  • This study estimates Korea's livestock energy consumption and GHG emissions from Korean livestock sector. The results show that livestock energy consumption in 2013 is 474 thousand TOE, 19.0% of total energy consumption in agriculture sector. It is estimated that GHG emission of fuel combustion from livestock sector is 956 thousand tons of $CO_2$ equivalent while a total of 4,589 thousand tons of $CO_2$ equivalent is emitted from agriculture sector. The livestock GHG emission as a proportion of the total agriculture GHG emissions (20.8%) is higher than the livestock energy consumption as a proportion of agriculture energy consumption (19.0%). This is because coal and petroleum consumption in livestock sector as a proportion of the total livestock energy consumption is higher than that in agriculture sector.

  • The objective of this study was to review application of next-generation sequencing (NGS) to investigate microbiome in the livestock sector. Since the 16S rRNA gene is used as a phylogenetic marker, unculturable members of microbiome in nature or managed environments have been investigated using the NGS technique based on 16S rRNA genes. However, few NGS studies have been conducted to investigate microbiome in the livestock sector. The 16S rRNA gene sequences obtained from NGS are classified to microbial taxa against the 16S rRNA gene reference database such as RDP, Greengenes and Silva databases. The sequences also are clustered into species-level OTUs at 97% sequence similarity. Microbiome similarity among treatment groups is visualized using principal coordinates analysis, while microbiome shared among treatment groups is visualized using a venn diagram. The use of the NGS technique will contribute to elucidating roles of microbiome in the livestock sector.

  • In recent years, there has been a growing argument attributing the primary cause of global climate change to livestock industry, which has led to the perception that the livestock industry is synonymous with greenhouse gas (GHG) emissions. However, a closer examination of the global GHG emission by sector reveals that the energy sector is responsible for the majority, accounting for 76.2% of the total, while agriculture contributes 11.9%. According to data from the Food and Agriculture Organization of the United Nations (FAO), the total GHG emissions associate with the livestock supply chain amount to 14.5%. Within this, emissions from direct sources, such as enteric fermentation and livestock manure treatment, which are not part of the front and rear industries, represent only 7%. Although it is true that the increase in meat consumption driven by global population growth and rising incomes, has contributed to higher methane (CH4) emissions resulting from enteric fermentation in ruminant animals, categorizing the livestock industry as the primary source of GHG emissions oversimplifies a complex issue and disregards objective data. Therefore, it may be a misleading to solely focus on the livestock sector without addressing the significant emissions from the energy sector, which is the largest contributor to GHG emissions. The top priority should be the objective and accurate measurement of GHG emissions, followed by the development and implementation of suitable reduction policies for each industrial sector with significant GHG emissions contributions.

  • The purpose of this paper is to come up with the measures for sustainable development of the agricultural sector in store for the strengthened U.N. Framework Convention on Climate Change. We analyze the spillover effects of Methane and Nitrous Oxides taxes (carbon tax) on the Korean agricultural sector. Unlike the other sectors, the agricultural sector has a unique characteristic generating greenhouse gas in the process of production itself even without consuming much fossil fuel. In order to estimate the impacts of those taxes, non-linear optimization method has been used with various assumed scenarios. The production effect, income and' price effect, and greenhouse gas emission reduction effect in the agricultural sector have been estimated through this method. The empirical results show that the paddy sector has a bigger tax effect than the livestock sector. In the paddy sector, the carbon tax has more impacts in the suburban areas than in the rural areas, while the swine farming section in the livestock sector has a conspicuous income effect in the midst of low greenhouse gas emission effect. These results allude us to apply graded tax rates to the crop, the livestock, and the region of different kind. Even if the agricultural sector has a less tax effect when compared with other industrial sectors, an environmental tax might be an effective measure to prevent global warming.

  • In this study, researches on the development of country specific greenhouse gas measurement and sampling methods from the livestock sector were reviewed. Research on greenhouse gas emission factors was started in early 2000 but was not actively involved in the development of livestock sector based emission factor: since 2009, works are underway for the development of livestock sector based emission factor. Most of the research on greenhouse gas emission in the field of animal studies were done by National Institute of Animal Science, because of the uniqueness of the research laboratories. Methods of emission measurement are still not internationally certified and therefore, measurement and sampling methods for Korea livestock sector are being studied, consulting the worldwide research trends. Flux chamber method are commonly using in Korea for green house gas emission factors measurement. In recent years, continuous measurement of the microclimate was introduced to measure greenhouse gases from livestock manure storage facilities and the micrometeorology method should be adapted as recommended by Intergovernmental Penal on Climate Change (IPCC) Guideline.

  • The equations and emission factors for estimating national GHGs are developed based on IPCC guidelines. The GHGs on livestock sector has been calculated using methodologies following 1996 IPCC guideline in South Korea although 2006 IPCC guideline was announced in 2006. The purpose of this study is to understand the implications of guideline updates for national GHGs changes in the livestock sector and analyze the effect of regional major livestock characteristics using KOSTAT time series data (1990 ~ 2014). The results show a new guideline makes GHGs reduce in the livestock sector up to 11 % with subdivided emission factors and the livestock characteristics affect regional GHGs. Gyeonggi-do, the top emitter among 16 states, records 784 thousand tons $CO_2eq.$ and Daejeon has the highest potential (82 %) of GHGs reduction. Swine is the most contributor for regional GHGs except Seoul and Gwangju, but the share of GHGs for chickens is less than 12 % in spite of the largest livestock population (87 %).

  • IT 기술의 발달과 함께 각 분야에서는 IT와 융합한 기술을 개발하고 있으며, 축산분야에서도 구제역발생 이후에 IT를 활용한 가축의 관리에 관심을 가지고 있다. 최근에는 정보통신 기술이 유비쿼터스 기술로 진보하면서 U-축산의 도입이 필요한 시점이다. U-축산의 도입을 위해서는 우선 현재 업무에 대한 분석을 통하여 서비스 모델 도출이 필요하다. 본 연구에서는 축산 부문의 서비스모델을 가축 생애주기별로 구분하여 기존의 국내외 사례들을 기반으로 하여 도출하였다. 이중에는 현재 사업으로 진행되고 있는 것도 있으며, 앞으로 진행되어야 할 것들도 있다. 향후에는 도출된 서비스 모델에 대하여 각 서비스모델별로 목표를 설정하고, 기능을 정의하며, 플랫폼을 정의하는 과정이 필요하며, 단일 서비스모델이 아닌 통합된 서비스모델로서 방향을 진행하여야 할 것이다. 이제 축산업에서도 유비쿼터스기술을 활용한 U-축산 도입을 통하여 첨단화 되고, 효율적인 방식으로 가축관리가 진행되며, 산업 경쟁력 및 생산성을 높일 수 있을 것으로 기대된다.

  • 축산농가로부터 발생되는 악취문제는 지역사회에 중요한 이슈로 떠오르고 있다. 본 연구는 미국의 콜로라도 주의 한 지역(Weld County)에서 거래된 3,355개의 주택이 199개의 축산농가의 악취 때문에 거래가격에 얼마나 영향을 받았는지를 분석하였다. 특히 주택시장에 잠재적으로 존재하는 공간상관관계를 분석에 포함하기 위해 공간 헤도닉 모형을 이용하였다. 결과를 보면 이 지역은 전통적으로 육우와 비육우 농가가 많아서인지 소규모의 육우와 비육우 농장은 오히려 농촌의 전형적인 전원생활의 일부로 주택가격에 양의 파급효과로 나타났다. 그러나 악취로 인한 주택가격의 영향은 축산업의 규모와 업종에 따라 차이를 보였다. 일정규모 이상을 넘어서는 농가와 특정 업종은 주택가격을 하락시키는 것으로 분석되었다. 특히 대규모의 양돈과 양(sheep)은 주택과 근거리에 있는 경우 지역사회에 결정적인 경제적 손실을 초래하고 있음을 알 수 있었다. 축산업의 악취는 부정적인 외부효과의 하나로 지역사회에 사회적인 비용으로 나타난다. 정책결정자는 이 같은 사회적인 비용을 최소화하고 지역경제개발 효과를 극대화하기 위해 이 같은 사회적인 비용을 지역계획 수립에 반영해야 한다. 특히 주택과 축산업의 위치와 특성을 적절히 고려해야 할 것이다.

  • This paper aims to provide a basic framework to make a regional plan for the environment-friendly agriculture. To prepare the regional plan is mandated by the Environment-friendly Agriculture Promotion Act of 1998. Here is proposed the input/output analysis framework, which includes the shifts of fertilizers, herbicides, pesticides, and livestock manures Basically, the discharged amount of polluted elements means the difference between the amount of the elements entered into the crop and livestock sectors and the amount of the elements absorbed or used by the crop and/or livestock. A few suggestions are offered for better regional environment-friendly agricultural plan. The foremost important thing is to establish a data collection system. The \"Green Accounting System\" is suggested. It is also crucial to create a standard guideline or manual which Provides detailed procedures to follow in making the plan by the local planners. More fundamentally, many experts on the regional planning will be demanded in the near future. Some compound model which links, for instance, the forestry, the livestock sector, and the crop sector, needs to be devised. Finally, it is argued here that more elaborated model will work as an integrated environmental improvement plan which embraces living environment as well as agricultural environment.vironment.
