Global climate change has resulted in a series of chain reactions in the ecohydrological processes. Growing concerns over watershed degradation, water scarcity, and ecosystem sustainability due to climate change require new approaches to managing forest water resources. Although little science-based guidance for forest managers and policy makers to adapt to the changing environment is available and many questions remain unanswered, we have accumulated information about the interactions between forests and water to make informed decisions.

Ecohydrologic science is tremendously valuable for maintaining, restoring, and enhancing water quality and supply. In order to provide a forum for experts from around the world on ecohydrology, restoration ecology, forest ecology, watershed management and global change sciences to share knowledge and research experiences, and develop long-term international collaborations on watershed research, The International Conference on Forest and Water in a Changing Environment has been held every three years since 2006. The first conference was held in Beijing, China. Over 90 scientists from 25 countries attended this conference and some papers were published in Journal of the American Water Resources Association. The second conference was held in Raleigh, North Carolina, USA. Over 140 scientists from eight countries attended the conference and some papers were published in Ecohydrology.

At this 3rd conference, we will continue to discuss forest and water relations in a changing environmental in Fukuoka, the gateway city linking Japan to the rest of Asia.
