Here is a very encouraging story from Newsweek about social entrepreneurship and the kind of change that is possible when thinking outside of the box. The story highlights the innovative work of José Roberto Fonseca that is revitalizing the agricultural sector in one of the poorest districts in Brazil. Using a combination of solar energy and a process known as hydroponics, José has been able to create sustainable solutions for agricultural problems that inundate this arid region of Brazil.

But where others saw privation, Fonseca saw opportunity. "Poor people in the sertão have been farming beans, manioc and corn the same way they have since Brazil was discovered, and poverty is as bad as ever," he says, waving at the monotonous expanse of balding scrub and cactus. "It's time they tried something different."

Rapidly rising prices for palm oil and other kinds of vegetable oils are having a huge impact in the developing world, where many families grow their own food but must purchase oil in which to cook it. As the International Herald Tribune reports, this increase in the cost of edible oils is only the most recent development in the emerging global problem of rising food prices.
