Earlier this year, Time magazine ran a story on Florida entrepreneur Paul Dalton's new business growing jatropha trees, and the headline said, "The Next Big Biofuel?"
What made jatropha's biofuel seem promising, the story noted is that "unlike corn and other biofuel sources, the jatropha doesn't have to
compete with food crops for arable land. Even in the worst of soils, it
grows like weeds."
Well...not exactly, according to the latest issue of the Yale School of Forestry's newsletter "Yale Environment 360," which reports that Robert Bailis, an assistant professor at the Yale School of Forestry &
Environmental Studies, along with Yale Ph.D. candidate Jennifer Baka, recently
launched the first detailed “life cycle” environment assessment of jatropha as a
biofuel.
"Although their study is in its early stages, Bailis notes that it’s
already clear that, while jatropha can indeed grow on lands with minimal water
and poor nutrition, 'if you plant trees in a marginal area, and all they do is
just not die, it doesn’t mean you’re going to get a lot of oil from them,' " the story reports.
If you grow it in good farmland, though, it does just fine. But that's not good news. “If you grow it in better agricultural conditions, all the alarm bells go off as
you get into the same food-versus-fuel debate we’ve seen with [biofuel from]
corn," Bailis told the newsletter.
It's no idle concern, either. "According to the Indian
environmental group, Navdanya, government foresters have drained rice paddies in
order to plant jatropha in the poor and mostly tribal state of Chhattisgarh," the Yale newsletter reports. "As
early as mid-2007, protests broke out in the mostly desert state of Rajasthan
over a government scheme to reclassify village commons lands — widely used for
grazing livestock — as 'wastelands' targeted for biofuel production, primarily
jatropha."
Meanwhile, on the Philippine island of Mindanao, "protests erupted in late 2008, with indigenous leaders insisting that jatropha
plantations had begun to displace needed crops of rice, corn, bananas, and root
vegetables."
This all hits home for the Tampa Bay area, incidentally, because last year a Dallas company called GreenHunter Energy announced it would invest up to
$100-million in a biodiesel plant and terminal at Tampa's Port Sutton terminal to produce
50-million gallons a year from biofuel -- including from jatropha plantations in Central and South America.
