Estimating the potential environmental risks of worldwide coastal recreational navigation on water quality is an important step towards designing a sustainable global market. This study proposes the creation of a global atlas of the environmental risk of marinas on water quality by applying the Marina Environmental Risk Assessment (MERA) procedure. Calculations integrate three main risk factors: Pressure, State and Response. Applying the MERA approach to 105 globally distributed marinas has confirmed the utility, versatility and adaptability of this procedure as a novel tool to compare the environmental risks within and among regions (i.e. for area-based management), to identify the world's best practices (i.e. to optimize existing management) and to understand and adjust global risks in future development (i.e. improved planning).
