Abstract

An emergy analysis of the main energy flows driving the economy of humans and life support systems was made including environmental energies, fuels, and imports, all expressed as solar emjoules. The total emergy use (4, 373 E20 sej/yr) is 90 per cent from imported sources, fuels and goods and services. The emergy flows from the environment are modest, because the share of global inputs such as ruin and geological uplift flux is modest. Consequently, the ratio of outside investment to attracting natural resources is already large, like other industrialized countries. The population level is already in excess of carrying capacity. The emergy use per person in Korea indicates a moderate emergy standard of living, even though the indigenous resource is very poor. If the present economy were running entirely on stored reserves of fuels, soils, woods, etc., it would last about 2 years. Its carrying capacity for steady state on its renewable sources is only 3.3 million people, compared to 43.3 million in 1991. Continued availability of foreign oil at a favorable balance of emergy trade, currently about 7 to 1 net emergy, is the basis for present economic activity and must decrease as the net emergy of foreign oil purchased goes down. Close economic integration with Middle East may determine how long this is possible in the future.

환경개발과 경제발전을 조화롭게 하여 지속가능한 것으로 발전시킬 수 있는 EMERGY <분 석법올 이용하여 한국의 환경과 경제에 적용하였다 .. 1991년 한국이 사용한 총 EMERGY량은 4 4,373 E20 sej/yr 로서 이중 약 90%가 외국에서 수입해 온 원유, 광물자원 그리고 상품 둥으로 부터 비롯된 것이다. 국내의 환경자원으로부터의 EMERGY 사용량은 강수량과 지질학적 작용 이 유사한 다른 국가와 동일한 수준이었다. 환경자원에 대한 경제적 이용률은 선진국의 이용률과 같은 수준이어서 제한된 환경자원에 대한 압박이 클 수밖에 없음을 알 수 있었다. 인구 1인당 사용량은 부폰자원이 빈약하고 무 역수지의 적자에도 불구하고 약 3.4배의 EMERGY교역의 흑자로 인하여 경제선진국의 값과 비슷하였다. 그러나, 현재의 소비수준으로 국내의 환경자원에만 의존할 경우 약 2년 정도밖에 지속될 수 없으며, 정상상태에서의 인구 수용능력은 ’91년 현재의 인구 4천 3백만명에 비하여 3백3십 만명 에 불과하다. E EMERGY 분석을 통해서 볼 때 한국의 경제활동은 환경에 지나친 압박올 주고 있으며 성 장의 지속은 중동국가를 비롯한 산유국과 경제적인 수지가 아닌 EMERGY 수지의 관점에서 얼마나 효율적으로 상호관계를 유지하느냐에 달려 있다.
