Marine Protected Area Totally Explained

Everything about Marine Protected Area totally explained

Marine Protected Area (MPA) is often used as an umbrella term covering a wide range of marine areas with some level of restriction to protect living, non-living, cultural, and/or historic resources. A commonly used definition is the one developed by the World Conservation Union. It defines Marine Protected Area as
Because the term "MPA" has been used widely around the globe, its meaning in any one country or region may be quite different than the one above. There are many related terms such as SPA (Specially Protected Area), MR (Marine Reserve), MP (Marine Park), NTZ (No Take Zone), or ASC (Area of Special Conservation) which have specific types of restrictions associated with them, as defined by the laws of the state. One example of the many names used for ocean protected areas can be found by looking at the National MPA Inventory for the United States. (External Link

) In the international arena there has been a similar plethora of concepts: Particularly Sensitive Sea Areas, Special Areas, etc.
Some see the purpose of MPAs as fully closed areas where no human activities should be allowed, while others see MPAs as keenly managed areas designed to enhance use and productivity of an area. The permissions given within an MPA often depends on the objectives (see Types of MPAs) of its establishment.

Types of MPAs

MPAs can be established for a multitude of reasons: to protect a certain species, to benefit fisheries management, or to protect full ecosystems, rare habitat, or nursing grounds for fish. MPAs are also established to protect historical sites as shipwrecks and important cultural sites such as aboriginal fishing grounds. MPAs can be very large (Great Barrier Reef) or very small (Area Marina Protetta Capo Rizzuto).
Typical restrictions in MPAs include ones on fisheries, oil and gas mining and access for tourism. Other restrictions may include the use of ultrasonic devices like sonar (which confuse the guidance system of cetaceans), development and construction and the like. Still others, such as New Zealand's marine reserves, are 'no take' areas, where all forms of exploitation are prohibited. Even navigation is at times regulated, sometimes so strictly to ban it all together, either as a preventive measure or to avoid direct disturbance to certain species. The degree to which environmental regulations can be enforced against foreign ships varies according to whether MPAs are located territorial waters, exclusive economic zone, high seas). The law of the sea regulates these limits.
For this reason, most MPAs have been located are in the territorial waters of coastal States, where enforcement of their regulations can be properly ensured. However, MPAs can also be established in a state's exclusive economic zone and even international waters. For example, Italy, France and Monaco, in 1999 jointly established a cetacean sanctuary in the Ligurian Sea named the Pelagos Sanctuary for Mediterranean Marine Mammals. This sanctuary includes both national and high seas waters.

Concerns

Quite often protection of these areas have shown an increase in the numbers and diversity of marine life and improvement of the overall health of the system. With that said, MPAs often create an ecological success, but can in certain cases also have a negative impact on the local communities. Some of these impacts include interpersonal conflicts, lack of enforcement (if an MPA can't be adequately marked on maps or by buoys, trespassing can occur), and the loss of fishing as an economic or food resource for the community. Proponents argue however that MPAs help increase fish stocks in the surrounding area so helping the local communities (External Link

). Indeed research by Callum Roberts found that adjacent fisheries increased from between 46 to 90% within 5 years. Roberts said describing his findings: "Despite some nervousness from fishermen about the establishment of marine reserves, our research shows that fisheries actually benefit from reserves within a very short space of time," (External Link

Sites

MPAs can be found all around the world. Some well known ones with articles available include:

The Great Barrier Reef in Queensland, Australia
