Title: Putting vegetable floats on Thanh Cong Lake again.
By the grant of Toyota Environmental Activities Grant Program, ICA Japan in cooperation with the Association of Vegetable Rafts in Chiba Prefecture, 10 vegetable rafts were put on Thanh Cong lake in Hanoi in 2012. The Thang Cong lake was the project site that was contaminated with human sewage, dead fish and blue-green algae, and also many people would dump rubbish into the lake. Because of that, 10 vegetable rafts were put on the lake by the grant of Japan volunteer postal savings in 2008 in order to raise the environmental awareness of residents. Aquatic plants grown in rafts on the lake absorbed the polluted water. Therefore, they cleaned up the water. This project was a continuation of the previous project, and was intended primarily to transfer technology skills to local staff. Local materials were used, and then rafts were produced while teaching the local staff carefully. These Vietnamese built rafts were intended not inferior to ones made in Japan. In addition, the investigation of the possibility of using effective microorganisms to purify river, and environmental education for students attending elementary and junior high school near the lake were implemented.
