Agroecology theory is not endless. A point is reached where the central elements become visible, equations distill, and a conceptual apex is reached. This is agroecology condensed into core concepts and theorems describing how crops relate to each other, the land, and their surroundings. This book covers advanced agroecology, including agroecological theory as well as applications of biodiversity that underwrite agroecology. Since much of agroecology theory is new, the resulting algorithms are equally novel, though presented so as to be useful and appreciated by less mathematically inclined professionals.
