Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Because of the ideological differences between industrial or mechanized agriculture and agroecology, its application has thus far been relatively limited in the U.S. (the country where industrial agriculture has been advanced the furthest).

Some countries where agroecological research and practice have flourished include Costa Rica, Cuba and Brazil.
