Two pieces providing much more substance than the now-normal superficial news story, on optimizing resources allocated to biofuels and food supply.
The first report urges governments to initiate an orderly, "innovation-enhancing" transition towards incentives targeted on multi-dimensional goals for biofuels development. These goals should include poverty alleviation, reducing net greenhouse gas emissions, increasing use of non-food feedstocks, attaining sustainable biofuel production targets and conserving biodiversity. http://www.greencarcongress.com/2008/07/researchers-sug.html Link at end of the page.
The second is an economic analysis arguing that biofuels are here to stay, even without government subsidy, if oil prices remain above $100 per barrel. The author provides a wide range of scenarios for policies and renewable fuels standards. Graphical presentation helps non-economists to visualize the possibilities.
