Such interactions may result in a co-evolutionary arms race, consisting of repeated cycles of the emergence of new parasite offences and host countermeasures.
Therefore, provided that host resistance makeup in mixtures can be altered between cropping cycles, the risk of emergence and spread of super-races should not be a major constraint for adopting mixtures.
Thus the system continually evolves in hard-to-predict ways through a cycle of local interactions, emergence, and feedback.

The chapter also touches on theories about the role of climatic cycles on the emergence of nomadic empires and also explores the political ecology of these nomadic groups and their relationships with settled neighbours.
The complete cycle of an adverse impact, that is, the process of emergence, development, and dissipation, also is generally not modeled.
