Emergy Analysis of Korean Agriculture

우리나라 농업의 Emergy 분석

  • Published : 2005.06.30

Abstract

With the industrialization in Korea, the economy has invested more resources on industry and less on agricultural production. However, agriculture is still an important industry, since the whole nation depends on rice for their living. And the proportion of agricultural land is relatively large, which leads issuing environmental aspects of agriculture in this country. This study was conducted to evaluate the environmental and economical aspects of agriculture in Korea, using system ecological concept, Emergy. The total Emergy inflow of Korean agriculture was $336.57{\times}10^{20}\;sej{\cdot}yr^{-1}$ in 2003. Emergy yield ratio, the ratio of non-renewable and imported Energy use to renewable Emergy use, was 5.21, which shows the agriculture in Korea has such a value as that of the world oil resources in 1986. Also, total agricultural product was $13.55{\times}10^{16}\;J{\cdot}yr^{-1}$ in 2003 and the Energy inflow was $121.09{\times}10^{20}\;sej{\cdot}yr^{-1}$. From these data, solar transformity of Korean agriculture was estimated as $8.68{\times}10^4\;sej{\cdot}J^{-1}$.
