How do global changes in climate, land use and development translate into water security challenges for particular places, and how can local research and responses, as well as stakeholders' perspectives, inform wider understanding and action? This session will explore connections among global, regional, and local perspectives on water availability, water quality, water-related hazards, equitable access, and ecosystem health.

We bring together hydrology, environmental science, engineering, ecology, geography and social science to examine water security across scales. We welcome conceptual, methodological and empirical contributions connecting large-scale assessments with catchment-, urban- and community-level research.

Topics of interest include:
- Interactions between global environmental change and local water security;
- Multi-scale observation, modelling and assessment;
- Connections between scientific evidence, community knowledge and water management;
- Adaptation and management across scales;
- Comparative studies and synthesis examining how water security challenges and responses differ across climatic, socioeconomic and institutional contexts, and what can be learned or transferred between them.

We encourage contributions from diverse settings worldwide, including Africa, Asia, South America and Europe, across urban, peri-urban and rural environments. Interdisciplinary and transdisciplinary studies as well as collaborations with practitioners and communities are particularly welcome. Single-location studies are also welcome where connections across scales or wider implications are made explicit. The aim is to advance dialogue between global and local research and identify opportunities for shared learning and more effective water management.
