Vietnam’s $3 Billion Annual Crop Losses Due to Rising Saltwater Levels
Vietnam is facing a significant challenge with nearly $3 billion in crop losses annually as a result of increasing saltwater intrusion into its arable land. This issue was highlighted in a recent report by state media, citing new research that sheds light on the alarming impact of rising saltwater levels on the country’s agricultural sector.
The Mekong Delta region, often referred to as “Vietnam’s rice bowl” for its crucial role in providing food and livelihoods for millions of people, is expected to bear the brunt of these crop losses. The region is particularly vulnerable to saltwater intrusion, which is exacerbated by factors such as rising sea levels, droughts, tidal fluctuations, and a lack of upstream freshwater.
Impacts on Vietnam’s Agricultural Sector
The damage caused by saltwater intrusion is projected to be substantial, with estimates suggesting that crop losses could amount to a staggering 70 trillion dong, equivalent to $2.94 billion. According to research conducted by the Water Resources Science Institute under Vietnam’s environment ministry, the southernmost Ca Mau province is anticipated to suffer the most significant losses, estimated at $665 million. Additionally, Ben Tre province could face losses of around $472 million.

The research findings indicate that fruit trees, crops, rice, and the fisheries industry are among the sectors most affected by saltwater intrusion in the Mekong Delta. Fruit trees account for 29 percent of the damage, while crops and rice contribute 27 percent and nearly 14 percent, respectively. The fisheries industry, a vital component of the region’s economy, is projected to incur losses of more than 21,000 billion dong ($840 million).
Future Projections and Climate Change Impacts
The study warns that the situation is likely to worsen in the future, with projected losses exceeding $3.1 billion. Factors such as climate change, including rising sea levels and changing weather patterns, are expected to further exacerbate saltwater intrusion in the region, posing a significant threat to Vietnam’s agricultural sector and food security.
Recent warnings from the Department of Water Resources indicate that saline intrusion could affect approximately 80,000 hectares of rice and fruit farms in the Mekong Delta. The region experienced higher-than-average salt intrusion between 2023-2024, as reported by the National Center for Hydro-Meteorological Forecasting. The prolonged heatwave in February led to drought conditions in several areas and decreased water levels in the region’s canals, compounding the challenges faced by farmers and communities in the delta.
Addressing the Challenges and Ensuring Sustainability
In light of the escalating threat posed by saltwater intrusion and its detrimental impact on Vietnam’s agricultural sector, urgent action is needed to address the challenges and ensure the sustainability of food production in the Mekong Delta. This necessitates a multi-faceted approach that includes:
1. **Enhanced Water Resource Management:** Implementing effective water resource management strategies, such as building reservoirs, water retention systems, and irrigation infrastructure, to mitigate the effects of saltwater intrusion and ensure adequate freshwater supply for agriculture.
2. **Promoting Climate-Resilient Agriculture:** Encouraging the adoption of climate-resilient agricultural practices, such as drought-resistant crop varieties, efficient water usage techniques, and soil conservation methods, to enhance the resilience of farmers and mitigate the impacts of climate change on crop production.
3. **Investing in Research and Innovation:** Supporting research and innovation in agriculture, including the development of salt-tolerant crop varieties, sustainable farming techniques, and climate-smart technologies, to equip farmers with the tools and knowledge needed to adapt to changing environmental conditions.
4. **Collaborative Efforts and Policy Support:** Fostering collaboration between government agencies, research institutions, non-governmental organizations, and local communities to develop comprehensive policies and initiatives aimed at addressing saltwater intrusion, enhancing food security, and promoting sustainable agriculture in the Mekong Delta.
By implementing these measures and prioritizing sustainable agricultural practices, Vietnam can work towards mitigating the impact of saltwater intrusion, safeguarding its agricultural sector, and ensuring the long-term food security and livelihoods of millions of people who depend on the fertile lands of the Mekong Delta.

Saltwater intrusion
Saltwater intrusion is the movement of saline water into freshwater aquifers, which can lead to groundwater quality degradation, including drinking water sources, and other consequences. Saltwater intrusion can naturally occur in coastal aquifers, owing to the hydraulic connection between groundwater and seawater. Because saline water has a higher mineral content...
