MPAs and Aspatial Policies in Artesanal Fisheries

Peer Reviewed

Using a spatially explicit framework with low/middle-income country coastal characteristics, we explore whether spatial policies augment the impact of marine protected areas (MPAs) and identify when MPAs create income burdens on communities.

When SPAs are small and budget-constrained, they cannot resolve all of the marines cape's open-access issues, but they can create win-win opportunities for ecological and economic goals at lower levels of enforcement. Spatial policies -taxes, gear restrictions, license restrictions, and livelihood programs- improve the MPA's ability to generate ecological gains, and licenses and livelihood policies can mitigate MPA-induced income burdens. Managers can use MPA location and enforcement level, in conjunction with the MPA's impact on fish dispersal, to induce exit from fishing and to direct the spatial leakage of effort. Our framework provides further insights for conservation-development policy in coastal settings, and we explore stylized examples in Costa Rica and Tanzania.
