Water Pollution In Vietnam: Where Is It Worst?

Water pollution is a significant issue in Vietnam, with nearly 76% of the population living in rural areas where infrastructure is lacking. Untreated human and livestock waste, as well as industrial wastewater, are major contributors to the pollution of water sources such as rivers, lakes, and canals. Hanoi and Ho Chi Minh City have the highest levels of water pollution, with massive amounts of domestic wastewater discharged directly into the environment. The health consequences are dire, with nearly 80% of diseases in the country caused by polluted water, including cholera, typhoid, dysentery, and malaria. The Vietnamese government has recognised the urgency of the situation and is implementing policies and programs to tackle water resources management issues, with a focus on improving access to clean water and sanitation for all.

Water pollution from industrial and agricultural activities

Vietnam is one of the world's richest agricultural regions and a top producer and consumer of rice. Water used for agricultural purposes accounts for over 80% of total water production in the country. The primary crop is paddy rice, which takes up the majority of the total irrigated area. Fisheries, aquaculture, industries, and services also contribute to the increasing demand for water.

The modernization and industrialization of agricultural production have caused new kinds of pollution. For example, coffee-processing plants require a large amount of freshwater during the processing of beans for export, which is later released as wastewater. The overuse of fertilizers and pesticides in agriculture contaminates both surface and underground water.

Vietnam's rapid economic development has also impacted river water quality, with an increased concentration of various toxins in the water. Surface water in the rivers is locally polluted by organic pollutants such as oil waste and solids, as well as untreated wastewater released by industries.

The Vietnamese government has been tackling water resources management issues by implementing policies and programs. They have partnered with the World Bank to improve access to clean water and sanitation, and to reduce greenhouse gas emissions. However, challenges remain, especially in rural areas, where only 39% of the population has access to safe water and sanitation.

Poor water sanitation and public health

Vietnam is facing a water crisis, with a large portion of its population lacking access to clean water and basic sanitation. This is a significant issue for public health, as contaminated water can lead to various diseases and health issues. According to the Ministry of Natural Resources and Environment, almost 80% of the diseases in Vietnam are caused by polluted water.

The lack of access to clean water and sanitation disproportionately affects vulnerable groups, including children, pregnant women, and ethnic minorities. Millions of children in Vietnam are at risk due to inadequate water, sanitation, and hygiene (WASH) services and support, especially in ethnic group-populated and hard-to-reach areas. This lack of access contributes to high rates of diarrhea, pneumonia, and parasitic infections, as well as malnutrition and stunting. Additionally, nearly 40% of girls and parents in Vietnam lack the knowledge and skills to manage menstrual health, leading to shame and harassment that affects girls' education and mental health.

The Vietnamese government has made efforts to improve water supply and sanitation through various reforms and programs, in partnership with organizations like the World Bank and UNICEF. These efforts have yielded notable results, with access to clean water in rural areas increasing from 17% in 1993 to 51% in 2020. However, challenges remain, particularly in rural and disadvantaged areas.

Water pollution in Vietnam is caused by various factors, including untreated wastewater from industries and agriculture, as well as organic pollutants such as oil waste and solids. The country's geography and topography also make it susceptible to natural disasters such as typhoons, storms, floods, and droughts, which further contribute to water pollution and impact agricultural lands and livestock. Additionally, the intensive use of water for agriculture, fisheries, aquaculture, and other industries increases the demand for water and puts pressure on water resources.

To address these issues, innovative solutions and strong partnerships between public and private entities are necessary. Financial innovations, such as the World Bank's Emission Reduction-Linked Bond, can help mobilize private capital for sustainable water projects. Additionally, improving public participation and knowledge, as well as strengthening river basin management, are crucial steps towards ensuring access to clean water and improving public health in Vietnam.

Water scarcity and shortages

Vietnam is one of the richest agricultural regions in the world, with a population of over 86 million. The country has 2360 rivers, more than 10 km long, which should provide a copious supply of water. However, due to a lack of physical infrastructure and financial capacity, there is low utilisation of the supply, along with an uneven distribution of rainfall, resulting in water shortages throughout the country.

Water scarcity is a significant issue in Vietnam, especially in rural areas, where many farmlands are located. Over 13 million Vietnamese do not have sufficient access to clean water for their daily activities, including 2.5 million people in rural regions. The rural population has moved from using surface water from shallow dug wells to groundwater pumped from private tube wells. In the Northern region of Vietnam, around Hanoi, there is evidence of arsenic contamination in the drinking water, putting around 7 million people at severe risk of arsenic poisoning.

Agriculture accounts for over 70-80% of total water use in Vietnam and provides about one-third of the country's employment. However, farmers struggle with water scarcity, especially during long drought seasons, which are becoming more severe due to climate change. The increasing number of dams built upstream of the Mekong River and insufficient administrative intervention have also led to water contamination, imbalanced distribution, and salination.

The Vietnamese government has been working to address water resources management issues by implementing policies and programs. They have made notable progress in urban areas, where almost all residents have access to reliable water services. However, in rural areas, only about 44% of the population can access water from centralised supply systems, while the rest rely on unsafe water sources.

Climate change and environmental damage

Vietnam is one of the fastest-growing per-capita greenhouse gas emitters in the world. The energy sector is responsible for more than half of the country's GHG emissions, followed by agriculture, industrial processes, and waste. The country is highly vulnerable to climate change impacts, and its population and economy are at high risk.

The country's water resources are already under pressure, with demand continuing to increase and water productivity remaining low. Agriculture is the largest burden on water resources in Vietnam, with over 80% of total water production being used for agricultural purposes. Fisheries, aquaculture, industries, and services also contribute to the increasing demand for water.

Water pollution is a significant issue in Vietnam, with severe consequences for human health and the productivity of key sectors. Urban wastewater is the largest contributor to water pollution, while in rural areas, rising fertilizer and pesticide use affect water quality. River water quality has been impacted by rapid economic development, with increased concentrations of various toxins, including oil waste and solids. The country's geography also makes it susceptible to natural disasters such as typhoons, storms, floods, and droughts, which further contribute to water pollution and waterborne diseases.

The Vietnamese government has recognized the importance of addressing water pollution and environmental damage. They have implemented water supply and sanitation reforms and programs, resulting in improved access to clean water in rural areas. Additionally, the government has passed laws and regulations, such as the Revised Law on Environmental Protection, which impose responsibilities on corporations to control pollution and limit environmental impacts. International partnerships, such as with the World Bank, have also played a crucial role in providing access to clean water and sanitation.

Climate change is expected to exacerbate the challenges Vietnam faces regarding water resources. Severe and unpredictable weather patterns due to climate change will place greater stress on the country's water resources, especially during the dry season when water flows are lower. Vietnam's commitment to reducing emissions to Net Zero by 2050 demonstrates its increasing attention to climate change and the environment, recognizing the economic costs of resource depletion and climate impacts on trade and investment.

Government initiatives and international partnerships

Vietnam's government has been tackling water resources management issues by implementing policies and programs. The government has also been putting considerable effort into implementing water supply and sanitation reforms and programs, with access to clean water in rural areas improving from 17% in 1993 to 51% in 2020. However, there is still a long way to go, as each year in Vietnam, 9,000 people die and 250,000 more are hospitalized due to poor sanitation and water quality.

The government has also been encouraging the privatization of the water treatment sector and prioritizing water collection, drainage, and wastewater treatment. In 2021, Vietnam's National Assembly passed the Revised Law on Environmental Protection, which gives communities a more prominent role in conservation and imposes responsibilities on corporations. The law, which came into effect in January 2022, requires factory owners to use the best available technology to control pollution and limit environmental impacts. The government also released Decree 06 on January 7, 2022, providing regulations on reducing GHG emissions and protecting the ozone layer.

The Ministry of Natural Resources and Environment (MONRE) is the main body in the Vietnamese government responsible for issuing regulations, standards, and permits, as well as performing inspections related to water resource management. MONRE has also been taking the lead in implementing measures on international environmental issues such as greenhouse gas reduction and the Stockholm Convention. The Vietnam Environment Administration (VEA), under MONRE, is responsible for planning the use of national land and is also in charge of education and awareness of national land laws and regulations.

International partnerships have played a crucial role in Vietnam's efforts to improve water quality. The World Bank has partnered with the Vietnamese government to improve access to clean water and sanitation. In 2023, the World Bank issued a $50 million Emission Reduction-Linked Bond to finance a water purifier project in Vietnam, which aims to provide millions with safe drinking water while reducing greenhouse gas emissions. Additionally, countries such as Japan, Denmark, Finland, Holland, Australia, Germany, and France have provided government grants to finance feasibility studies and master plans for environmental improvements and pollution prevention in Vietnam. These countries often have a competitive advantage in winning design and engineering contracts.
