The former UN Special Rapporteur on the Right to Food, Jean Ziegler, has recently released a book entitled "We Let Them Starve: The Mass Destruction in The Third World". Unsurprisingly this has kicked up a real storm. From an interview with newsnet (the online presence of Swiss newspapers Basler Zeitung), although the tendency for collective accusation is worrisome, he brings up some of the complex issues (apart from global food production) that are at the heart of global starvation and chronic undernutrition - food speculation, national dept repayments and consumer behavior.

I haven't read the book yet, but its sailed right up on my must-read list.
