Abstract

Marine protected areas (MPAs) are increasingly being used globally to
conserve marine resources. However, whether many MPAs are being effectively
and equitably managed, and how MPA management influences substantive
outcomes remain unknown. We developed a global database of management and
fish population data (433 and 218 MPAs, respectively) to assess: MPA
management processes; the effects of MPAs on fish populations; and
relationships between management processes and ecological effects. Here we
report that many MPAs failed to meet thresholds for effective and equitable
management processes, with widespread shortfalls in staff and financial
resources. Although 71% of MPAs positively influenced fish populations,
these conservation impacts were highly variable. Staff and budget capacity
were the strongest predictors of conservation impact: MPAs with adequate
staff capacity had ecological effects 2.9 times greater than MPAs with
inadequate capacity. Thus, continued global expansion of MPAs without
adequate investment in human and financial capacity is likely to lead to
sub-optimal conservation outcomes.
