It will become increasingly important, I believe, to think about how and where agrarianism--an essential for humans--is represented in the US's social, cultural, legal, and economic framework.
The focus here is on farming (and food and farmers), as one might imagine, but it's worth reading even if you are simply interested in where your food comes from. In terms of writing, the styles (and tones) vary widely, and in some cases feels somewhat uneven, though all of the writing is useful, and most (if not all) authors provide additional resources for the interested reader.
