Bhutan faces mounting pressure on its municipal solid waste (MSW) management systems. Its capital city, Thimphu, generates approximately 50 tonnes of MSW per day, of which roughly 30 tonnes per day is organic (wet) waste that is currently deposited at the Memelakha landfill — an ageing open-dumpsite already well beyond its intended lifespan. At the...

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。...

Presentation at the year-end project meeting : Research on Intangible Cultural Heritage and Climate Change in the Asia-Pacific Region, coordinated by International Research Centre for Intangible Cultural Heritage in the Asia-Pacific Region (IRCI)

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...

環境省業務「令和７年度途上国における適応M&Eツールの適応プロセス実装支援及び国際整合化検討業務」では、ユーザー対話型の適応のモニタリングと評価（M&E）ツール「Japan Adaptation Monitoring and Evaluation System」 （以下、「JAMES」）を開発途上国の諸都市における適応計画や防災計画等の気候変動適応推進プロセスに引き続き実装し、途上国の地域での適応プロセス推進を支援するとともに、国際援助機関や開発コンサルタント等が実施する支援事業とJAMESの連携可能性について検討を行った。併せて、2023年に国連気候変動枠組条約（UNFCCC）第28回締約国会議（COP28）で合意されたUAEフレームワークとの整合性を図りつつ、各国...

Through a study of Ra Province (northeast Viti Levu Island, Fiji) involving both archival research and community engagement, we highlighted a long history of Indigenous population mobility. Many coastal settlements have mostly undocumented histories of relocating inland due to shoreline retreat and land loss over recent decades. Studies of...

From "Islands of Excellence" to a "Sea of Change": How ASEAN's Secondary Cities are Localising the SDGs in the region As the ASEAN region rapidly urbanises, the focus often falls on its mega-cities. However, a quiet transformation is underway in the region’s secondary cities -- the agile urban centres that are proving to be fertile ground for...

This report provides a baseline assessment of Cambodia’s informal waste sector, with a focus on Phnom Penh and Battambang. Informal waste workers, including street pickers, door-to-door collectors, pickers at landfills and junkshop operators, play a critical yet undervalued role in the country’s waste management system. They are responsible for a...

The 'National Workshop on Enhancing the Capacity of the Informal Waste Recycling Sector Towards a Zero Waste Society' concluded with a plenary discussion on government support for informal sector integration, acknowledging the existing technical support provided by the Ministry of Environment and the potential for collaboration with the Ministry of...
