This research focuses on the urban expansion occurring in the Kamrup Metropolitan District—an area experiencing significant urbanization—with the aim of understanding its patterns and projecting future growth. The research covers the period from 2000 to 2022 and projects growth up to 2052, providing insights for sustainable urban planning. The...

Dynamic monitoring of reservoir water storage in arid areas is important for water resources assessment, hydroelectric power generation and agricultural irrigation. However, existing reservoir water calculation methods often rely on in-situ measurements, which limits their application in data scarce regionals and for regional scale analyses. Hence...

The Mekong Delta, South East Asia's ‘rice bowl’, sustains more than 18 million people through its agricultural output. This yield is secured by efficient water management systems but is susceptible to climatic changes. As Vietnam's policies aim to optimize the delta's semi-mountainous regions reliant on rain-fed agriculture, this study investigates...

This research investigates the potential of utilizing recycled concrete aggregate (RCA) and recycled sand (RS), derived from crushed concrete cubes, as sustainable alternatives in construction materials. The study comprehensively evaluates the properties of RCA and RS, focusing on workability, impact resistance, abrasion resistance, and compressive...

This paper conducts a comparative analysis of green industrial policy strategies recently advanced by the European Union (EU) and the United States (U.S.), and extends insights to the evolving policy landscape in Japan. Its analysis underscores how the European strategy is characterized by a systematic approach that balances emissions constraints...

地球規模で進む気候変動は、気象の激甚化、そして洪水や干ばつなどの自然災害を世界各地で引き起こし、新たな人道危機を生み出している。すでに社会基盤が脆弱化している紛争下の人々にとって、気候変動はリスクを増幅させる要因にもなっている。気候変動の負の影響が人類の発展や国際政治・経済の安定を阻むこの気候危機とも呼ばれる状況は、「気候安全保障」という視点から捉えることができる。人間の安全保障を掲げて開発援助に注力する日本にとって、気候危機下の人道支援の現状を分析・評価することは、今後の外交政策を展望する上で必須の課題だと言えるだろう。 気候安全保障は「日本国内に直接生じる安全保障リスク」と「日本国外で生じる安全保障リスクから波及して生じる日本の安全保障リスク」の２つに分類できる。本稿では...

The escalating impacts of climate change necessitate a focused analysis of flood vulnerability in ecologically fragile and densely inhabited mountain areas, particularly in the Himalayan region. This study concentrates on the Kullu Valley within the Beas Basin, Himachal Pradesh, India, a locale characterized by its intricate terrain and dynamic...

Forests play a vital role in maintaining ecological balance and provide numerous benefits. The monitoring and managing of large-scale forest plantations can be challenging and expensive. In recent years, advancements in remote sensing technologies, such as lightweight drones and object-oriented image analysis, have opened up new possibilities for...

Since the 1990s, the Philippines has established numerous protected areas aimed at preserving re-gions with distinct biological and ecological characteristics. However, transitioning towards a more comprehensive approach to managing these protected areas, one that effectively conserves biodiversity while also supporting the welfare of local...

This study employed an advanced geospatial methodology using the Google Earth Engine (GEE) platform to assess soil erosion in the Satluj Watershed thoroughly. To achieve this, the Revised Universal Soil Loss Equation (RUSLE) model was integrated into the study, which was revealed through several analytical tiers, each with a unique function. The...
