Brazil's ethanol revolution

"United Nations, June 2008 - The bio-fuel, ethanol, is generating a revolution in renewable energy that could help reduce the world's thirst for oil. In Brazil, the production of ethanol from sugarcane is booming, but what is not clear is the impact it is having on the industry's sugarcane cutters."  Transcript of video available here.

Blending gasoline with ethanol is the best way to increase octane.

S. AMERICA SCOOP:

The 'ethanol revolution' occurring in Brazil is a critical topic to examine in terms of global geography. With it's ethanol export rising 70% as of 2007-08, and with an abundance of sugarcane, Brazil is now beginning to offer an alternative to tradition fuels (especially for cars). Brazil is exporting a great deal of ethanol which is stimulating its economy, but there is a negative side to this energy boom. It's causing a great deal of unemployment in Brazil due to the mechanization of the process of sugarcane cultivation. The effects of a country or region's main commodity always goes under this mechanization process, it just depends on when the need for that commodity arises (this kind of relates to "Guns, Germs, and Steel" and the idea of determinism).

This sounds like something that people need to learn from, making fuel from sugar and alcohol. It is said that because of this Brazil is a world leader in in this sector. Doing so reduces emissions making a cleaner environment. This is future. .Doing things such as this and making machine mechanized cutters is good too, because now humans do not have to do it. When humans by hand get the sugar they have to burn plants, and burning plants pollutes the air because of the fire and the fire can cause severe destruction if it gets out of hand. With hand picking going out, it will be better overall. Delivering ethanol to the rest of the world is believed to lift the developing world out of poverty. .

Although ethanol is working well for Brazil, there is a growing literature supporting the idea that wide-scale ethanol production is not sustainable or environmentally beneficial.  This is a great example to demonstrate that economic and environmental policies are locally dependent on geographic factors and are not universally transferable.  Click here for a simple explanation of the differences in the economic and environmental differences in the production of sugar and corn-based ethanol.

Until now, there has been a lack of solid, comprehensive spatial data about African groundwater resources.  Researchers have now done so.  For a more academic article on the subject, here are their findings in Environmental Research Letters.
