Vietnam's Water Pollution: Strategies And Solutions

Vietnam is facing a water crisis, with widespread water pollution threatening the health of its citizens and the productivity of key sectors. The country's rapid economic and demographic growth, industrialization, and urbanization have led to increased water demand and subsequent pollution. Inadequate environmental management, poor regulation, and irresponsible waste handling have resulted in the contamination of water sources, with untreated wastewater being released by industries and agricultural activities. Vietnam's geographical susceptibility to natural disasters such as typhoons, floods, and droughts further exacerbates water pollution and its impacts on public health and agricultural lands. The government has responded with short-term and long-term strategies, including the implementation of policies, programs, and international agreements, while also seeking to improve water infrastructure and conservation efforts.

Water pollution and public health

Vietnam's water crisis has had a significant impact on public health. The Ministry of Natural Resources and Environment estimates that up to 80% of diseases in the country are directly caused by water pollution. This includes waterborne illnesses such as cholera, typhoid, dysentery, and malaria, which have affected nearly six million citizens. Diarrhea, caused by poor water sanitation, is responsible for nearly 10% of deaths among children under five years old. The international community is particularly concerned about children, as dirty water affects their growth and development. UNICEF reports that the unhygienic practice of releasing excreta into the surroundings, still prevalent among over 9.5 million Vietnamese, further contaminates the water supply and poses health risks, especially to children with underdeveloped immune systems.

Water pollution in Vietnam is influenced by various factors, including rapid industrialization and urbanization, inadequate environmental management, and the improper use of water resources. The country's economic development has led to increased concentrations of toxins in the water, with surface water polluted by organic pollutants such as oil waste and solids, and untreated wastewater released by industries and agricultural activities. The geography of Vietnam also makes the country susceptible to natural disasters such as typhoons, storms, floods, and droughts, which further contribute to water pollution and waterborne diseases.

Agriculture, a key sector in Vietnam, has the largest impact on water resources. Water used for agriculture accounts for over 80% of total water production, with paddy rice being the primary crop. The modernization and industrialization of agricultural production have introduced new forms of pollution, such as wastewater from coffee-processing plants. Additionally, the overuse of fertilizers and pesticides contaminates both surface and groundwater. Fisheries, aquaculture, industries, and services also contribute to the increasing water demand.

To address these issues, the Vietnamese government has implemented policies and programs related to water resources management. The National Action Plans address areas such as water conservation and pollution reduction. The Vietnam Environment Administration (VEA), under the Ministry of Natural Resources and the Environment (MONRE), plays a crucial role in regulating and inspecting water-related issues. The Revised Law on Environmental Protection, which came into effect in January 2022, imposes responsibilities on corporations and gives communities a more prominent role in conservation. Vietnam has also committed to reducing emissions and addressing climate change, recognizing the economic costs of resource depletion and climate impacts.

Despite these efforts, challenges remain. There is a lack of physical infrastructure and financial capacity, leading to low utilization of water supply and uneven distribution. While access to safe water and sanitation has improved in recent decades, rural areas continue to face significant challenges, with only 39% of the rural population having access to clean water. The rural population often relies on groundwater, which is susceptible to contamination, such as arsenic in the Northern region of Vietnam. Furthermore, small enterprises in "craft villages" discharge untreated wastewater, and many industrial zones lack sustainable wastewater treatment systems.

Industrial and agricultural pollution

Vietnam's rapid economic and demographic growth has resulted in an increased demand for water, with water productivity currently sitting at about 12% of global benchmarks. This has led to the improper use of water resources, causing water shortages and pollution of the water environment.

Agriculture has the largest burden on water resources in Vietnam, with water used for agricultural purposes taking up over 80% of total water production. The overuse of fertilizers and pesticides in agriculture contaminates both surface and underground water. The modernization and industrialization of agricultural production have also caused new kinds of pollution, such as coffee-processing plants whose processing of beans for export demands a great amount of fresh water, later released as wastewater. Fisheries, aquaculture, and industries also contribute to the water demand increase.

The government of Vietnam is tackling water resources management issues by implementing policies and programs. Some of the challenges that still exist include improving access to clean water and sanitation for both urban and rural populations, and strengthening river basin management.

To address the issue of industrial pollution, the new law on PPPs, which came into effect on January 1, 2021, includes water infrastructure and will improve the regulatory framework for investments. This law will offer opportunities for more private investment in water infrastructure and requires owners of factories to use the best available technology to control pollution and limit environmental impacts.

Vietnam has also released National Action Plans to cope with increasing public interest in environmental quality. The plan covers areas related to air quality, water conservation, and plastic waste pollution. The Vietnam Environment Administration (VEA), under the Ministry of Natural Resources and the Environment (MONRE), is the main body that issues regulations, standards, and permits and performs inspections.

Water infrastructure and investment

Vietnam's water infrastructure and investment landscape is a complex one, with a range of challenges and achievements. The country has made significant strides in increasing access to water supply and sanitation over the years, with nearly universal metering and increased investment in wastewater treatment. However, it continues to face hurdles such as widespread water pollution, poor service quality, and low access to improved sanitation in rural areas.

One of the main challenges is the lack of physical infrastructure and financial capacity, which leads to low utilization of water supply and uneven distribution. This is particularly acute in rural areas, where only about 39% of the population has access to safe water and sanitation. The rural population often relies on groundwater, which can be contaminated with arsenic, as seen in the Northern region of Vietnam around Hanoi.

To address these issues, the Vietnamese government has implemented policies and programs related to water resources management. They have also released National Action Plans that address environmental quality, including water conservation and pollution reduction. International organizations like USAID have also provided donations and grants to support projects focused on providing clean water to educational institutions and communities in need.

Additionally, Vietnam has been integrating water issues into its development agenda, recognizing its importance alongside social equality, sustainable development, and environmental protection. The Law on Water Resources and the Revised Law on Environmental Protection reflect the government's efforts to strengthen regulations and community involvement in conservation. The new law on PPPs, effective from January 2021, includes water infrastructure and is expected to improve the regulatory framework for investments, potentially attracting more private investment in this sector.

Looking towards the future, Vietnam has proposed several solutions to address water resources development. These include formulating a framework of action for the entire country and each river basin, building reservoirs for the dry season, and systematically managing water resources exploitation and use. Vietnam's commitment to reducing emissions to Net Zero by 2050 also aligns with its efforts to tackle water pollution and protect its water resources.

Climate change and environmental protection

Vietnam is one of the fastest-growing per-capita greenhouse gas emitters in the world, with emissions multiplying fivefold in the last 20 years. The energy sector is the largest contributor to the country's GHG emissions, followed by agriculture, industrial processes, and waste.

The country's rapid economic and demographic growth have resulted in increased water demand, improper water resource use, water shortages, and water pollution. Agriculture, which uses over 80% of total water production, is the largest burden on water resources in Vietnam. The overuse of fertilizers and pesticides in agriculture contaminates both surface and underground water, and the modernization and industrialization of agricultural production have caused new kinds of pollution. For example, coffee-processing plants demand a great amount of freshwater, which is later released as wastewater. Fisheries, aquaculture, industries, and services also contribute to the increasing water demand.

Water resources have deteriorated due to deforestation, environmental pollution, and global climate change. Vietnam's geography and topography also make the country susceptible to natural hazards such as typhoons, storms, floods, and droughts, which further impact water quality and availability.

To address these issues, Vietnam has implemented several strategies and programmes for water resources planning and management. The government has released National Action Plans to cope with increasing public interest in environmental quality, covering areas such as air quality, water conservation, and plastic waste pollution. The Vietnam Environment Administration (VEA), under the Ministry of Natural Resources and the Environment (MONRE), is responsible for issuing regulations, standards, and permits, as well as performing inspections and education on national land laws and regulations.

At the 2021 United Nations Climate Change Conference (COP26), Vietnam committed to reducing emissions to net zero by 2050. To align with this target, the National Assembly passed the Revised Law on Environmental Protection, which gives communities a more prominent role in conservation and imposes responsibilities on corporations to control pollution and limit environmental impacts.

Water sanitation and access

Vietnam's water sanitation and access issues are complex and multifaceted, with a range of factors contributing to the problem. The country's rapid economic development and industrialization have led to increased water pollution, particularly in rivers and lakes surrounding industrial zones. This includes pollution from untreated wastewater released by industries and agriculture, as well as oil waste and solids. Vietnam's geography and topography also make the country susceptible to natural disasters such as typhoons, storms, floods, and droughts, which further compound water pollution issues.

The Vietnamese government has recognized the importance of addressing water sanitation and access and has implemented various policies and programs to tackle these issues. However, the country continues to face challenges such as inadequate physical infrastructure and financial capacity, leading to low utilization of water supply and uneven distribution of rainfall, resulting in water shortages.

Access to clean water and sanitation is particularly low in rural areas, with only about 39% of the rural population having access. In these areas, residents often rely on groundwater pumped from private tube wells, which can be contaminated with arsenic. The situation is better in urban areas, but still, only about 45% of industrial zones had wastewater treatment in 2010.

To address these issues, the government has prioritized water resources management and has released National Action Plans to improve environmental quality, including water conservation. International organizations like USAID have also provided donations and grants to support projects focused on providing clean water to communities and schools.

Vietnam has also committed to reducing greenhouse gas emissions and tackling climate change, which is expected to have a positive impact on water resources and the environment. The country's National Assembly passed the Revised Law on Environmental Protection in 2021, which gives communities a more prominent role in conservation and imposes responsibilities on corporations to control pollution and limit environmental impacts.
