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...

　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...

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...

Over the years, climate change adaptation has evolved to cover a range of issues providing long-term solutions to even the chronic developmental issues that couldn't be addressed with traditional solutions. The discourse on climate change adaptation has broadened the understanding of risk and risk management among stakeholders that contributed to...

Microplastics (MPs) and plastic-related chemical pollution are widely discussed in the literature. The presence of MPs in environmental compartments create adverse impacts on ecological systems and potential exposure of human through several pathways. Hence monitoring plays an important role in upstream and downstream mitigatory measures. The...
