  • Chinese cabbage is a staple food to Korean, which has the high degree of self-sufficiency and worldwide breeding technique in the aspect of seed. However, the producers' competitiveness has been decreasing after the agricultural product market was open. In order to cope with this problem, the government introduced some policies for promoting seed industry in 2007 to reflect producer's needs for high quality seeds of Chinese cabbage. These policies will be a good opportunity for producers to secure and promote the producers' competitiveness against low-price importing Chinese cabbage. In this aspect it is very important to know how well these policies are established and what Chinese cabbage farmers want in regard to a new variety of Chinese cabbage seed. This study was carried out to look over the Chinese cabbage producers' using pattern about a new variety of seed and show some directions for efficient way of diffusion of a new variety of seed to producers using a survey research. The main results are as follows. The producers thought the characteristics of a new variety of seed most important factor compared to other factors such as the seed price, and easiness of cabbage sales when they choose a seed. Also, the 65% of respondents were willing to accept a new variety of seed and thought the government support for an exhibition field and diffusing public information about a new variety of Chinese cabbage seed are important in accepting a new variety of seed.

  • 가상수는 Allan에 의해 1993년 처음 도입된 개념으로 모든 재화나 서비스를 생산하기 위하여 사용된 물의 양( /kg)을 의미한다. 예를 들어 1차 농산물의 경우 생육기간동안 농산물이 필요로 하는 물의 양이 가상수로 사용되고, 가공품의 경우 가공과정을 거치며 소비되는 물의 양이 가상수에 포함된다. 이러한 가상수의 개념을 활용한 소비 기반 물사용 지표가 물발자국이며 이는 2002년 Hoekstra에 의해 도입되었다. 물발자국은 개인이나 지역, 집단 등이 소비하는 재화와 서비스를 생산하는데 필요한 물의 총량을 나타낸다. 우리나라와 같은 물 부족 국가에서는 농 축산물 관련 정책의 수립 시 정량적인 생산량뿐만 아니라 소비되는 물의 양도 동시에 고려할 필요가 있다. 특히 현 정부는 2015년 식량자급률 목표치(곡물자급률 25%, 육류자급률 71%)를 설정하여 농 축산물의 생산 및 수입량을 조정하고자 한다. 이러한 식량자급률의 목표치에 따라 국내 생산 및 수입량의 비율이 변화하게 되므로 국내 물발자국의 값도 변화하게 되며 이는 수자원 정책 수립 시 주요한 요인으로 작용할 수 있다. 그러므로 식량자급률의 변화에 대해 단순히 생산량의 관점뿐 아니라 물 소비 절약의 관점에서의 접근이 필요하다. 이에 본 연구에서는 2015년 정부의 식량자급률 목표치 달성을 위하여 각 품목별로 소비되는 가상수의 양을 정량적으로 산정하고, 국내적으로 소비 또는 절약되는 가상수의 양을 추정하고자 하였다. 추정된 결과를 바탕으로 식량자급률 목표치에 따른 생산량의 조정으로 인한 물발자국의 변화와 그 영향을 파악하고자 하였다. 본 연구를 위하여 식량 자급률 목표치 설정에 포함된 농 축산물의 단위 가상수량과 생산량 추이, 목표 생산량 등을 조사 하였다. 이중 곡물의 단위 가상수량은 국내의 실정을 적용한 국내 연구결과를 활용하였으며, 축산물의 단위가상수량은 음용, 세척을 위한 원단위 필요수량과 소비되는 사료의 재배를 위한 단위 가상수량을 활용하여 전체 축산물의 가상수량을 산정하였다. 조사, 산정된 자료를 활용하여 2015년 식량자급률 목표치 달성을 위해 필요로 하는 가상수의 변화량과 국내적으로 소비 또는 절약되는 가상수의 양을 파악하고자 하였다.

  • Sustainable wheat production is of paramount importance for attaining/maintaining the food self-sufficiency status of the rapidly growing nation of Pakistan. However, the average wheat yield per unit area has been dwindling in recent years and the climate-induced variations in rainfall patterns and temperature regimes, during the wheat growth period, are believed to be the reason behind this decline. Crop growth simulation models are powerful tools capable of playing pivotal role in evaluating the climate change impacts on crop yield or productivity. This study was aimed to predict the plausible variations in the wheat yield for future climatic trends so that possible mitigation strategies could be explored. For this purpose, Aquacrop model v. 4.0 was employed to simulate the wheat yield under present and future climatology of the largest agricultural province of Punjab in Pakistan. The data related to crop phenology, management and yield were collected from the experimental plots to calibrate and validate the model. The future climate projections were statistically downscaled from five general circulation models (GCMs) and compared with the base line climate from 1980 to 2010. The model was fed with the projected climate to simulate the wheat yield based on the RCP (representative concentration pathways) 4.5 and 8.5. Under the worst, most likely future scenario of temperature rise and rainfall reduction, the crop yield decreased and water footprint, especially blue, increased, owing to the elevated irrigation demands due to accelerated evapotranspiration rates. The modeling results provided in this study are expected to provide a basic framework for devising policy responses to minimize the climate change impacts on wheat production in the area.

  • Vaccination is the most powerful and useful preparation against infectious diseases. However, developing vaccines costs a lot and requires extensive long-term efforts. Therefore, the government should research and develop vaccines with a national-level policy. To greatly enhance the success rate of vaccine development, the policy should be set up considering priorities such as the current status of domestic research, the importance for public health, the urgency of research. The Delphi technique was utilized to draft this survey, through a brainstorming stage, then two inquiries, and finally the final panel meeting where unresolved items were discussed, to draw the conclusion. Among the results, firstly, the highest ranked item on centralized fields for vaccine development by the Ministry of Health was 'self-sufficiency of vaccines.' Secondly, 'emerging infectious disease' was most highly ranked in prioritized fields of vaccine development and research. Thirdly, for the vaccine that needs to be improved and developed further by the government to improve its efficacy and safety, BCG (Bacille de Calmette) for tuberculosis was ranked the highest on both types (intradermal and subcutaneous injection) from National Immunization Programme (NIP) and non-NIP. As for the high risk pathogens, 'anthrax' and 'smallpox' were first and second, consecutively. Lastly, 'development and control of vaccine candidates' was ranked the highest for the area in need for technique development in order to improve domestic vaccine's research level. The results of this study will be put to good use as basic data for the national vaccine research and development (R&D) policy of the country. This study was first step and more studies should be carried out for the final decision of the national vaccine R&D priority.

  • The purposes of the study were to; 1) examine the diffusion and adoption of new agricultural technology in rice farming, 2) survey the status of agricultural education institutions on technology transfer, and 3) explore the linkages between agricultural education and extension for more effective reinforcement strategies to further the diffusion and adoption of new agricultural technology in Korea. Literature review, field survey and panel discussions were employed to strengthen the linkages among agricultural education, research and extension in Korea. As the results of analysis of the diffusion and adoption of new agricultural technology in rice farming following recommendations were offered; 1. Extension services have helped Korean farmers in achieving self-sufficiency in rice and year-round supply of green vegetables as well as upbringing rural youth, however, government changed the status of extension educators from central government staff to county/city government staff since 1997. This brought about various problems such as: decreased morale and number of extension educators, thus weakening the extension education function, weakened linkages between national and local extension offices, less opportunity for in-service education of extension educators, and weakened linkages between agricultural research and extension, etc. 2. In order to insure that extension educators are high caliber professional individuals, it is crucial to establish a system that nationally recognizes these individuals as such, and that provides a professional development path. It is important to restore the morale of extension educators to continually achieve the national goals of food production, balanced national development and preservation of environment, at the same time to meet increasing needs of farmers. 3. Because of the critical importance of diffusing innovations to agricultural producers in order to ensure quality and steady food supply, it is crucial that these issues be addressed before the extension service further deteriorates. Further research activities on agricultural extension should be conducted for more effective agricultural extension system in Korea to achieve a greater rural, national and regional development. 4. Research and implementation activities should be emphasized and encouraged to improve the cooperation and collaboration among agricultural education research and extension to better serve farmers' educational and information needs. National level research activities should be encouraged to improve the effectiveness of agricultural technology transfer including internet education programs for farmers in Korea.

  • This study aimed at finding directions for Korean agriculture to establish a new paradigm of sustainable development. Various problematic issues and concerns in the environment necessitate the transformation of Korea's development paradigm from unconditional growth to "Green Growth" through new policies on green value and review of various advanced researches. In this research, the environment-friendly agriculture's problems, particularly in agribusiness were analyzed. Drawing from Michael Porter's Value Chain Analysis, this research developed a value chain model in agriculture that reflects the environment and the present situations. Future directions in the agriculture sector were also discussed. Korea realized food self-sufficiency through the green revolution in the early 1970s. However, a lot of problems have also occurred, including ground and water pollution and the destruction of ecosystems as a result of the overuse of pesticides and chemical fertilizers. In the late 1970s, the growing interest on environment-friendly agriculture led to the introduction of sustainable methods and techniques. Unfortunately however, these were not innovative enough to foster environment-friendly agriculture. Thereafter, the consumers' distrust on agricultural products has worsened and concerns about health have increased. In view of this, the Ministry of Food, Agriculture, Forestry and Fisheries introduced in December 1993 a system of Quality-Certified Products for organic and pesticide-free agri-foods. Although a fundamental step toward the sustainability of the global environment, this system was not enough to promote environment-friendly agriculture. In 2008, Korea's vision is for "Low Carbon Green Growth" to move forward while also coping with climate change. But primary sectors in a typical value chain do not consider the green value of their operations nor look at production from an environmental perspective. In order to attain sustainable development, there is a need to use less resources and energy than what is presently used in Korean agricultural and value production. The typical value chain should be transformed into a "closed-loop" such that the beginning and the end of the chain are linked together. Such structure allows the flow of materials, products and even wastes among participants in the chain in a sustained cycle. This may result in a zero-waste sustainable production without destroying the ecosystem.

  • South Korea is pushing for the advancement of crop production technology to achieve food self-sufficiency and meet the demand for safe food. A medium-sized satellite for agriculture is being launched in 2023 with the aim of collecting and providing information on agriculture, not only in Korea but also in neighboring countries. The satellite is to be equipped with various sensors, though reference data for ground information are lacking. Hyperspectral remote sensing combined with 1st derivative is an efficient tool for the identification of agricultural crops. In our study, we develop a system for hyperspectral analysis of the ground-based reflectance spectrum, which is monitored seven times during the cultivation period of three soybean crops using a PSR-2500 hyperspectral sensor. In the reflection spectrum of soybean canopy, wavelength variations correspond with stages of soybean growths. The spectral reflection characteristics of soybeans can be divided according to growth into the vegetative (V)stage and the reproductive (R)stage. As a result of the first derivative analysis of the spectral reflection characteristics, it is possible to identify the characteristics of each wavelength band. Using our developed monitoring system, we observed that the near-infrared (NIR) variation was largest during the vegetative (V1-V3) stage, followed by a similar variation pattern in the order of red-edge and visible. In the reproductive stage (R1-R8), the effect of the shape and color of the soybean leaf was reflected, and the pattern is different from that in the vegetative (V) stage. At the R1 to R6 stages, the variation in NIR was the largest, and red-edge and green showed similar variation patterns, but red showed little change. In particular, the reflectance characteristics of the R1 stage provides information that could help us distinguish between the three varieties of soybean that were studied. In the R7-R8 stage, close to the harvest period, the red-edge and NIR variation patterns and the visible variation patterns changed. These results are interpreted as a result of the large effects of pigments such as chlorophyll for each of the three soybean varieties, as well as from the formation and color of the leaf and stem. The results obtained in this study provide useful information that helps us to determine the wavelength width and range of the optimal band for monitoring and acquiring vegetation information on crops using satellites and unmanned aerial vehicles (UAVs)
