Rice cultivation is a significant contributor to global greenhouse gas emissions, particularly methane (CH₄) and carbon dioxide (CO₂), due to anaerobic decomposition in flooded paddy fields. Addressing this challenge requires innovative and sustainable approaches to mitigate emissions while maintaining agricultural productivity. This research explores the integration of microalgae-based carbon sequestration within a controlled chamber system to evaluate its effectiveness in reducing the carbon footprint of rice cultivation. The study will employ a closed chamber experimental setup equipped with advanced gas sensors and real-time monitoring systems to quantify CH₄ and CO₂ emissions under different treatment conditions. Microalgae, known for their high photosynthetic efficiency and carbon fixation capabilities, will be introduced into the system to assess their potential in capturing and reducing carbon emissions. The experiment will compare emission levels from conventional rice farming practices with those treated using microalgae to determine the extent of mitigation achieved. Beyond emission reduction, this research aims to investigate the biochemical interactions between microalgae and soil microbiota, analyzing potential co-benefits such as enhanced soil health and improved nutrient cycling. The findings are expected to contribute to the development of a scalable, eco-friendly strategy for low-carbon rice production, aligning with global efforts in climate-smart agriculture and sustainable food systems. By demonstrating the feasibility of microalgae-based carbon sequestration in rice cultivation, this study has the potential to redefine conventional agricultural practices, supporting a carbon-neutral approach to food production while mitigating climate change impacts.
