Marine Protected Areas : Are They Generally Effective

Whether coral reef marine protected areas actually protect at risk species is an important issue to consider . Knowing the answer could lead to a better ability to answer other questions about marine environments For example , a more defined correlation could be made between the increasing number of shark attacks in coastal areas and the overfishing of marine populations on which sharks subsist

The effectiveness [banner_entry_middle]

of marine protected areas (MPAs ) is of key importance in assessing whether certain efforts to protect at risk species actually work . Given that 70 of the planet is covered in ocean , species in terrestrial habitats are certainly affected by the biological status of marine environments . The growing degradation of biodiversity and biomass in earths ‘ marine ecosystem could be driving sharks to find more fulfilling meals in non-traditional feeding areas – coastal areas that humans use for recreation

The therefore deserves research because the very actions of terrestrial species , like humans , may generate harmful long-term effects . In essence , users of marine resources are demonstrably interested in the relative short-tem gains from marine ecosystems while ignoring long-term effects of over-usage . Yet , setting aside areas to protect after or from over-usage does not necessarily mean all marine species are protected . More important , the enforcement of marine protected areas (MPAs ) conflicts with socio-economic issues in communities that currently fish them or did so in the past

The mainstream article Marine-protected Areas : It Takes a Village Study Says ‘ looks at just how much society may assume about the extent of protection at risk species receive . When told an area is protected it is logically assumed that no fishing takes place in an MPA . To that end and by way of explanation , this article posits that the issue of protection actually depends on the consideration of at least three factors . The factors are as follows (1 ) how affective is the management of a MPA (2 ) whether management takes into account socio-economic effects on local communities and (3 ) whether the socio-economic effects will complicate enforcement of an MPA

In essence , the article attempts to tell the audience that MPAs are made more effective for the consideration given local socio-economic issues . The article implies that on average MPAs are not as effective as hoped and even hazards and explanation . For example , government controlled MPAs , invisible to a community propose two immediate dangers to the MPA by reason of invisibility . The community is both unaware of the benefits of avoiding overfishing and equally ignorant of methods of MPA enforcement

The article ultimately surmises that on a large scale , consideration being given to all marine protected areas , the most effective means of preserving species diversity , number and size would involve applying both the methods of traditionally managed systems (MPAs for small areas and permanent marine protected areas (usually large . In such a scenario permanent MPAs would benefit species with slow overfishing recovery… [banner_entry_footer]
