As the number of designated sites grows, multi-internationally designated areas (MIDAs)—areas where two or more international designations overlap—are becoming increasingly common. While MIDAs bring enhanced visibility and opportunities, they also add complexity and present governance and management challenges. Differences in objectives, governance structures, zoning systems and reporting obligations across designations can create difficulties for site managers and national authorities.
