It is also important to note that our industry is not just looking at one source for biofuel supply - we are also investigating camelina, halophytes and of course algae as a source of sustainable biofuel. It is very unlikely that we will ever look to one source and therefore would not need to use 3.5 million sq kms of land to grow Jatropha. But it may form part of the mix. Interesting to note in comparison, enough oil can be extracted from around 35,000 sq kms of algae ponds to produce enough fuel for the aviation sector.

It would be really useful to be able to use this piece authoritatively. Jatropha does indeed seem to be a very partial solution, with potential to be a real problem. Many thanks Sarah Hi Chris

The waste area around these lakes could be a boon if used to grow bio-fuel. http://ecoworld.com/features/2003/08/12/seawater-farms/ Salicornia can be grown using saltwater in dessert sea coasts or maybe even inland in Australia if the saltwater lakes were filled or refilled using a seawater pipeline from the coasts to refill the saltwater lakes that are dry for now because of the draught.
