"For the last 10 years, his plot in southern Ethiopia had kept his family of four alive by supplying enough food to eat and even surplus to sell, in a region often ravaged by drought and food shortages.
But since swapping from a subsistence to a biofuel crop several months ago, his once treasured source of income has dried up and, worse still, he and his family are now dependent on relief from aid agencies." (Thanks Marcy)
