ABSTRACT Strategies for Establishing Environmentally-Friendly Agricultural System in Korea Under the pressure of population growth and cultivated acreage scarcity, production intensification for high productivity has raised the issues of environmental degradation in the agricultural sector. Environmental burden of agricultural sector depends on farming technology and site-specific characteristics. Thus, an appropriate approach to solving agro-environmental problems should consider the carrying capacity at regional levels. The objectives of this study are to analyze environmental loading in specific regions and to formulate strategies for establishing environmentally friendly agricultural system using a material balance model and a strategic approach. In mapping out the strategies, a system perspective is essential which is envisioned in its broadest sense, from the individual farm, to the local and national ecosystems affected by this farming system both locally and globally. A system approach gives us the tools to explore the interactions between ecological and socioeconomic aspects of our environment. A system approach also implies interdisciplinary efforts in research. In this note, this study is accomplished through the corporative works with multidisciplinary approach including Korea Rural Economic Institute, National Institute of Agricultural Science and Technology, and Korea Environment Institute. The two study areas are selected the Hongseong county at Chungnam province and Okcheon county at Chungbook province. The organization of this study is summarized as follows: In the Section 1, the problem statement, study objectives, and previous literature review are briefly discussed. Section 2 outlines the integrated approach to analyzing environmental burden of agricultural ecosystem and to estimating regionally based entropy. Section 3 presents policy programs for transforming into environmentally friendly agriculture from conventional practices. This section suggests basic principles for developing policy programs. In addition, economic incentive schemes, quantity regulation, and agri-environmental programs are briefly discussed and then major countries' agri-environmental programs are reviewed for benchmarking policy programs. Section 4 analyzes and diagnoses environmental burden and carrying capacity in the specific watershed areas using regionally-based material balance model. In addition, farmers' responses on environmentally friendly agricultural system are surveyed. Section 5 maps out strategies for managing appropriately regional agri-environmental resources such as the best management practices, life-cycle assessment, and regional-based natural cycling system. Finally, Section 6 presents brief summary and concluding remarks. The materials balance approach provides a method for assessing nutrient surpluses of specific regions, and hence their environmental loads. This approach is based on both the first law and the second law of thermodynamics in a closed system which addresses the problem of environmental loading in the agro-ecosystem. It involves and aims, at the various actors influencing nutrients management at different levels. A quantitative diagnostic phase, to determine nutrient management and economic performance in existing farming system, is followed by a targeted process of participatory development of integrated nutrient management technologies and formulation of facilitating policy instruments. Further development of the approach is required through inclusion of social disciplines, extrapolation of results to regional area. In order to mapping out the strategies, a stylized strategic approach which consist of strategic analysis, strategic choice, and strategy implementation is employed. Strategy analysis is conducted by SWOT (Strengths, Weakness, Opportunities and Threats) analysis and scenario analysis. Strategic choice is carried out making a priority on suggested agri-environmental policy programs using an analytic hierarchy process (AHP). Based on strategic analysis and choice, strategy implementation suggests establishing infrastructure (human resource, education, database, and marketing), conducting policy mix with environmental regulations and economic incentives, and renovating institutional and legal framework for establishing environmentally friendly agricultural system. Major findings of the study present regional-based nutrient balance situation in specific two study areas. Annual environmental loads of nitrogen and phosphorus from Hongseong county in 2003 are estimated at 2,676 ton and 1,242 ton, respectively. In addition, Okcheon county is estimated 443 ton in nitrogen and 258 ton in phosphorus. The results show that the amount of macro-nutrients based on ingredients are over-supplied 100.7 percent in Hongseong county and 30.9 percent in Okcheon county. The oversupplied macro-nutrients will affect the agricultural ecosystem in both counties negatively by being discharged and leached to the soil, ground and surface water. Based on an evaluation of the results of this case study, several suggestions are offered for managing material balance in specific areas. The most important thing is to establish best management practices and natural cycling agricultural system. To minimize the high surplus and losses of plant nutrients from agricultural system the input of nutrients to the system needs to be reduced. This can be solved by increasing recycling within the system. In this study, illustrated examples are presented showing that it is possible to conserve and minimize the losses of nitrogen and other plant nutrients through systematic recycling within agro-ecosystem through integration of crop and livestock sectors. However, to achieve high levels of production and recycling efficiency, there needs to be a good balance between the intensity of livestock production and crop production acreage at regional levels. Assuming that these principles are followed, size of livestock operations (specially swine and pigs) needs to be significantly decreased in Hongseong county. Researcher: Chang-Gil Kim et al.
