TED Talk Thursday – Greg Asner: Ecology from the air

According to TED.com: “What are our forests really made of? From the air, ecologist Greg Asner uses a spectrometer and high-powered lasers to map nature in meticulous kaleidoscopic 3D detail — what he calls “a very high-tech accounting system” of carbon. In this fascinating talk, Asner gives a clear message: To save our ecosystems, we need more data, gathered in new ways.”

“The remote sensing techniques developed by Greg Asner and his team are viewed as among the most advanced in the world for exploring Earth’s changing ecosystems in unprecedented detail and richness. Using airborne and satellite technologies such as laser scanning and hyperspectral imaging, combined with field work and computer modeling, Asner measures and qualifies humans’ impact on regions from the American Southwest to the Brazilian Amazon.”

“We’re able to see, if you will, the forest and the trees at the same time,” Asner says. “We’re able to now understand an image, map and measure huge expanses of the environment while maintaining the detail. Not just the spatial resolution, but the biological resolution—the actual organisms that live in these places.” For Asner, who is on the faculty at the Carnegie Institution and Stanford and leads the Carnegie Airborne Observatory project, this is science with a mission: to influence climate change treaties and save the forests he studies.”

Enjoy.

For those of you not familiar with TED Talks here is a brief summery from www.ted.com: “TED is a small nonprofit devoted to Ideas Worth Spreading. It started out (in 1984) as a conference bringing together people from three worlds: Technology, Entertainment, Design. Since then its scope has become ever broader. Along with two annual conferences — the TED Conference in Long Beach and Palm Springs each spring, and the TEDGlobal conference in Oxford UK each summer — TED includes the award-winning TEDTalks video site, the Open Translation Project and Open TV Project, the inspiring TED Fellows and TEDx programs, and the annual TED Prize”
