Floods have catastrophic effects worldwide, particularly in monsoonal Asia. This systematic review investigates the literature from the past two decades, focusing on the use of remote sensing (RS), Geographic Information Systems (GISs), and technologies for flood disaster management in South Asia, and addresses the urgent need for effective...

Urbanization is a major driver of land-use change, with significant implications for sustainable development in rapidly growing cities. In this study, we assess the spatiotemporal patterns of urban expansion in Lucknow, India, from 1991 to 2021, using geospatial techniques and Landsat satellite imagery. The key objective is to analyze urban growth...

Water cycle resilience represents a vital part of sustainable water resources management for a region with severe water vulnerability issues. However, despite their importance, a current lack of systematic monitoring mechanisms has contributed to an insufficient grasp of their distribution in relation to water resources management practices, as...

本研究は、地球規模で喫緊の課題となっている気候変動と生物多様性保全の観点から、カカオ生産における森林減少の実態と、持続可能な生産体制構築に向けた課題を明らかにすることを目的とした。特に、日本にとって最大のカカオ供給国であるガーナを対象に、カカオ生産と森林減少の関連性を分析するとともに、生産現場における課題を把握するため質問票調査を実施した。 分析の結果、近年の天然林の減少が森林保護区と国立公園に集中していることが示された。このことは、カカオ生産による森林減少のリスクを評価する上で、生態学的観点のみならず、生産国の土地利用政策を考慮した総合的な検討が不可欠であることを示唆している。また、質問票調査の結果から、認証を取得している農家であっても...

The scenario analysis has emerged as indispensable tool to envision the future conditions of biodiversity and ecosystem services (BES). The unprecedent urban expansion worldwide is expected to degrade the biodiversity and ecosystem services support local livelihoods, provide food, and enhance equity and human well-being. Therefore, it is crucial to...

This book examines urban water ecosystem management and restoration through selected case studies in Asia and Africa. Employing a socioecological approach, this volume presents insights on the interlinkages between water, humans, and environmental conservation in an urban context. Topics include human health risks, population displacement and...

Historically, urban areas were built with the presence of freshwater ecosystems. It is well recognized that freshwater is a significant factor in urban growth and development, which supports the reciprocity of urban growth and water environments since historical times. Yet, what is not often realized is that freshwater is a subset of complex socio...

The idea of integrated water resource management (IWRM) for comprehensive and sustainable management of river and lake basins has been present in academia and policy-making for over half a century. Despite its presence in academia and policy-making for some time, IWRM has seen some major bottlenecks, such as a lack of comprehensive and holistic...

Japan is considered a water-rich country. Yet, recent socioecological history suggests that the country has undergone some drastic changes in its water environment as an extended effect of its post-war industrialization and urbanization. On the other hand, Japan also houses ingenious and time-tested methods of water management in its traditional...

Coastal cities in Vietnam are increasingly impacted by rapid environmental changes and the growing frequency and magnitude of hydrometeorological hazards, such as extreme precipitation and droughts. One of the most significant challenges posed by climate change is the imbalance of water resources availability between the wet and dry seasons. Both...
