초록

물 발자국(Water footprint)은 단위 제품 및 단위 서비스 생산 전과정(life cycle) 동안 직접 및 간접적으로 이용되는 물의 총량지표를 나타내는 것을 의미한다. 현재까지 산업별 및 제품에 대한 물 사용량과 관련된 자료가 잘 구축되어져 있지 않으며 특히 많은 물이 사용되어지는 농업 생산 제품에 대한 물 사용량에 대한 자료는 전무하다고 할 수 있기 때문에 각 제품에 대한 물 사용량 자료 구축은 중요하다고 할 수 있다. 본 연구에서는 우리나라의 수자원 이용 형태 중에서 가장 큰 부분을 차지하는 산업 분야인 농업 산업에서 쌀 생산을 중심으로 8개 지자체(강원, 경기, 경북, 경남, 전남, 전북, 충북, 충남)를 범위로 하였으며, Cropwat 8.0 모델을 이용하여 물 사용량을 산정하였다. 본 연구의 결과로 쌀 제품의 간접적인 물 사용량은 경북 지역이 $1,356.68m^3/ton$으로 가장 적은 물 사용량을 가졌으며, 전남지역이 $1,669.54m^3/ton$로 가장 많은 물이 사용되는 것으로 산정되었다. 8개 지자체의 평균적인 물 사용량은 $1,487.87m^3/ton$으로 산정되었으며, 쌀 밥 한 그릇 양의 밥(130 g)을 지을 때 쓰이는 직접 물의 사용량 및 간접 물 사용량을 고려한 총 물 발자국 산정 값은 193.61L로 산정되었다. 본 연구결과를 바탕으로 농업 분야 및 전 산업 분야로 확장하여 제품별 물발자국 산정이 필요하며 데이터베이스 구축이 필요하리라 사료된다.

The water footprint of product and service is the total volume of freshwater consumed, directly and indirectly, in the life cycle of a product and service. Up to date, water consumption data for industries and products were not well quantified and developed. Especially it is important to construct for agriculture industry which consumes lots of water. In this study, by using Cropwat 8.0 model, we tried to evaluate regionalized water consumption related with rice production in agriculture industry in eight regions (Gangwon, Gyeongi, Gyeongbuk, Gyeongnam, Jeonnam, Jeonbuk, Chungnam, Chungbuk). As a result, Gyeongbuk region has the lowest water consumption in rice production, which is $1,356.68m^3/ton$, on the other hand, Jeonnam region has the highest water consumption ($1,669.54m^3/ton$). By using the average indirect water consumption ($1,487.87m^3/ton$) of eight regions and direct water consumption, the total water footprint for the rice amount of rice bowl size (130 g), which is 193.6 L was calculated. Based on this research approach, we should develop water footprint database of all agriculture products and expand to other industrial sectors.
