Economic Analysis of Management Practices to Reduce Phosphorus Load to Lake Eucha and Spavinaw AgEcon
Howry, Sierra S.; Stoecker, Arthur L.; Storm, Daniel E.; White, Michael J..
Changes in management practices are often proposed to reduce phosphorus loading from a watershed due to over application of poultry litter. This study determines the choice, location, and level of each best management practice in the watershed to meet a Total Maximum Daily Load and margins of safety at least cost.
Tipo: Conference Paper or Presentation Palavras-chave: Best management practice; Phosphorus runoff; Poultry litter; Target MOTAD; Environmental Economics and Policy.

Improving Environmental Quality in South Florida through Silvopasture: An Economic Approach AgEcon
Stainback, G. Andrew; Alavalapati, Janaki R.R.; Shrestha, Ram K.; Larkin, Sherry L.; Wong, Grace.
A dynamic optimization model is used to compare the profitability of silvopasture with traditional cattle ranching in south Florida. Silvopasture can reduce phosphorus runoff from cattle ranching-a major environmental concern for Lake Okeechobee and the Everglades. Silvopasture can also sequester carbon, thereby offsetting global climate change. The effectiveness of phosphorus runoff taxes and carbon sequestration payments for inducting landowners to adopt silvopasture is investigated. We find that phosphorus taxes alone would not induce landowners to adopt silvopasture. However, payments to landowners to sequester carbon, alone or in conjunction with phosphorus runoff taxes, can make silvopasture financially competitive with traditional ranching.

Technical Efficiency, Environment Efficiency, Productivity and Beneficial Management Practices AgEcon
Lota, Tamini D.; Bruno, Larue; West, Gale E..
An input distance function (IDF) is estimated to empirically evaluate and analyze the technical and environmental efficiencies of 210 farms located in the Chaudière watershed (Quebec), where water quality problems are particularly acute because of the production of undesirable outputs that are jointly produced with agricultural products. The true IDF is approximated by a flexible translog functional form estimated using a full information maximum likelihood method. Technical and environmental efficiencies are disaggregated across farms and account for spatial variations. Our results show that there is a significant correlation between technical and environmental efficiencies. Farms that are technically efficient tend to be environmentally efficient. We...
