        This research evaluated the environmental impact of waste film used in the farming industry which is subject to voluntary agreement by Waste Charge System using Life Cycle Assessment (LCA). When analyzing the environmental scores applying weighted values, production of raw materials, production of goods and disposal had nearly 73%, 15% and 11% of contribution to the environmental impact and also, amongst impact categories, resource depletion and global warming had 63% and 32% of contribution respectively. For resource depletion which had the highest contribution, production of raw materials, production of goods and disposal occupied around 86%, 9% and 4% of it, and the impact category of resource depletion that belongs to production of raw materials, accounted for about 54% of the whole environmental score. Here, over 95% of it was caused by crude oil. When investigating the contribution of each phase to global warming that is the key issue of low carbon green growth, production of raw materials, production of goods and disposal had respectively, 45%, 28% and 27% of contribution. As the result, production of goods and disposal had higher contributions than resource depletion. The entire contribution of production of goods and disposal to global warming was about 17%, and it is predicted that it would bring a huge impact, considering the possibility of establishing improvement plans. In the production of goods, electricity consumed was the main cause of global warming, and electricity used in the recycling process and incineration occupied approximately 52% and 42% of the disposal stage. In conclusion, we should pay attention to energy used in the production of goods and recycling for improving an environmental competitiveness of goods, and reduction of energy would be able to satisfy economic feasibility and environmental efficiency of the whole process of agricultural PE film.

        최근 농업용저수지를 포함한 농촌지역 하천의 친수활동이 증가하면서 농촌수계의 경관, 수질 및 생태보전 등 환경에 대한 관심이 고조되고 있고, 이로 인해 농촌지역 용수수요 다변화와 물 부족 심화현상 등을 해결할 수 있는 수자원 개발의 필요성이 증대되고 있다. 이러한 측면에서 4대강 살리기 사업의 일환으로 추진되는 농업용저수지 둑높이기 사업은 추가로 필요한 농업용수뿐만 아니라 하천 수질개선을 위한 하천유지용수 확보를 위해 필요한 사업임에도 불구하고 운영계획 및 운영방안이 명확하지 않은 실정이다. 따라서 본 연구는 낙동강의 특정 소유역을 대상으로 농업용저수지 둑높이기 사업을 통해 확보할 수 있는 추가 저수량을 검토하였고 저수지 운영방안에 따라 하천유지용수로 방류할 경우 하류하천 수질개선효과를 평가하고자 하였다. 저수지 운영시나리오에 따른 추가적인 물공급량 확보는 하류하천 수량과 수질에 영향을 줄 것으로 예측되었으며 유량은 1∼8%의 증가효과와 2∼10%의 수질개선효과를 나타냈다. 특히, 저수지 운영상 2월에서 4월 사이에 추가로 방류를 실시할 수 있으며, 하천의 수량 및 수질 개선에 효과적인 것으로 나타났다. 그러나 농업용저수지의 수질은 지류하천뿐만 아니라 낙동강 본류 수질에 큰 영향을 미칠 수 있기 때문에 저수지 수질개선 및 관리가 중요할 것으로 판단된다.

        The purpose of the present study is to construct a rural development strategy from the nexus between spatial changes in specialized crops and suitable cultivation area of the crops. This paper pays particular attention to identify product life cycle of specialized crops in rural areas and estimate the impact of climate change on alterations in spatial distribution of the crops. In order to do so, first of all, this study applies multi-level model (Random coefficient model) to estimate the regional coefficient of five orchard crops. It utilizes the data 1995 to 2010 Korea Agricultural Census. Futhermore, it also adopts overlay analysis by ArcGIS to identify the development path of the crops and the relationship with climate change. Based on the results, it suggests a mechanism activating regional agriculture. The findings propose re-searching and relocating specialized regions of the crops. Especially, it proves each rural area can drive the new agricultural strategy to strengthen regional agriculture by estimating the relationship between development of specialized crops and suitable cultivation areas. For instance, shifting specialized crops in particular regions and enriching genetic or species varieties can be primary measures and it will contribute to improve the reliable base for income sources in the rural communities. This paper also offers specific policy implications regarding rural development plans in response to crops' life cycle and climate changes.

        Agricultural income is calculated with producer price, output and management cost. This study compared organic farming with conventional one for agricultural income, producer price and output by items. And then it proposed the method of item selection and crop system from a diversification point of view. The coefficient of variation to producer prices in organic farming was 4.7%, and conventional one was 30.3% because organic products have been produced in a system of contract farming with consumers’" cooperative. This result means the price of organic products is stabler than that of conventional price. And agricultural income of organic farming has been generally known more than that of conventional one. However, agricultural gross income of conventional farming was more than that of organic one by 20.3% in 2010. It was caused by output reduction of a few items(fer example; onion, large green onion, potato and young pumpkin) due to freak weather conditions and constant producer price for several years in organic farming. In order to increase agricultural income, appropriate crop selection and system should be introduced to organic farming. A principal crop is the rice plant and 2 subordinate crops are dry crops at bare field and greenhouse respectively. Thus 5 crop systems that agricultural gross income are relatively increased larger among 15 crop systems estimated are rice+ginger+cucumber, rice+ginger+tomato, rice+large green onion+cucumber, rice+sweet potato+cucumber and rice+onion+ cucumber.

        Urban parks are progressing but are in chaos in the twenty-first century. Therefore the purposes of this study are to consider critically and classify the new paradigm of urban parks. Urban parks are one of the space products, and progressing aspects can be divided into three parts; supply, demand and market aspects. In the abstract, urban parks' progress represents process, openness or voidness, general and cultural ecology, productivity, experience program, identity or sense of place, carriers of urban regeneration, urban infrastructure, community space, multi-layered activity, active space, communication with urban space, tool of low carbon strategy and consilience. But urban parks have come under increased criticism about the long period development on trees growth, covering open space, limitation of general and cultural ecology, production, activity programs, identity and community space, visible urban regeneration, economic validity, urban sprawl, not using as the low carbon strategy, and finally negative consilience with contiguous fields. We collected these critical consideration about progressing urban parks, and proposed urban agricultural park as one of the alternative urban parks. This is closely connected with sustainable region development, low-carbon society, local food, well-being, Lohas paradigm and amenity of urban life.

        In this study, the assessment of livestock manure nitrogen loading for recycling farming in Yeoju-Gun carried out comparing manure units based on the cultivation areas and the N-amount of manure that are generated from livestock manure. Manure units (MU) are used in the permitting, registration, because they allow equal standards for all animals based on manure nutrient production. An MU is calculated by multiplying the number of animals by manure unit factor for the specific type of animal. The manure unit factor for MU determination was determined by dividing amounts of manure N produced 80kg N/year. In this study, manure unit by nitrogen concentration and amount of animal manure was calculated as follows: Hanwoo multiplied by 0.36, dairy cows multiplied by 0.8. swine multiplied by 0.105. The laying hens and broilers multiplied by 0.0079, 0.0049, respectively. The analysis of liquid manure unit per ha shows that the N loading by LMU is quite different by region. When it comes to nitrogen loading, the LMU per ha of cultivated land in excess of the N-amount was the highest in the Bukne-myeon province with 2.76 MU/ha, which is higher than the appropriate level. The Ganam-myeon province came next with 2.53 LMU. To be utilized as a valid program to build the environmentally friendly agricultural system, diverse measures shall be mapped out to properly determine manure units, evaluate N-loading and to properly manage their nutrient balance of each region.

        This study was conducted field surveys and theoretical discussion whether small farmers thinks there are economics of scope in small organically grown crops-livestock farming cycling system. The discussions are summarized as follows. At the end of October 2011, the cycling agriculture farms are only a total of 15 farmers, 0.1% of total organic farms in Korea. The FMD disease, FTA, family farm structure, the importance of animal health and welfare, agricultural cycles, when considering the valuation of the multifunctionality, alternative agriculture is small farming cycling system. Organic agriculture is a ‘cooperation-cycling-family farm’ in the interaction it is important to understand. The two groups were surveyed. Group 1 is 6 farmers who practicing cycling fanning system, and Group 2 is the 33 farmers who wish to cycling fanning system. Interview survey and the survey results was obtained as follows. First, We find that there are strong economies of scope, due to a decreased costs have increased net profit. Second, the multi functional values is realized also cycling farming system. Third, but some certification standards leads to high transaction cost. Thus, a small family farm who wishing to target organic livestock certification standards need to improve.
