모든 국민이 언제든지 충분한 식량을 충족할 수 있는 상태를 나타내는 식량안보에는 식량의 가용성, 식량의 활용성, 식량의 안전성, 식량의 접근성 네 가지 측정 요소가 있다. 식량의 가용성이란 국내 생산과 수입량 등을 고려한 공급량의 확충 여부를 말한다. 본 연구에서는 한국 농업을 중심으로 농업인구, 경작지, 수입량, 수입 공급망 등 식량의 가용성을 대상으로 통계적 분석을 진행하고 시사점을 도출한다.

우리나라는 지난 10년동안의 농림부 통계 자료에 의하면 쌀의 생산량은 년간 400만톤 내외로써 큰 변화가 없었으나 인구증가로 인한 쌀의 소비량은 계속 늘어나서 쌀의 도입량은 해마다 늘고 있는 실정이다. 1971년에는 그 수입량이 무려 100만톤에 이르렀다.

This study aims to analyze the impact of China's iron ore imports and exports on the tramper freight rate of China. The import volume of iron ore in China, the export volume of steel products in China, and exogenous variables were used as independent variables. The dependent variables were BDI, BCI, C5, C10, C14, BSI, S2, and S3. Correlation analysis and regression analysis were conducted. The correlation analysis showed that China's iron ore imports were not related to the remaining BDI, BCI, BSI, C5, C10, S2, and S3, except for the C14 index. However, there was a positive correlation between the ship's space and international oil prices, and it was not related to China's Purchasing Managers Index (PMI). The export volume of steel products was negatively correlated with BDI, BCI, BSI, C5, C10, C14, S2, S3, and international oil prices, and was not related to iron ore imports, ship space, and China's PMI. In the verification of the hypothesis between China's iron ore imports and exogenous variables, China's PMI was rejected within the hypothesis. However, the hypothesis on international oil prices and ship space was adopted. In the verification of the hypothesis between China's steel export volume and exogenous variables, the hypothesis on BDI and the S3 index was adopted, and the hypothesis on BSI and S2 was rejected. In the analysis results of this study, the ship space and oil prices were adopted in all the hypothesis results. Domestic companies participating in the tramper shipping market will need to be prepared through continuous monitoring of related indicators.

우리나라 축산업은 과거 10년동안에 농업의 다른 어떤 분야보다도 크게 발전하였다. 그중에서도 양계산업은 사양 규모나 수수가 급격히 증가하여 이에 필요한 사료량 또한 급격히 증가하게 되었다. 가축사료중 곡류를 비롯한 농후사료는 주로 수입에 의존하고 있는 실정으로서 1967년도에는 사료 도입량이 45,300M/T에 불과하였으나 1971년도에는 464,000M/T으로 늘어났고 이에 필요한 외화도 322만$\$$에서 3,700만$\$$로 증가되고 있다. 이러한 현실에 비추어 수입의 주종을 이루고 있는 곡류는 옥수수 단일품목에 한하고 있으나 사료가격의 저렴화와 적기 확보를 위하여는 수입 곡류품목의 다양화가 필요하다고 인정되므로 가축사료에 있어서 수수의 사료적 가치를 옥수수와 비교 검토하기 위하여 다음과 같은 시험목적을 가지고 본연구를 착수하게 되었다. (1) 곡류의 상호 대체 이용이 가능시되고 있는 수수로서 옥수수의 일부 대체 시험을 실시하여 배합사료중 수수의 적정사용수준과 경제적 유의성을 규명하고, (2) 수수의 수입가격이 옥수수 수입보다 유리할 때 옥수수의 일부를 수수 대체수입하여 외화의 절약은 물론 사료가격의 적정화를 기하고자 함.

The nearly 75% of animal feed materials used for livestock production are imported every year in Korea. Most of imported feed ingredients are concentrated feeds such as com, wheat, soybean, soybean meal, etc. and they are used as the source materials for the production of assorted feed. The imported concentrated feeds are high in nitrogen and phosphorus. Therefore, the consistent import of feed ingredients may cause an increase of nutrient deposit in our agricultural ecosystem. In the current review, it was discussed with the situation of the feed importation and its nutritional composition to evaluate the nutrient load by the imported feeds onto agricultural ecosystem. The nutrient load caused by imported feeds in agricultural environment was compared with the nutrient demand for crop production. The amounts of N, $P_2O_5\;and\;K_2O$ introduced by the imported fteds in Korea were 371, 140 and 143 Ktons. And, the N, $P_2O_5\;and\;K_2O$ loads excreted from imported feeds in livestock were 148, 84 and 86 Ktons of N, $P_2O_5\;and\;K_2O$ and These nutrient loads by the imported feeds are at the percentage of N 52%, $P_2O_5$ 52% and $K_2O$ 42% in the comparison of total nutrient amounts excreted from livestock animals in Korea. The 82.3% of nutrients excreted from livestock was recycled to crop land as compost and liquid fertilizer, and the others were discharged to river after water treatment processing or disposed to ocean. Also, passing through the recycling process far the production of compost and liquid fertilizer, the amount of nutrients was reduced by the ammonia vaporization of livestock feces and urine. Accordingly, N 81, $P_2O_5$ 74 and $K_2O$ 76 Ktons in the nutrients excreted from livestock were estimated to be utilized in the crop land. Consequently, it was estimated that 44, 48 and 69 Ktons of N, $P_2O_5\;and\;K_2O$ were taken up with crops in the consideration of the ratio of mineralization, and the amounts of leached or deposited N, $P_2O_5\;and\;K_2O$ in crop land were estimated to be 37, 27 and 7 Ktons, respectively. It is estimated that 12%, 34% and 48% of N, $P_2O_5\;and\;K_2O$ introduced by the imported feeds were used by crops, and 10%, 34% and 5% of N, $P_2O_5\;and\;K_2O$ were leached or deposited in agricultural ecosystem. Therefore, considering the leached and deposited amounts of N, $P_2O_5\;and\;K_2O$ originated from the imported feed ingredients, the consistent import of feeds may gradually increase the nutrient load onto agricultural ecosystem.
