Consequently, building resilient infrastructure capable of withstanding such events is paramount, particularly for the most vulnerable emerging and developing countries. However, the increasing vulnerability to natural disasters exacerbates the challenges policymakers face in funding investments in much-needed climate-resilient infrastructure while keeping debt at sustainable levels.

One of the requirements for the successful deployment of RST funds is the assessment of funding needs to deal with such long-term challenges, including investments in resilience to natural disasters.
