東南アジア地域における急速な都市化と消費拡大に伴い、プラスチック廃棄物の発生量が急増し、プラスチック汚染が特に深刻な課題となっている。ASEAN諸国では、使い捨てプラスチックの禁止、拡大生産者責任（EPR）制度、普及啓発キャンペーンなど、さまざまな対策が進められている。しかし、これらの対策だけでは、根強く定着した消費行動を変えるのは難しい。 利用制限や普及啓発だけで十分な効果が得られないような課題に対し、行動科学は有効な補完的アプローチとなる。Behaviour-Centred （行動に関する理解に基づく、行動に焦点を当てた）アプローチを取り入れることで、単なる情報提供や経済的インセンティブに頼るのではなく、「意図と行動のギャップ」を埋め、持続可能な行動変容を促すことができる。...

Using behavioral insights to increase reusable water bottle use Nopa Move’s Smart Bottle Network, with support from the Economic Research Institute for ASEAN and East Asia (ERIA), Institute for Global Environmental Strategies (IGES), and Rare, addressed single-use plastic waste in Ho Chi Minh City’s commuter coffee culture, where disposables...

Changing the local reuse economy with behavioral science The Rent Your Cup initiative in Lao PDR, led by Econox with support from Economic Research Institute for ASEAN and East Asia (ERIA), Institute for Global Environmental Strategies (IGES), and Rare, addressed the growing problem of single-use plastic waste driven by expanding café culture and...

Using behavioral science to reduce plastic waste on the UP Diliman campus The University of Philippines Diliman (UP Diliman) initiative, led by UP Diliman with support from the Economic Research Institute for ASEAN and East Asia (ERIA), Institute for Global Environmental Strategies (IGES), and Rare, tackled plastic waste generated by a dense campus...

Plastic pollution is a growing challenge in Southeast Asia, where rapid urbanisation and rising consumption are driving sharp increases in plastic waste. While traditional regulations such as plastic bans and information campaigns are important, they often fail to shift deeply ingrained consumption and waste management habits on their own. This new...

APCSプロジェクトの過去3年間にわたる活動および成果を総括する場となった本シンポジウムでは、気候安全保障が抱える課題と機会について議論し、アジア太平洋地域の地政学的状況の変化の中で、気候安全保障が引き続き持つ意義について検討した。さらに、今後刊行予定の「APCS政策レポート」の紹介を通じて、本プロジェクトから得られた知見や洞察を、国内外の研究者、関連する政策立案者、および気候安全保障分野に関心を持つステークホルダーに広め、批判的に検討する場ともなった。

This symposium discussed the challenges and opportunities of climate security and examined its continued relevance under a shifting geopolitical landscape in the Asia-Pacific region. The event presented an opportunity to take stock of the activities and achievements of the Asia-Pacific Climate Security (APCS) project conducted by IGES over the past...

This paper examines the complex relationship between climate change and food security in the Asia-Pacific region. It demonstrates how climate change disrupts food systems through impacts on crop yields, fisheries, and supply chains, while interacting with socio-economic inequalities, governance failures, and competing resource demands to produce...

While food security is conventionally defined by four pillars—availability, access, utilisation, and stability—this apolitical framing overlooks underlying economic and political processes shaping food insecurity and constraining the agency of food producers. In doing so, it also overlooks the structural threats to human security. Considering the...

This presentation outlines an initiative applying behavioral insights (BI) to reduce single-use plastics (SUPs) across the Asia-Pacific region. Phase I (2022-2024) implemented pilot projects in Indonesia, Thailand, Vietnam, and the Philippines. Departing from traditional "rational choice" theories, the project utilized the "Levers of Behaviour...
