In southern Vietnam, farmer Vo Van Van is experimenting with innovative rice cultivation techniques, including less water usage and drone-assisted fertilization, in an effort to reduce methane emissions from rice paddies, which are a significant contributor to global warming. These techniques, supported by the Loc Troi Group, a large rice exporter, include alternate wetting and drying methods that use less water and organic fertilizer, and the collection of rice stubble for use in livestock feed and straw mushroom cultivation, thereby eliminating the need for burning. These practices not only help reduce methane emissions but also lower costs for farmers and offer a higher selling price for the organic rice produced. Vietnam, the world's third-largest rice exporter, is not only adopting these practices on a small scale but also aims to expand them across 300,000 hectares by 2030, with the support of the World Bank and other organizations, in an effort to mitigate climate change impacts on the Mekong Delta. The article highlights the need for more countries to adopt similar practices and discusses the potential of diversifying rice varieties to enhance resilience to climate change.
