Air pollution is becoming a prominent social problem in fast-growing Asian economies. Taking the Bangkok Metropolitan Region (BMR) as a case, we conducted an observational study of fine particulate matter (PM2.5) and acid deposition, consisting of their continuous monitoring at two sites. To find the major contributing sources of PM2.5, the PM composition data were analyzed by a receptor modeling approach while the pollution load from BMR sources to the air was characterized by an emission inven

Climate change may intensify tropical cyclone activities and amplify their negative economic effects. We simulated the direct economic impact of tropical cyclones enhanced by climate change with the integrated assessment model Climate Framework for Uncertainty, Negotiation and Distribution (FUND), Version 3.4. The results show that in the basic case (parameter levels based on intermediate estimates), the direct economic damage caused by tropical cyclones ascribed to the effect of climate change

Extratropical cyclones have attracted some attention in climate policy circles as a possible significant damage factor of climate change. This study conducts an assessment of economic impacts of increased storm activities under climate change with the integrated assessment model FUND 3.5. In the base case, the direct economic damage of enhanced storms due to climate change amounts to US$2.8 billion globally (approximately 38% of the total economic loss of storms at present) at the year 2100, whi

Ocean acidification (OA) is increasingly recognized as a major global problem. Despite the scientific evidence, economic assessments of its effects are few. This analysis is an attempt to perform a national and sub-national assessment of the economic impact of OA on mollusc production in Europe. We focus on mollusc production because the scientific evidence on the biological impact on calcifying organisms is ample relative to other types of marine organisms. In addition, Europe and its regions a

Carbon dioxide capture and storage (CCS) is a technology that receives growing recognition because of its extremely great in mitigating climate change. However, uncertainties concerning the viability of this approach exist. With this background, the Intergovernmental Panel on Climate Change (IPCC) published a report in 2005 assessing of CCS. This article discusses the compilation process of the report, based on information collected through interviews with key participants and document research,

As climate change adaptation is becoming a recognized policy issue, the need is growing for quantitative economic evaluation of adaptation-related public investment, particularly in the context of climate finance. Funds are meant to be allocated not to any types of beneficial investments with or without climate change but to projects regarded as effective for climate change adaptation based on some metrics. But attempts at such project-specific evaluation of adaptation effects are few, in part b

As growing attention is paid to climate change adaptation as an actual policy issue, the significant meaning of climate variability in adaptation decisions is beginning to be recognized. By using a real option framework for adaptation in agricultural production, we shed light on how climate change and climate variability affect individuals' (farmers') investment decisions with regard to adaptation (switching from rainfed to irrigated farming). The option value delays adaptation easily for severa

Infrastructure projects in developing countries can have conventional development objectives such as economic growth or those of climate change adaptation. While some projects can serve both types of purposes, the conventional benefits are often more clearly appreciated than the latter. But a clear identification of the climate change implications of a project is also important. Such distinction would help associate climate finance with climate benefits directly. However, at present, no establis
