As Hydrology Engaging Local People IN one Global world (HELPING) - the new decadal initiative by IAHS - emphasizes, incorporating local perspectives into research frameworks is becoming increasingly important. In this symposium, we present a conceptual framework for understanding human-water interactions, centered on four interrelated elements: value systems, governance, culture, and history. Developed by a group of scholars engaged in advancing sociohydrology in Japan, this framework may reflect cultural and historical contexts specific to the country, offering both globally shared insights and regionally grounded perspectives.
We hope this symposium contributes meaningfully to the promotion and integration of diverse regional perspectives in sociohydrology.

Local organizing event: Advances in Sociohydrology and its Potential for Interdisciplinary Research in Japan

The Early Career Researchers’ (ECR) Program at ISHC 2025 recognizes the essential role that early career scholars play in advancing sociohydrology with fresh perspectives and bold ideas. This dedicated program provides a platform for students and young professionals to share their experiences, build interdisciplinary skills, and form meaningful connections across regions and disciplines.
The ECR session will create an open space to discuss challenges specific to interdisciplinary and transdisciplinary research careers—ranging from navigating methodological complexity to establishing long-term collaborations. Through interactive and informal dialogue, the session will strengthen the ECR community, foster global exchange, and ensure that early career voices actively contribute to shaping the future of sociohydrology.
As the field continues to grow and evolve, insights from this session will be synthesized to help guide the broader development of sociohydrology in the years ahead.
