Economic Feasibility and Sustainability of Jatropha as a Crop

Abstract

Jatropha curcas L. has the potential to be a suitable source of biofuel feedstock because of its favourable physical and chemical properties. All reports till date show that jatropha oil can reduce greenhouse gas emissions of up to 82% as opposed to fossil fuel indicating the ecological value of the jatropha system. Jatropha cropping has also been shown to be energy efficient, i.e. it results in production of more energy than it uses. Its cultivation has, however, not gained momentum in the last years due to plantation productivity concerns and the general lack of new investments in the biofuels sector. This chapter attempts to determine the intrinsic value of the various jatropha products relative to other comparable products now in the market. Based on this estimated intrinsic value of jatropha seeds, it could be deduced that a seed productivity of between 2000 and 4300 kg per ha per year from mature jatropha plantations would be required to reach crop profitability depending on framework conditions existing at the cultivation site. The main factors that influence the required range of yields for profitability are the selling price of oil at farm gate, the variety of jatropha (edible or toxic) cultivated and labour costs. Jatropha seeds improved by selection and breeding are required for reaching this range of seed productivity on the type of lands usually available for jatropha cultivation.
