This paper used the decomposition of Gini coefficients for the expenditures on food items and estimate their elasticities. We used the household expenditure survey data and examined changes in food expenditure elasticities for periods from 1982 to 2006. The results indicated that (i) Gini coefficients for all food items except dairy products, teas and beverages, bread & cookies, and food away from home has been increased, indicating that the inequality of the expenditures those food items has become greater, (ii) elasticities for all food items has been decreased over time, and (iii) expenditure elasticities for food items such as meats, vegetables, fruits, and food away from home began to increase since 2001, reflecting the increase in demands for high-quality or more value-added food products.

Variability in precipitation due to climate change causes difficulties in securing stable surface water resource, which requires understanding of relation between precipitation and stream discharge. This study simulated stream discharge in a small mountainous forested catchment using antecedent precipitation index (API) models which represent variability of saturation conditions of soil layers depending on rainfall events. During 13 months from May 2015 to May 2016, stream discharge and rainfall were measured at the outlet and in the central part of the watershed, respectively. Several API models with average recession coefficients were applied to predict stream discharge using measured rainfall, which resulted in the best reflection time for API model was 1 day in terms of predictability of stream discharge. This indicates that soil water in riparian zones has fast response to rainfall events and its storage is relatively small. The model can be improved by employing seasonal recession coefficients which can consider seasonal fluctuation of hydrological parameters. These results showed API models can be useful to evaluate variability of streamflow in ungauged small forested watersheds in that stream discharge can be simulated using only rainfall data.

농가가 영농활동을 하면서 이용할 수 있는 청정에너지는 현재 지열 및 공기열, 바이오가스, 목재펠릿 등이 있으며, 이들 에너지원은 경제성, 생산성, 환경적 측면 등 여러 가지 직간접적인 편익을 제공해 주기 때문에 대체에너지원으로 향후 중요한 역할을 할 것으로 기대된다. 본 연구에서는 농업부문에서 생산ㆍ이용하고 있는 청정에너지원별 운영실태와 문제점을 조사하고 사례조사를 통해 경영성과를 분석하여 에너지원별 보급확대 가능성과 발전 방안을 제시하였다. 정부는 저탄소 녹색성장 정책에 맞추어 화석연료의 대체에너지원으로 청정에너지를 보급ㆍ확대할 계획으로 다양한 시범사업 및 정책을 추진하고 있다. 농가조사에 따르면 지열 및 공기열 히트펌프는 기존 연료에 비해 경제성이 높은 것으로 나타났으며, 목재펠릿은 원료비의 영향으로 경제성은 아직 높지 않지만 생산성과 품질 향상 효과가 높다고 평가하고 있다. 하지만, 관련 시공 및 운영 기술 수준이 미흡하여 초기 설치비가 높고 이용효과의 불확실성이 높다는 문제점이 있다. 특히, 시설 설치부터 운영, 사후관리까지 인프라가 구축되지 못하였기 때문에 청정에너지의 생산ㆍ이용이 원활하지 못한 실정이다. 따라서 청정에너지 활용을 확대하기 위해서는 효율적인 지원정책이 무엇보다 중요하다. 우선 중앙정부 및 지자체 보조비율을 높여 사업참여 기회를 확대해야 하며, 정부지원 시 기계, 설비에 대한 보조보다는 청정에너지의 원료 및 초기 설치비, 기술개발에 중점을 두어 지원되어야 할 것이다. 또한, 연구개발을 통해 기술수준을 높임으로써 설비 운영에 대한 경제성을 높여야 한다. 이와 함께 설계와 시공을 통합하고 농가별 모니터링, 사후관리(AS) 등 전반적인 운영에 대한 일괄시스템을 구축할 수 있도록 전문업체를 육성하는 것이 필요하다. 끝으로 농업ㆍ농촌부문에서 청정에너지 생산ㆍ이용을 확대하기 위해서는 지역 고유의 특성을 반영한 신재생에너지 시스템 개발이 필요하다. 지역 내 자원을 최대한 이용하여 자급자족하는 자원순환형 농업은 이산화탄소를 절감하는 것뿐만 아니라 에너지 안보를 높이고 지역 경제의 활성화, 일자리 확대, 환경보호 등 전후방 연관효과를 창출할 수 있다. Clean energy can be used for farming activities and replace fossil fuels. In Korea, geothermal and air source heat pumps, biogas plants, and wood pellets are currently available for use in the agriculture sector. These energy sources are expected to play an important role in the future as they can provide direct and indirect benefits in terms of economy, productivity, and environmental aspects. The main goal of this research is to analyze the current shape of clean energy use in the agricultural sector and find out problems of management through research and case studies. Also, we present a few suggestions to improve the production and use system. The government plans to expand the use of clean energy as an alternative energy source to replace fossil fuels and, as part of this plan, it is promoting various pilot projects and policies such as the low-carbon green growth policy. According to a survey of farmers, the economy of geothermal and air source heat pumps is higher than that of the currently used fuels. The survey has also found that although wood pellets are economically infeasible because of high raw material cost, they are more effective in improving productivity and quality. However, there is a problem in that the initial installation cost is high due to lack of technical skills related to construction and operation, and the effect of its use is highly uncertain. Especially because there is no infrastructure for installation, operation, and follow-up control of clean energy facilities, the production and use of clean energy is limited. Therefore, efficient support policies are most important to maximize clean energy utilization. First of all, the opportunity to participate in alternative energy projects should be expanded by increasing the support scale of the central and provincial governments. Also, government support should be focused on lowering the initial raw material and installation cost and developing clean energy technology rather than on machinery and equipment. The economic feasibility of operating a clean energy facility should also be raised by increasing the technology level through research and development. And it is necessary to foster a professional supplier who can build a batch system for overall operation of the facilities from integrated design and construction to farm monitoring and after-sales services. Finally, in order to maximize the use of clean energy in agricultural and rural sectors, it is necessary to develop renewable energy systems that are unique to a region. The self-sufficient resource-recycling agriculture that best uses local resources can produce ripple effects in downstream and upstream sectors of the economy, including not only reduction of carbon dioxide but also increase in energy security, stimulation of local economy, creation of jobs, and protection of the environment.

Background of Research Agriculture plays a major role in bioindustry in that most of the essential raw materials that are used for development of the industry are extracted from by-products of agriculture. The main goal of this research is to identify the status of bioindustry in the agri-food sector, analyze investment and market size, technology level and technology development trends and suggest ways of developing bioindustry in the agri-food sector. Method of Research Bioindustry in the agri-food sector can be classified into four industry branches: Agro-Green Industry, Agro-Blue Industry, Fusion Agro-Green Industry, and Fusion Agro-Blue Industry. Also, an economic analysis was carried out using a variety of analytical methods such as Analytic Hierarchy Process(AHP) and the Delphi technique. Research Results and Implications The types of investment in bioindustry in agriculture vary among government departments. The Ministry of Education, Science and Technology invests mostly in industry infrastructure, whereas the Ministry of Health and Welfare, the Ministry for Food, Agriculture, Forestry and Fisheries, and the Ministry of Knowledge Economy are focused on investing in industry applications and production. The total market size of bioindustry in the agri-food sector increased 14% in 2010 from 2008. Also, the technology level of 7 industries promoted by the Ministry for Food, Agriculture, Forestry and Fisheries stands at about 66~68% level of developed countries and it is expected to increase to 80~82% level in 2014. According to the biotechnology patent activity index, the technology level jumped to the eighth place globally in 2010 from the 15th ranking in 1990. Also, a total of 93 agricultural patents were issued in 2010 by the Korean Intellectual Property Office and this represents a growth of almost six times from 1990. It was also found that bioindustry in the agri-food sector has great ripple effects. The market size is huge and the effects on inducing production and creating added value and jobs are also enormous. According to an AHP analysis conducted among experts, it was found that priority strategies for development of bioindustry in the agri-food sector are as follows, in order of urgency: bioindustry-related technology development(0.57), improvement of legal system and policy (0.29) and market expansion(0.15). First, the technology development of bioindustry should be focused on development of bio-resource application technology, development of evaluation capacity in association with bio-safety and bio-efficacy, development of technology related to analysis and use of genetic information, and development of genetic modification technology. In addition, bioindustry is a labor- intensive industry and thus it requires relatively skilled workers. Second, related laws and institutions should be improved to be in tune with the changing times. The work-overlapping problem is serious among different government ministries, and for this reason role division and collaboration of related ministries should be expanded to solve the problem. In conclusion, the top priority of the government should be placed on creating a favorable business environment for investors and on advancing commercialization of the technology and marketing of the product.
