Marine economy threatened by plastic waste pollution

Vietnam possesses over 1 million km² of marine area, three times its land area, with a coastline stretching 3,260 km and 2,770 offshore islands. The marine economy has long been a key driver of national growth, contributing significantly to tourism and employment .

However, in recent years, this economic sector has been seriously threatened by marine pollution, particularly plastic waste, which is becoming a major barrier to sustainable development.

1. Current State of Marine Pollution in Vietnam

Economic growth has led to a rapid increase in waste generation, especially plastic waste. Studies show that:

Plastic waste accounts for approximately 94% of collected solid waste in coastal and river areas
Vietnam ranks among the top countries contributing plastic waste to oceans, with 0.28–0.73 million tons annually
Many coastal areas and rivers are heavily polluted by untreated wastewater, oil spills, and domestic waste

This alarming situation is directly impacting marine ecosystems and coastal economies.

2. Impact on Marine Economy

Marine pollution is causing severe consequences:

Decline in marine resources

Coral reefs and ecosystems are degraded
Fish stocks are reduced due to pollution and habitat destruction

Tourism losses

Polluted beaches reduce attractiveness of destinations such as Phu Quoc, Nha Trang, and Vung Tau
Coastal tourism revenue is negatively affected

Impact on livelihoods

Aquaculture and fisheries suffer losses
Millions of workers depending on marine resources face income instability

Notably, the contribution of marine and coastal economy to Vietnam’s GDP has declined significantly over time .

3. Causes of Marine Pollution

Natural causes

Coastal erosion and sediment accumulation
Decomposition of marine organisms
Natural mineral dissolution

Human causes (main driver)

80% of marine waste originates from land-based activities
Domestic waste flowing through rivers into the sea
Industrial and agricultural wastewater not properly treated
Oil spills from fishing and shipping activities
Unsustainable fishing practices (explosives, chemicals)
Poor awareness in tourism and public behavior

4. Solutions to Protect the Marine Economy

To address this crisis, coordinated actions are required:

Policy and management

Enforce strict regulations on waste discharge
Ban destructive fishing methods
Strengthen monitoring of industrial wastewater

Infrastructure improvement

Invest in wastewater treatment systems
Improve coastal waste management systems

Community awareness

Promote environmental education
Encourage beach clean-up campaigns

Technology and equipment solutions

Use beach cleaning machines, street sweepers, and river waste collectors
Apply modern environmental cleaning technologies to improve efficiency

These solutions not only help reduce pollution but also support sustainable marine economic growth.

Conclusion

Marine pollution, especially plastic waste, is posing a serious threat to Vietnam’s marine economy. Without immediate and coordinated action, the long-term impacts on biodiversity, tourism, and livelihoods will continue to worsen. Sustainable solutions combining policy, technology, and community engagement are essential to protect the ocean and future economic development.
