This technical report presents a tool designed to help understand the consequences of climate change on the coastal zone systems of the Asia Pacific regions, and examine long-term adaptation and mitigation strategies.

The tool comprises three components: a model of hydrological and biogeochemical processes, an impact assessment tool and a multi-criteria decision-making tool. It focuses on flooding, nutrients, salinity and sedimentation in the coastal areas of Australia, Bangladesh, Japan, Sri Lanka, Thailand and Vietnam.

The report presents the methodology used to develop the tool, results of case studies conducted using the tool, and key findings. It highlights that different countries prioritise flooding issues and adaptation measures differently. The case studies are ongoing, and are due to be expanded to other parts of Asia Pacific and to include other issues such as groundwater.
