This study was conducted to investigate the effects of environmental sound rice farming method on the productivity of rice industry which may result in impacts on the staple food securities. Recently fanners have been concerned about adopting new rice cultivation method such as organic and low input farming system in which fertilizer and pesticide can be substantially reduced so as to alleviate the burden of agro-ecosystem. However, It has been argued about whether or not there are negative impacts on the self sufficiency rate of food, income of farm household and technological adaptability. Therefore this study examined the productivity trend of environmental rice farming system and predicted the long term rice self-sufficiency rate when environmental rice farming system are adopted by assuming various scenarios. It was estimated that rice self-sufficiency rate can be decreased up to 52.2% by 2010. Based on the analysis of results, policy recommendations for environmentally sound rice farming were suggested as follows: 1) gradual adopting and transferring of environmental rice cultivation method, 2) increasing profitability of rice growing fanners 3) developing the farm level technology specific to Korean farming condition, 4) institutionalization of direct payments for encouraging environmental rice fanning.

Duck farming restriction refers to a program in which duck farms suspend their operations for a certain period at times when the risk of avian influenza (AI) is high and receive compensation from the Korean government. This study analyzed the effect of this duck farming restriction on the incidence of AI using data on regional AI incidence rates, the program participation rate, and characteristics of poultry farming in 2016 (before the implementation of the restriction), as well as data from 2020 and 2021 (when new AI outbreaks occurred). In this study, the treatment group was divided into five subgroups according to the policy participation rate and a difference-in-difference (DID) estimation was conducted using certain covariates, in this case the average number of ducks raised, the land area, the number of high-susceptibility farms, the number of low-susceptibility farms, the average number of farms within a 3 km radius, the average distance to the nearest farm, and a year dummy. The results showed that when more than 30% of all duck farms in a region participated in the farming restriction, it had a statistically significant effect on the incidence of AI. Specifically, when more than 30, 40, 50, and 60% of all duck farms participated in the farming restriction, the AI incidence rate decreased by 0.7184, 1.0025, 1.5844, and 1.5843%p, respectively.

작물 재배 방법이 토양의 미생물 군집 특성과 화학성에 미치는 영향을 검토하였다. 이를 위해서 다섯 곳의 고추 관행 재배지와 다섯 곳의 유기농 재배지 토양을 채취한 후, 16S rRNA 유전자 기반의 파이로시퀀싱 기법으로 미생물 군집을 조사하였다. 분석 결과 총 22개의 세균 문으로 구성되었으며 Proteobacteria 문(33.0 ± 5.7%), Actinobacteria 문(19.9 ± 9.7%) 및 Firmicutes 문(13.6 ± 5.0%)이 우점하였고, 이들은 전체 상대풍부도의 66%를 차지하였다. 고추 관행 재배지와 유기농 재배지의 미생물 군집 분포를 비교했을 때 전반적으로 서로 다른 군집 특성을 나타내었다. 또한 관행 재배 토양에서는 Actinobacteria 문과 Chloroflexi 문이 상대적으로 풍부하였고, 유기 재배 토양에서는 Proteobacteria 문과 Firimicutes 문이 상대적으로 풍부하였다. 특히 Streptomyces 속과 Bacillus 속의 상대풍부도는 관행 재배 토양과 유기 재배 토양 간에 상당한 차이를 보였다. 또한 토양 화학 성에 의하여 세균 군집 변화가 관찰되었는데, Proteobacteria 문의 Rhizobiales 목과 Actinobacteria 문의 Streptomyces 속은 pH에 의해 세균 군집이 바뀌었고, Firimicutes 문의 Bacillus 속은 유기물 함량에 의해 군집 분포가 바뀌었다. 본 연구결과는 재배관리에 따른 토양의 물리-화학성의 변화가 미생물 군집 분포에 뚜렷하게 관련(p<0.05)되어 있다는 것을 보여주었다.

In order to obtain the basic information for the optimal settlement planning in the reclaimed area, various existing settlement conditions on reclaimed farming village were analysed through a case study of in-and-round farming villages in Deuk Ryang Reclaimed Area. By comparison study between in-and-around villages, the allocation policy of farming settlement in the samll and medium scale area was proposed. The results obtained in this study were as follows ; 1.The population structure of the inner village(Ansim village) had become worse than the around village during 1976~1981 period from the viewpoint of total and female emigration ratios. Especially, the originally unbalanced sex ratio of Ansim village had worsen to the unacceptable ratio of 1.5 : 1(male : female). Therefore, the structural stability of the population should be carefully improved in the newly reclaimed farming villages by the systematic long-term controlling machanism.2.The farming status of Ansim village was much lower than the around villages viewing of the cultivated acreage and agricultural machinery stock Therefore, the continuous and intensive governmental support different from the existing farming area should be required for the settling of reclaimed farming. 3. The regularity of the village site as a planned village, though pursed in the first phase of village construction, had been severely disturbed inflowing of squatters. Recently, there are increasing vaccant houses in the village, and the level of living amenities and personal mobility of Ansim village are much lower than the around village. So, now, the physical structure of the village should be improved to the level of village reconstruction or new village construction. 4. The cultivated area of Ansim village leans to the south side which would be unfavoured by the farmers of the around villages, while its distributing pattern should be concentric around the village site. This phenomenon disturbs the central fuction of the planned farming village. In this respect, role assignment, relationship and balance of competence in farming activities should be planned between in-and-around villages in the reclaimed area from the initial stage. 5. Putting together the above results in this study, the farming and living conditions of Ansim village threaten its existence as a planned new farming village in the reclaimed area. And, so, the full scale reconstruction of village structure, including moving to the new site, should be designed as soon as possible. Although further many studies should be carried out, it would be sure that the new village planning should be reconsidered in the small and-medium scale reclamation works.

Community-based precision farming is a new concept of agricultural systems, which leads to organize groups of wise farmers and technology platforms in Japan. The wisdom farmers create a rational farming system to manage hierarchical variability: variability in farmers' community as well as variability of within-field and between-field. The technology platform develops and provides three key-technologies: mapping technology, variable-rate technology, and decision support systems available for rural constraints. Advancement of bio-production robots leads precision farming to the next level, where two technological innovations: how to produce and manage information-oriented fields and information-added products, can be attained.

최근 들어 농업생산기술 분야에서는 정밀농업이라는 용어 가 자주 등장하고 있으며 내용의 다양성에 기인하여 정밀농업(precision farming, precision agriculture), 처방농업(prescription farming), 국지 적 농업(site-specific filming, farming-by-the-fpot), 변량형 농업(variable rate agriculture)등의 여러 가지 명칭으로 불리고 있다. 현재 서구에서 새로운 농업의 표준이 되어 가고 있는 정밀농업의 근 특징은 기존 농업이 거시적, 통계적 접근방법임에 비교하여 미시적, 변량적 접근방법에 기초한다는 것이다.(중략)
