Establish a resilience model for coastal ecosystems affected by tsunamis - consideration of biodiversity for environmental conservation management in coastal areas

Research grant

Project Description

The purpose of this research is to accumulate basic data related to the dynamic state and recovery mechanism of coastal ecosystems using vegetation from the tsunami area as an indicator. By using Iwate Prefecture, which has a high coast resource value, as a model region we will create a coastal ecosystem resilience (recovery) model by integrating field data based on on-site monitoring and spatial analysis data from GIS. As a result, we are creating an ecosystem conservation map to be used as base data for future coastal zone environment conservation management (reconstruction plan).
