This study intends to review the sustainable agriculture and rural development concepts and practices and to present their directions toward better rural planning. Review of related literature including use of available documents and field visits both in Korea and overseas countries are two main methods of data collection with no quantitative analysis. Before sustainable (rural) development was fashionably used in the 1990s in the world, sustainable agriculture and other similar terminologies such as organic farming, alternative agriculture, low-input sustainable agriculture, natural farming, and environment-friendly farming are considered important in the academics as well as In action. The significant relationship between farmers' engagement in sustainable farming and their participation in voluntary social organizations is evidenced, so that it might be said that sustainable agriculture be the basis of sustainable rural development. Whether in sustainable agriculture or in sustainable rural development, the sustainable rural economy is considered more important toward better rural planning both in Korea and in the world.

Sustainable agriculture in Korea will gain important momentum by implementing The Direct Payment Scheme for Environmentally Friendly Agriculture in 1999. The farmers who want to participate in the program will be paid 530,000won/ha directly by the Government in return for engaging sustainable agriculture. The policy scheme which is a pilot program will be restricted to environmentally regulated areas to apply such as water supply protection zone, environmental protection districts and national parks. As a consequence of the policy, the supply of transitional organic agricultural products is expected to increase significantly. However the increased supply of low input agricultural products may have difficulties to find an appropriate marketing channel which is differentiated from the general agricultural product market. Development of an open market system for mass transaction of the low imput agricultural products is necessary. Also various government programs and projects which are designed for clean environment and regional community development must be integrated into the sustainable agriculture program to have synergy effects.

The question of how to establish sustainable agricultural systems has become as prominent as questions related to water, energy and climate change. High input/high output agriculture has brought with it many adverse effects; the massive deterioration of soil and water in both quantity and quality, increased greenhouse gas emissions and an increased prevalence of unsafe foods. Additionally, urbanization and climate change has worsened the shortage of farmland and reduced the supply of agricultural water. Given these challenges, maintaining, conserving and efficiently using agri-environmental resources, through fostering of sustainable agriculture, have emerged as key tasks in solving these problems. What is needed therefore is research, based on systematic and comprehensive empirical analyses, that can propose plans and methods for establishing an appropriate sustainable agricultural system. The empirical analysis of sustainable agricultural system is approached separately from economic, environmental and social aspects. An analysis of environment effect reveals that the available phosphate level is 1.3~2.1 times greater than the optimal amount in rice paddies, upland fields and orchards. Further examination has revealed that the excess nutrient is polluting both ground water and surface water. Analytical results for economic feasibility show that factors of production have been invested heavily in the rice crop. Under these conditions, sustainable agriculture, including low-input agriculture, appears to be a possible alternative that will facilitate simultaneous improvements in both economic feasibility and environment effects. Analysis results for sociality reveal that social factors include the value of producer, association and interior networks. Social conditions are comprised of leadership, consumers' awareness, education and conflict solutions. In addition, analysis as to the degree investments contribute to improving agricultural value added has revealed that the direct payment program is the most effective instrument. Experts confirm that economic feasibility can be improved by scientific and well-reasoned nutrient management on the basis of soil testing. Farmers pointed to 'economic factors' as being the largest obstacle to switching to the practice of sustainable agriculture. They also indicate 'uncertainty with regards to sustainable agriculture technology' as an impediment to practicing sustainable agriculture. Even so, farmers who believe environmental and regional issues to be the most pressing problems have expanded their practice of sustainable agriculture. The keys to establishing sustainable agriculture system are classified into the following four aspects. Firstly, from an economic aspect, the research indicates that agricultural policy needs to be integrated with environmental policy and that the function of market making based on the value chain needs to be revitalized. Secondly, from an environmental aspect, there is a need for an optimal resource management system to be established in the agricultural sector. In addition, sustainable agriculture practice will need to be extended with attendant environmentally-friendly and sustainable intensive technology also requiring further development. Thirdly, from a social aspect, green agriculture management needs to be fostered, technology and education extended, and social conflict mediated. Lastly, from a governance aspect, it will be necessary to strengthen good governance, assign and share suitable roles and responsibilities, build a cooperation system and utilize community supported agriculture.

A review on the technical development and agricultural policy direction for sustainable agriculture has been made to clarify the present conditions of agricultural environment for food production and natural resource conservation and to study prospects and solutions successfully to achieve food safety and environment conservation as the 21st agricultural paradigm. Although great improvement of environmentally sound and resource-conserving techniques, sustainability of Korean agriculture has been damaged by quantitative reduction and quality deterioration of agricultural land resources, insufficient implementation of low-input and organic matter recycling techniques and also improper cropping system. It is concluded that goal of sustainable agriculture can be successfully achieved by further improvement of environmentally friendly techniques, and stronger escalation of national implementation programmes with more financial supports including direct payments for sustainability of agriculture under systematical support and cooperation of AKS (agricultural knowledge system).

Emergy methodology was used to analyze the biophysical basis of Korean agriculture and assess its sustainablility. Total yearly emergy input into Korean agriculture was $7.72{\times}10^{22}sej/yr$ in 2013. Purchased inputs were the dominant emergy source, accounting for 90.1% ($6.95{\times}10^{22}sej/yr$) of the annual input. This clearly indicates that the Korean agriculture is a modern, industrialized system that depends mostly on market goods and services derived from nonrenewable resources. The monetary equivalent of the total emergy input was 18.9 trillion \/yr, 1.5 times greater than the total production cost from farm expense surveys. Emergy return on investment of Korean agriculture was low, with an emergy yield ratio of 1.11. Korean agriculture appears to exert pressure on the environment as revealed by the high environmental loading ratio of 9.30. With very low emergy input from renewable sources (9.7%) and high environmental pressure, Korean agriculture is not sustainable, with an emergy sustainability index of 0.12. This study suggests that higher use efficiency of and lower dependence on nonrenewable purchased inputs need to be prioritized in an effort to enhance the sustainability of Korean agriculture.

The duck-rice forming system is increasingly spread up throughout Korea since 1992. It is discussed the rice field, rice quality, weed and pest management in the duck-rice weeding system compared to conventional farming system. Moreover the optimizing duck population, system management and fertilizer application rate were reported. Energy input and output by duck-rice farming system were carefully compared with those of low input sustainable paddy field and conventional farming paddy field. To find out the environmentally sound function of duck-rice system, the total nitrogen in paddy soil and paddy water, and nitrogen cycle in paddy rice cultivation system were analysed. finally the input and output were calculated, and ecological characteristic were determined in terms of nitrogen balance, labor input, animal input, renewable energy input, turnover of soil organic matter, energy loss, non-renewable indirect and direct energy input. It was concluded duck-rice weeding system could be recommended in terms of net only environmentally sound, but also farmer's income. But there are still some research needs for successful adaption of duck-rice farming to investigate to determine the optimal population of duck in rice paddy field unit, release time of duckling, duck management after release, and strategy for duck marketing and duck processing.

As the conventional farming emphasizes the productivity and the quantity produced, large amount of agricultural chemicals have been used. As a result, natural environment and human health are critical issues in recent years in Korea. Reflecting these problems, many farmers have begun to practice the LISA(low input sustainable agriculture) voluntarily across the country. In this study, a survey was made to 13 apple producers who have been producing the fruits by practicing the LISA, and wanted to analyze the production and marketing information in order to suggest the improvement strategies for the sustainable agriculture. Some of the improvement strategies were suggested as follows ; First, advance payment to the LISA apple growers should be supplied in order to make it easier for the financially burdened producers. Also, some kind of means should be developed to prepare the equipments/machineries to make the organic fertilizers. Price differentiation should be utilized in marketing the products, and mass marketing channels for the LISA products should be provided for them. Public quality guaranty is badly needed in order to accelerate the marketing. Finally, stronger producer organizations should be organized and subsidized by the government because those organizations are playing an important role in developing the LISA.

A relatively wide range of weed technology concerning sound herbicide development, its formulation exploitation, and application techniques was extensively reviewed in accordance with least inputted sustainable agriculture. Herbicide plays an integral part of farmers' cultural practices in Korean agriculture like rest of world over. Weeds are more obstacle to the adaptation of more sustainable agriculture system. Because weeds dictate most of the crop production practices, weed scientists must become the leaders of collaborative integrated approaches to agriculture systems research. Feasible ways to minimize herbicide input involve the positive introduction of low-rate selective chemistries, innovative formulations, biological herbicides and newly developed application technology. Since herbicide will remain to be a core position in weed management for the foreseeable future, research is needed to optimize herbicide application technology and to minimize their impact on the environment. Public concerns and regulatory pressures on agricultural chemicals are likely to strengthen throughout this decade and coming. Researchers, pesticide manufacturing industries and regulatory authorities have to work together more closely, leading to understand each other better, as well as the needs of our customers and those of society. To be taken extensively, weed control management practices in the future have to be accepted such a way the respective demands of environment, society and economics are entirely matched.

There has been an increasing public concern about environmental safety and human health of field crops while customer consumes more and more field crops, to which overdose and residual chemicals were applied. As a solution for the problems, construction of sustainable agroecosystem is spreading out to pursuit the economic value of agricultural management as well as to meet environment concern. Public has extended their understanding on the preservation of environment and safeness of agricultural products, and governmental policy toward sustainable agriculture drives rapid increase of the production of sustainable agricultural products. Under this circumstances, it is time to encourage more consumption and to activate market system for the sustainable agricultural products. This study was initiated to diagnose the problems and future direction of domestic sustainable agriculture by analyzing the overall opinions of consumer on the sustainable agriculture. The results are as follows: The pursuit of low input management is a prerequisite to creat high valued agricultural products, and serious consideration should be taken to produce clean crops using natural products. Consummers are willing to pay 10∼50% more prices if the products get certified by official eco-label programs. It is believed that practice of sustainable agriculture using biopesticide and natural pesticide would accelerate the rapid extension of this pro-environmental agricultural management. To activate production and consumption of sustainable agricultural products correct informations on safety should be addressed to customer, and confidence has to be brought about from customer. This could be done by obtaining various and efficient distribution route, product competency for quality, upgraded sales strategy, maximum utilization of certificate system, and practice of recall system, so on.
