Amidst the global challenge of climate change, agricultural regions like Vietnam’s Mekong Delta stand at the intersection of high productivity and significant vulnerability. The delta, home to over 18 million people and contributing more than 50% of Vietnam’s rice production, plays a vital role in ensuring food security across Asia and beyond. However, rising sea levels, excessive groundwater extraction, and saltwater intrusion threaten its survival. In response, a coalition of Vietnamese and Dutch experts have established the Mekong Salt Lab, dedicated to helping farmers in the Tra Vinh Province adapt to increasing droughts and salinization. Funded by Partners of Waters, we shed light on this ongoing innovation through a series of interviews. In our first episode, Gregor Van Essen and Bich Tran (Bica) update us on the current challenges and forthcoming steps.

About Salt Lab

Salt Lab addresses the impact of saline intrusion on farmers’ livelihoods in Tra Vinh Province, Vietnam. The project tackles issues such as reduced crop and fish yields, scarcity of fresh water for irrigation and household use, and the socio-economic consequences of salinity. It provides practical solutions and training through a Centre of Expertise, such as blended learning platforms, hydroponics, water treatment, and constructed wetlands. Adopting Farmer-to-Farmer and Public-Private Partnership models, Salt Lab will initially implement and integrate seven promising adaptive and scalable interventions, enhancing resilience and sustainable agriculture in the Mekong Delta. These are the 7 solutions part of the pilot project:

  • Hydroponics: an open-field, low cost, and low-tech hydroponics system designed to grow crops in saline-affected areas.
  • Freshwater Collection and Retention: techniques such as water bags, retention ponds, and lining irrigation canals to maximise availability of freshwater
  • Water and Wastewater Treatment: innovative nanofiltration methods using hollow fibre (HF) membrane modules for treating polluted water sources efficiently and sustainably.
  • Constructed Wetlands: artificial wetlands at the farm level to retain fresh water, treat polluted water, and promote groundwater infiltration.
  • Salinity Data Farming Platform & App: a unique platform and mobile app that provides real-time salinity data, helping farmers make informed decisions.
  • Asia Raincraft: a serious gaming-based approach for community and stakeholder participation, fostering collaboration in addressing water and climate adaptation.
  • Salinity Blended Learning Programme: equips farmers with practical knowledge about salinity and how they can respond or adapt to it.

Project team

The Mekong Salt Lab project is managed by a team of four members, including Gregor van Essen from The Water Agency and Bich Tran from Tra Vinh University, Vietnam. Gregor, as project director, oversees strategic operations and engages with key stakeholders like Partners for Water and the Dutch embassy. With over two decades of experience in the Mekong Delta, Bica, responsible for operational models, is deeply committed to enhancing farmers’ livelihoods in the region.

Empowering farmers: the crucial role of Mekong Salt Lab

Vietnam faces severe water deficits, worsened by intense droughts. During extreme dry seasons, the lack of freshwater forces many farmers to abandon their crops, a situation worsened by rising salinity levels. Farmers often lack the practical support needed to combat salinization. While they witness the negative impacts, such as failed crops, they lack the data, tools, and knowledge to respond effectively:

  • Practical salinity data: Farmers need timely and useful data to assess the quality of various water sources and monitor changes in salinity levels over time.
  • Practical knowledge and tools: Farmers require practical knowledge and tools to adapt to salinity, including methods for freshwater retention, water treatment, and the cultivation of salt-tolerant crops.
  • Actionable and affordable support: Farmers need support and solutions that are both practical and affordable.

The services of Mekong Salt Lab are specifically targeting these gaps and the urgency of doing this for farmers cannot be overstated. Gregor emphasises its significance, stating, “For Mekong farmers, this project is not a nice-to-have; it is a matter of survival.” Despite the challenges, engaging local farmers in education and changing their practices is a formidable task. Bica underscores the importance of patience and cultural understanding, noting, “We must listen to local farmers and adjust our model to meet their needs.” Experimenting and upscaling present significant challenges during the initial phase, making the role of the Salt Lab crucial in addressing these issues and ensuring the sustainability of local agriculture.

Consortium Partners

The Mekong Salt Lab project thrives through the collaboration of a diverse consortium of Dutch and Vietnamese partners, including The Water Agency, Tra Vinh University, Kim Delta, The Salt Doctors, Saxion University, HZ University, SkillEd, and Acacia Water. Each partner brings specialised expertise in areas such as hydroponics, freshwater retention, saline agriculture, soil management, blended learning, stakeholder engagement, aquaculture, and wastewater treatment. Co-funded by the Partners for Water programme, this consortium benefits from regular guidance and oversight. As Gregor stated, “The collaboration with Partners for Water goes beyond funding. They connect us with other initiatives and partners in the Mekong Delta that can strengthen our project” This partnership aims to create sustainable water solutions tailored to the Mekong Delta’s needs.

Collaborating with local partners

Working closely with local partners is indispensable for the success of the Mekong Salt Lab project. Through comprehensive needs and gap analyses, the team ensures that their solutions align with local realities. “We’ve consulted local authorities and farmers extensively during the proposal phase to understand their needs and explore potential solutions,” explains Bica. Engaging influential “champion farmers” has proven pivotal. “We’ve carefully selected farmers who can effectively represent the issues we’re addressing and actively contribute to the project,” notes Bica.

Currently, two champion farmers are piloting integrated systems that include water collection and retention for agricultural activities, water treatment for household use, vertical hydroponics, and deep-water hydroponics to address salinity and water scarcity. The challenge lies in adapting these Dutch systems to the local context and ensuring the farmers learn how to operate them effectively. “We need to educate these farmers thoroughly while determining the best practices for them. This will help us develop a general approach for broader implementation of these systems”.

The interest among local farmers and government officials is evident. The local government, having already visited three times to assess the project’s progress, underscores their commitment and enthusiasm. The governments of the neighbouring provinces of Soc Trang and Ben Tre have also shown interest. By leveraging local expertise and fostering continuous dialogue, the project is well-positioned to achieve long-term success and make a significant impact on the community.

In the field and next steps

Currently the project is in its first phase, in which innovative solutions are being implemented at two champion farms and soon to be expanded. “With these farmers, we set up a model with hydroponics for vegetable planting. The deep water culture helps save water for farmers. The next step is integrating solutions effectively,” Bica says. Looking ahead, Gregor envisions broader success, stating, “We want the Mekong Salt Lab to become a one-stop support centre for farmers. Farmers can come to us for practical advice, solutions, and training.” The ultimate measure of success lies in the project’s ability to sustainably improve farming yields and enhance farmers’ livelihoods.

This May, Tamar Meibergen joined Partners for Water as a Programme Advisor

She will work on various projects, such as the Vietnam programme, the subsidy scheme, the monitoring and evaluation framework and an event about Nature-based Solutions. In her spare time, she is also all about water sailing competitively on an all-female team. Nice to meet you, Tamar!

International Ambition

‘While I was studying, water was always the focal point. First with my bachelors in Social Geography and Planning in Utrecht and then later with my masters in Environmental Geography in Amsterdam.’ As a part of her studies, Tamar did an internship at the NGO Wetlands International in Mali. ‘I worked on many interesting projects there, like a flood warning system for illiterate farmers and figuring out how to make gold extraction sustainable.’ After her studies, Tamar worked for 2,5 years as a Water and Climate Consultant at TwynstraGudde. ‘Although I learned a lot, I also realised that I want to invest more time in implementing projects internationally, while working together with all kinds of different people. So, when the opportunity arose to work with Partners for Water I decided to go for it.’

Innovation and Experimenting

Tamar believes her consultancy experience will prove to come in handy at Partners for Water. ‘Although I have only just started, I can already tell that there is a lot innovation and experimenting here. If you see an opportunity there is room to go for it. Applying a proactive approach is something I learned both at TwynstraGudde and while doing a ‘Inclusieve Groene Groei’ (Inclusive Green Growth) internship at the Ministry of Foreign Affairs. These work experiences also taught me how to develop strong networks. It will be interesting to be on ‘the other side’ as now I’ll be working with consultants instead of being one myself. I think knowing both perspectives will help me too.’

Vietnam Experience

‘I’ll be working on several topics over the next few months. For example, I will spend time on our Vietnam programme while the designated Programme Advisor is away. Luckily, I already have some prior knowledge of Vietnam. I was there for my master thesis, which was about the export of Dutch water expertise and how trade missions contribute to them. I will also work on our subsidy scheme as well as our monitoring and evaluation framework, which will helps us see the results of our work more tangibly. Lastly, we will organise a Nature-based Solutions event when the World Bank and Asion Development Bank delegates visit in June.

Meaningful Cooperation

Tamar appreciates the changes made in the way the Dutch water sector works with international partners. ‘We used to present a solution without really consulting with our counterparts. Nowadays, there is meaningful cooperation in the whole process making use of local knowledge.’ Water is not only important to Tamar in her professional life, but also in her private life. That is why she devotes a lot of time to competitive sailing. ‘I’ve been on the water since I was young. The team I’m involved in is all-female,  which is pretty unique in the competitions we enter. When I’m sailing, I not only see trash in the water, but also the daily problems that are connected to water management. This make it all the more motivating to make the most of my time at Partners for Water.’
