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.

This study attempts to make an observation on the problems and prospects for overseas agricultural investment(OAI) through the insights of farming and farmed companies abroad and through secondary data. OAI mainly aims at the securing steady supplies of crops, which could be anticipated to have increased foreign dependence, and to prepare for crop price fluctuations in the international markets. These functions of OAT are classified with the public and private sector. The public sector needs are largely crops supply for national food consumption and bilateral collaboration between nations. The private sector needs are to gain maximum profits from agricultural investments and to produce raw material for self-consumption in overseas farming companies. The problems in OAI are legal and institutional restrictions in the project area or nation; generally economical unfeasibility in the farm projects, and technical limitations of the farming companies. The prospects of OAI are not very promising. The reason why those many companies which previously planned on OAI changed their investment plans after what is called IMF system with financing difficulties.

This study aimed at examining the investment and economic analysis of greenhouse horticultural project area by governmental subsidy project. There were only 5 project areas that economic efficiency of investment is recognized in 30 project area in Kyungsangnam-do. And there are 7 project areas to gain farm firm revenue. These were possible area to develop to farm firm. There are 4 project areas to gain farm firm revenue in 18 project areas of glass greenhouse area, and 8 project areas to gain farm firm revenue in 12 project areas-vinyl greenhouse area. The rate of return of the fixed capital is higher in the vinyl greenhouse area than in the glass greenhouse area by type of greenhouse. There were cultivated tomatoes, cucumbers, peppers, etc. in the greenhouse area. The investment efficiency of the fixed capital is higher in cucumber and pepper than in other vegetables. Flowers a re lower than the vegetable in investment efficiency.

The structure of the Hanwoo (Korean Native Cattle) Industry remains very weak and vulnerable to the WTO/IMF system. Considering that the majority of cattle farmers are small sized, and that marketing systems are outdated and inefficient, rapid expansion of lower priced beef imports by WTO system and rapid increasing of production costs by IMF system would lead to the deprivation of a regular source of farm income and threaten the stability of rural life. Accordingly, the Hanwoo industry should be expanded in accordance with progress in the implementation of (1) programs for the structural adjustment and (2) measures to compensate for the loss. Efforts for lowering major production factor costs needs to continue, In order to increase the supply of calves at low cost, the programs of collective cow-calf farms should be expanded, thereby reducing the cost of calf purchase, which constitutes the largest share of Hanwoo production cost. Also, feedlot operations should be encouraged for small herd farms in order to achieve a substantial saving in beef production costs by integrated operations from calf production to cattle fattening. A substantial saving would also be made by collective purchase and distribution of various inputs through the cooperatives' channels. Extension services should be strengthened for cattle farm management, cattle care and feeding, prevention of cattle disease, etc. In order to minimize cash outlays for commercial mixed feeds, utilization of far by-products as feeds should be enhanced and production of forage crops productive of resources, such as land and rural labor, during the farm o(f-season, needs to be encouraged. Also, technological development for enhancing the nutritional value of farm by-products should be encouraged. Measures for successful segregation of the Hanwoo beef market should be implemented, thereby enhancing incentive for quality beef producers and protecting consumers willing to pay higher price for quality beef. For development of the Hanwoo industry, a considerable time frame would be required in order for (1) small livestock farmers to make a successful adjustment by staying in the enterprise and achieving increased price efficiency (2) livestock farmers to acquire know-how for producing quality Hanwoo beef, (3) the ongoing Government policy of enhancing price-quality competitiveness, and for improving the quality Hanwoo beef marketing to take root. (4) consumers to increase their ability to distinguish meat quality, and others.

The Food Problem of North Korea is well known to all of us. And we, South-Koreans, are oblidged to solve the food problem of North Korea because we should prepare and cope with the reunification of Korean Penninsula in the near future. Although many organizations of the UN (including Korea) are engaged in food-support to North Korea from the humanitarian viewpoint, a great many people are disclosed to the starvation for the food deficiency. Now how to solve the food problem of North Korea? It is the agro-cooperation between South and North Korea. The most realistic method among them is the agro-cultivation in contract.

The objectives of this article are to identify the current status of agricultural infrastructure in North Korea and to suggest some cooperation measures among South and North Koreas and international agencies in order to develop the North Korea's agricultural infrastructure. The area of cultivated land in North Korea is 1,992 thousand ha (paddy field: 585 thousand ha: upland: 1,407 thousand ha) in 1997. Major water use facilities in North Korea are 1,900 reservoirs (included 100 big dams), 36,400 irrigation pumping stations, 1,600 drainage pumping stations, and 14'a,000 wells. In addition, there is 'two thousand Ri canal construction project' linking the rivers of Aprok, Daeryong, Daedong, Jaeryong, and Yesong. The unit of paddy land consolidation is about 1 ha which is regarded as rational for agricultural mechanization. The project of 'Darak' upland construction to create small size farmland, which has been carried out since 1976 has been unsuccessful due to the shortage of construction equipment. The area of farmland created by reclamation by 1995 is only 75 thousand ha although the potential project area is at)out 320 thousand ha along the western coast. It is due to the fact that civil engineering technologies and equipments are old and investment funds are insufficient. These are a few suggested areas of cooperation among South and North Korea and international agencies in order to improve North Korea's agricultural infrastructure : i) see land reclamation and land consolidation projects to increase paddy fields for rice production; ii) rehabilitation project in farm land areas devastated by flood; and iii) agricultural water development project which including diagnosing and rehabilitating irrigation and drainage facilities.

Assuming the united Korea, total population is estimated to be 70 million and grain demand for the people is estimated to reach 30 million metric tons. Cultivated land in North Korea is about the same as South Korea i.e. 2 million hectares. However grain production in North Korea is about one half of South Korea's, 6 million metric tons in the South and 3 million metric tons in the North a year. This implies that the United Korea need to import more than 20 million metric tons of grain a year and it will trigger many economic and social problems for the United Korea. In order to meet deficient grain supply, the United Korea can choose three possible policy options; importation of grains or increased investment in foreign agricultural development or increase in domestic supply Among the possible policy options, increase in domestic supply is desirable and can be achieved by developing North Korea's grain supply potential. North Korean agricultural development can also be achieved most effectively through cooperation between the South and North. An effective policy option for agricultural cooperation between the South and North is supply of agricultural inputs such as fertilizer and pesticides and exchanges of agricultural technology. Cooperation between the South and North in the agricultural sector should be achieved and developed further to solve the potential food problem before unification.

The Northeast district includes He Longjiang, Liaojiang and JiLin province, which has an abundance of in vast, fertile, arable lands, and natural and human resources. So the Northeast district can provide the most beneficial conditions for the agricultural production and development to China. Korea is near the Northeast district, and its agricultural technologies are advanced. So it is advantageous and mutually beneficial to have cooperation between China and Korea. This article explores social structure, natural situation, present situation of agriculture and livestock, population and incomes of the countryside of the Northeast district. At the same time, this article introduces and promotes a program of cooperation between China and Korea in agriculture and livestock.

Food resources have been supplied more and more by crop land expansion, technological Improvement for higher crop yield, establishment of irrigation system, and input of fertilizers, chemicals and others, to sustain a world population increase currently about 6 billion. Food demand will be significantly increased in the 21st century due to population increases of 90 million per year and more consumption of meat with per capital income increase. But food production increase will be limited by difficulty of crop/irrigation land expansion and small or decreasing effectiveness of fertilizer use. Development of new techniques for higher yield per ha is only one way to meet future food demand increase. Optimistic prospect for food demand/supply balance was reported by FAO until 2010, and IFPRI until 2020. However, Worldwatch Institute warned world food supply will be less than expected demand by 500 million tons of cereal grains in 2030. It is necessary to establish a national plan to meet expected worldwide shortage of food resources in 21 century. What planning should be under taken to meet the upcoming century of food shortage in Korea whose food self-sufficiency rate is only $30{\%}$. It is recommended that (1) keep paddy field area as much as 1,100 thousand ha, (2) expansion of barley and wheat cultivation on all paddy area in winter season, (3) continue development of new technology to get international superiority of food resources produced in Korea, (4) expand nationwide the importance of food security under the current financial crisis encountered In Korea, and for food security in the future unified Korean peninsula.

Tong-il, the high-yielding rice variety bred on early 1970, effected a turning point in modern rice production in Korea. As rice production reached the highest record yield in 1978 with HYV, Korea achieved self-sufficiency in domestic supply of rice (or the first time in (her own) history, HYV required high input of fertilizers and pesticides for proving its yielding ability and needed new techniques such as early nursery-planting to prevent chilling damage. But, farm economy did not follow the successful achievement of rice production because of increased farming cost and inflation.'Tong-il variety has been replaced by new high-yielding Japonica varieties from 1980 when record-low-temperature during summer months had persisted. Also, the cooked rice of Tong-il variety did not agree with the appetite of Korean people. Though the hectarage of Tong-il rice did reduce, farmers applied the same high-input cultural techniques for new Japonica cultivars as did for Tong-il variety. Heavy application of nitrogen fertilizer contaminated surface and ground water with nitrate ions while phosphorous fertilizer was blamed for algae pollution. Frequent spray of pesticide and herbicide reduced significantly the biotic population in paddy ecosystems including insects and soil microorganisms. The new technologies of the 21st century must be directed to produce safe food, to save natural resources, and to preserve a clean environment for human welfare. We need low-input sustainable farming techniques to provide high-yielding crops and to preserve a healthy ecosystem.

Food Self-sufficiency rate in Korea was 26.4 percent in 1996. It include $89.9{\%}$ for rice, $99.6{\%}$ for root and tuber crops, and $73.5{\%}$ for barley. To make things worse, self-sufficiency for wheat and corn were far less than 1 percent. As food is considered as weapon, every effort should be given to increase the self-sufficiency. In order to cope with expected food crisis, we suggest wheat and barley be grown in winter period, where there is climate fit. The aim of this paper is to survey systematically the status of food supply and demand of wheat and barley and to encourage farmers make double cropping systems with better stability in yield and economic return.

The yearly consumption of soybean ranged from 1.5 to 1.7 million tons in Korea during 1995-1997 with an increasing trend of annual consumption by 60,000 tons. Gross consumption of soybean was 1.74 million tons in 1997: 1.292 million tons for feed, 0.433 million tons for food and its processing, and 15,000 tons for seed and other uses. Particularly, Korea totally depends upon imports of soybean for feed and oil. Only about $40{\%}$ of soybeans used for food and its processing are supplied through domestic production. Korean markets will be open to foreign agricultural products except for rice in 2004 when the Uruguay Round treaty is completed. According to the Korean Rural Economics Institutes reports, soybean consumption in 2004 is expected to be 1.87 million tons that is higher than that in 1997 by 0.13 million tons. In order to meet the need for soybean, Korean government planned to supply from 0.17 million tons of domestic production plus 1.7 million tons of imports, and also planned to raise the self-supply rate of $9.1{\%}$ in 2004 from $8.6{\%}$ in 1997. According to the USDA reports on international soybean production and consumption, its production is expected to be 150 million tons over the world and the international market prices for soybean will be unstable in 2004. Based on these reports, international soybean trade capacity will be 36 million tons in 2004 that is lower than 39 million tons (accounting for $25{\%}$ of gross production) in 1597. Also, a term-end stock in 2004 is estimated to be 9.6 million tons that is low as compared to 18.6 million tons In 1997, In coping with domestic and international soybean production, consumption and supply, and further possible food crisis, national policies and continuous efforts are necessarily required to promote domestic production and to reduce imports of soybean.

Environmental conditions and expected profit are the major criteria to select crops to be cultivated in any region. Traditionally, miscellaneous crops have been cultivated as alternative crop in case of unfavorable climate or supplementary crop in marginal lands. Since the successful breeding of high yielding varieties of staple crops and development of cultural techniques in 1970s in Korea, production of miscellaneous crops decreased markedly due to the rapid commercialization of agriculture and increased productions of horticultural crops, although yields have been doubled during the last $2\~3$ decades. On the other hand, animal husbandry has been developing remarkably parallel with national economic development and the increased consumption of animal products. As a result, imports of feed grains such as corn have increased rapidly, while roughage production became lower than demand. Among miscellaneous crops, corn production increased markedly through the development of hybrids and due to its importance as silage crops. Acreage of corn production including grains, fresh corns and feeding is about 120,000 ha, while acreage of buckwheat is about 5,000 ha and those of other miscellaneous crops decreased to a level of about 1,000 ha. Although miscellaneous crops have low yield potential and are unprofitable due to low price and imports of cheap foreign products, they should be kept to cultivate. Miscellaneous crops are important components that maintain diversity among upland crops as well as alternative crops in case of unfavorable climate. The low yield potential of miscellaneous crops might be due to lack of efforts to breed high yielding varieties and to develope cultural techniques. Continuous investment in research, exploitation of new utilization for miscellaneous crops as sustainable crop, honey crop and sightseeing crop, and development of healthy and special foods will promote their cultivation. Animal feeding in Korea depends mainly on formula feeds. As the number of animals increases to meet demand of animal products, there is no alternative way but to import grains to feed them. But roughage production, which is necessary for normal growth of ruminant animals, should be increased. However, lack of arable land and pasture land limits the production of good roughages. It is estimated that number of course for meat and milk production will be $2.5{\~}2.6$ million and total of $6.2{\~}7.5$ million tons of roughages should be produced. This implies that more than 1 million tons of roughage are needed, although pasture land, upland for forage crops, forage crops after rice cultivation and rice straw are utilized. Therefore, new reclamation of pasture land, increased roughage production in cultivating land, increased cultivation of forage crops after rice, more utilization of rice straw and active exploration of indigenous plant species as roughage resources should be promoted

In Korea, chemical fertilizers and agricultural chemicals have had a significant impact on food production and these are today thought to be an indispensable part of modern agriculture. On the other hand, socioeconomical and IMF and WTO status in Korea are constant reminders of the vulnerability of our fossil fuel dependent agriculture. A new crop production system to improve economic, environmental and production efficiency must be exploited. Our particular concern has been given to an integrated cropping system involving recycling of crop residues, soil and N management, biological N fixation and multipurpose legumes. As a new integrated crop production system, a no-till direct-sown rice-vetch relaying cropping system has been proposed in this paper. The formulation of this system is based on the conception that N fertilizers being neither limitlessly available nor affordable, the current high-input crop production systems have produced troubled results severe labour shortage ill rural areas, balance of payment, environmental degradation and reduction of human health far exceed economic concerns. A natural and logical consequence is that long-term sustainability of agricultural systems must rely on the use and effective management of internal resources. Based on the information obtained throughout a series of experiments last years we have proved that the no-till direct-sown rice-vetch relaying cropping system dictates biological alternative which can augment, and in some cases replace, N fertilizers. Comprehensive discussions were made for the proposed system and it concluded that the system can offer an economically attractive and ecologically sound means of reducing external nitrogen input and improving the quality and quantity of internal resources, and consequently improving the farmers as well as the national returns.

If the atmospheric concentrations of greenhouse gases double, the annual temperature increase in mean surface temperature relative to 1990 will be about 2.0 to $2.5^{\circ}C$ and the annual precipitation increase about $15{\%}$ by 2100 in Korea. When the temperature rises $2^{\circ}C$, the annual temperature will be $13^{\circ}C,\;15^{\circ}C,\;and\;16^{\circ}C$ in Western Central, Yeongnam Basin, and Southern Coastal respectively. Consequently the crop period could be prolonged $10{\~}29$ days. In the case of gradual global warming, annual crops could be adapted to the changed environment by breeding, and the perennial crops should be shifted to ether area. If global warming happens suddenly over the threshold of atmospheric greenhouse gases concentration, then we shall have disturbance of ecosystem. When $2^{\circ}C$ higher than present, the optimum flowering date of rice plant delayed about 10 days, so it may not possible to adopt the fate with present japonica rices, therefore, the recommended characteristics of rice varieties are longer basic vegetative period, more late maturing and higher ripening temperature. Barley and wheat crops could be shifted to northern coastal areas and apple production areas should be shifted to those areas under $13.5^{\circ}C$ in annual mean temperature at global warming. Ideotypes of crops under climate changes should have such ecological characteristics that are indispensable to accomplish the sustainable agriculture under increased $CO_{2}$ and temperature condition as the diversification of genetic resources from yield-oriented to biomass-oriented characteristics with the higher potentials of $CO_{2}$ absorption and Primary production. In addition, a heat-tolerance, a pest resistance, an environmental adaptability and a production stability should be also incorporated collectively into our integrated agroecosystem.

The horticultural seed industry has made great progress in the last fifty years of its history after the independence of this country. The industry has accomplished self-sufficiency in major vegetable seeds and has even gained international competitive edge in certain crop seeds, particularly in hybrid cultivar development. However, the industry is facing a crisis at present coming from excessive competition among the domestic seed companies as well as the foreign currency crisis of the country. Several major seed companies have already been acquired by multinational corporations. Many people in the country as well as agriculturists are concerned about this situation. Although it is true that the industry is undergoing hard times, this crisis can be turned into a chance for making new progress depending on the joint efforts of the groups responsible, i.e., private companies, public institutions, and policy makers. Therefore, we have to turn this crisis into an opportunity for self-reform and progress. We should not be discouraged or give up. We Propose some ideas for the Progress of the seed industry. Public institutions and policy makers should do such things in cooperation as 1) training human resources for future breeders, 2) securing a wide range of genetic resources and improvement of the management system, 3) basic science research including biotechnology, 4) releasing breeding stocks from germplasm enhancement through use of exotic accessions, 5) support for breeding region- or use-specific cultivars, and 6) collection of foreign agricultural information for breeding cultivars for overseas markets. Eventually the responsible group for the final development of commercial cultivars, production, sales and management is private companies. Therefore, private companies also should have to do their best to develop competitive cultivars with a missionary spirit and endeavor for both domestic and overseas markets in cooperation with public institutions. Management based on competition, professionalism and rationalism is also urged. We are going to conclude with optimism that we can make a new vault of progress once the private and public sectors closely cooperate for the development of Korean horticultural seed industry by overcoming this crisis.

Information Technology(IT) in agriculture will contribute to the agricultural productivities and cultures in farm areas. On the basis of the information and knowledge infra structure, If projects and applications in agriculture have grown up rapidly in past few years, but still being requested more endeavors for each sections of agriculture. Specially, Internet and Information Super High-way Network Techniques will brings many changes in the area of agricultural research and dissemination. In this paper, the current status and future prospects of If in the agriculture field was referred to briefly.

It is urgent and of great importance for us to integrate and systemize the agricultural Information system available in Korea. In order to modernize the new Korean agricultural information system, which is enable to enhance compatability of domestic agricultural production system to those of abroad, and to be ready for the era of information and communication, every individual effort and progress is to be evaluated and systemized based on an integrated network system. In this study a comprehensive review for the present status of the Korean agricultural information system was made, and to prohibit the progress and development of this sector were the barriers identified. A survey was carried out to assess specific agricultural information demanded by local farmers. For the efficient utilization of the local agricultural information, the role of agricultural colleges was emphasized.

Rural information sector is a strategic planning of agriculture in 21st century for the advancement of agricultural competive power and quality of life to farmers. In order to advance the agricultural competency and quality of life, firstly, it is necessary that rural information sector should focus on the foundation of agriculture and rural information. Secondly, it should construct an area of function and item in application systems. Thirdly, it must Improve to culture of agriculture and rural information. It should be able offer a variety of educational information to help build a recognition and accommodation of value of agricultural information. The agriculture and rural information sector is so desirable that an organization should take exclusive responsibility to maintain the public property of it and to guard it from variable pressure groups. Therefore, to the uninformed mind, it is desirable to build and nurture KICAFF(Korea Information Center for Agriculture, Forestry & Fisheries) which is empowered in the information business- instead of the government. This is necessary for agricultural information system preservation because law and institution corresponds with role and function of the information/education system.

For effective prevention of the spreading and outbreak of crop insects and disease pests, an intensive Pest surveillance system was established to predict their density changes, and distribution. After their initial establishment by either immigration or overwintering, it is necessary to anticipate how they spread out geographically and predict where/when outbreaks are possible. The two major tools, boundary layer atmospheric model (Blayer) and the geographic information system(GIS), have been being developed to facilitate the prediction of pest occurrence in recent days. We are also developing the PeMos (Pest Monitoring System) that is able to manage the pest surveillance data collected from 152 pest monitoring stations in Korea. These three system related to the pest surveillance should be integrated into an internet based comprehensive database management system to facilitate information resources systematically organized and closely linked. Considering various data types and large data size in each system, a new special information management system is suggested. The integrated system should express complex types of information, such as text, multimedia, and other scientific data under the Internet environment. This paper discussed the major three systems, GIS, Blayer, and PeMos, relevant to the crop pest surveillance, then how they can be integrated in a comprehensive system under the Internet environment.
