What is TDA?

1) Inter-disciplinary(Civil engineering, Architect, Environment, Urban Planning, Social economics, and so on)- Complexed issues (disaster resilience, climate change, urban development,etc).
→ “Holistic approach” by various knowledge across discipline is required.

2) Stakeholder coordination / participation(National government - local government - private sectors - NGO - community - local residents)- Only science is not enough, implementation is important to reduce disaster risk.
→ Stakeholder coordination is essential on the implementation.

3) Scientific knowledge based decision-making- Scientific knowledge is fundamental to make correct decision among stakeholders.
- Knowledge sharing and risk communication is also very important topic.

Objective of ACECC TC21
Promote the transdisciplinary approach (TDA) for cientificnowledge-based
ecision-making (SKD) for building
societal resilience to disasters- Case studies of TDA practices in various countries- Comparative analyses and describe factors andpositive effects of TDA- Publication and dissemination5
