For the Jatropha seed yield three scenarios are considered: scenario 1 (worst case scenario i.e. lowest seed yield reported in literature), scenario 2 (base case scenario i.e. current assumption in study), and scenario 3 (best case scenario i.e. best seed yield reported in literature). For worst case scenario seed yield is taken to be 450 kg/ha , for base case seed yield is 2363 kg/ha, and for the best-case scenario seed yield is taken to be 5.9 ton/ha . In case of scenario 1 even at low seed yield Jatropha would reduce GWP impact considerably (~27.62%), however environmental impacts will increase significantly in other impact categories. Environmental impacts are increased because with decrease in seed yield more land and plants will be required for production of same amount of biodiesel. In case of scenario 3 (best case scenario), high seed yield of 5900 kg/ha would lead to significant reduction in global warming potential and eutrophication potential over base case scenario, however, acidification potential and human toxicity potential will reduce very less over base case scenario (Table ).
