Organic livestock farming in northern European regions has been expanded with the major animals of large ruminants using pastures and grass silages. Organic livestock farming in some European countries has been in rather short of productivity compared to the conventional livestock farming, however since the gap of productivity between organic and conventional livestock farming has been reported to be reduced when the efficiency of management would improve, organic livestock farming has a potential to develop as a clean livestock farming in the future. We expect that organic livestock farming be propelled to a future model of livestock farming in Korea too. As the schemes for realization of organic livestock farming in Korea, firstly a system for the consistent supply of organic feed should be established. Mountainous areas that represents 63 % of total area of Korea could be utilized for the production of organic forages. Uncultivated rice paddy and upland agricultural field could also be used for this purpose. The active application of organic agricultural by-products such as organic rice straw, organic rice bran and SO forth can be considered for organic livestock farming. Secondly, the replacement of anti-biotics for the management of animal diseases should be developed using natural products. Plants and microbes would be good sources of natural products. Thirdly, the realization of organic livestock farming may require a system for certification of the organic farms and consequently the experts to work on.

Organic farming systems based on ecological concepts have the potential to produce sustainable crop yields with no decline in soil and environmental qualities. Recent expansion of sustainable agricultural systems, including organic farming, has brought about need for development of sustainable farming systems based on value judgments for key properties of importance for farming. Chemical and microbiological properties were chosen as indicators of soil quality and measured at soil depth intervals of 5-20 and 20-35 cm in conventional and organic-based apple orchards located in Yeongchun, Gyeongbuk. The orchards were two adjacent fields to ensure the same pedological conditions except management system. Soil pH in organic farming was around 7.5, whereas below 6.0 in conventional farming. Organic farming resulted in significant increases in organic matter and Kjeldahl-N contents compared to those found with conventional management. Microbial populations, biomass C, and enzyme activities (except acid phosphatase) in apple orchard soil of organic farming were higher than those found in conventional farming. Higher microbial quotient ($C_{mic}/C_{org}$ ratio) and lower microbial metabolic quotient for $CO_2(qCO_2)$ in organic farming confirmed that organic farming better conserves soil organic carbon. Biological soil quality indicators showed significant positive correlations with soil organic matter content. These results indicate organic-based farming positively affected soil organic matter content, thus improving soil chemical and biological qualities.

This study is to analyze the demand for organic farming products . The demand for organic farming products is increasing rapidly but the study to analyze the demand system by the methods of econometrics is not tried at all because there is no any formal statistical data about the demand. Therefore, this study tries to estimate the raw statistical data to expect the demand trends of organic farming products in the future. To analyze the demand functions of organic farming products such as rice, bean, apple, grape, beef, and park, this study uses AIDS model by using several assumptions and estimates the price and income elasticities of the demands. The results demonstrate that the demands of organic farming products will be increased in the future and the prices of organic farming products will be the key factor in the demand, In 2004, the quantity demanded of the organic grape will account for 3% of total grape market. As a result, consumer's concerns about organic farming products will be high and the demand for organic farming products will be increased. Thus, the reasonable price system has a significant influence on the market of organic farming products.

Organic farming including organic livestock farming in EU has been extended since the latter half of the 19th century. Especially, the organic farming area of Italy, Spain, Germany and U.K. is extensive compared to other EU countries. And organic farming area has been extended rapidly in Portugal and Greece. EU will have an influence on many countries' organic farming on the history and world agriculture. If FTA reaches between Korea and EU, livestock products like ham or sausage will be imported a great deal from EU. So Korea has to establish countermeasures to livestock products export strategies of EU.

Soil physical properties in organic farming apple orchard were evaluated in relation to conventional farming to better understand the effects of organic farming system on soil quality. Two adjacent apple orchards, matched by soil type, were chosen to ensure the same pedological conditions except management system. Soil samples were collected from middle of two adjacent trees along the tree line at two depths of 5-20 and 20-35 cm in September 2006. Contents of organic matter in organic farming soil were twice as much as those found in soil of conventional farming. The higher level of organic matter in organic farming soil was reflected through a consequent trend in improved soil physical properties. Organic farming produced greater aggregation in >2 mm size and increased aggregate stability. Bulk density was lower by 13% and hence porosity was higher in soils of organic farming as compared with conventional farming. Water holding capacity was significantly greater with organic farming by >17% over conventional farming. The capacity of organic farming to improve soil physical properties can be contributed to the regular application of relatively large amount of organic materials and the sustainable ground-cover managements, mulching with compost and cover crop cultivation.

The EU recently adopted the policy for organic food and farming, Even though the EU enacted a regulation for organic farming in 1991, there has been no formal policy for supporting organic farming in the EU. This may mean that the EU regards the organic food and farming as an important sector for the future of European farming. Therefore, this study firstly explores the development processes and current situation of the EU organic food and farming policy, and then summaries the priorities of the EU organic food and farming sector. These were reflected to make up an action plan and a new regulation for the EU organic food and farming. The main features of the recent change in the EU policy would be the application of comprehensive perspective for dealing with organic food and farming issues.

The production practices, productivity and economic performance of organic and non-chemical rice farming were compared in Jeonnam Province, Korea. Korean organic rice farming showed a lack of use of resistant varieties and rotational cropping systems as well as less use of farm wastes and a high dependency upon external inputs. When compared with no-chemical rice production practices very little differences were found. However, organic rice farming showed 15% to 18% higher profits than no-chemical farming even though the productivity was arguably similar between the two farming types. This may encourage more farmers to convert to organic production rather than non-chemical farming as the farming practices are very similar, thereby resulting in increased supply of organic products and decreased prices for organic rice near future. There is a need to more greatly differentiate organic farming practices and products from those of no-chemical farming.

In order to get some basic datas on environmental friendly funtion against soil and water pollution and safe vegetable production by organic farming, chemical characteristics of soils cultivated by the conventional farming, greengouse cultivation and organic farming and acumulation of NO3--N in chinese cabbage and lettuce were analysed. The highest value of NO3--N in 0-30cm subsoil of organic farming was found among the 3 different farming systems, and it was 3.6 and 6.6 times higher than those of conventional farming in chinese cabbage and lettuce respectively. P2O5 also show high accumulation in the rhizosphere of organic farming compared to convnetional farming. The accumulation of NO3--N and P2O5 in the rhizosphere of organic farming were simial to those of greenhouse cultivation. The NO3- accumulation in chinese cabbage and lettuce by organic farming reach 3224ppm in chinese cabbage and 2543ppm in lettuce and it were 4.7 and 6.4 times higher than those of convnetional farming. It is urgently necessary to introduce the basic standard of IFOAM, EU and FAO/WHO Codex on organic agriculture into korean organic agriculture for operation of environmental friendly system and production of safe vegetable in terms of NO3-.

EFA production systems have through necessity resulted in the development of innovative practices for weed, pest and diseases control, for example, using ducks and snails for weed control in paddy fields. These practices began to be introduced in the early 1990's and the techniques have become more popular and have been adapted to suit regional conditions. In this study, the production practices, productivity and economic performances of organic and non-chemical rice farming adopting ducks and snails for weed control were compared. In the production practices, Korean organic and non-chemical farming seem to have several concerns in terms of sustainability. It comprises lack of resistant variety use and rotational cropping system as well as high dependency upon external inputs such as organic fertilizer and farming materials for pest control. The production level of organic farming is approximately similar level but 20% higher income than non-chemical farming, while, when it was compared with conventional farming organic farming showed 20% lower productivity but 20% higher income. Organic farming shows 15% to 18% higher profits than non-chemical farming as the snail-using organic farming tends to have higher income and lower input costs than duck-using organic farming. This may encourage more farmers to convert to organic production using these techniques than simply non-chemical farming in the future. This organic conversion could be more promoted by policy intervention. However, it may result in increased supply and therefore decreased prices for organic rice in the long term unless further market demand occurs. Balanced policy measures considering production as well as marketing and consumption are urgently required for the sustainable development of organic farming.

To investigate the technology trends in organic farming using patent analysis, total 1,026 patents in organic farming in Australia, EU, Japan, Korea and USA between 1974 and 2014 were analyzed. The number of the patents applied in organic farming was largest in Korea, followed by Japan and the USA. Since 2000, the patent application in Korea and USA increased drastically, while in Japan the patents in organic farming were applied steadily in the late 1980s. The applied patents in organic farming were mainly dominated in the field of organic production technology (AA) especially in Korea, while those in environmental assessment were merely applied. Most patent appliers were biased to private applier (80%) than national institutes including university. With this study, it is highly recommended that national interests and R&D on the organic farming fields are needed to meet the food safety.
