Environmental impacts of water hyacinth

Native to South America, the water hyacinth has become a major weed in many countries in tropical and subtropical regions of the world. Once the water hyacinth covers the surface of a river or lake, it prevents sunlight from reaching native aquatic plants, and starves the water of oxygen, often killing fish and turtles, thus having huge negative impacts on nature. The International Union for Conservation of Nature (IUCN) lists the water hyacinth among “100 of the world's worst invasive alien species”, and it is a serious problem in Thailand.

Water hyacinth removal project by Canon Hi-tech Thailand staff

Canon Hi-tech Thailand works with the local community regarding flooding and droughts which happen in Thailand every year. Through such communication, we became aware of the serious environmental impact of water hyacinth. Accordingly, Canon Hi-tech Thailand started an initiative to remove water hyacinth together with local governments and communities. In 2016, we started this activity at two locations, Pho canal in Phra Nakhon Si Ayutthaya Province and Lam Takong River in Nakhon Ratchasima Province. Some 160 people from Canon and 40 people from local governments and communities participated, removing 59 tons of water hyacinth covering an area of 1,720 m2.

Canon Hi-tech (Thailand) promotes environmental conservation together with the local community. Under this policy, we regularly discuss local environmental issues with the local government and community. Upon becoming aware of the problem of water hyacinth, we started activities together with local governments and communities to remove water hyacinth. The members from Canon Hi-Tech (Thailand) participate voluntarily. We will continue to engage in local environmental conservation activities in the future.
