Optimal Regional Policies to Control Manure Nutrients to Surface and Ground Waters

摘要: Current day large animal facilities generate more manure than they need on their own feed production areas. Excessive nutrient applications deteriorate groundwater (nitrogen) and surface water quality (nitrogen and/or phosphorus). Due to differences in environmental economic characteristics, adjacent regions may have differing objectives for nitrogen phosphorus abatement. We postulate an analytical model of upstream agricultural downstream recreational regions, analyze optimal policies that consider both regions. show depending the tightening regulation with respect loading one only might increase other. As prevailing regulatory tool livestock is Nutrient Management Plan based standard; because main source man-made loads environment, high importance. Our contributes literature by i) differentiating (the impacts of) between farm crop ii) showing how this differentiation carried over relative absolute amounts due changes application uptake; areas iii) allowing regional abatement objectives.
