この研究は主要な米生産国における22年間のデータを用いて、米生産と温室効果ガス排出の関係を分析した。排出強度は全ての国で減少し、生産性向上が排出効率改善に寄与したことを示している。しかし、灌漑や施肥の最適化などの技術普及には国ごとにばらつきがある。
English
This study analyzes 22 years of data from major rice-producing countries, examining the relationship between rice production and greenhouse gas emissions. Emission intensity decreased in all countries, indicating improved production efficiency. However, uneven adoption of practices like optimized irrigation and fertilization limits progress at the country level.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
この論文は、米生産におけるGHG排出効率の国際的な傾向を示しており、日本の農業分野における持続可能な米生産政策（例：水田からのメタン削減）に示唆を与える。日本は主要生産国ではないが、技術普及の課題は共通する。
In the global GX context
This paper provides a global perspective on rice GHG intensity improvements, relevant for agricultural emissions reduction strategies under climate commitments (e.g., Paris Agreement). It highlights the role of efficiency gains in food production systems.
👥 読者別の含意
🔬研究者:Researchers can use the emission intensity trends and instability indices for further analysis of agricultural GHG efficiency.
🏢実務担当者:Practitioners in agribusiness can benchmark their emission efficiency against global trends to identify improvement areas.
🏛政策担当者:Policymakers can note the uneven adoption of efficient practices and design targeted incentives for sustainable rice production.
📄 Abstract（原文）
Aims: Rice is a staple food for a large proportion of the global population. Rice fields emit greenhouse gases, including CO₂, CH₄ and N₂O. The present study aimed to estimate the emission intensity, growth rate and instability index of these gases from rice fields. Place and Duration of Study: Secondary data were collected for 22 years, from 2000 to 2022, from FAOSTAT. The major rice-producing countries were considered for the study. Methodology: The analytical tools used in the study were emission intensity, compound annual growth rate and the Cuddy-Della Valle Instability Index. Results: The results showed that emission intensity decreased in all major rice-producing countries. Rice production increased substantially, whereas emissions from rice fields increased moderately, indicating an improvement in emission efficiency. In Vietnam and China, production increased moderately, while emissions declined in Vietnam and increased slightly in China. Conclusion: The results showed that global rice production increased significantly, while CO₂eq emissions increased modestly. This difference indicates improvements in production efficiency. Although rice systems have become more greenhouse gas efficient by delivering higher output with lower emissions per unit of production, uneven adoption of practices such as optimised irrigation and fertiliser scheduling may continue to limit progress at the country level.
