Food's Frontier: The Next Green Revolution

You have to approach with trepidation a book which has a cover blurb from the despicable, antihuman, scare monger Paul Ehrlich and which the author warns you was funded by a private organization (The McKnight Foundation) that funds the projects which he's going to be discussing. Right off the bat it just seems extraordinarily unlikely that you'll get a calm, balanced and non-dogmatic presentation of the issues. It's a pleasant surprise then that Richard Manning, despite a sleight over reliance on Ehrlichean "sky-is-falling" rhetoric, is able, at least to my non-expert eyes, to offer a full and fair look at some of the current debates surrounding the future of agriculture generally and, more specifically, the issues that arise out of the need to boost crop yields in developing countries to meet the rising food demands of their constantly increasing populations. Manning's basic premise is that the original Green Revolution--largely a product of improved fertilizers, pesticides, and breeding techniques--has hit a wall and is no longer providing the types of increases in production which have characterized the past thirty or forty years. Nor is there any readily apparent successor Revolution to step in and provide the necessary increases. He proposes that the answer to pending food supply problems then will not come from such a top down revolution but rather will have to rely on myriad local solutions : The Green Revolution at its most fundamental level treated all the world the same, but the lessons being learned in agriculture now are local. A practice, a variety, a people, and a crop endure in a place because selection has finely tuned them to survival. They have evolved along with local conditions, and the path to a sustainable future requires some respect for the results of that process. In the ensuing chapters he surveys the results of studies in nine regions--Ethiopia, Zimbabwe, Uganda, India, several parts of China, Chile, Brazil, Mexico and Peru--on unfamiliar but traditional crops like sorghum, tef, milpa, sweet potatoes, and the like, which suggest that these foodstuffs are uniquely suited to these areas and are more appropriate than Western grains. The work being done by scientists in these countries therefore focusses on how to maximize the yields of these native plants, but their work tends to be understaffed, underfunded and unappreciated. The nations after all tend to be poor, their best minds tend to emigrate to the industrialized West and there's not much interest on the part of powerful multinational corporations in these marginal crops. This is where McKnight and other non-governmental organizations (NGOs) come in, providing seed money (quite literally) to keep local scientists working to improve local crops. The best section of the book is Manning's rational and dispassionate discussion of bioengineering. Though he maintains a healthy respect for the dangers that genetic manipulation of crops could co
