中国の335都市のパネルデータを用いて、農業保険がCO2、N2O、CH4の排出に与える因果的影響を分析。農業保険はCO2とN2Oの削減に有効だが、CH4には効果がなく、高温多湿地域ではむしろ排出を増加させるリスクがある。適応策と緩和策の間にトレードオフが存在することを示唆。
English
Using panel data from 335 Chinese cities from 2001-2022, this study employs an instrumental variable approach to causally estimate the impact of agricultural insurance on disaggregated GHG emissions. It finds agricultural insurance reduces CO2 and N2O emissions by reducing nitrogen fertilizer use and crop residue burning, but has neutral to positive effects on CH4 emissions, especially in hot and humid regions, revealing a risk of maladaptation.

日本のGX文脈において
中国の農業保険がGHG排出に与える影響を分析した本研究は、日本の農業政策や気候変動適応策にも示唆を与える。特に、水田からのメタン排出が主要課題である日本において、CH4の増加リスクは重要であり、適応策と緩和策のトレードオフを考慮した政策設計の必要性を強調している。
In the global GX context
This paper provides causal evidence on the climate mitigation co-benefits and trade-offs of agricultural insurance, a key adaptation strategy. It challenges the use of aggregated CO2-equivalent metrics that mask divergent impacts across GHGs. For global policymakers, it highlights the need for complementary regulations to prevent maladaptation, especially for CH4 emissions in vulnerable regions.
👥 読者別の含意
🔬研究者:This paper offers a rigorous causal framework for studying adaptation-mitigation interactions and demonstrates the importance of disaggregating GHG emissions by gas.
🏢実務担当者:Agricultural insurers and policymakers can use these findings to design insurance schemes incorporating environmental safeguards, particularly for CH4 emissions in humid regions.
🏛政策担当者:The results underscore the necessity of coupling agricultural insurance with regulation to avoid unintended increases in CH4 emissions, especially in climate-vulnerable zones.
📄 Abstract（原文）
Abstract BACKGROUND Agricultural insurance is rapidly expanding globally as a primary climate adaptation strategy. However, its implications for climate mitigation remain ambiguous. Shielding farmers from climate risks may inadvertently incentivize high‐emission farming practices. This study unravels this adaptation–mitigation nexus. We investigate the causal impact of agricultural insurance on disaggregated greenhouse gases (CO 2 , N 2 O, and CH 4 ) in China. To achieve this, we utilize a comprehensive panel dataset of 335 prefecture‐level cities from 2001 to 2022 and employ an instrumental variable approach. RESULTS Our empirical analysis reveals a striking asymmetry. Agricultural insurance acts as a potent mitigation tool for CO 2 and N 2 O. It achieves this primarily by reducing defensive nitrogen fertilization and discouraging crop residue burning. However, these environmental co‐benefits do not extend to CH 4 . Instead, insurance exhibits a neutral‐to‐positive effect on CH 4 emissions. Furthermore, we observe significant CH 4 emission increases in high‐temperature and high‐humidity regions, indicating a severe risk of maladaptation. CONCLUSION These findings challenge the prevailing reliance on aggregated CO 2 ‐equivalent metrics. Such single‐metric assessments completely mask these divergent trade‐offs. Ultimately, agricultural insurance effectively synergizes climate adaptation with CO 2 and N 2 O reduction. Nevertheless, policymakers must urgently design and implement complementary environmental regulations to prevent CH 4 emissions, particularly in climate‐vulnerable zones. © 2026 Society of Chemical Industry.
