Ammonia emission from the agricultural sector contributes almost 78% of total ammonia emission in Korea. The current ammonia emission estimation method from fertilizer application has high uncertainty and needs to be improved. In this study, we propose an improvement method for estimating the amount of ammonia emission from agricultural land with improved spatiotemporal resolution using Farm Manager Registration Information System and criteria for the fertilizer. We calculated ammonia emissions by utilizing the 2020 cultivation area provided by Farm Manager Registration Information System for 55 kinds of upland crops cultivated in the field area of the farmland. As a result, soybeans were the most cultivated field crop in 2020, and the area of cultivated land was surveyed at about 77,021 ha, followed by sweet potatoes 22,057 ha, garlic 20004 ha, potatoes 17,512 ha, and corn 16,636 ha. The month with the highest ammonia emissions throughout the year was calculated by emitting 590.01 ton yr-1 in May, followed by 486.55 ton yr-1 in March. Hallim-eup in Jeju showed the highest ammonia emission at 117.50 ton yr-1.

Food consumption pattern changes, including a decrease in rice consumption and increasing demand for fresh vegetables, along with declining food self-sufficiency rate, more importance is being placed on agricultural industry within Korea. Taking these changes into consideration, there is an increasing necessity for managing upland fields on agricultural sector to revitalize agricultural land use. Therefore, in this study, upland use type was classified into agricultural economic, environmental conservation, and rural social frames. The purpose of this study was to suggest upland use plan with farm manager registration information and spatial data. As results of this analysis, the mean area of agricultural economic frame in Haenam (16.47 ha) was found to be wider than Muan (3.17 ha), and scale improvement zones (54 zones) were located in only Haenam. In case of environmental conservation frame, there's no zone of scenic agriculture land in both study areas, but landuse transition zones were located in Muan (278 zones) and Haenam (604 zones). Agro-healing zones of rural social frame were 1,018 zones in Muan and 1,588 zones in Haenam and kitchen garden sites were 342 zones in Muan and 370 zones in Haenam. These results could be used when we establish the plan of an agricultural infrastructure project or select places for a collaborative agricultural land use project.

It is necessary to prepare a stable production base in advance for a change in the global grain market, and it is required to prepare comprehensive countermeasures such as securing technical skills and cultivation technology. Therefore, Korea, which relies on imports of major grains other than rice, could be exposed to a food crisis at any time unless the self-sufficiency rate of grains is improved. In order to respond to this new food crisis, it is necessary to find ways to efficiently utilize rice fields to increase the domestic grain self-sufficiency rate. From this point of view, interest and demand for the generalization of farmland that can be used as paddy fields and returned to paddy fields are increasing, and related research is also being continuously performed. In order to select a multipurpose farmland project site, this study extracted farmland containing 10% or more purchased and stockpiled farmland through spatial analysis (buffer, dissolve, intersect, etc.), and finally presented areas subject to multipurpose farmland projects. The target site for the multipurpose farmland project was finally selected by integrating data onto a point-by-point basis so that the current status of farmland purchased and stockpiled, Farm Manager Registration Records, and the Korean Soil Information System data (drainage classes, surface soil texture, field-suitability classification, etc.) can be used in combination. There are 175 areas where the multipurpose farmland is possible. Incheon 2, Gyeongbuk 40, Gangwon 2, Chungbuk 7, Chungnam 48, Jeonbuk 34, Jeonnam 19, Gyeongbuk 15, Gyeongnam 8. Chungcheongnam-do has the most target site for the multipurpose farmland project, and Gangwon-do is the least. It is expected to contribute to new commercialization and business expansion by deriving business areas by identifying the scale of the farmland multipurpose farmland project using Farm Manger Registration Records and spatial data.

As food consumption pattern changes (reduced rice consumption and increased consumption of fresh vegetables), managing upland fields became a greater priority. However, the agricultural infrastructure projects have been focused on rice farming, and the infrastructure level to support dry fields cultivation is insufficient. The purpose of this study was to spatial distribution analysis of these dry fields with farm manager registration information. Using FRAGSTATS, we analyzed landscape indices (TA/CA, NP, PD, LSI, LPI, PLADJ, COHESION, CONNECT, AI) of farmlands in which farmers in 13 regions (Si or Gun) cultivated dry-field crops. As results of this analysis, the total area of the fields in Naju-si, Hampyeong-gun and Suncheon-si were found to be wider, but the average area of a patch in Youngam-gun, Hampyeong-gun and Jangseong-gun were wider than other regions. On average, each farmer had farmlands containing of 1.7~2.4 patches and cultivated crops in fields of 0.2~0.5 ha. Farmlands of Hampyeong-gun, Youngam-gun, Naju-si showed high values in adjacency indices, however the farmlands of Suncheon and Gwangyang showed fragmented distribution with low values in adjacency indices. These results of fragmentation analysis of farmlands could be used when we establish the plan of an agricultural infrastructure project or select places for a collaborative agricultural management business promotion project.

정부는 시장개방에 따른 농가의 경영불안정을 완화하고 농가소득보전을 위해 다양한 형태의 직접지불제를 운용하고 있다. 그러나 농업부문의 직불제는 농업정책의 중심으로 농가소득 안정화의 중요한 역할을 수행하는 핵심적인 정책수단으로 자리잡고 많은 예산이 지출됨에도 불구하고 직불금 수급실태와 소득안정기여도 등 정책효과에 대한 분석이 미흡한 실정이다. 따라서 본 논문에서는 농식품부의 2014년과 2015년의 농업경영체 D.B.를 이용하여 직불금 농가단위 실태분석, 시사점을 도출하고, 제도의 성과평가를 시도하고자 한다. 본 연구에서는 평균 거시지표를 활용한 농업분석 등 기존의 연구 틀에서 벗어나, 경영체 DB를 활용하여 농가단위 제도의 성과평가를 시도하고 시사점을 도출한 것이 특징이라 할 수 있다. 직불금 수급실태와 성과평가를 시도한 결과, 직불금 수급액 분포가 정상분포곡선보다 왼쪽으로 많이 치우친 것을 알 수 있었다. 2014년 농업경영체DB에 의하면 전체 농업경영체의 약 절반 수준인 49.3%의 농가가 연간 10만 원도 안 되는 직불금을 수령하고 있는 것으로 나타났다. 영농규모가 클수록 소득증대효과와 소득안정화효과 모두 크게 나타났는데, 이는 면적에 비례해서 직불금이 높았기 때문이다. 고령농업경영체일수록 직불금에 의한 농가소득 기여도가 높게 나타난 점은 장점으로 평가되나, 영농규모가 0.5ha미만의 소규모 농가의 직불금의 농가소득 기여도가 3% 수준에 불과한 반면, 10ha이상의 대규모 농가의 직불금 농가소득 기여도가 29.4%로 높게 분석되었다. 대규모 농가는 소규모 농가보다 농업소득은 10배 차이인데, 직불금 수급액은 110배를 더 받는 것으로 분석되어, 향후 직불제도 정책개선 및 수정이 요구된다.
