The purpose of this study is to evaluate farmer's general contents on the current direct payment schemes and to derive some improvement measures, based on the survey data for the three types of direct payment schemes currently executed in Korea; Rice Farmer's Income Support, Early Retirement Aged Farmer's Support and Less Favored Area Direct Payment. In recent years we have introduced diverse direct payment schemes that are expected to have immediate effects in a short term period without enough preparation of the policy, which raises some contradiction between the agricultural policy and the original purpose of the direct payments. The result shows some important revisions should be made related the direct payment schemes, such as farmer's income stability through the improvement of unit payment and the payment length jointed with criteria of the payment, in addition to keeping up multifunctionality of agriculture and enhancing the effect of structural adjustment in agriculture.

Arbuscular mycorrhizal fungi (AMF) are widespread soil endophytic fungi, forming mutualistic relationships with the vast majority of land plants. Biochar (BC) has been reported to improve soil fertility and promote plant growth. However, limited studies are available concerning the combined effects of AMF and BC on soil community structure and plant growth. In this work, a pot experiment was designed to investigate the effects of AMF and BC on the rhizosphere microbial community of Allium fistulosum L. Using Illumina high-throughput sequencing, we showed that inoculation of AMF and BC had a significant impact on soil microbial community composition, diversity, and versatility. Increases were observed in both plant growth (the plant height by 8.6%, shoot fresh weight by 12.1%) and root morphological traits (average diameter by 20.5%). The phylogenetic tree also showed differences in the fungal community composition in A. fistulosum. In addition, Linear discriminant analysis (LDA) effect size (LEfSe) analysis revealed that 16 biomarkers were detected in the control (CK) and AMF treatment, while only 3 were detected in the AMF + BC treatment. Molecular ecological network analysis showed that the AMF + BC treatment group had a more complex network of fungal communities, as evidenced by higher average connectivity. The functional composition spectrum showed significant differences in the functional distribution of soil microbial communities among different fungal genera. The structural equation model (SEM) confirmed that AMF could improve the microbial multifunctionality by regulating the rhizosphere fungal diversity and soil properties. Our findings provide new information on the effects of AMF and biochar on plants and soil microbial communities.

도시화로 인하여 농경지가 기속적으로 줄어듦에 따라 농업의 환경적 공익기능도 축소되고 있다. 따라서 농업의 공익기능 관련 실증 분석사례를 제공함으로써 식량안보 및 공업의 공익기능을 유지하고 농지보전 정책 논리를 제공하고자, 용인시를 대상으로 토지이용도를 이용한 연차별 농경치 이용면적과 변화를 분석하고 지표면 온도 추정을 통하여 환경보전 기능을 평가하였다. 최근 10년간 도시화가 현저히 진행된 용인시를 대상으로 세부정밀토양도에 기반한 1999년 토지이용 현황과 위성영상에서 추출한 농경지 지도와 지적도에 기반한 2006년의 농경지를 중심으로 한 토지이용 현황을 비교해 보면 논, 밭, 과수원 등 농경지와 산림의 분포가 현저히 감소한 반면, 주거 도심지의 면적이 크게 확대된 것으로 나타났다. 특히 처인구에서 농경지 감소와 도심지 확장 현상이 눈에 띄게 나타났다. 토지이용 면적 및 지목별 변화를 보면 1999년 용인시 토지이용 면적은 산림 > 논 > 밭 > 주거 도심지 순으로 나타났으나 2006년의 토지이용 면적은 산림 > 주거 도심지 > 논 > 밭 순으로 바뀌었다. 논과 밭의 면적은 1999년에 비해 2006년에 각각 34%와 41%, 감소하였고, 주거 도심지 면적은 245% 증가하였다. 논이 주거 도심지로 전용된 면적이 1,751.1 ha이며, 밭이 주거.도심지로 전용된 면적이 1,242.1 ha로 나타나 전용된 면적의 가장 많은 부분을 차지하는 것으로 나타났다. 용인시의 농경지 면적 변화에 따른 농업의 환경적 기능변화에 대하여 계량화한 결과는 논 면적이 1999년에 8,063.3 ha에서 2006년에 5,309.3 ha로 감소한 결과, 농경지의 환경적 공익기능이 34% 감소한 것으로 나타났다. 마찬가지로 밭 면적이 1999년에 3,572.1 ha에서 2006년 2,112.5 ha로 줄어듦에 따라 환경적 공익기능이 41% 감소된 것으로 나타났나. Landsat TM 열상의 열 적외광을 이용하여 용인시의 두시기별 지표면 온도 분포를 비교 분석하였다. 1994년 9월에는 $20^{\circ}C$ 이하가 대부분이었으나, 농경지 및 산림 감소와 도시 확장 이후인 2006년 9월에는 $25^{\circ}C$ 이상 되는 지역의 면적이 현저히 넓게 분포하는 것으로 변화하였다. 시기별 토지이용별 지표면 온도분포 비교를 하였을 때 1994년 9월 지표면 온도 영상에서 $25^{\circ}C$ 이상인 지역은 전체 면적의 0.3%로 나타났고, 2006년 9월은 11.2%로 넓게 분포하는 것으로 나타났다. 2006년 9월에 지표면 온도가 $25^{\circ}C$ 이상 되는 지역에 분포하는 주거.도심지의 면적이 37.7%로 가장 높게 나타났으며, 논과 산림의 분포면적 비율이 각각 5.6%와 4%로 나타났다. 위의 결과로 여름철 고온기에 논과 산림이 주변의 지표면 온도를 낮춰주는 기후순화 기능이 크다는 것으로 추정할 수 있었다.

The aim of this review is to show the evolution of the dairy goat sector in Europe from all perspectives. Starting from the current situation, the challenges and future potential of this livestock system are presented, as well as strategies to overcome the difficulties faced. Europe holds 1.9% of the world goat population and produces 15.1% of goat milk recorded worldwide. The goat species plays a fundamental economic, social and environmental role in many regions of Europe. The wide diversity of production systems and autochthonous breeds makes the sector very heterogeneous. In order to improve viability, a number of strategies need to be adopted to solve the current problems such as a low profitability, absence of generational change and a little or no recognition of the social and environmental role of the sector. Some strategies to improve the situation of the European goat sector include: i) generating market value that will recognise the diversity of the dairy goat sector (breeds, feeding models, derived products${\ldots}$); ii) promoting and raising awareness of the functional attributes of goat milk and derived products so as to increase consumption; iii) assigning an economic value to environmental and social functions; iv) improving working conditions through technological innovation to make goat farming more attractive to young people; and v) processing more milk into cheese or other dairy products in production areas.

The study aims to draw out implications regarding systematic reservoir management through analyzing the reservoir conservation activities and policies in Hyogo Prefecture which has the most agricultural reservoirs in Japan and similar agricultural form to that of Korea. The results are as follows. First, it turns out that consistency in policies and persistent drive are key to success. Since the late 1990s, the Hyogo Prefectural government has expanded the reservoir conservation policies, consistently trying to ellicit the multifunctionality of reservoir, and also has shown persistent drive toward the conservation policies through systematic process. Second, it is clear that the Prefectural government has shown a great degree of activeness. It established ordinances before acts were legislated by the central government. In addition, the Hyogo Prefectural government ran a supportive organization with its own funds. Third, the establishment of systematic enforcement system played a critical role. The efficiency in the policy enforcement derived from the dual conferences, Prefectural-level conference dealing with the related policies throughout the Prefecture, and local-level conference discussing policies based on regional characteristics.

In order to evaluation of beneficial functions for organic farming, we have divided beneficial functions as 9 sub-functions such as flooding control, fostering water resources, purifying the air, mitigating summer climate, purifying water quality, decreasing soil erosion, accumulating soil carbon, conserving biodiversity, and preventing accidents from pesticides. And they were quantified by searching related repots and statistics, and surveying fields. Organic farming, especially organic paddy farming, showed that some functions like fostering water resources, accumulating soil carbon, conserving biodiversity, and preventing accidents from pesticides were higher than conventional paddy farming, while the others were almost similar. The fostering water resources function was evaluated as 4,297 ton $ha^{-1}\;year^{-1}$ to increase about 3.6% comparing with that of conventional farming. New function for accumulating soil carbon at organic paddy fields has been assessed by 4.67 ton $ha^{-1}$ in terms of long periods over 10 years. Considering area of organic paddy farming in Korea and value of carbon price, it was evaluated monetary value as 22.4 to 84.1 billion won using replaced method. It could be also evaluated that flooding control, fostering water resources, purifying the air, mitigating summer climate, purifying water quality, decreasing soil erosion, and preventing accidents from pesticides were 2,980, 123.4, 482.6, 87.5, 0.9, 55.6, and 284.1 billion won, respectively. Conserving biodiversity function would be very big at organic farming though it couldn't be evaluated as monetary value.

This study was conducted field surveys and theoretical discussion whether small farmers thinks there are economics of scope in small organically grown cropslivestock 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 farming system, and Group 2 is the 33 farmers who wish to cycling farming 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 multifunctional 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.

The elements that determine the success of development projects on goats and the prerequisites for ensuring this are discussed in the context of the bewildering diversity of goat genetic resources, production systems, multifunctionality, and opportunities for responding to constraints for productivity enhancement. Key determinants for the success of pro-poor projects are the imperatives of realistic project design, resolution of priorities and positive impacts to increase investments and spur agricultural growth, and appropriate policy. Throughout the developing world, there exist 97% of the total world population of 921 million goats across all agroecological zones (AEZs), including 570 breeds and 64% share of the breeds. They occupy a very important biological and socioeconomic niche in farming systems making significant multifunctional contributions especially to food, nutrition and financial security, stability of farm households, and survival of the poor in the rural areas. Definitions are given of successful and failed projects. The analyses highlighted in successful projects the value of strong participatory efforts with farmers and climate change. Climate change effects on goats are inevitable and are mediated through heat stress, type of AEZ, water availability, quantity and quality of the available feed resources and type of production system. Within the prevailing production systems, improved integrated tree crops - ruminant systems are underestimated and are an important pathway to enhance C sequestration. Key development strategies and opportunities for research and development (R and D) are enormous, and include inter alia defining a policy framework, resolution of priority constraints using systems perspectives and community-based participatory activities, application of yield-enhancing technologies, intensification, scaling up, and impacts. The priority for development concerns the rainfed areas with large concentrations of ruminants in which goats, with a capacity to cope with heat tolerance, can be the entry point for development. Networks and networking are very important for the diffusion of information and can add value to R and D. Well formulated projects with clear priority setting and participatory R and D ensure success and the realisation of food security, improved livelihoods and self-reliance in the future.
