Fig. 2. Analysis of interview data reveals a correspondence between three key biophysical scales and overlapping social scales (Atwell 2008). Corn Belt social-ecological systems are configured at multiple scales with a strong infrastructure to support increased row crop production while providing only a fraction of the comparable support for conservation practices. Analysis of the responses of our interview subjects shows that successful diffusion of perennial conservation practices must consider the social-ecological context surrounding practices at multiple scales including: consistent, straightforward, flexible, and carefully targeted incentives and regulations; reinforcement through social networks, norms, and support structures; and compatibility with farm priorities, profitability, practices, and technologies. These are many of the same factors that are currently arranged to support increased row crop production of corn and soybeans.
