Abstract

The amount of water resources identified by water balance analysis are usually used to formulate water resources plans. However, this does not consider the trade in goods between countries. It is possible to use virtual water to come up with a supply and demand plan by looking at the export and import of products. This is because it looks comprehensively at the direct water use (water resources within the region) and indirect water use (water resources of other regions from imported products). Yet South Korea does not actively use the concept of virtual water in the national water resources plan. There is difficulty with calculating and identifying the appropriate virtual water amount as many of the research papers present only few of the cases or omit the calculation process. This paper introduces detailed water footprint values for calculating the virtual water trade for South Korea. The international movement, water footprint, and virtual water trade of agricultural and livestock products are presented and compared to existing research. The water footprint and virtual water research in this paper can be utilized as baseline data for future researchers.

수자원 수급계획은 보통 물수지분석에서 파악된 수자원의 양에 따라 수립한다. 그러나 그것은 상품의 이동과 같은 국제교역을 고려하지 않은 폐쇄적인 수급계획이다. 물수지분석에 가상수 개념을 도입하면 상품의 수출량과 수입량을 고려한 수자원 수급계획을 수립할 수 있다. 기존에 활용하는 직접적인 물 사용(지역 내에서 가용한 각종 수자원)과 가상수를 고려한 간접적인 물 사용(지역 외에서 수입한 상품생산에 소요된 타 지역의 수자원)을 종합적으로 고려하기 때문이다. 그러나 한국에서는 아직 가상수의 개념이 국가 수자원계획 수립에 본격적으로 반영되고 않고 있다. 국내외에서 발표된 가상수 산정연구 논문에서는 가상수 산정과정이 생략되거나 일부만 제시된 사례가 많다. 따라서 가상수의 산정과정 및 거래량의 적절성을 파악하여 실무에 활용하는데 큰 어려움이 존재하고 있다. 본 연구는 한국에서 수출입하는 가상수량 산정을 위한 물발자국 적용값을 구체적으로 제시하고자 한다. 농축산물의 국제 이동량, 물발자국 적용값, 가상수 거래량을 파악하는 과정을 기술하고, 이를 기존연구와 비교하고자 한다. 따라서 본 연구에서 제시한 산정과정과 산정기준은 물발자국 및 가상수 연구를 수행하는 연구자들에게 유용한 기초자료를 제공할 것이다.
