Evolution of Water Governance for Climate Resilience: Lessons from Japan’s Experience

Water resources management needs to be strengthened to address increasing flood and drought risks exacerbated by climate change and socio-economic development. This requires effective water governance mechanisms that can reduce vulnerability in disasters while managing complex stakeholder relationships. This paper analyzes the evolution of water governance in Japan over more than half a century, examining how the country transformed from a centralized, top-down approach to a more collaborative model of water management. Through an analysis of three significant water infrastructure projects, this study identifies key drivers of governance change and evaluates the effectiveness of various stakeholder engagement mechanisms. The findings reveal how catalytic events prompted institutional innovations in addressing social impacts, environmental concerns, and climate resilience. Challenges remain in balancing diverse interests, managing implementation timeframes, and incorporating climate change uncertainties into decision-making processes. This paper offers important lessons for developing countries working to strengthen their water governance frameworks, particularly regarding stakeholder engagement, social impact mitigation, and the development of flexible institutional arrangements that can adapt to emerging climate risks. This research contributes to governance theory by demonstrating how institutional evolution occurs through the interaction of formal mechanisms and informal processes in response to changing social, environmental, and climatic conditions.
