ABSTRACT
Conservation's capacity to deal with anthropogenic environmental threats within Marine Protected Areas (MPAs) varies enormously, especially in developing countries that are often immersed in weak enforcement, ineffective management and shortages of resources. A deeper understanding of the causes of these threats is fundamental for identifying effective management solutions. Here, we investigate the presumptive drivers of environmental threats across 40 Brazilian MPAs. We categorized and quantified environmental threats from two independent sources i) the results of systematic social surveys carried out as part of WWF's RAPPAM assessment, as primary data source, and; ii) data gathered from news media articles related to the MPAs (secondary data source). We identified 461 reports of threats that we classified into three general categories overexploitation, urbanization and land use threats. The presence of overexploitation threats was strongly associated with extreme poverty of local communities close to the MPAs. Threats also seem to be more frequent in category V MPAs, which in Brazil are Environmental Protection Areas (EPA), with multiple use objectives. Threats were concentrated on the North and Southeast coasts of Brazil. We found that data from news media can be used for qualitative assessment of threats, but has limited potential for quantification. Our findings highlight the need for policy makers and MPA managers to adopt a broader perspective that considers the role of social inequalities in promoting and exacerbating environmental threats. While recognizing that conservation has limited capacity to address the widespread social inequalities found in many tropical developing countries, if the socioeconomic context of local communities is significantly compromising conservation efforts it may be necessary to target and prioritize social interventions as a prerequisite for effective MPA management and governance.
