Over the years, the Mekong Delta has fallen victim to drought and salinity invasion which cause great damages for the local people. However, there are some rays of hope. During the past five years, facing the shortage of freshwater in the dry season, some farmers in Dong Thap—a province of the Mekong River—have taken regulatory measures in agricultural production to adapt to climate change in a “nature-friendly” approach.

Many models of water-saving agricultural practices have been underway, contributing partly to reducing the volume of water used, greenhouse gas emissions and production costs in unfavorable weather conditions. Local farmers also practice alternate wetting and drying techniques, the use of in-field concrete irrigation systems, smart fertilizers, IoT (Internet of things) in irrigation pump system management.

This model was pioneered by My Dong 2 Agricultural Service Cooperative in Thap Muoi District of Dong Thap Province. According to Ngo Phuoc Dung, director of My Dong 2 Cooperative, to cultivate rice, farmers had to use a significant amount of water for irrigation. However, rice paddies do not have to be submerged in water all the time of the growth process. There are times, rice paddies can develop very well in a dry field. Therefore, applying alternate wetting and drying techniques and watering by concrete troughs may help save the volume of water used.

“Compared to the technique of flooded fields using pumped water, the new farming practice helps reduce 30% of water and also 20-30% of electricity costs. These figures represent not only economic benefit but also a message to the community that we farmers are making a change to be more responsible to the environment,” said Mr. Dung.

Aside from rice, water-saving models are also integrated in the cases of vegetables, flowers and fruit trees across the localities in Dong Thap. By the end of last year, the total area with the new economical irrigation system had reached 24,299 hectares versus 21,506 hectares in 2019. In addition, other agricultural models have been applied, such as net houses and smart water-saving irrigation systems along with training programs for farmers. From these State-supported models, quite a few farming households have taken in the integrated fish-rice or lotus-fish systems, which  yield a high economic efficiency, and, at the same time, use freshwater rationally.

During a recent meeting with leaders of Dong Thap Province discussing the impacts of climate change on agriculture in the region, Assoc. Prof. Le Anh Tuan, deputy director of the Institute for Climate Change of Can Tho University, stressed on the necessity of being “nature-friendly” in cultivation. “Climate change is inevitable and we need to come face to face with it,” said Mr. Tuan. “However, rather than seeing it as a confrontation, we should adapt ourselves to be more nature-friendly.”

According to Mr. Tuan, in the past, although climate change grew more extreme, the people in some provinces have come up with adaptive and effective agricultural practice models. For instance, the integrated rice-shrimp system in the coastal provinces, discharge dike system in Dong Thap to lure natural fish instead of building dikes for the third rice crop and the integrated lotus-fish or lotus-tourism systems. “To be harmonious with nature, people in the Mekong Delta have come up with new measures,” said Mr. Tuan. “The crucial point is we need to change our mindset about climate change to live in peace with nature.”

What’s more, experts say facing climate change which is ravaging the world, commodity production has to comply with environmental protection criteria, which is also one of the top binding regulations on imports under new-generation free trade agreements (FTA) singed by Vietnam.

That is how farmers in Dong Thap are going more “nature-friendly” to introduce their products to the world market.
