Land that was once used to grow food is increasingly being turned over to biofuels. This may help us to fight global warming - but it is driving up food prices throughout the world and making life increasingly hard in developing countries. Add in water shortages, natural disasters and an ever-rising population, and what you have is a recipe for disaster. . .
The era of "agrofuels" has arrived, and the scale of the changes it is already forcing on farming and markets around the world is immense. In Nebraska alone, an extra million acres of maize have been planted this year, and the state boasts it will produce 1bn gallons of ethanol. Across the US, 20% of the whole maize crop went to ethanol last year. How much is that? Just 2% of US automobile use. . .
The Indian government says it wants to plant 35m acres (140,000 sq km) of biofuel crops, Brazil as much as 300m acres (1.2m sq km). Southern Africa is being touted as the future Middle East of biofuels, with as much as 1bn acres (4m sq km) of land ready to be converted to crops such as Jatropha curcas (physic nut), a tough shrub that can be grown on poor land. Indonesia has said it intends to overtake Malaysia and increase its palm oil production from 16m acres (64,000 sq km) now to 65m acres (260,000 sq km) in 2025. . . JOHN VIDAL, GUARDIAN
