Rapid disaster responses are essential for conserving the benefits that healthy reefs provide, however they are rarely included in post-disaster management plans and budgets. Instead, reef response is often dependent on reactive, time-consuming, and often unreliable fundraising, which disincentivises future investment. The Mesoamerican Reef (MAR) Fund, supported by WTW developed a uniquely designed parametric insurance product to provide cost-effective coverage to priority sites along the Mesoamerican Reef. This first insurance policy was purchased by the MAR Fund with financial support from the InsuResilience Solutions Fund. This is a use of parametric insurance, which is a type of insurance that pays the policyholder a set amount following an event rather than an amount based on calculated losses. This enables rapid, post-storm payouts. Storm wind intensity triggers immediate, post-storm payouts at specific levels to cover the costs of reef recovery response.
