Water hyacinths lead to Thua Thien-Hue’s river pollution
THUA THIEN-HUE — Water hyacinths bloom in the rivers and channel systems of Thua Thien-Hue Province, effecting the flows and polluting the water source of countless residents living along the rivers, especially in Phu Vang and Huong Thuy districts.
The province has invested about VND700 million (US$45,000), devoted thousands of working days and enlisted the close co-operation of all administrative levels from districts to communes to help fish water hyacinths from the waterways over the past month.
So far, over 430,000sq.m of water hyacinths have been fished out in the province helping the flows of river systems such as Bach Yen, Ngu Ha, An Cuu (Hue city), as well as channels including Moc Han, Cau Long (Phu Vang, Huong Thuy districts) and Sia (Quang Dien).
The water hyacinths are blooming more this year than in previous years because waste is thrown into rivers and channels, leading to the pollution of the water and creating a favourable environment for water hyacinths to bloom, said Ho Dang Vang, director of Thua Thien-Hue Service of Agriculture and Rural Development. Due to an increase in household prosperity, chemical fertilisers are more and more common. Water hyacinths are no longer the main ingredient in green manure or cattle-feed and chicken-feed.
Province officials are canvassing households to protect the environment and simultaneously develop food and fertiliser processing practices to better serve farming and breeding. —VNS
