Effects of Nutrient Restrictions on Confined Animal Facilities: Insights from a Structural-Dynamic Model

摘要: Nutrient emissions from animal feeding operations continue to degrade water and air quality. New regulations will limit the amounts of nutrients that can be locally applied land. In this paper, a structural-dynamic model livestock-crop operation is calibrated with data representative farm used predict effects nitrogen regulations. Policy simulations clarify importance dynamic elements demonstrate three main results: (1) cost estimates for large producers are higher than suggested by previous studies; (2) cross-media pollution potentially significant; (3) improved input management appears most promising reducing both waste costs.
