(VAN) If organic rice farming methods are implemented simultaneously and optimally in the Mekong Delta, a massive reduction in annual emissions is within sight.

Rice cultivation in the natural direction is an inevitable trend. It brings many sustainable benefits, such as achieving economic goals and protecting the environment. The aim is to ensure safety and protect the future of the Mekong Delta region in the context of increasingly complex developments of climate change.

Professor Andy Large, Project Director of Newcastle University (UK), recently commented on the research results of the three main components of the project "Research on the Mekong Delta phase 2019 - 2024" (Living Deltas Hub). "Developing agriculture in a natural direction is not only about economic benefits but it also carries strong historical, social and local cultural elements, the present and future generations of the Mekong Delta in accordance with the spirit of Resolution 120 on sustainable development of the Mekong Delta in adaptation to climate change".

The Mekong Delta is facing many problems, primarily unsustainable development and impacts from hydropower projects upstream. Along with that, the Mekong Delta has to deal with urgent challenges from climate change as it results in changes in rainfall patterns as well as increased frequency of drought and saltwater intrusion, thus affecting development prospects as well as the long-term livelihoods of the people.

Professor Andy Large believes that responding to climate change through natural solutions is an urgent requirement. As a matter of fact, localities in the Mekong Delta have been implementing many agricultural cultivation solutions in the natural direction such as the Scheme for sustainable development of 1 million ha of high-quality and low-emission rice cultivation associated with green growth in the Mekong Delta by 2030.

Farmers also utilize smart rice cultivation models adaptive to climate change, models that promote the use of organic fertilizers and biological pesticides, circular livestock farming models, economy structures under the forest canopy, rice - shrimp models, and the list goes on.

Dr. Nguyen Van Kien, Project Leader of An Giang University, shares a similar view. The ecological and organic rice farming model is considered a unique form of natural cultivation within the Mekong Delta region, helping farmers adapt in harmony with nature and set up control following the laws of nature to bring benefits to the people and protect the ecological environment.

“The foundation for promoting the development of organic agriculture in general and organic rice in particular is already there, not to mention this is even an inevitable trend. However, agroproduction in the natural direction still shows little value and farmers have not gained much benefit. On the other hand, not all models in the natural direction are highly effective. Therefore, it is essential to build small ‘prototype’ models to demonstrate effectiveness, then expand, combine with regional integration, consumption linkages and market development to maximize efficiency and create a culture of agriculture in harmony with nature among the people,” said Dr. Nguyen Van Kien.

The Ministry of Agriculture and Rural Development is implementing a Scheme for sustainable development of 1 million ha of high-quality, low-emission rice cultivation associated with green growth in the Mekong Delta. Implementing the scheme means moving towards organic rice production by applying production techniques such as integrated pest management (IPM), alternate wetting and drying (AWD), “1 must, 5 reductions” and “3 reductions, 3 increases”.

If organic farming practices are implemented simultaneously and optimally across the entire 1.9 million ha of rice fields, by 2030 emissions in the Mekong Delta will be reduced by nearly 11 million tons of CO2 per year. Reusing 70% of straw for other uses will reduce greenhouse gas emissions by approximately 50% in comparison to just burning straw in the fields.

The Mekong Delta can also reduce 12 - 23 tons of CO2 by promoting climate-adaptive cultivation methods and good agricultural practices, replacing inefficient rice land with climate-smart farming systems, reducing post-harvest losses, and better managing agricultural by-products specifically straw.
