Urban heat in rapidly growing megacities is spatially uneven, yet the relative influence of built form, socioeconomic activity and blue-green spatial configuration remains insufficiently resolved in cities of the Global South. This study examines neighbourhood-scale controls on land surface temperature (LST) in Delhi, India, using a single clear...

Padang City relies heavily on community-based waste banks (Bank Sampah) as decentralized units for waste segregation, recycling, and household engagement. These waste banks play a critical role by promoting waste segregation at source; providing economic incentives for households; acting as intermediaries between communities and recyclers. However...

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...

The Association of Southeast Asian Nations (ASEAN) has become one of the most important regions in the global climate debate because it combines rapid economic growth, rising energy demand, and high climate vulnerability. This regional context has become more urgent after the outcome of the first Global Stocktake (GST 1) adopted at CMA.5 in 2023...

Flood-dominated floodplains are undergoing rapid land-use and land-cover (LULC) change, with consequences for exposure, ecosystem condition, and local development planning. This study examines historical LULC change, transition intensity, trend-consistent land-use scenarios, and event-based flood exposure in Bongaigaon District, located in the...

Microplastic pollution in tropical urban rivers has become an increasing environmental concern due to rapid urbanization, inadequate waste management, and hydrological transport processes. This study investigated the occurrence, characteristics, and spatiotemporal distribution of microplastics in the Can Tho River, Vietnam, along an urban– peri...

There is a growing momentum regarding the necessity of youth engagement in environmental processes. A recent milestone is the resolution adopted at the 7th United Nations Environmental Assembly (UNEA-7) in December 2025, titled “Resolution on enhancing the meaningful participation of youth in Environmental Processes and on environmental education...

The Asia-Pacific region stands at a historic crossroads. Rapid economic growth and urbanization over recent decades have delivered major social gains, including higher living standards, reduced poverty and expanded access to education. Yet the resource intensive, linear production and consumption model that has underpinned this growth is now...

Achieving the Sustainable Development Goals (SDGs) in the Asia-Pacific region requires understanding the deeply interconnected nature of the triple planetary crisis: climate change, biodiversity loss and pollution, while advancing socioeconomic development. Progress depends not only on sectoral achievements, but on the ability of policymakers and...

The previous chapters underscored that addressing climate, biodiversity and pollution crises together can generate synergies and accelerate progress on the Sustainable Development Goals (SDGs). Implementing synergistic solutions, however, require a range of strategies and mechanisms that can break down silos and facilitate interactions across...
