Earlier this century, jatropha was hailed as a "wonder" biofuel. An unassuming shrubby tree belonging to Central America, it was hugely promoted as a high-yielding, drought-tolerant biofuel feedstock that could grow on abject lands across Latin America, Africa and Asia.
A jatropha rush ensued, with more than 900,000 hectares (2.2 million acres) planted by 2008. But the bubble burst. Low yields resulted in plantation failures almost everywhere. The after-effects of the was tainted by accusations of land grabbing, mismanagement, and overblown carbon reduction claims.
Today, some researchers continue pursuing the evasive guarantee of high-yielding jatropha. A return, they state, is reliant on splitting the yield issue and addressing the harmful land-use concerns linked with its initial failure.
The sole remaining big jatropha plantation remains in Ghana. The plantation owner claims high-yield domesticated ranges have been attained and a brand-new boom is at hand. But even if this comeback fails, the world's experience of jatropha holds crucial lessons for any promising up-and-coming biofuel.
At the beginning of the 21st century, Jatropha curcas, a simple shrub-like tree belonging to Central America, was planted throughout the world. The rush to jatropha was driven by its pledge as a sustainable source of biofuel that could be grown on degraded, unfertile lands so as not to displace food crops. But inflated claims of high yields fell flat.

Now, after years of research study and development, the sole remaining big plantation concentrated on growing jatropha remains in Ghana. And Singapore-based jOil, which owns that plantation, claims the jatropha resurgence is on.

"All those companies that failed, adopted a plug-and-play design of searching for the wild varieties of jatropha. But to commercialize it, you require to domesticate it. This is a part of the procedure that was missed [during the boom]," jOil CEO Vasanth Subramanian told Mongabay in an interview.

Having discovered from the mistakes of jatropha's past failures, he states the oily plant could yet play an essential role as a liquid biofuel feedstock, decreasing transport carbon emissions at the global level. A new boom might bring fringe benefits, with jatropha also a possible source of fertilizers and even bioplastics.

But some scientists are hesitant, keeping in mind that jatropha has already gone through one hype-and-fizzle cycle. They warn that if the plant is to reach full potential, then it is vital to gain from past errors. During the very first boom, jatropha plantations were hindered not only by poor yields, however by land grabbing, deforestation, and social issues in nations where it was planted, including Ghana, where jOil runs.

Experts likewise suggest that jatropha's tale provides lessons for researchers and entrepreneurs exploring appealing brand-new sources for liquid biofuels - which exist aplenty.

Miracle shrub, significant bust

Jatropha's early 21st-century appeal originated from its guarantee as a "second-generation" biofuel, which are sourced from grasses, trees and other plants not derived from edible crops such as maize, soy or oil palm. Among its several purported virtues was an ability to flourish on degraded or "minimal" lands
