The Skimmer on Marine Ecosystems and Management

Risk plays a role in any situation where decisions must be made based on uncertain information. In finance, for example, investors must often choose between putting their money in a bank account with a low but guaranteed interest rate, or in a stock that may yield high returns but also has a chance of losing all value. The amount of risk that the investors are willing to accept is called risk tolerance. Inversely, the amount of risk the investors are unwilling to accept is called risk aversion. Both considerations affect investors' decision-making.

In very general terms, the human mind has a logical side (the left half of the brain) and an emotional side (the right half). The activities of MPA planning and management tend to engage the logical side, involving the application of math and science and developing practical solutions to conservation challenges.

In an article in the June 2009 issue of PLoS ONE journal, researchers take a different look at the concept of planning marine reserves. They suggest that selecting the areas of the ocean that should remain fished may be a more efficient management policy than selecting the areas where fishing should be banned.

Dear MPA News:

There was much to like about the International Marine Conservation Congress [held this past May in Washington, D.C., U.S.] and much to learn from it. Conference attendees put an impressive amount of ecological knowledge on display. And the conference did not lack for compelling visions of what wise policies should look like.
