Mountain Hazards and Sustainable Watershed Management: A Synthesis of Research Published in Journal of Mountain Science

Mountain watersheds, critical for water provisioning, biodiversity, and livelihoods, are increasingly vulnerable to a spectrum of natural hazards, including landslides, debris flows, glacial lake outburst floods (GLOFs), and extreme hydrological events. These hazards, often intensified by climate change and anthropogenic pressures, pose significant threats to ecosystem integrity, infrastructure, and human security downstream. Sustainable watershed management (SWM) emerges as a vital framework to mitigate these risks while preserving ecological functions and supporting socio-economic resilience. This study presents a comprehensive synthesis of research published over the past decade in the Journal of Mountain Science (JMS), a leading platform dedicated to mountain research.

Through a systematic review and thematic analysis of pertinent literature from JMS, we identify key research trends, knowledge clusters, and evolving paradigms at the intersection of mountain hazards and SWM. Our synthesis reveals three dominant thematic strands: (1) advanced methodologies for hazard monitoring, modeling, and risk assessment using remote sensing, numerical simulation, and community-based approaches; (2) analysis of hydro-geomorphic processes and their sensitivities to climatic and land-use changes; and (3) evaluation of integrated management strategies, such as ecosystem-based disaster risk reduction (Eco-DRR), green infrastructure, and adaptive governance models.

The analysis underscores a shift from purely technical hazard control towards more holistic, socio-ecological systems approaches. Key insights highlight the necessity of coupling engineering solutions with the restoration and conservation of watershed ecosystems to enhance natural buffering capacity. Furthermore, the synthesis identifies critical research gaps, including the need for long-term interdisciplinary studies, improved transboundary governance mechanisms, and strategies that explicitly link upstream hazard mitigation with downstream water security and equitable benefit-sharing.

This synthesis consolidates foundational knowledge from JMS, offering a consolidated reference for scientists, policymakers, and practitioners. It concludes that the sustainable future of mountain regions hinges on integrative science and policies that concurrently address hazard reduction, watershed protection, and sustainable development goals.
