Design of government policies that seek greater adoption of anaerobic digesters can benefit from a greater understanding of the motivations for adoption. Using a nationwide survey of U.S. dairy and swine producers, this study seeks to determine how policies, peer group influences, environmental beliefs, and farm characteristics affect the decision to adopt a digester. Results suggest that neighborhood effects, farm type and size, and nonmarket benefits of anaerobic digestion are important for predicting whether or not a producer will consider this technology for manure management. However, the decision to actually adopt is more dependent on government policies and economic considerations.

This paper discusses the three invited papers presented in the session titled “New Regulations Require New Solutions: Federal Provisions Governing Concentrated Animal Feeding Operations” (i.e., CAFOs). These papers provide an excellent review of current state and federal laws and an excellent summary of what has been and is currently being done with respect to CAFO regulation. The papers present three different policy approaches: i) alternative performance standards, ii) location-specific regulation, and iii) insurance-based underwriting of CAFO discharges. Each approach has its drawbacks; however, blending these suggested policies into current regulation would result in efficiency gains.
