2012년 농림수산 식품부 자료에 따르면 국내 식용 옥수수 재배 면적은 약 15,000 ha, 생산량은 74,399 톤이며, 옥수수의 식량 자급률은 3,8%, 곡물자급률은 0.9% 내외로 소비량의 대부분을 수입에 의존하고 있다. 옥수수 전체 수입량의 75%가 사료용, 23%가 가공용으로 국내 사료 및 산업소재로서 중요한 위치를 차지하고 있지만 옥수수 수입대체 및 품종 개발과 관련된 국내 연구는 내수를 위하여 제한적으로 수행되어 왔기 때문에 그 동안 축적된 기술을 바탕으로 종자시장이 협소한 국내보다는 해외를 대상으로 한 기술 개발이 시급하다. 현재 동남아시아는 외국 투자 유치를 자국 경제 발전의 원동력으로 삼고 외국인 투자자에 대해 면세혜택까지 부여하며 각종 지원책을 내세워 투자를 유도하고 있다. 최근 동남아시아의 경제 성장과 더불어 노동임금과 토지임대료가 올라 농업이 점점 어려워진다는 얘기도 있지만 농업 기계화와 선진 영농을 접목시켜 노동생산성을 높이면 우리나라보다는 발전의 여지가 많이 남아있는 땅이다. 특히 세계적으로 축산물 수요가 증가하는 가운데 옥수수를 이용한 가공식품 및 사료작물의 활용은 좋은 아이템이 아닐 수 없다. 따라서 동남아시아를 대상으로 하는 해외식량기지로서의 가능성을 타진하고 해외 수출용 옥수수 품종을 개발하여 개발 품종에 대한 마케팅 판매 전략의 수립을 목적으로 진행된 결과는 다음과 같다. 1. 동남아시아의 주요 곡물 생산량 중 옥수수의 생산량은 1990년대를 기점으로 가축 사육 증가와 더불어 지속적으로 증가하고 있으나 옥수수 재배 농가의 재래종 사용 및 농사를 위한 기본 인프라 시설과 열악한 관개시설, 수확 후 관리기술의 미흡으로 단위면적당 생산성은 낮은 편이다. 최근 급속한 기후 변화로 인한 수량감소도 생산성을 저해하는 중요한 요인으로 작용하면서 내재해 다수성 교잡종 품종의 수요 및 요구도가 높아지고 있다. 2. 인도네시아는 1992년부터 3계교잡을 이용하여 개발된 품종이 보급되기 시작하여 2001년 부터는 단교잡 품종을 개발하여 보급하고 있고 캄보디아는 사료용 옥수수의 거의 대부분을 CP 캄보디아가 농가로부터 수매하여 사료를 제조하고, 농가는 이 회사로부터 옥수수 종자를 구매하여 재배하는 상호 유기적 관계를 유지하고 있었다. 2010년 이후 캄보디아의 주요 재배 품종은 몬산토의 DK8868, DK9955, 신젠타의 NK6326, NK7328, CP그룹의 CP333 등 여전히 다국적 기업 및 현지 로컬 기업의 품종이 재배되고 있었다. 베트남은 동남아시아에서 많은 양의 옥수수를 수입하는 대표적인 국가 중 하나로 1990년부터 2011년까지 평균 수입량이 수출량의 13배에 달한다. 또한 경제성장 및 육류소비의 증가로 인한 사료용 옥수수의 수입으로 베트남의 옥수수는 주변 국가에 비해 높은 시장 가격을 형성하고 있다. 이에 베트남 정부는 정책적인 투자로 생산 효율성 향상을 위해 LVN-10과 같은 다양한 개량종 품종을 개발하고 있을 뿐 아니라 해충저항성, 제초제저항성 품종과 같은 GM작물의 재배를 승인 하였다. 이는 2020년까지 지속가능한 농업을 장려하는 계획과 맞물려 GM작물을 30~50%까지 늘려 농산물의 품질을 개선하여 농촌소득을 증진시킬 계획이다. 3. 국내의 협소한 종자 시장 한계를 극복하기 위해 동남아시아에 우리 농업관련 기관이나 민간기업 등이 진출하려면, 현지의 투자환경과 여건을 사전에 조사하고 외국인과 외국기업에 관련된 법규 및 사례를 충분히 검토하여야 한다. 세계 굴지의 종자회사인 몬산토, 듀퐁, 신젠타 뿐 아니라 로컬 기업이 장악하고 있는 시장으로의 진입을 위해 기술, 품질 및 가격 경쟁력을 갖춘 신품종의 개발이 필요하다. 신품종의 개발은, 사전에 조사한 현지 시장 분석 마케팅 역량 및 정부의 투자지원 정책과 접목되었을 때 농산물의 해외 진출 성과를 기대할 수 있을 것이다.

The experiment was carried out to investigate the effect of extension of grazing duration in late autumn on grass growth in following spring, in order to improve the rate of self-sufficiency for roughage feed. Plant height, total biomass and litter production of herbage were increased when the grazing was finished early in late autumn. The proportions of clover and litter, and amounts of animal intake were decreased, with extended grazing duration in late autumn. But when the grazing was finished late in autumn, the contents of crude protein (CP, %) of herbage were increased, contents of acid detergent fiber (ADF, %), neutral detergent fiber (NDF, %) and crude ash (%) were decreased in pasture after grazing, therefore the contents of total digestible nutrients (TDN, %) and relative feed value (RFV) of herbage were improved. The early end grazing showed that plant height, total biomass and litter production of herbage in following spring were higher than those in late end grazing. However, increased yields were not significantly different among end grazing treatments (0.12-0.15 tonha), except for the final end grazing in late autumn (0.01 tonha). With extended grazing duration in late autumn, the contents of CP of herbage in following spring were increased, contents of ADF, were decreased, and RFV were improved.

Self-sufficiency rate of food in South Korea is almost at the lowest level among OECD countries, and the decrease tend of farmland is expected to be continued. In this situation, Korea experienced a rapid change in the international price of grain due to changes in amount of grain production and food weaponization. It also started to reinforce the appropriateness of maintenance of farmland above certain standard. As one of policy means for this situation, this study selected "the use of idle farmland" as a subject, and started to consider the way to suggest the policy projects using idle farmland. The result of this study is summarized as follows. Firstly, this study defined the meaning of idle farmland, and set up the scope of idle farmland needed to this study. Secondly, this study analyzed the domestic major policy projects with prevention function of idle farmland as well as the policy projects related to idle farmland. It also investigated "recycling measures of idle farmland" that is recently promoted in Japan, and deducted the direction for developing a new model. Lastly, It suggested 9 policy project models that are finally able to use idle farmland. Suggested models are designed to access from various directions. This study suggested contents, entity, target and characteristics of projects in order to set up proper directions in promoting policy projects using idle farmland.

The most limited production resource in Korea is land. During the period from 1995 to 2002, annual farm land area of 17,600ha have been converted to urban and industrial land. The self-sufficiency rate of rice, Korean staple food, is expected to be decreased from 97.5% in 2003 to 60-70% in 2020. Under such conditions, this study is aimed at first identifying multi-functional benefits of the reclamation projects such as agricultural production, industrial water supply, urban land supply, transportation effects, sightseeing effects and environmental values with and without the projects. To carry out the objectives, three existing tideland reclamation projects such as Daeho, Kumgang and Yongsangang irrigation project stage II were evaluated and Saemangeum tideland reclamation project which was jointly revaluated by environmental NGO and Govn't appointed specialists in 2000 was reviewed. According to this study results, tide land reclamation projects were showed financially and economically feasible and environmentally sustainable. The joint cost like estuary dam should be allocated based on the multi-functional benefits of the projects. To allocate the joint cost, legal and institutional improvement should adapt the joint cost allocation method as the specific cost-remaining benefit method. Korea has more than 402,000 ha of tidal flat of which 76,396ha have been reclaimed in 2003. To meet food security and to cope with shortage of land, phil-environmental reclamation projects should be continuously implemented and necessary tidal flats for protecting environmental ecosystem should be remained according to the detail survey results of reclaimable resources.

South Korea is largely dependent on imports of forage crops. In order to raise the self-sufficiency rate of forage crops, it is necessary to cultivate forage crops in 135,100 ha reclaimed land of South Korea. This study was conducted to investigate the growth of halophytes and forage crops in order to search for stable plants on reclaimed land. The plants were cultured in Hoagland solution and grown at 0%, 0.5%, 1.0% and 2.0% of salt concentrations. Plants with good growth at 0.5% of salt concentration were halophytes such as Suaeda asparagoides and Salsola komarovii. Salicornia herbacea and Suaeda maritima showed good growth at 2.0% salinity, and Suaeda maritima showed stable growth at all of salt concentrations. In conclusion, Suaeda asparagoides showed the best growth at 0.5% of salt concentration and was considered the most biomass at reclaimed land in Korea with less than 0.5% of salt concentration.

Food consumption pattern changes, including a decrease in rice consumption and increasing demand for fresh vegetables, along with declining food self-sufficiency rate, more importance is being placed on agricultural industry within Korea. Taking these changes into consideration, there is an increasing necessity for managing upland fields on agricultural sector to revitalize agricultural land use. Therefore, in this study, upland use type was classified into agricultural economic, environmental conservation, and rural social frames. The purpose of this study was to suggest upland use plan with farm manager registration information and spatial data. As results of this analysis, the mean area of agricultural economic frame in Haenam (16.47 ha) was found to be wider than Muan (3.17 ha), and scale improvement zones (54 zones) were located in only Haenam. In case of environmental conservation frame, there's no zone of scenic agriculture land in both study areas, but landuse transition zones were located in Muan (278 zones) and Haenam (604 zones). Agro-healing zones of rural social frame were 1,018 zones in Muan and 1,588 zones in Haenam and kitchen garden sites were 342 zones in Muan and 370 zones in Haenam. These results could be used when we establish the plan of an agricultural infrastructure project or select places for a collaborative agricultural land use project.

Objectives: This study was performed to investigate the associations of food security with socio-demographic characteristics, nutrient intakes and mental health status among older Korean adults. Methods: This study was conducted using data from the 2008-2010 Korea National Health and Nutrition Examination Survey (KNHANES). Subjects were 4,451 adults aged 65~98 years. Food security was measured using a self-reported question on food sufficiency of subjects' household. Based on the answers, study subjects were classified into secure, mildly insecure, moderately insecure, and severely insecure groups. Dietary intake was estimated by 24-hour dietary recall. Nutrient intake was assessed by dietary reference intakes (DRI). As for mental health status, the data on mental stress, depression, and suicide ideation were used. Results: Rate of food insecurity in older adults was 14.3%. Old age, being female, low education, low income level, living alone, and discomfort in daily living were more related to food insecurity. Means of nutrient intakes were significantly different according to food security status. Intakes of calcium, potassium, and vitamin $B_2$ were lower than recommended intakes in all groups. Consumption amounts of soy and soybean products, vegetables, mushrooms, fruits, vegetable oils, meats, eggs, seafood, and dairy products were lower in food insecure groups. Mental stress, depression, and suicide ideation were higher in food insecure groups independent of the gender and income level. Conclusions: These present findings suggested that food security is related to mental health as well as nutrition status in older Korean adults. A national system that include food and psychosocial support programs for the elderly should be considered in order to improve the overall health of older Korean adults.
