March 2014Global Benefits of Marine Protected Areas
with Geoffrey Heal: w19982
Case studies suggest that Marine Protected Areas (MPAs) can be effective tools for fishery management. This study uses global datasets of MPAs and stock assessments to estimate the strength and robustness of their benefits. We apply multiple models, including a treatment-control pairing, a logistic model estimated with fixed-effects, and a regression tree to identify key characteristics. We find that regions with significant MPA designations increased their yearly yield by 17e3 MT/yr while those without experienced a loss of 20e3 MT/yr. On average, a 1% increase in protected area results in an increase in the growth rate of fish populations by about 1%. Considering only IUCN classified protected areas, and only marine portions of MPAs, growth rates increase 2% per percent area protected. M...
