Stubble burning in the Trans Indo-Gangetic Plain (IGP) significantly contributes to air pollution, posing severe threats to human health and the environment. This study investigates the interactions between stubble burning, vegetation productivity, atmospheric loading, and wind anomalies across the Trans Indo- Gangetic Plain using MODIS burned-area...

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...

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...

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...

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...

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。...

Agriculture in semi-arid regions is increasingly vulnerable to climate variability and land degradation, threatening rural livelihoods and food security. At the same time, the global transition toward clean energy, particularly solar power, offers synergistic opportunities to mitigate climate change while supporting sustainable rural development...

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...

Mining activities significantly alter environmental conditions by increasing atmospheric aerosol loads and degrading water quality. This study employs Google Earth Engine (GEE) to analyze spatiotemporal anomalies in Aerosol Optical Depth (AOD), PM₂.₅ concentrations, chlorophyll-a levels, and turbidity in Tonk, Rajasthan, between 2016 and 2022. Data...

Sustainable use of biodiversity in the Sundarbans- the world’s largest mangrove forest shared between Bangladesh and India has become increasingly complex due to rising climatic and livelihood pressures. There has been a general agreement that traditional ecological knowledge (TEK) is key to supporting ecosystem services (ES) and community...
