An integrated spatial planning model for climate change adaptation in coastal zones

Abstract

This research highlights the spatial planning approach for coastal sustainability and adaptation to climate change. The dilemma of spatial planning in a dynamic and complex coastal environment as well as the establishment of a coastal buffer zone as an adaptation measure for climate change are elaborated upon. In particular, this study outlines the limitations of two of the traditional approaches used for spatial planning (optimization and simulation) and the opportunities that present themselves when combining both models for coastal zone planning. As a result, this study has developed an integrated modeling framework called MOPSD (Multi-Objective Programming and System Dynamic) that can be used for spatial land use planning in coastal areas. The case study is Cijin Island, located next to the Kaohsiung harbor, Taiwan; this location demonstrates that the proposed MOPSD modeling approach generates superior results when compared to each of the two traditional methods. This is mainly attributed to the consideration of deterministic and dynamic characteristics when evaluating the climate change adaptation at risk of coastal erosion.
