概要	<p> This study examines the economic and financial challenges of implementing climate change adaptation measures in these vulnerable countries. The costs and feasibility of various adaptation strategies, including coastal protection, land raising, and migration, were analyzed. Findings reveal that the financial requirements for effective adaptation far exceed the economic capacities of the RMI. The benefit-cost ratios of adaptation projects fall below 1 when evaluated solely on disaster risk reduction, highlighting the need for a paradigm shift in assessing adaptation investments in highly vulnerable nations. This study underscores the critical importance of international climate finance and support. The key challenges included debt sustainability concerns and traditional land tenure systems, ecological impacts, and the limitations of conventional cost-benefit analyses in the context of national survival. .</p>
