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.

To Feed the Future, Manage Seafood Smartly

By 2050, the world's population will have risen to 9 billion people. Consumption of fish as a percentage of protein in diets around the world is growing too, especially in the last five years as noted in a recent United Nations Report. Fish makes up over 16 percent of the world's animal protein food supply, and food fish supply, including aquaculture, has increased at an average annual rate of 3.2 percent, which means it’s growing at an even faster clip than the world's population. But the supply of wild-caught commercial fish species, such as tuna, is not infinite. Realistic, well-defined and long-term focused management strategies need to be in place now so that despite an unwavering growth in population and consumption, wild fish stocks can thrive well into the future.

Consumption of fish will continue to increase. In both the developing and developed world, more consumers want access to more fish. In less developed, food-deficit countries -- specifically coastal ones -- fish like tuna provide an affordable source of nutrient rich food.

Translating the language of fisheries economists for global ocean health

Economists speak a secret language. Markets, management, supply, costs, returns, rents – words I think I know, until I see them on a PowerPoint slide with a graph and an equation that starts with a sigma. Suddenly, it becomes clear these markets aren’t only the ones where I buy my peaches and rent is something more than a monthly check.

This past week I attended the bi-annual conference for the International Institute of Fisheries Economics and Trade. The hottest topics in fisheries economics were presented – the global state and outlook of aquaculture, capture fishery models, artisanal fishing, governance, rights based management, individual transferrable quotas, the impact of climate change, and dozens of others. Mostly comprising academics, the talks were technical, pithy, and representative of latest. An honest opportunity for discourse amongst equals to share and vet their work on ocean economies.

As a non-economist, I was in the minority here (though not a complete outsider – ecologists, trade experts, and fishermen were also in the mix). In spite of this lack of ‘expertise’ it is clear that the issue of ocean health is an economic one. We lose billions of dollars every year from mismanaging our fisheries and degrading ocean habitats. That money comes out of everyone’s our pockets. From small-scale fishers to large industry fleets to average consumers, we all pay the price. Economics can indeed play a large role in solving our ocean health problems, how challenging it is to get economists to agree on these solutions is another matter…
