primary contributor of CH<sub>4</sub> from enteric fermentation, CH<sub>4</sub> from manure management, NO<sub>2</sub> from manure management and CO<sub>2</sub> from on-farm energy use in the cattle livestock sector of South Korea, which comprised to 83.52% of total emissions from cattle production sector.</p>
Highlights
Greenhouse gas (GHG) emissions from human activities become a focus of worldwide attention because of global warming issues
This study focused on three primary emission sources in cattle production activities: Emissions from enteric fermentation, emissions from manure management, and emissions from direct on-farm energy use
Lee & Lee (2003) reported that methane emission from the enteric fermentation of Hanwoo cattle was 1.54 Mt in 2001, whereas we found that methane emissions were 4.21 Mt CO2-eq in 2014 from the enteric fermentation of Hanwoo
Summary
Greenhouse gas (GHG) emissions from human activities become a focus of worldwide attention because of global warming issues. The agricultural sector contributes 18% (7.1 billion tonnes CO2 equivalent) to the total global greenhouse gas emissions (FAO 2006). Agricultural activity contributes only 9% to global CO2 emissions, agriculture generates 65% of human-related nitrous oxide (N2O) and 35% of methane (CH4) with global warming potentials (GWPs) of 298-fold and 25-. Livestock production is a critical contributor in agricultural activity that produces greenhouse gases and contributes approximately 42% to the total GHG emissions, with 28% of the emissions directly from enteric fermentation and 14% from indirect emissions due to the handling, storage, and land application of manure (AAFCCT 2000)
