Planting an Alternative to Petroleum

jatropha.jpgThe Sunday New York Times spotlighted a growing source for making biofuel, a plant called jatropha that the NYT reports “is being hailed by scientists and policy makers as a potentially ideal source of biofuel, a plant that can grow in marginal soil or beside food crops, that does not require a lot of fertilizer and yields many times as much biofuel per acre planted as corn and many other potential biofuels.”

Poor farmers living on a wide band of land on both sides of the equator are planting it on millions of acres, hoping to turn their rockiest, most unproductive fields into a biofuel boom. They are spurred on by big oil companies like BP and the British biofuel giant D1 Oils, which are investing millions of dollars in jatropha cultivation.

Countries like India, China, the Philippines and Malaysia are starting huge plantations, betting that jatropha will help them to become more energy independent and even export biofuel. It is too soon to say whether jatropha will be viable as a commercial biofuel, scientists say, and farmers in India are already expressing frustration that after being encouraged to plant huge swaths of the bush they have found no buyers for the seeds.

But here in Mali, one of the poorest nations on earth, a number of small-scale projects aimed at solving local problems — the lack of electricity and rural poverty — are blossoming across the country to use the existing supply of jatropha to fuel specially modified generators in villages far off the electrical grid. “We are focused on solving our own energy problems and reducing poverty,” said Aboubacar Samaké, director of a government project aimed at promoting renewable energy. “If it helps the world, that is good, too.”

Well, yeah. Meanwhile, Uncle Sam is pouring billions into subsidizing the American corn ethanol industry, which appears from here to be a costly mistake.

Jatropha’s proponents say it avoids the major pitfalls of other biofuels, which pose significant environmental and social risks. Places that struggle to feed their populations, like Mali and the rest of the arid Sahel region, can scarcely afford to give up cultivable land for growing biofuel crops. Other potential biofuels, like palm oil, have encountered resistance by environmentalists because plantations have encroached on rain forests and other natural habitats.

But jatropha can grow on virtually barren land with relatively little rainfall, so it can be planted in places where food does not grow well. It can also be planted beside other crops farmers grow here, like millet, peanuts and beans, without substantially reducing the yield of the fields; it may even help improve output of food crops by, among other things, preventing erosion and keeping animals out.

Other biofuels like ethanol from corn and sugar cane require large amounts of water and fertilizer, and factory farming in some cases consumes substantial amounts of petroleum, making the environmental benefits limited, critics say. But jatropha requires no pesticides, Mr. Samaké said, little water other than rain and no fertilizer beyond the nutrient-rich seed cake left after oil is pressed from its nuts.

A new fuel source that lowers dependence on petroleum, can help third-world farmers make a better living, and is better for the environment than making ethanol out of corn. Sounds like a win-win-win.  (Jatropha plantation photo from Tree Oils India Ltd.)
