Climate risks and adaptation in Asian coastal megacities: A synthesis

consider broad institutional issues, a more detailedcapacity analysis could provide a more nuancedunderstanding of policy and regulatory gaps, existingplanning and decision-making processes, coordinationbetween key municipal organizations, andentry points for strengthening state, private sectorand civil society relations with respect to addressingurban adaptation.Uncertainties, limitations, and interpretingthe findings of this studyAny study forecasting conditions four decadeshence will be faced with large uncertainties. Oneissue facing the analysis was what would be thepathway of GHG emissions. To address that issue,the city case studies examined both a high and alow GHG emissions scenario to bracket the likelyfuture conditions. In the climate change downscalingmethodologies, there are uncertainties inforecasting the increase in extreme and seasonalprecipitation under the different scenarios. Thetechniques applied in the statistical downscalingexamined the results from numerous AOGCMs.Robust relationships were identified for temperatureand precipitable water increases, where theinternal error was estimated at ~ 10 percent errorand ~ 10–20 percent error, respectively (Sugiyama2008). Hydrologic models can simulate flood eventswith relatively small errors (
