Crop inputs in excess of the yield potential of the soil type reduce profitability and increase pollution problems from leaching and runoff. Inaccurate fertilizer and pesticide application can also result in profit loss. Current farming practices plan only for the dominate soil in the field. A government-supported program titled "Pilot village project for the environment-friendly agriculture" was proceeded from 1999 to 2001 to tackle the problems with which our agriculture is faced by introducing IPM, INM and others. The objective of this study is to consider the potential input savings of agricultural chemicals and economic feasibility of the project compared with the conventional farming. The results of the analysis indicate the followings: (1) organic or no-pesticide farming size was increased from 9% in 1999 to 20% in 2001 ; (2) crop yield was a link bit lower than that of the conventional farming, but the sal6 price, gross income and income of the pilot village were 6%, 10% and 9% higher than that of the conventional farming, respectively; and (3) fertilizer and pesticide use also showed decreasing trend gradually.

유기농업이 생물 다양성에 미치는 효과가 제한적이라는 일부 회의적인 시각이 있긴 하지만, 유기농업은 토양의 물리적 및 생태학적 특성과 생물 다양성에 영향을 미치는 것으로 받아들여지고 있다. 본 연구는 충청북도 괴산지역에서 유기농업과 관행농업을 시행하는 논과 밭을 대상으로 경작 기간 중 채집된 무척추동물의 종을 분류 동정하여 농법의 차이에 따른 생물 다양성의 변화를 비교 분석하였다. 조사 기간인 2016년 6월부터 10월까지 채집된 총 249종의 무척추동물 중에서, 유기농업을 시행하는 지역의 논과 밭에서는 각각 104종과 108종이 관찰된 반면, 관행농업을 시행하는 논과 밭에서는 각각 84종과 77종이 관찰되어, 산술적으로 관행농업 지역에 비해 유기농업 지역의 종 다양성이 약 20% 높은 것으로 비교되었다. 특히 유기농업의 시행에 따라 곤충류와 거미류의 분류군에서 긍정적인 종 다양성 변화가 관찰되었다. 한편, 유기농업 논에서는 노린재목, 파리목, 벌목, 거미목 등의 분류군이, 그리고 유기농업 밭에서는 노린재목, 딱정벌레목, 거미목 등이 관행농업 지역의 논과 밭에 비해 생물 다양성이 증가하는 것으로 분석되어, 유기농업 시행에 따른 생물 지표종의 선정을 위해서는 향후 이들 분류군에 대한 정밀한 조사가 필요할 것으로 생각된다.

This study was carried out to present the measures for the stable organic rice production, farm income increase and consumption revitalization and so on by analyzing economic effects of the organic rice production complex and farmers by cultivation type. The farmers received prices of organic rice and Life and Environment Agriculture (LEA) were 2,965 won and 2,014 won per kilogram, respectively. Finally, the results of the productivity analysis show that LEA produces about 11% lower crop yield compared with the conventional farming. Meanwhile, the profitabilities of the organic farming per 10a were about 15% higher than the conventional farming. But, LEA per 10a was individually 23% lower then the conventional farming.

Organic kiwifruits were smaller fruit size but had higher magnesium and dry matter content than conventional, meanwhile, fruit soluble solid content was similar to conventional. There were no significant difference in polyphenol contents and antioxidative capacity between organic and conventional although there were considerable variations among sample orchards. Several minerals were also similar levels in both systems.

In the paper, the actual situation of Korean organic agriculture and its development history regards to basic skills of organic farming were reported. And an education for organic farming in the universities with schools of agriculture in European countries was also reported to deliver the information on the course of organic agriculture for Korean Universities facing the problem which have a lower admission competition than previous Year. The examination for organic engineer certificate which was introduced in 2001 and the proposed government research institute, so called "Research Center of Organic Agriculture" were also shortly discussed. In the conclusion, \circled1 the establishment of "research Center of Organic Agriculture" which should by attached RDA for the systematic approach of research for organic agriculture and the test of agricultural materials using for organic farming, \circled2 department of organic agriculture in the Universities with schools of agriculture to offer next generation an opportunity to learn an organic farming parallel to conventional farming, \circled3certification body system by third party, and \circled4 full support by Korean government and scientist society for "Asian Research Network of Organic Agriculture (ARNOA)" headquartered in Korea as international research organization were strongly suggested.

This case study surveyed management situations of environmentally friendly farming (EFF) and their awareness situations. Farmers are aging as an average age of 62-year old. The EFF did not increase farmer's income, however, farm income of EFF was more than that of conventional farming. Farm household liabilities showed large deviation among farmers. Livestock and greenhouse farm households have more liabilities because of facilities and feed cost. Farmers of EFF have been also cultivating conventional farming, but they don't plan much conversion intention of conventional farming into EFF owing to lack of differentiated and stable market for their environment-friendly agriculture products. And they are guessing that EFF income will usually not increase more. For increasing of EFF income, they think that it is necessary to enlarge production area, change to high-income crop, develop processing foods, change to organic farming and so on.

This study analyzes an economic efficiency of environmental friendly farm and conventional farm using the data envelopment analysis (DEA). We compare the economic efficiency of Environmental Friendly farm and Conventional farm. We also analyze the effects of some explanatory variables on allocative efficiency (AE), pure technology efficiency (PTE) and scale efficiency (SE). In the case of strawberries farm, environmental friendly farm has higher overall efficiency (OE) than conventional farm. But tomatoes farm has higher overall efficiency (OE) than conventional farm. And We measure returns to scale of farms. Most strawberries and tomatoes farms showed Increasing to Scale (IRS).

The contents of functional components in the organically agricultural perilla leaves were compared with the perilla leaves grown in conventional condition. Perilla leaves used in the experiment were purchased or harvested from each three organic farm houses and conventional farm houses in Miryang city. The analyzed components included total phenol, total flavonoid, vitamin C, vitamin E, ${\beta}$-carotene, GABA, caffeic acid, rosmarinic acid, Total N, Zn, Fe, Ca, Mg, Na, K, and P. Organically grown perilla leaves had vitamin E 49% greater than the conventional perilla leaves, and 21% for TN, 29% for Ca, and 73% for Mg, while conventionally grown perilla leaves contained K 16% higher than organic ones. Other components were not showed the differences.

Eco-efficiency which is calculated by dividing economic productivity by the environmental load was made by synthesizing eco and efficiency from ecology and economy, proposed by World Business Council for Sustainable Development in 2000. Eco-efficiency by connection of resource efficiency with resource intensity is used as an indicator for evaluating green growth for minimizing the impact on the environment and achieving economic development as well by means of efficient use of resources. This research analyzes eco-efficiency with the case of organic agriculture promoted as a key green growth policy. Thirty questionnaires for farmers producing organic rice in Hongseong-gun, Choongcheongnam-do were used for the analysis. Eco-efficiency was measured by means of the amount of used nitrogen with respect to the amount of income, and was represented that organic agriculture was 32.0 higher than conventional agriculture. The analytical result of technical efficiency, using the (Data Envelopment Analysis (DEA) model showed that it is 0.765 which has a possibility of 21% in management improvement, and higher eco-efficiency was with higher technical efficiency. The analytical results showed that an organic agriculture contributes to green growth more than conventional agriculture. In addition, higher technical efficiency groups exhibited higher eco-efficiency indices.
