本研究は、南部アフリカ開発共同体（SADC）諸国における気候変動が環境劣化に与える影響を、1990～2024年のパネルデータを用いて分析。主成分分析で指標を構築し、固定効果モデル等で推定した結果、気候変動は環境と貿易開放度に有意に負の影響を与え、温室効果ガス排出による環境劣化がSADC地域の30%に及ぶことが示された。適応・緩和策と再生可能エネルギーへの政策統合が急務。
English
This study examines the effect of climate change on environmental degradation in SADC countries using panel data from 1990 to 2024. Principal component analysis constructs indices, and fixed-effects models reveal that climate change significantly negatively affects the environment and trade openness. Greenhouse gas emissions expose 30% of the region to degradation, threatening crop productivity. Integrated policies for adaptation, mitigation, and renewable energy are urgently needed.

日本のGX文脈において
本論文はSADC地域に焦点を当てており、日本のGX政策（SSBJや有報）への直接的な関連性は低い。しかし、気候変動の実証分析手法や政策統合の必要性は、日本の国際協力や途上国支援の文脈で参考になる可能性がある。
In the global GX context
This paper provides empirical evidence on climate change impacts in a developing region, contributing to the global understanding of climate-environment linkages. While not directly tied to TCFD/ISSB frameworks, it underscores the need for integrated climate policies, relevant for global discussions on adaptation and mitigation in vulnerable economies.
👥 読者別の含意
🔬研究者:Provides empirical evidence on climate change impacts in SADC using panel data and robust estimators, useful for researchers studying climate-economy linkages in developing regions.
🏛政策担当者:Highlights the urgency of integrated climate adaptation and renewable energy policies in SADC, offering insights for policymakers in developing regions.
📄 Abstract（原文）
The study investigated the effect of climate change on environmental degradation in the Southern African Development Community (SADC) countries. Using data sourced from the World Bank indicator from 1990 to 2024, the study constructed indices for climate change and environmental degradation using principal component analysis. The study employed Robust Standard Error Estimation in the Pooled Ordinary Least Squares and Fixed-Effects Panel models to examine the study objectives. However, for the sensitivity analysis, the study used a Driscoll-Kraay Standard Error (DKSE) and Panel-Corrected Standard Errors (PCSE) estimators to control for cross-sectional dependence and model heterogeneity. The results revealed that climate change significantly negatively affects the environment and trade openness. A variety of climate hazards critically expose 30% of the SADC region to environmental degradation driven by greenhouse gas emissions, and this may significantly reduce crop productivity without adaptation, especially for cereals. In conclusion, the SADC countries desperately need integrated policies and strategies that promote adaptation and mitigation of climate change, renewable energy, and reduced environmental pollution.
