□ Purpose&Contents
○ To support “Agricultural Environmental Conservation Programs” of Ministry of Agriculture, Food, and Rural Affairs of Korean government, data bases for environmental effects of the conservation practices for arable soil, water, air quality and associated changes in crop productivity was established through intensive literature review and field experiments. Using the data base, field manual for the implementing the practices ofconserving agricultural environment were developed.
○ The another purpose of this study is to derive village-specific practices package through analysis of farmers' acceptability and expert priority of agricultural environment conservation practices, and to evaluate the economic feasibility of practices and village-specific practices package.

□ Results
□ (Project 1)Evaluation of the Efficacy of Agricultural Environment Conservation Practices of Nutrient Management
○ Literature review
- Establishment of data base for the effects of soil testing fertilization and usage of slow released fertilizer on environmental conservation and crop yield.
- Establishment of data base for the effects of managing livestock manure by recycling facility, guideline for spreading compost and liquid manure, optimum use of compost and liquid manure
○ Field experiments
- Evaluation of nitrogen balance and rice yield under optimum fertilization with soil testing in demonstrative villages under agriculturalenvironmental conservation
- Evaluation of nitrogen balance and crop yield under Chinese cabbage with optimum management of livestock compost
○ Field manual for optimum nutrient input practices
- Development of field manual for soil testing fertilization, use of slow released fertilizer.
○ Field manual for optimum livestock manure use practices
- Development of field manual for the optimum use of livestock compost and the optimum use of livestock liquid manure.

□ (Project 2)Evaluation of the Efficacy of Crop Rotation Practices for Agricultural Environment Conservation
○ Field experiments
- Evaluation of nitrogen and phosphorus balance and rice yield under rice-green manure cropping systems
Evaluation of nitrogen and phosphorus balance and crop yield under corn-soybean cropping systems
○ Literature review
- Establishment of data base for the effects of agricultural crop residue recycling and Green manure cultivation with fallow season on environmental conservation and crop yield.
- Establishment of data base for the effects of control of insect pest by natural enemies and grass sward in orchard on environmental conservation and crop yield.
○ Field manual for nutrient input reduction practices
- Development of field manual for crop residue recycling, green manure cultivation with fallow season, and cropping systems.
○ Field manual for pesticide use reduction practices
- Development of field manual for control of insect pest by natural enemies, grass sward in orchard, weed control without herbicide, soilsolarization, and insect screens on greenhouse.

□ (Project 3)Evaluation of the Efficacy of Soil Loss Protection Practices for Agricultural Environment Conservation
○ Field experiments
- Investigation of the effects of surface cover with rice straw on loss of soils and nutrients from sloping uplands and on maize yields of thefields.
- Investigation of the effects of vegetated ridge and sand bag on loss of soils and nutrients from sloping uplands and on maize yields of the fields.
○ Literature review
- Establishment of data base for the effects of surface cover, vegetated ridge, sand bag, vegetative filter strip on environmental conservationand crop yield.
- Establishment of data base for the effects of sediment trap, bio-slope, diversion ditch on environmental conservation and crop yield.
○ Field manual for soil erosion prevention practices
- Development of field manual for surface cover, sand bag, vegetated ridge, vegetative filter strip, bio-slope between fields and water body, and diversion ditch surrounding fields.

□ (Project 4)Evaluating the Effect of Soil Tillage and Green Manure Management Practice on Agricultural Environment Conservation
○ Establishment of data for effect of agricultural practice for air quality management on crop productivity and conservation of agriculturalenvironment
○ Establishment of data for effect of agriculutal practice on reducing odor generated during animal husbandry
○ Bring out results of mitigation of greenhouse gases and change of crop productivity with different green manuring and tillage operation
○ Development of manuals of agricultural practice for conducting “agricultural environmental conservation program”.

□ (Project 5)Evaluation of the Efficacy of Agricultural Water Saving Practices for Agricultural Environment Conservation
○ DB establishment for (i) QE of the WSI effect in both the paddy and the upland, and in the cultivation under structure, (ii) QE of the effects of constructed wetlands and detention ponds on AWQ, (iii) field demonstration of the effects of natural vegetation and sediment trap in the edge of cropland on AWQ, (iv) QE of the cleaning effect of contaminated irrigation water resources and the planting effect of aquatic plants on AWQ.
○ Activity manual production for AEC with regarding to WSI and to both the cleaning of contaminated irrigation water resources and the planting of aquatic plants.

□ (Project 6)Priority and cost-benefit analysis of adopting Agricultural Environment Conservation Practices
○ Farmers’ acceptabilities and expert priority analysis by agricultural environment conservation activities.
Priority analysis through using AHP and BWS techniques.
Survey on farmers’ acceptabilities of practies.
Analysis of synergy, conflict, and substitution relationship of among practices.
Proposal of village specific practices package based on the comprehensive ranking of agricultural environment conservation practices, synergy, conflict, and substitution relationship.
○ Cost-benefit analysis of agricultural environment conservation practices
Setting the methods, target, and range of cost-benefit analysis
List the cost-benefits and a value chain by practices.
Calculating quantitative indicators by cost-benefit list by practices.
Analysis and evaluation of private and social benefits by practices.
Cost-benefit analysis and economic analysis for each empirical district cases and village specific practices package of agricultural environmentconservation practices.

□ Expected Contribution
○ Quantification of the effects of optimum nutrient management, nutrient input and pesticide use reduction, the control of soil erosion, water-saving, improving water quality, GHGs reduction etc. practices onenvironmental conservation.
○ Suggestion of comprehensive assessment of environmental conservation effect, crop yield change, and cost for recommended practices.
○ Enlargement of applicability and acceptability of conservation practices by farmers.
○ Use as supporting data to develop various incentive programs and policy measures to promote climate-smart farming and agricultural environment conservation program.
○ Provide a long and short term roadmap for agricultural environment conservation program and utilizing the smooth implementation of agricultural environment conservation programs of the Ministry ofAgriculture, Food and Rural Affairs.
○ Provide the supporting data to create the public functions of agriculture and implementation of public-purpose direct payment.
○ Use as a promotional material to inform the international community, including the OECD, of the improvement of agricultural environment indicators through practice of climate-smart agriculture.

< Expected contribution >
○ Contributing to the successful establishment of agricultural environment conservation programs by proposing customized agricultural environment conservation practices packages suitable for local environment.
○ Realization of climate-smart agriculture and improvement of agricultural environment through introduction of agricultural environment conservation practices.
○ Securing consumer confidence by resolving negative externalities and creating social benefits by improving the agricultural environment.
○ Consolidate the industrial status of agriculture by contributing to the maintenance and development of sustainable agriculture and rural areas by realizing climate-smart agriculture.
○ Respond to the international community's efforts to improve agricultural environment and sustainable agriculture by improving national agricultural environment indicators
