Highland regions in Thailand are increasingly vulnerable to climate change due to rapid land-use transitions, environmental degradation, and shifting socio-economic conditions. This Discussion Papaer examines the drivers and dimensions of vulnerability in the Thai highlands, with particular attention to the expansion of maize cultivation and...

Methane is a potent, short-lived climate pollutant responsible for nearly 0.5°C of global temperature rise. Though it remains in the atmosphere for about 12 years, its climate impact is 86 times stronger than carbon dioxide over 20 years, making methane mitigation one of the most effective strategies for tackling climate change. The waste sector...

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...

While the initiative successfully digitised thousands of...

Refuse-Derived Fuel (RDF) is gaining popularity in Indonesia as a promising solution for processing large volumes of municipal solid waste (MSW), extending landfill lifespans, and facilitating both material and thermal recycling. The quantity and quality of RDF are critically dependent on the input waste composition and the selection of materials...

Highland communities are facing numerous challenges that heighten their susceptibility to climate change, particularly because of rapid alterations in land use and land cover, which in turn affect local ecosystems. In the absence of non-governmental organizations and other non-state entities, local governments assume a crucial role in enhancing...
