Jatropha as a feedstock is promising. Belize is in its infancy when it comes to Jatropha and Moaning is telling Fairy Tales to say that it is a sustainable feedstock at this time. This Govt of Belize Agriculture dept. link shows no stands of Jatropha trees in Belize at this time. http://www.agriculture.gov.bz/bfr/_mafc.htm
But you cannot compare a mature industry in India to an infant industry in Belize. What grows in India may not work in Belize and vice versa.
But "estimates of Jatropha seed yield vary widely, due to a lack of research data, the genetic diversity of the crop, the range of environments in which it is grown, and Jatropha's perennial life cycle. Seed yields under cultivation can range from 1,500 to 2,000 kilograms per hectare, corresponding to extractable oil yields of 540 to 680 liters per hectare."[6]
Approx. 1,000 gal/acre.
The issues remain. 1. Belize does not have a lot of land available for any feedstock that takes away from the food chain. Even intercropping can diminish food production.
2. There are no plantation of Jatropha or large Jatropha farms in Belize. It is growing wild and this is an inefficient and expensive collection method.
3, Jatropha yields in India can not be compared to Jatropha yields in Belize anymore than you can compare wheat yield in Iowa to wheat yield in Belize. We are attempting to compare apples and oranges.
