Ocean Overhaul

Marine zoning is a bold remedy for sick seas

These days not even many politicians deny that the oceans are ill. Protecting the health of coastal waters is now a matter of national policy in dozens of countries, including the U.S., and world leaders are beginning to prescribe a revolutionary remedy that conservationists have been promoting for years: marine planning and zoning.

The idea is a natural extension of management policies that have guided the development of cities and landscapes for nearly a century. Porn shops aren’t next to preschools, after all, and drilling rigs aren’t the centerpieces of national parks. Similarly, zoning advocates envision a mosaic of regional maps in which every watery space on the planet is designated for a particular purpose. Drilling and mining would be allowed only in certain parts of the ocean; fishing in others. The most critically threatened areas would be virtually off-limits.

Whereas people can easily find maps telling them what they can do where on land, the marine realm is a hodgepodge of rules emanating from an army of agencies, each one managing a single use or symptom. In the U.S., for example, one body regulates commercial fishing, usually a single species at a time. Another group manages toxic substances, still another seabed mining, and so on—some 20 federal agencies in all. They tend to make decisions without regard to what the others are doing, explains Duke University marine ecologist Larry B. Crowder. “Imagine all of the medical specialists visiting a patient in intensive care one at a time and never talking to one another,” he says. “It’s a wonder that the oceans aren’t in worse shape than they are now.”

Ocean advocates such as Crowder eagerly await the final recommendations of a special task force President Barack Obama charged with presenting a plan for overhauling management of U.S. waters, which extend 200 nautical miles offshore. The scope of such an undertaking is huge: the U.S. controls 4.4 million square miles of seascape, making the country’s underwater real estate 25 percent larger than its landmass. The committee’s preliminary report, released in September, suggests that the best way to minimize harmful human impacts on the oceans is to manage regions rather than symptoms.

Many environmentalists are hopeful that such plans will be implemented through the marine equivalent of municipal zoning, which would give them some influence in areas where they now have none. In zones where conservation is designated as the dominant activity, fishing and industrial activities such as mining would no longer have free rein. Under current rules, about the only way a conservation group can block a project it deems harmful—say, a new site for offshore drilling—is through expensive litigation.

So far, though, the president’s task force has been careful not to suggest that ocean zoning will be the only treatment plan, in great part because any effort to restrict commercial interests is bound to meet stiff opposition. “Zoning isn’t anybody’s favorite exercise,” notes John C. Ogden, director of the Florida Institute of Oceanography at the University of South Florida at Tampa. “Someone’s ox is always getting gored.” Most resistant to such change will most likely be the traditional users of the open ocean—namely, commercial fisheries and the petroleum industry. “They’ve had the place to themselves for a long time,” Ogden says.

Ogden and others are quick to point out, however, that zoning practices can benefit commerce as much as conservation. By giving up access to certain areas, industries gain the security of knowing their activities would be licensed in a more predictable and less costly manner than they are today, explains Josh Eagle, associate professor at the University of South Carolina School of Law. Now an oil company can apply for permits to drill virtually anywhere, but it takes on a significant financial risk each time. The business may dump millions of dollars into researching a new facility only to have a lawsuit derail it at the last moment. When opposing parties have more or less equal voices early in the planning process, Eagle says, they are less inclined to block one another’s activities once zones are drawn on a map.

Whether the final report of the president’s task force will promote ocean zoning explicitly is uncertain. But the group has already promised to overhaul the structure of ocean governance by proposing the creation of a National Ocean Council, whose job it will be to coordinate efforts of the myriad federal agencies now in charge.

The move comes just in time. Just as society is beginning to appreciate the enormous efforts it will take to preserve the health of the oceans, it must ask more of them—more energy, more food, and better resilience to coastal development and climate change. The reason the oceans are in trouble is not what people put in and take out. It is a failure of governments to manage these activities properly. Says Crowder: “We have to treat the oceans holistically, not one symptom at a time.”
