5 Ways Marine Parks Benefit People

Every MPA is not created the same; some allow fishing and some do not, some are small and some are large, some are connected and some stand alone. When they are well planned and well executed, MPAs can help feed communities, protect jobs and boost biodiversity in the ocean. Here are the top five reasons why MPAs can be GREAT!

1. Spill Over Effects

The benefits of an MPA extend far beyond the boundaries of protection. When well planned, MPAs act as the home base for migratory species. These species use the protected area to reproduce, feed or congregate. But they do not stick around for long. This is called the “spill over effect” and it is hugely beneficial to local fishing communities. Even if fishing is restricted inside the MPA, just outside the border the fish are more numerous and far larger. For example, in Indonesia, community income increased 21 percent in 258 villages near a network of six protected areas.
