Regional droughts are increasing in frequency and climate change projections indicate an exacerbation in the occurrence of regional droughts in the future. Droughts are complex hydrometeorological events, and the complexity of cause-and-effect relationships across administrative and political borders can make drought management a challenge. While...
Forest ecosystems play an indispensable role in addressing various pressing sustainability and social-ecological challenges such as climate change and biodiversity loss. However, global forest loss has been, and still is today, an important issue. Here, based on spatially explicit data, we show that over the past 60 years (1960–2019), the global...
Accurate urban morphology provided by Local Climate Zones (LCZ), a universal surface classification scheme, offers opportunities for studies of urban heat risk, urban ventilation, and transport planning. In recent years, researchers have attempted to generate LCZ maps worldwide with the World Urban Database and Access Portal Tools (WUDAPT). However...
Tracking decarbonization effects requires a model for the identification of spatial energy demands on city facilities. However, most developing countries lack detailed discrete time and device-specific energy demand data. In this study, we installed multiple energy demand monitoring systems that could observe electricity demands at the device level...
This policy brief aims to answer a critical question: how can policymakers, civil society, and researchers address air pollution, climate change, and socioeconomic equity with inclusive solutions? The brief argues that much of the answer will involve reframing how policymakers, civil society groups, and researchers perceive the interrelationship...
Forest ecosystems play an indispensable role in addressing various pressing sustainability and social-ecological challenges such as climate change, biodiversity loss, and ecosystem services deterioration, hence the monitoring of the world's forests is crucial. As part of the global forest assessment workflow, a forest is generally classified and...
River meandering and anabranching have become major problems in many large rivers that carry significant amounts of sediment worldwide. The morphodynamics of these rivers are complex due to the temporal variation of flows. However, the availability of remote sensing data and geographic information systems (GISs) provides the opportunity to analyze...
This paper examines the effects of financial incentives, particularly electricity prices, on residential solar photovoltaic system installations. We shed light on the importance of a factor that has been largely overlooked in the literature on the adoption behavior of low-carbon building technologies: the distinction between retrofit and new-build...
世界経済の成長センターとなってきた東アジアが様々なリスクにさらされています。緊張が高まる台湾海峡や朝鮮半島といった伝統的な安全保障リスクだけではありません。中国の台頭などによるパワーシフトと戦後の国際秩序の揺らぎが地政学的リスクを増大させ、「新冷戦」とも称される米中の大国間競争の影響が地域の経済や産業、科学技術、文化、教育など多方面に及び始めています。米ソの冷戦の最前線が欧州だったのに対し、「新冷戦」の最前線は東アジアだとの見方があります。
この地域の著しい技術革新や産業経済の発展自体も新たなリスクをもたらしています。人工知能（ＡＩ）などのデジタル技術の発展はさらなる経済成長のエンジンとなる一方、人々の想像を超えて、経済社会の在り方そのものを変える可能性があります...
This article quantifies the environmental, health, and economic co-benefits from the use of solar electricity and heat generation in the Ger area (a sub-district of traditional residences and private houses) in Ulaanbaatar (UB), Mongolia. The quantification of the featured co-benefits is based on calculating emissions reductions from the...
