can anyone suggest me the best method for assessing coastal vulnerability to climate change? Is there any standard protocol to fix the vulnerability index?
To assess the impact of climate change on any sector (coastal, inland, water resources, etc..) you could use scenario based approach. Since future climates projected by climate models have large uncertainty as to how much the change would be for any region, an approach of varied temperature/rainfall/sea level change scenarios projected by climate models would shed some light on their impacts. Let us say, If you have a well calibrated/validated model that could simulate storm surge due to tropical cyclones or winter storms, you may impose in your model, the changes in intensity or frequency of these storms in a future warmer world to assess future storm surge hazard that may inundate more coastal areas. In this case you may use future tropical cyclone climates projected by high resolution AOGCMs.
I think Bottom Up approach is suitable for coastal communities. There is no fix protocol. You have to screen out the indicators for the different dimensions of the vulnerability. Some of my papers may be of some help, pl.
