Abstract
Summarising CBD target 3 to “30 × 30” emphasizes area coverage, but conservation success depends on MPA quality. Many existing MPAs are under-protected, and rapidly designating new areas risks creating ‘paper parks’ without ecological or social benefits. Prioritizing strictly or fully managed MPAs, supported by a clear and shared definition, is essential to achieve meaningful biodiversity outcomes. Quality-focused strategies ensure that global targets benefit both nature and people, rather than merely meeting numerical goals.
