韓国
Last Updated : 07 February 2023.
GDPの伸びに伴い、韓国の一人当たりの水使用量も増加してきましたが、近年は顕著に減少しています。年間降水量の約3分の2は、6月から9月までの期間に降るため、水利用可能量の季節的な変動は、気候変動が原因とみられる水関連の災害の増加とともに、水管理の課題として残っています。韓国には、漢江 (Han River)、錦江（Geum River）、洛東江（Nakdong River）、栄山江－蟾津江（Yeoungsan River-Seomjin River）という4 つの主要な河川流域があります。

Institutional Arrangement of water
Responsibilities which were previously spread across different ministries (for example, large rivers/streams were under MLIT, small streams/creeks were under the Ministry of Interior and Safety, lakes were under Ministry of Agriculture, Food and Rural Affairs, and sewerage was under the Ministry of Environment) were all restructured for management under the Ministry of Environment. The National Institute for Environmental Research (NIER) conducts monitoring of environmental water quality.
The following local environmental agencies conduct monitoring and legal enforcement:
- Han River Basin Environmental Agency
- Geum River Basin Environmental Agency
- Nakdong River Basin Environmental Agency
- Yeongsan River Basin Environmental Agency
- Daegu Regional Environmental Agency
- Wonju Regional Environmental Agency
- Jeonju Regional Environmental Agency
These regional environmental agencies, together with the Water Environment Research Center, Research Institute of Public Health and Environment, K-Water, and the Korean Rural Community Corporation form a multistakeholder consortium that implements the water quality monitoring framework.”
