Landslides present a critical hazard in the Himalayas, where steep topography, intense rainfall, and tectonic activity converge to destabilize slopes. Accurate delineation of high-susceptibility zones is essential to safeguard lives, infrastructure, and ecosystems. Here, we construct a comprehensive Landslide Susceptibility Map (LSM) for...

The grand design has been formulated recently for the ‘Growth-oriented Carbon Pricing’ concept in Japan. The blended approach, combining voluntary participation of the businesses with phased regulatory enforcement, deserves attention due to its potential to serve as a model for other countries in Asia. This paper gives an overview of the latest...

The knowledge product “Vulnerability of Highland Agriculture: Current and Future Climate Change Scenarios – Insights from Nan Province, Thailand” assesses how climate change is affecting smallholder highland farming systems in northern Thailand, with a detailed case study from Bua Yai subdistrict in Nan Province. Using climate projections, crop...

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...

Climate Change Vulnerability Assessment in Highlands – A Guidance Manual (Knowledge Product 3 under ADB TA-9993 THA) provides a practical, step-by-step framework for designing and implementing climate change vulnerability assessments (VA) tailored specifically to highland contexts. Grounded in field testing in Thailand’s highlands, the manual...

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...

Agrivoltaics, which combines the use of land for both agriculture and photovoltaic energy production, is emerging as a promising solution to the land use conflicts between farming and renewable energy. By simul[1]taneously boosting crop yields, enhancing solar panel efficiency and revitalising rural incomes, agrivoltaics is attracting farmers and...

Toward a Sustainable and Equitable Future for Our Planet

Microplastic pollution poses a significant threat to marine ecosystems, with land-based activities being the primary source. Wastewater treatment plants (STPs) and river systems act as key pathways, concentrating and transporting these plastics from urban areas to the sea. This presentation establishes a direct link between these sources and their...
