VietNamNet Bridge – Chan May – Lang Co has been well known in Vietnam and in the world as one of the most beautiful bays with its untouched beauty and natural landscapes. However, scientists have warned that the sea area is facing the environmental damage.
The sea pollution has been warned by Dr Nguyen Duc Toan, Bui Quang Hat and Ly Viet Hung from the Environment Consultancy and Technology Center, who has completed the survey on the Chan May – Lang Co sea area in Thua Thien-Hue province. The survey is a part of the project on researching, assessing and forecasting the pollution that may cause the environmental damage on the territorial waters of Vietnam.
The scientists have found heavy metal elements in the sea water, mostly at the Lap An lagoon area, and partially in at the Chan May bay. The oil concentration on the Lang Co – Chan May sea area is between 0.02-0.12 mg/l, higher than the allowed level applied to beaches and aquaculture areas. Especially, the higher oil concentration of 0.08-0.12 mg/l was found on some areas of the entrance to the Lap An lagoon at the depth of 0-2 meters.
The survey has also found out that the heavy metal elements such as lead, zinc, copper, manganese have appeared which may cause pollution on some areas like the Chan May Tay cape (12-14m in depth), the North and the South East of Chan May Dong (8-11m and 17 - 21m in depth), the east of mountain Gion (15 - 19m in depth), and Lap An lagoon.
The location of the pollution factors can shows the causes of the pollution. On those areas, human activities are being carried out every day, such as the operation of ships, marine craft services, fisheries. The use of chemical substances to clean ships, the use of petrol and oil, together with many other activities have had big influences to the environment of the area.
It is expected that economic activities in the areas, including the natural resource exploitation, aquaculture, industries and tourism, would develop rapidly. This would make it easier to increase the concentration of heavy metal and oil in the sea water.
Scientists have also urged to take actions to protect the Chan May – Lang Co area in particular, and to conserve the sea in general, in order to retain the natural beauty. The overly high economic development would harm people themselves, because once the bay is getting polluted, it would not be able to attract tourists any more.
In fact, the government has been well aware of the necessity to protect the sea. It has laid out a lot of policies to ensure the sustainable development of aquaculture on sea areas.
In mid 2010, the Prime Minister approved the plan to set up marine protected area MPA by 2020. Under the MPA programming, by 2015, Vietnam would have 16 MPAs.
In the period from 2007 to 2011, with the support of the Danish government, the Ministry of Agriculture and Rural Development carried out the project on giving livelihood support to local residents at four MPAs of Cu Lao Cham in Quang Nam province, Phu Quoc in Kien Giang province, Nha Trang bay in Khanh Hoa and the Nui Chua National Park in Ninh Thuan province.
Local residents have been given assistance to take the jobs suitable to their capability, such as seafood processing, fish sauce making, or husbandry.
After three years of the project implementation, the income of households in Cu Lao Cham has been improved. The income from the sea decreased from 64.45 percent in 2006 to 43.4 percent in 2010, while the income from trade and services increased to 17.4 percent of the total income.
