The purpose of this study is to conduct a pilot study on estimating rice yield by using satellite images. Many developed countries including the United States and the European Union have been using satellite images to produce agricultural statistics and outlook analysis. In Korea, some institutions have used satellite images for their analysis. In this paper, we estimated rice yield by using satellite images. We choose rice on this study as one of target commodities. Because the yield of rice can easily be identified by using remote sensing technology. and Among the satellite images, MODIS satellite images were used, since these were free and widely used for estimating yield of major crops such as rice, wheat, soybean and or so in many countries. The method used to classified national area for estimating national rice yield was based on a simple correlation between the county rice yield statistics and the county average NDVI(Normalized Difference Vegetation Index) extracted from Satellite images. We found that the accuracy of estimating yield depended on an average temperature for one year. So We divided a nation into 5 sectors with isotherm and tried to develop 5 yield functions with NDVI. This study showed that remote sensing technology can actually be used to estimate rice yield. However, There is also a problem to get the clear MODIS images in appropriate time because these were easily affected by cloud. To solve this problem, it is necessary to consider using Radar Satellite images or alternatives.

With rice tariffication in 2014 and the signing of the Korea-China FTA in 2015, Korea concluded free trade agreements with most major countries including the US, the EU, and China, finishing one stage of the agricultural sector’s market opening. In an era of full market opening, this study aimed to establish a vision of the future of Korea’s agriculture, rural communities, and food industry and present each field’s tasks for development and regional development strategies. For this research, we conducted a SWOT analysis of the future environment of agriculture, rural areas, and the food industry based on the results of previous studies and the expert forum, and derived the vision and tasks for development. We utilized KREI-KASMO, the Korea Rural Economic Institute’s agricultural outlook model to calculate the estimates of indices for 20 years related to farming and rural regions. To analyze the order of priority of the tasks and the vision, we carried out in-depth expert research and employed AHP. To draw regional development strategies, we commissioned a study to universities and research institutes in three areas. We set the following vision of the future of agriculture, rural communities, and the food industry in 20 years: “the sustainable agri-food industry and livable rural areas.” Among the directions for development of each field, “stable supply of safe agri-food” took priority over “future growth industrialization of agriculture,” “environment conservation and maximization of multifunctionality of farming and rural regions,” and “a reduction in the urban-rural gap and the creation of livable rural communities.” This accords with the public opinion survey results, implying that the government policy direction should put top priority on constructing a stable supply system of safe food. As tasks by field for achieving the vision of agriculture, rural areas, and the food industry, training leading agricultural players and human resources, establishing a management system of safe agricultural and livestock products, and creating rural jobs were given priority in terms of both importance and urgency. Therefore, the government should also place top priority on nurturing enterprises that will lead future agriculture, building the safety control system, and creating jobs in rural regions. For regional development strategies, Chungcheongnam-do should set up a food-centered plan to construct a regional circulation system of agri-food, and should strengthen an independent committee’s governance function to link existing policies and projects, agents, sectors and fields. For the function of governance, capacity building is important and educational activities for it need to be reinforced. For Jeollanam-do’s agricultural development, it will be effective to pursue a strategy for safe, economic, and eco-friendly agro-food by promoting environment-friendly farming. To strengthen environmentally friendly agriculture, it is necessary to reinforce education for enhancing farmers’ will to practice and sense of responsibility, nurture talents, and improve a system for developing and disseminating organic farming technologies. The farms in Gyeongsangnam-do are actively cultivating new items such as subtropical fruit and vegetables. This province needs to pursue its development by building a regional innovation system. Regional innovation can result from research dissemination in the field through close cooperation between local agricultural policy and universities and research institutes with expertise and human resources.

연구는 오차수정항을 포함한 ARDL(Autregressive Distributed Lag Model) 모형을 이용하여 농산물의 도매와 소매단계(대형마트, 재래시장) 가격전달의 인과관계 및 장·단기적 가격 조정의 비대칭성이 존재하는지 여부를 분석하였다. 분석대상은 국내 4대 양념채소(양파, 깐마늘, 대파, 생강)이며, 자료는 2012년 1월부터 2022년 12월까지 일별(주 5일) 및 주별 가격을 이용하였다. 가격전이 비대칭성 분석결과, 양념채소류의 도매가격과 전통시장 가격 사이에서의 단기에 분배시차 비대칭이 품목과 시차에 따라 양(+) 또는 음(-)으로 혼재되어 나타난 반면, 도매가격과 대형마트 가격 사이의 단기 비대칭성은 양파(일별), 생강(주별)을 제외하고 확인되지 않았다. 즉 단기에는 도매가격의 변화가 대형마트보다는 전통시장에서 비대칭적으로 전이되고 있음을 확인할 수 있었다. 한편, 장기에서 누적충격 비대칭은 전통시장에서 대파의 주별 모형을 제외하고 대부분 양(+)의 비대칭적 가격전이가 확인되었다. 양(+)의 비대칭을 보인 것은 도매가격이 상승할 때는 소매가격은 빠르게 또는 더 상승하는 것으로 분석될 수 있으며, 가격 비대칭 전이가 발견된다는 것은 발생된 이윤이 균형적으로 배분되지 않고 있으며, 농산물 시장이 비효율적으로 작동된다고 볼 수 있다. 최근 국제유가 및 농축산물 가격 상승으로 소비자물가가 지속적으로 상승하고 있는 상황에서 소비자물가 상승을 완화하기 위해서는 비대칭적 가격전이가 발생되는 품목의 도매가격 상승을 최소화할 필요가 있다.
