BIOGRAPHY OF DR. KENNY BROAD

Broad's long history of diving and documentary film expeditions includes the exploration of one of the world's deepest caves in the Huautla Plateau in Mexico. "You can't send a remotely operated vehicle in to explore caves because the technology simply doesn't exist," he says. "It's one of the few environments left on the planet where you must physically go to learn about it."

Underwater and aboveground, Broad is committed to an interdisciplinary approach—developing teams that bring together hydrologists, biologists, oceanographers, climatologists, psychologists, and anthropologists to see the big picture. "Traditionally, environmental and social problems have been looked at in isolation by different disciplines," he observes. "But until the sciences engage with people who actually experience problems and the policymakers who deal with those issues, we'll never find the best solutions."

Broad's interdisciplinary training includes an M.A. in marine affairs from the University of Miami, and a Ph.D. in anthropology from Columbia University. He is currently an assistant professor in the Division of Marine Affairs and Policy at the University of Miami and the Centre for Ecosystem Science and Policy and holds a joint appointment at Columbia University Lamont-Doherty Earth Observatory.

He also stresses the importance of recognizing and communicating the level of uncertainty inherent in any scientific information. Broad cites an example of this from his research to illustrate his point: "A climate forecast that's right eight out of ten years may be considered very successful in the science community. For a big farm, sustaining a loss two out of ten years for those 'missed' forecasts may be possible—even if it occurs two years in a row. But this may not be the case for a more vulnerable small farming household in northeast Brazil. Let's say that farmer changes his/her strategy to monocropping based on the forecast versus planting multiple crops to hedge against too much or too little rain. If the forecast is wrong the first two out of ten years, they'll have no seed for the next year's crop, and may in fact face a critical food shortage. So while being right 80 percent of the time is impressive from a scientific standpoint, how the probability plays out may be devastating for some farmers."

Despite such disparities, Broad believes that scientific fact can have great practical utility if all aspects of a problem are studied within context, uncertainties are openly communicated, unintended consequences are anticipated, and issues of equity in distribution of benefits are considered from the start.

"I don't believe in setting boundaries or firm expectations—those are just limitations. That's why I find both underwater cave exploration and interdisciplinary research so engaging. You never know what you're going to discover until you get there. You never know what the answer—if there is one—may turn out to be."
