“…Costello & Polasky (2008) use interannual spatial models to identify years in which a reserve is optimal, based on ecosystem dynamics. Englander (2021) reveals the role of temporary closures to protect juvenile anchoveta in Peru in providing information to fishers that leads to increased total juvenile catch. Given the common use of temporary actions for fishery management, spatially dynamic MPAs could prove a useful and acceptable policy tool in addition to permanent, stationary MPAs.…”

Marine protected areas (MPAs) provide both conservation and economic benefits. Recent international conservation actors have called for a dramatic increase in the area of MPAs from almost 8% to 30% of marine area by 2030 in a policy called 30X30. Both the economics and conservation science literatures consider MPA decisions and MPA impact, although the economics literature focuses on fishery economic outcomes. This review uses an optimization framework for MPA decisions as a lens through which to evaluate the economics literature on MPAs in the context of the 30X30 expansion decisions. We argue for more economic analysis of MPA policy questions, including those around siting, design, restrictions, and management choices; impact evaluation; responses of people; low-income country settings and incomplete enforcement; spatial settings without metapopulations; and conservation rather than harvest objectives. Expected final online publication date for the Annual Review of Resource Economics, Volume 14 is October 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

“…They also often require detailed vessel-level data, which are rarely available globally even with modern satellite tracking. Causal inference methods have been effective in examining regional effects of individual marine protection policies ( 15 – 18 ), but these methods require an unaffected control group, which by definition does not exist for a policy that induces global effects. As a result, simulations of large-scale MPA expansions have relied on heuristic assumptions of fisher responses, such as assuming no change outside MPAs or a uniform reallocation of effort from within MPAs to areas outside ( 19 – 23 ).…”

Global expansion of marine protected areas and the redistribution of fishing effort

The expansion of marine protected areas (MPAs) is a core focus of global conservation efforts, with the “30x30” initiative to protect 30% of the ocean by 2030 serving as a prominent example of this trend. We consider a series of proposed MPA network expansions of various sizes, and we forecast the impact this increase in protection would have on global patterns of fishing effort. We do so by building a predictive machine learning model trained on a global dataset of satellite-based fishing vessel monitoring data, current MPA locations, and spatiotemporal environmental, geographic, political, and economic features. We then use this model to predict future fishing effort under various MPA expansion scenarios compared to a business-as-usual counterfactual scenario that includes no new MPAs. The difference between these scenarios represents the predicted change in fishing effort associated with MPA expansion. We find that regardless of the MPA network objectives or size, fishing effort would decrease inside the MPAs, though by much less than 100%. Moreover, we find that the reduction in fishing effort inside MPAs does not simply redistribute outside—rather, fishing effort outside MPAs would also decline. The overall magnitude of the predicted decrease in global fishing effort principally depends on where networks are placed in relation to existing fishing effort. MPA expansion will lead to a global redistribution of fishing effort that should be accounted for in network design, implementation, and impact evaluation.
