The proposed Special Issue, "Advancing Hydro-Environmental Science: Impacts, Adaptation, and Mitigation Strategies," focuses on emerging challenges and innovative solutions in the field of hydro-environmental science. With increasing global environmental pressures such as climate change, resource scarcity, pollution, and geo-hazards, there is a critical need for interdisciplinary research that bridges gaps between water, land, and atmospheric systems. This Special Issue invites original research articles, reviews, and case studies that address cutting-edge technologies, adaptive measures, and policy frameworks for improving environmental sustainability and resilience. By exploring themes such as air-water-biota-rock interfaces, pollution mitigation, natural resource management, and environmental risk analysis, this issue aims to provide actionable insights and foster collaboration among researchers, practitioners, and policymakers.
