From Adaptation to Tohoku Reconstruction, Japan
(JICA project in Bangladesh)
The adaptation measure for reducing climate change-induced disaster in Bangladesh can be adopted for recovery of disasters induced by the great Japan earthquake.

Summary
• From among many options for protecting coasts and river against erosion and other climate change-induced events, the importance of multiple-safe guard system is emphasized.
• The necessity of flexible structures from rigid ones is also emphasized for adaptation along the sea and river coasts including the levee.
• Utilization of locally available materials is recommended for soft structures.
Thank you for kind attention!
