Rice cultivation is a staple of global agriculture, supporting the livelihoods of millions, but it is also a significant source of greenhouse gas (GHG) emissions, particularly methane and nitrous oxide. These emissions contribute to climate change, necessitating the development of effective mitigation strategies. This study explores the mechanisms of GHG emissions from rice paddies, including methane production pathways and the factors influencing nitrous oxide emissions. Various strategies for reducing emissions are analyzed, such as water management techniques like alternate wetting and drying (AWD), soil fertility management through integrated nutrient approaches, and crop management practices that enhance sustainability. Furthermore, the role of rice paddies in carbon sequestration is examined, alongside policy frameworks and incentive programs to support emission reduction. A case study highlights successful implementations of these strategies and the associated outcomes. The study concludes with a discussion on the challenges to widespread adoption and the need for future research to enhance both mitigation and climate resilience in rice production systems.
