Waste Pollution
The Mekong Delta (MKD) is the largest delta in Vietnam, comprising 13 provinces and cities with an area of approximately 40,000 km² and a population of over 17 million people. This is the most important rice bowl, fruit basket, and aquaculture center of the country. However, in recent years, waste pollution in this region has become a serious environmental issue, directly threatening the ecosystem, public health, and the livelihoods of local people.
Current Status of Waste Pollution
According to statistics from the Ministry of Natural Resources and Environment, the entire Mekong Delta region generates about 3,200 – 3,500 tons of domestic waste daily, of which the collection rate only reaches about 50 – 60% in urban areas and below 20% in rural areas. The uncollected waste is often thrown directly into rivers, canals, and streams by residents or burned on-site, causing serious pollution to water and air sources.
Plastic waste is the most concerning type of waste. Plastic bags, plastic bottles, food packaging, and single-use plastic items overwhelm the intricate river and canal systems of the delta. Besides, waste from agricultural activities such as pesticide packaging, chemical fertilizers, and waste from the seafood processing industry also contribute to exacerbating the pollution. Many spontaneous landfills have cropped up along roadsides and canal banks without leachate treatment systems, causing pollutants to seep into the soil and groundwater.
Impacts on Nature and People
Regarding the natural environment, waste pollution has caused serious degradation of the characteristic river ecosystem of the Mekong Delta. Plastic waste decomposes into microplastics, accumulating in sediments and the food chain, threatening the region's biodiversity. Many aquatic species such as fish, shrimp, and crabs have significantly decreased in number due to the polluted water environment. The coastal mangrove forest ecosystem—which plays an important role in anti-erosion and coastal protection—is also heavily affected when waste accumulates in these areas, hindering the growth of mangrove trees and marine organisms.

For the people, waste pollution directly impacts health and daily life. Contaminated domestic water sources have led to an increase in the rate of digestive diseases, skin diseases, and pollution-related illnesses, especially among children and the elderly. The aquaculture industry—the main source of livelihood for millions of households—suffers heavy losses as water quality declines, leading to mass deaths of shrimp and fish, reduced productivity, and increased water treatment costs. Ecotourism, a potential economic sector of the region, is also negatively affected when the river landscape loses its aesthetic appeal due to waste.

Current Measures by Authorities and Residents
On the government side, provinces in the region have implemented many programs and policies aimed at minimizing waste pollution. Many localities have invested in building centralized waste treatment plants and expanding the waste collection network to rural areas. Authorities in provinces such as Can Tho, An Giang, and Kien Giang have issued regulations on waste classification at source and penalties for indiscriminate littering. Programs to propagate and raise community awareness about environmental protection are organized regularly through mass media and grassroots activities. Additionally, the government has approved the Sustainable Development Scheme for the Mekong Delta, in which environmental protection is one of the important pillars, with the goal of increasing the waste collection and treatment rate to 80 – 90% by 2030.

On the people's side, many communities have spontaneously organized trash collection activities in rivers, canals, and public areas. Movements such as "Against Plastic Waste" and "Say No to Plastic Bags" have received positive responses from residents in many localities. Several self-management models for environmental sanitation in hamlets and communes have proven effective, where people contribute funds for waste collection and commit to not discharging waste into the environment. Many farmers have also switched to clean agricultural production models, limiting the use of pesticides and collecting packaging after use according to regulations.
Conclusion
Waste pollution in the Mekong Delta is a complex issue that requires the cooperation of the government, businesses, and the community. Although many efforts have been made recently, the pollution situation has not been completely resolved due to limited financial resources, a lack of waste treatment infrastructure, and low awareness among a segment of the population. To protect this fertile delta for future generations, there is a need for synchronized, long-term, and more drastic solutions, including increasing investment in waste treatment infrastructure, developing a circular economy, promoting environmental education, and tightening penalties for polluting behaviors.
