This report builds on a vulnerability and adaptation assessment, which provided information on key threats to natural resources and the socio-political context of Lami Town, Fiji, and identified potential adaptation options to climate change. To further analyse these adaptation options, this synthesis report presents a cost-benefit assessment of four adaptation scenarios. These scenarios represent the spectrum of ecosystem-based and engineering adaptation options to reduce vulnerability to storms, which was identified by the Lami Town Council as the principal vulnerability concern. Examples of ecosystem-based options include replanting mangroves, reducing upland logging and reducing coral extraction; examples of policy and social options include regulating land tenure (informal settlements), relocating highly vulnerable households and flood warning systems and mapping. This report is intended to be used as the basis for development of a full adaptation plan for Lami Town.
