Often, the use of biofuels has been associated with mitigating green house emissions. But in reality, the environmental cost of bioenergy crop cultivation and biofuel production reveals a different scenario. Palm, which was one of the front runners in biofuel feedstock during the past, became environmentally and politically radioactive because of the severe environmental cost associated with it. The emergence of second generation biofuels, especially Jatropha, Camelina etc were mainly on the basis of their ability to grow on marginal land and hence the low environmental impact due to mass cultivation. However, the equation has totally changed now. With increased commercial plantations of Jatropha and expanded acreages, the plant is in the path of becoming environmentally expensive.
Action Aid and Nature Kenya have recently criticised plans to clear thousands of hectares of Woodlands in Kenya to make way for plantations of jatropha, which can be used to make “green” fuels. In a scenario where the EU nations are passing Jatropha biofuels off as a green solution to climate change, the report from Nature Kenya has definitely come as a shock.
The report claims that like most other biofuels, Jatropha could actually end up increasing carbon emissions. The cost of destroying forests as part of expanding bioenergy plantation would far outweigh any savings made on carbon emissions. It was reported that greenhouse gas emissions because of the destroyed woodland would be up to six times higher than from petrol. The study took into account the emissions produced throughout the production and consumption process, and found that Jatropha would emit between 2.5 and 6 times more greenhouse gases.
Clearing of woodlands for Jatropha cultivation, is just one example of the disastrous but unseen impact of biofuels on the climate and environment could very well be possible.
Jatropha already being associated with socio economic problems, the new issue of environmental problem now reported could impede the near term success of Jatropha business.
