The first chapter began the process of defining agroecology (a) in lexicographic terms, (b) as an academic science, (c) from an economic perspective, and (d) as the basis for selecting among the many agronomically productive, land-use possibilities. Most of all, agroecology is a land-use science where at the core is a plot-demarcated agroecosystem.
This text offers a streamlined explanation as to how the many parts fit together. The goal is to arrive at a site, climate, and socioeconomically suitable agrosystems.
To achieve this, there is a central path from which all the agroecosystem designs originate. There are three steps along the agro-design path: (1) the core elements of agrosystem design, (2) the cropping threats, and their counters, arriving at (3) a recognized or novel agrotechnology. This chapter looks at the first of these steps, the core elements that form the base agroecosystem.
In agroecology, development is not complete without evaluation. This chapter also presents those economic methodologies that determine the efficacy of the core elements.
