The Environmental Movement Alliance and Korea River Restoration Network commented on an article in the Chosun Ilbo that “the Ministry of Environment actually created a ‘falsified report’ to push the dismantling of the Han River and Nakdong River Weirs,” and “Korea’s environmental policy retreats to anti-intellectualism by the Chosun Ilbo.” I’m worried that it will happen,” he said.
The Chosun Ilbo on the 18th In the article, “It was confirmed that the Ministry of Environment, which ordered a research service to analyze the economic feasibility of dismantling the Han River and Nakdong River, intervened in the preparation of the report, and included directly in the report, such as ‘dismantling the weir is beneficial for water quality and aquatic ecosystem improvement'” did. “Among the data used in preparing the report, it was found that there were no actual data that could compare actual changes in water quality and ecosystem before and after the weir was opened.” reported that This newspaper reported that the Ministry of Environment used △water quality prediction modeling data, and the Ministry of Environment gave guidelines to use only △COD (chemical oxygen demand) for water quality evaluation.
Regarding this, the Korea Federation for Environmental Movement and the Korea River Restoration Network released a comment on the 19th and said, “The water quality modeling and conditional value evaluation methods used in the economic evaluation of the Han and Nakdong Rivers are not ‘fabricated’ by a few people, but are decided by the National Water Management Committee. If the Chosun Ilbo insists, are all economic evaluations using chemical oxygen demand (COD) in river and lake water quality indicators or similar methods fabricated?” he asked. He continued, “It is natural to select COD as an indicator of water quality. This was decided when the Geum River and Yeongsan River weir treatment plans were reviewed, and the chemical oxygen demand (COD) that can reflect the green algae generated by the installation of the beam is appropriate to model the situation in which the river flows freely through the dismantling of the beam.” rebutted
These environmental groups also said, “Actual data through floodgate opening does not directly show the benefits of dismantling weirs because there is a stagnant section in the fixed weir section, and variables such as the inflow of pollutants such as tributaries are involved.” He stated that it was inevitable and demanded that “if you want to use actual data through weir opening to compare changes in water quality and aquatic ecosystems following the dismantling of weirs, agree to the opening of the floodgates.” They said, “We also open the sluice gates of the Han and Nakdong rivers so that we can check whether the cyanobacteria will decrease by 97% like the Geum and Yeongsan rivers just by opening the sluice gates, how many endangered species will return, and how the riverbed will recover over time. I want to get data,” he said.
Environmental groups said, “Even including sunk costs, dismantling the four major rivers is highly economical. The cost of the four major rivers project was 31 trillion won, and the benefits were only 6.6 trillion won, including 3.5 trillion won for hydrophilic benefits. In terms of cost-benefit ratio, it is a non-economic project that is only 0.21. “Is the Chosun Ilbo’s claim that facilities that incur costs without any benefits be maintained unconditionally?” he asked. “The European Environment Agency (EEA) is recommending removing obstacles blocking the river to restore the watershed to a nature-based solution (NBS) in the era of climate crisis, and the European Union (EU) aims to build 25,000 km of rivers by 2030. “We have adopted a strategy of free-flowing,” he added.
Environmental groups are concerned that “Korea’s environmental policy will retreat to anti-intellectualism by the Yun Seok-yeol government and the Chosun Ilbo, which intentionally and selectively distort the restoration of the four major rivers. It is enough for the Lee Myung-bak administration’s four major rivers project to take a step backwards in river policy,” he said. To the Chosun Ilbo, he said, “If you have at least the least self-esteem remaining as a journalist, you should put down your old regrets about the Four Major Rivers project and raise progressive and reasonable issues. How long will we deny the common sense that ‘stagnant water rots’?” he lamented. 2010 MBC Newstapa PD Choi Seung-ho (former MBC president), who has been reporting in depth the problems of the Four Rivers project since his PD days, pointed out on his Facebook page, “The Chosun Ilbo’s attitude toward the Four Rivers project is the representative of anti-intellectualism.”
