Environmental Situation in Vietnam
On the situation of soil and water pollution in Vietnam
Thanks to coordinated efforts a positive development in environmental protection has taken place
in Vietnam during the past few years. The legal and policy framework has gradually been framed
and completed and now supports the environmental protection and socio-economic development
in Vietnam more effectively. The awareness of environmental protection of the public and
managers has been considerably raised, the levels of environmental pollution, degradation and
accidents have been gradually reduced - nature conservation has made a remarkable progress.
These achievements have contributed significantly to improving the living standard of people and
to ensuring a sustainable development of the country. However, the socio-economic development
has put considerable pressure on Vietnam´s environment. Despite the above mentioned
achievements the country’s environmental quality continues to degrade in many places, especially
in urban areas, coastal zones, river basins and craft villages.
Inland water environment: In general, water quality has remained relatively good in upstream
areas while most of the downstream areas are polluted and, in some cases, pollution has reached
serious levels. The sources of pollution are industrial and commercial waste water and domestic
sewage which, without prior treatment, is discharged directly into water bodies. In many places,
the water quality has been highly degraded; parameters such as BOD 5, COD and concentrations
of NH4, N and P have been found to be by many times higher than the permitted levels. Surface
water pollution in rivers, lakes, canals and cities continues to increase. In some areas, especially
in south-central Vietnam, the depletion of the water resources goes on.
Coastal water: Pollution from oil, heavy metals and suspended solids has been found to exceed
the permitted level in many coastal areas. Still, environmental sanitation on beaches has not been
improved which has a negative impact on the development of tourism. Aquaculture in mangrove
forest areas and on the sand has developed without due consideration of its adverse environmental
impacts on the marine and coastal environments.
Land environment: Land degradation appears to be a prevailing trend throughout the country as
a result of erosion, leaching, loss of organic material, droughts, floods, land slides and
subsidence, salt intrusion and alumination. Soil degradat...

impacts on the marine and coastal environments.
Land environment: Land degradation appears to be a prevailing trend throughout the country as
a result of erosion, leaching, loss of organic material, droughts, floods, land slides and
subsidence, salt intrusion and alumination. Soil degradation has exhausted many areas and even
led to desertification in some places. The over- and misuse of chemicals and pesticides in
agriculture pollute and degrade many areas nationwide.
Solid waste: Solid waste management in urban and industrial areas has been inefficient and
insufficient. Only about 70 per cent of all waste is collected mainly in central urban areas. In
many urban and industrial areas, hazardous waste is not separated and it is disposed in landfills
along with domestic waste. In most of the cities and industrial zones, landfill sites for solid waste
lack a correct sanitation or are poorly operated which has serious impacts on public life.
Water environment: The pollution of surface water and groundwater is becoming increasingly
serious, particularly in river basins, small rivers and canals in urban areas.
