  • 전 세계적으로 지구온난화의 원인인 대기 중 온실가스 농도를 감축하는 여러 정책들이 모든 산업을 망라하여 추진되고 있다. 식량안보라는 특수성은 있지만, 농업도 예외는 아니다. 이런 취지에서 최근에 농산물의 전체 생산과정에서 발생하는 탄소배출량을 산정하고, 이를 토대로 탄소배출량이 적은 농산물 생산방식을 도입하고자 하는 요구가 증가하고 있다. LCA 도구를 농업분야의 환경평가에 적용한 해외 연구 사례들을 살펴보면, 스위스는 Ecoinvent가 주축이 되어 농작물, 농업기반시설, 농자재, 농기계 등 농축산 전반에 대한 LCI D/B를 구축하여 제공하고 있고, 우리와 농업시스템이 유사한 일본은 산업연관분석을 이용하여 농업을 위한 Top-down 방식의 LCA 수행 방법론을 개발하였으며, 이를 농작물 생산 방식에 따라 평가하고 농업분야에 대한 영향평가 방법론과 가중치를 개발하였다. 반면에 국내의 LCA를 통한 농업환경영향평가는 출발 단계에 있다. 따라서 농업환경에 있어 주요 인자인 비료 및 농약에 대한 환경영향을 평가하고 이를 위한 국내 비료와 농약의 흐름 모델링, 방법론 개발이 요구되며, 국내 농업 시스템을 반영한 기타 농자재, 농기계 및 농업기반시설에 대한 환경영향평가 역시 수행되어야 한다.

  • This study analyzes the impacts of agricultural water shortages in Korea using a combined top-down and bottom-up model. A multi-region multi-output agricultural sector model with detailed descriptions of production technologies and water and land resource constraints has been combined with a standard CGE model. The impacts of four different water shortage scenarios were simulated. It is shown that an active adaptation of crop choices occurs in even the regions with relatively abundant water resources in order to respond to the change in relative output prices caused by water shortages. We found that although the losses in production values are not quite large despite water shortages due to the price feedbacks, the loss in GDP is substantial. We show that our combined approach has advantages in deriving region and product specific production effects as well as the overall GDP loss effect of water shortages.

  • As the importance of renewable energy diffusion spreads, promotion of sustainable renewable energy projects such as agrivoltaics is expected to accelerate. Furthermore, to promote agrivoltaics projects, it must be considered the legislation related to agrivoltaics and Chungnam Province's local policy. This research focuses on the selection of the most suitable sites for agrivoltaics installations in Chungnam Province in South Korea. Therefore, the process of this research was as follows. First, the legislation related to agrivoltaics and local policy in Chungnam Province were identified. Second, it employs an analytic hierarchy process (AHP) to consider important criteria and their weights for site selection. Third, based on the weights calculated AHP, geographic information system (GIS) was performed to select most suitable location selection of agrivoltaics installations in Chungnam Province. The analysis identified approximately 60 promising most suitable location for agrivoltaics installations in Chungnam Province, primarily in the northern part of Chungnam Province. These areas are expected to meet electricity demands in nearby regions since these are relatively adjacent to Gyeonggi Province. According to the results of research, policy suggestions related to agrivoltaics were presented separately into the agricultural sector and the electricity power sector. The study's results serve as a valuable resource for future national-level candidate site selection for agrivoltaics projects.

  • The objectives of this study were to estimate the potential biomass yield by using the biomass conversion index and evaluate the potential energy production by using the energy conversion index of biomass. Estimating the total biomass yield in Korea showed 9,646.3 thousand tons produced in 2012. Subsequent evaluation of the potential energy production using the estimated biomass yield in 2012 indicated that the calorific values were varied from 3,800 to 4,500 kcal $kg^{-1}$ for crop- and from 4,100 to 4,300 kcal $kg^{-1}$ for woody-based biomass, respectively. Among the examined biomass materials, the pruned branch of a nut tree appeared to be the greatest in bio-energy production showing 6,300 kcal $kg^{-1}$ in calorific value. Total potential energy production from agricultural by-products was estimated approximately at 3,966,000 TOE. Among the agricultural by-products examined, rice straw showed the greatest energy production potential being at 2,321,000 TOE. Furthermore, it might contribute to establishing the countermeasures of biomass utility in agricultural sector based on regional distribution chart of the potential biomass and energy yields in Korea.

  • In Bangladesh, since the beginning of 21st century, the poultry industry has become an unparalleled platform for a quick profit, the generation of local employment, and the production of cheaper animal proteins. This paper summarizes poultry industry-related facts and figures for Bangladesh, starting from the very beginnings of this sector when poultry farming was part of subsistence family farming only to today's highly commercialized horizon, through personal experiences, secondary data analysis, spot visits, and the sharing of views and ideas with stakeholders. A critical analysis reveals that the poultry industry in Bangladesh may become multi-dimensional and more stable in the near future as it establishes sufficient backward and forward linkages to input and output supplies. We can foresee its passing the very fast growing juvenile stages of higher net profit earning and less responsible then becoming fully mature. The projected demand and production potentials of this sector are increasing, but at a slower pace than before, in the face of some important challenges like emerging disease, higher prices of inputs, consumer preferences, and strong market competition. However, evidence suggests that the production systems of poultry in Bangladesh are entering a new era to cater to the needs of consumers, society, and government as it produces healthier and more diversified, further-processed foods, in the coming years. A better economy in the country, a more health-conscious population, and the availability of new and affordable innovations in this sector might be the driving forces to support the foreseen transformations.

  • 저렴한 농사용 전력 요금으로 인한 농업 부문 전력 과소비, 에너지의 전력 의존도 증가, 전력 생산성 저하, 교차보조의 증가 등 부작용들이 심화되고 있다. 더구나, 저렴한 전기 요금의 혜택이 영세농이 아닌 기업농에 집중되고 있으며, 최근에는 가상통화 채굴에 농사용 전기가 불법 사용되는 사례가 늘고 있다. 본 연구는 이러한 부작용을 분석하고, 로그평균 디비지아 지수법(LMDI)을 이용하여 1988-2016년 농사용 전력 소비량 증가를 성장, 구조 변화, 에너지 집약도 변화 등 세 가지 요인으로 구분하여 각 요인별 영향을 추정한다. 본 연구는 현행 농사용 전력요금 정책이 여러 가지 부작용을 낳고 국가 에너지 수입 부담을 가중시키며 온실 가스 배출 증가 억제에 부정적인 만큼 근본적인 변화가 시급함을 알려준다.

  • In 2014, the United Nations Framework Convention on Climate Change (UNFCCC) agreed to submit the Intended Nationality Determined Contributions (INDCs) at the conference of parties held in Lima, Peru. Then, the South Korean government submitted the INDCs including GHGs reduction target and reduction potential on July, 2015. The goal of this study is to predict GHGs emission and to analyze reduction potential in agricultural sector of Korea. Activity data to estimate GHGs emission was forecast by Korea Agricultural Simulation Model (KASMO) of Korea Rural Economic Institute and estimate methodology was taken by the IPCC and guideline for MRV (Measurement, Reporting and Verification) of national greenhouse gases statistics of Korea. The predicted GHGs emission of agricultural sectors from 2021 to 2030 tended to decrease due to decline in crop production and its gap was less after 2025. Increasing livestock numbers such as sheep, horses, swine, and ducks did not show signigicant impact the total GHGs emission. On a analysis of the reduction potential, GHGs emission was expected to reduce $253Gg\;CO_{2-eq}$. by 2030 with increase of mid-season water drainage area up to 95% of total rice cultivation area. The GHGs reduction potential with intermittent drainage technology applied to 10% of the tatal paddy field area, mid-drainage and no organic matter would be $92Gg\;CO_{2-eq}$. by 2030.

  • The negative impact of climate change on the agricultural sector is rapidly increasing, and it is urgent to prepare policies at the government level to mitigate it. In the case of Rwanda's agricultural sector, which lacks the government's budget and farmers' capital, efficient and effective policy implementation is of paramount importance. To this end, rather than establishing related policies in the public sector from the top down, it is necessary to establish a bottom-up customized policy that is reflected in policy establishment by identifying the characteristics and behaviors of farmers who actually participate in adaptation activities. In this study, the effects of farmers' characteristics and farmers' perception status/adaptation status to climate change on the selection of adaptation methods for climate change were analyzed. 357 rice farmers randomly selected from Eastern Rwanda were surveyed to explore the information related to farmers' perception to climate change and adaptation methods as well as basic information of the farm. Research shows that the probability of selecting a variety of adaptation methods rather than not responding to climate change increases the younger the age, the higher the education level, and the easier access to climate information and credit. As a policy proposals, it is judged that public support such as strengthening agricultural technology support services, including more detailed guidance for elderly and low-educated farmers, and improving access to farm loan services by agricultural financial institutions is needed. In addition, it is necessary to adjust the planting time and cultivation method, provide timely information related to climate change, and provide crop variety improvement services to farmers.

  • Agriculture and the rural sector play a crucial part in Vietnam's socio-economic growth. The study's goal is to see how technology transfer from young intellectual research activities affects the economic evolution of Vietnam's agriculture and rural sector in the 4.0 technology era. The research has used a quantitative method through analysis of linear structural model SEM, with a survey scale including 480 samples that are managers in departments and branches in agriculture and rural sector in the provinces in Vietnam. Research results show that technology transfer from research activities of the young intellectual has a direct and positive impact on economic development in agriculture and rural sector. This level of impact will increase with the participation of the intermediary factors such as awareness of managers, trust, and mechanisms in the mobilization and use of resources. These results contribute to both theoretical and practical aspects when proving the impact of technology transfer from the research activity of the young intellectual to the economic development in the field of agriculture and rural sector in the 4.0 era and the mediating role of awareness of managers, trust and mechanisms in the mobilization and use of resources.
