On September 10, 2010, Vice Minister, Dr Bui Ba Bong, launched the Ecological Engineering Initiative, locally called “Cong Nghe Sinh Thai” in My Tho City. (Read: Eco Eng initiative). This Initiative aims to increase local biodiversity and ecosystem services by increasing flora biodiversity of the bunds surrounding rice fields. Rice farm communities were encouraged to increase densities of nectar rich flowering plants as shown above. A few species of common flowers was recommended.
The ecological engineering concepts were introduced in local newspapers (Read: Ecol Eng concepts explained) and the idea began to catch on. Several local newspapers featured ecological engineering and Vietnam’s main English newspaper, Vietnam News, published an article on this. In November 2010, An Giang province held a “Farmers’ Day” to introduce ecological engineering and was captured in the news (Read: Farmers’ Day news report).
In Thoai Giang village, fields using ecological engineering growing the variety OM 4218 had yields of 6 tons ha-1 and reduced insecticide use by 3 sprays. In Binh Hoa village, ecological engineering fields growing varieties, OM 1490, OMCS 2000 yielded 5.8 tons ha-1 in yield and also reduced sprays by three. In both villages the yields in the ecological engineering fields were above average and used 3 insecticide sprays less.
