First is Depolarizing Food and Agriculture: An Economic Approach (Routledge/Earthscan, 2014), by Andrew Barkley and Paul W. Barkley. I offered a comment for the back cover:
When criticized on environmental or nutritional grounds, U.S. farm groups sometimes are tempted to adopt a thickly-armored defensive posture. In this daring book, respected agricultural economists Andrew Barkley and Paul Barkley offer a persuasive alternative. Echoing Schmpeter's vision of creative destruction (naturally), but also drawing on John Stuart Mill and Nelson Mandela (more surprisingly), the authors argue for an open and understanding approach to contemporary food and agriculture controversies, eventually offering hope -- as the title indicates -- for depolarizing food and agriculture.
Second is Agricultural & Food Controversies, part of the "What Everyone Needs to Know" series from Oxford University Press (2014), by F. Bailey Norwood, Pascal A. Oltenacu, Michelle S. Calvo-Lorenzo, and Sarah Lancaster. In a Huffington Post review, Jayson Lusk -- who was author of a more strident 2013 book called the Food Police -- notes the value of the new book's respectful discussion:
Rather than striking a defensive or muckraking tone, as so often is the case in this genre of writing, Norwood and colleagues embrace the controversies, interpreting them as a sign of a healthy democracy struggling to deal with pressing challenges. They reveal what the best science has to say on topics ranging from food pesticides and GMOs to the carbon footprint of beef production and the well-being of farm animals. They weigh in on synthetic fertilizers, local foods, and farm policy. Theirs is a respectful discussion of the positions taken up by different advocacy groups, but there is no hesitation in drawing conclusions where logic and science warrant.
