우리나라에서 수리불안전답은 전체 답의 20% 이상을 차지하고 있고, 총 수자원이용량 대비 농업용수 이 용량은 50% 수준으로 아시아 또는 세계 평균에 비하여 매우 낮은 편이다. 또한, 과거 설치된 수리시설물이 노후화되었고, 국가의 균형적인 농촌사회 개발, 그리고 국내 농업경쟁력 제고 측면에서 추가적인 농업용수 공급이 필수적으로 요구되고 있다. 그러나 실제 농업용수 공급사업과 관련된 타당성분석 사례를 살펴보면 편익항목의 설정, 분석방법 및 절차에서 일관성이 없는 경우가 많고, 이처럼 일관성이 결여된 분석은 사업의 타당성을 충분히 제시하지 못하게 되며, 결과적으로 사업의 신뢰도를 잃게 되어 투자의 우선순위에서 밀려나는 결과를 초래하게 된다. 본 연구에서는 편익산정에 앞서 농업용수 공급이 가지는 정성적인 가치를 생산측면, 소득/소비측면, 고용측면, 식량안보측면, 환경측면으로 구분하였고, 이 가운데, 편익산정 시 반영할 항목으로 생산증대편익과 가뭄피해 저감편익을 제시하였다. 본 연구는 농업용수 편익산정 방향을 제시함으로써 타당성조사 시 편익을 보다 실제적이고, 적극적으로 반영하고자 하였고, 향후 관련 사업의 추진 시 사업이 갖는 타당성을 보다 현실적으로 반영하는 데 기여할 것이라 판단된다.

How to determine rental rates of agricultural machinery operation is the most important factor for economic units which are consigned to practice agricultural operations. Economic units as consigner for agricultural operations include agricultural cooperatives, local government, and farm operators, and so on. Thus the methods to set a rental rate of agricultural machinery operation are different across these economic units. This study describes benefits and problems associated with the model of cost accounting which is used as a method to determine a rental rate of agricultural machinery operation, and suggests a theoretical desirability of the rental pricing method, based on an accounting system and information on costs.

In this study, the securing state of nationally indicated beneficial microbial resources was evaluated in an aspect of bio-diversity using their taxonomical information. Depending on the analysis result with the Margalef's richness or the Mehinick's index which are representative bio-diversity analytical indices, species diversity values was revealed as 8.537, 3.546 within bacterial resources, 3.349, 2.167 within fungal resources. Several developed or researched beneficial strains and spoilage microbes showed relative taxonomical relationship with comparation of their biological information. As a result, we propose the necessity or countermeasure method for preventing the microbial spoilage with the overhauling consideration of advanced research on agricultural microbiology covering crop endophyte beneficial/spoilage microorganisms.

This study researched the current occurrence status of viral diseases of solanaceous crops in the main production areas of Gangwon region, for four years from 2014 to 2018. From 2014 to 2018, in eight cities and counties including Chuncheon, CMV, BBWV2, PMMoV, TSWV, and PVY occurred in chilli peppers. In case of tomato, the research was performed in 2017 and 2018 while TSWV and TYLCV were verified in Chuncheon, Hoengseong, and Cheorwon. Especially, TYLCV occurred in Chuncheon region for the first time in 2017, which was verified in 2018. Lastly, the current occurrence status of viral diseases of bell peppers was researched in seven cities and counties like Gangneung, Hoengseong, and Cheorwon from 2015 to 2018. In the results, CMV, BBWV2, PMMoV, PepMoV, and TSWV were verified in bell peppers of Gangwon region. During the research period, there were no crops suspected or infected by BWYV, so that it is judged that there is no villiferous or infected aphid by this virus in Gangwon-do. Such results of this study could be used as the basic data for the stable production of crops through the early prevention of plant diseases occurring in the solanaceous crops of Gangwon region.

Paddy fields provide important habitats for biodiversity conservation within the agricultural ecosystem. Their importance is gradually increasing as their ecological value is better understood. Benthic macroinvertebrates dominate paddy fields. They play an essential role in maintaining the biodiversity of paddy ecosystems. This study aimed to analyze characteristics of benthic macroinvertebrate communities and main environmental factors affecting the distribution of golden apple snails (Pomacea canaliculata). Results showed that the diversity index (H') of the benthic macroinvertebrate community was the highest at the Sangju site (St. 12) but the lowest at the Sancheong site (St. 18). Total Dissolved Solids (TDS), salinity, and Electrical Conductivity (EC) values were the highest in Gimhae and Yeongam based on Canonical Correspondence Analysis (CCA). Numbers of P. canaliculata (m-2) were relatively low in Gunsan and Iksan where water temperatures were high. Therefore, changes in geographical characteristics and environmental factors might affect the distribution of P. canaliculata and characteristics of benthic macroinvertebrate communities. Results of this study can be used as primary data for biodiversity conservation and ecosystem service evaluation in agroecosystems.

This study investigated definition of care farming in which advanced countries in agricultural industry such as Netherlands and Belgium increase their interest and investment, and established a strategy for settlement and development of care farming industry in Korea. For achieving purpose of the study, literature review was implemented to analyze policy, system, related law, workforce of advanced countries in care farming, and experts' conference which consists of 9 representatives such as professors, researchers in areas of agriculture, health, education, horticulture, animal-assisted therapy was implemented. Also survey was conducted targeting 165 people of practitioners in care farming industry. For the result, the concept of care farming in Korea was defined as 'Industry and activity which promotes psychological social physical cognitive health of every Korean people by utilizing agricultural resources(plants, livestock, rural environment, rural culture) or related activity and output', and the purpose, resources, targets of care farming was determined by the definition.

기후변화에 관한 IPCC 제5차 평가보고서에 따르면 최근 나타난 기후 관련 극한 현상인 폭염, 홍수, 가뭄 등의 영향에 대해 생태계가 현재의 기후 변동성에 상당히 취약하게 반응하며, 기후변화를 위험에 초점을 맞추어 평가함으로써 대응책을 마련해야 한다고 강조하였다. 기후변화에 따라 강수량 패턴과 수문학적 시스템이 변하면서 수자원의 미치는 영향과 취약성, 적응에 대한 연구의 필요성이 요구되고 있으며, 농업용수를 비롯한 수자원 관리 기술 및 적응역량을 강화하는 것이 필요하다. 수리답 면적에 대한 농업용수 공급의 61%를 차지하는 농업용 저수지의 경우 과거 10년 한발빈도로 설계되어 최근의 연속적인 가뭄 사상으로 인한 낮은 저수율을 나타내어 가용 수자원의 부족이 발생하였다. 이에 따라 저수지 설계 당시와 상이한 환경 및 기후의 변화로 농업용수 공급체계의 상황변화에 따른 용수공급능력 및 이수안전도의 재평가가 요구된다. 일부 가뭄대책지구에 대하여 기후변화에 따른 현장여건 변화 (논면적, 영농패턴, 작부시기 등)를 반영한 이수안전도를 재평가함으로써 농업용 저수지의 용수공급에 대한 정량적 분석이 수행되었다. 저수지별로 기후변화 및 현장여건 변화에 따른 영향이 다르므로 전국 농업용 저수지를 대상으로 확대, 적용하기 위해서는 저수지 특성을 분석하여 비슷한 패턴을 갖는 저수지로 유형화하기 위한 작업이 필요하다. 본 연구에서는 농어촌공사 관할 3,394개의 농업용 저수지를 대상으로 지역에 따라 인자별 군집분석을 실시하여 국내 농업용 저수지의 이수안전도 변화에 따른 물 공급 잠재능을 재평가하고자 한다. 본 연구의 결과는 기후와 영농방식, 지역별 특성 등 상호간의 관계를 고려한 농업용수관리와 유사한 특성을 갖는 지역계획의 추진단위를 결정하거나 지역간의 비교우위를 고려한 한해 대책 등과 같은 농촌지역개발계획 등에 활용할 수 있을 것으로 기대한다.
