There’s more on water and biofuels producion, strictly ethanol on watercrunch. It concentrates on the amount of water used to process the grain once it has grown, rather than on the amount of water needed to grow it in the first place but the numbers are worth looking at.
The threat to world water supplies posed by biofuels has come to the surface following a water conference in Copenhagen earlier this week. It is worth reading Adam Cox’s feature on Planet Ark for an interesting analysis of some of the issues raised. In addition to Prince Willem-Alexander’s comments, Cox says This can mean using […]
