Assessing the effects of alternative policies that regulate nonpoint pollution from concentrated animal feeding operations (CAFOs) requires insight into the interactions of livestock production practices, waste management technologies, and their impacts on the environment. CAFOs have been...

Informed debate on agricultural nonpoint pollution requires evaluation of regional water quality in relation to management practices. It is prohibitive, in terms of cost and time, to run the site-specific process models for regional policy analysis. Therefore, a simplified and robust...

Production data on more than 11,000 state and collective farms in Ukraine were obtained through the VASKhNIL Research Agreement between the Center for Agricultural and Rural Development (CARD) at Iowa State University and the Ukrainian Institute of Agrarian Economics. Of particular interest to...

Economic impacts are evaluated for four agricultural policies intended to increase organic carbon stored in agricultural soils. Two policies are directed at changing agricultural practices on tillage and cover crops. The other two involve alternative land use scenarios under the Conservation...

The livestock and dairy industries are consolidating and concentrating within confined geographical areas. Accompanying these structural adjustments that are under way in the dairy and livestock industries is the potential for increased point and nonpoint source pollution problems from animal...

While one of the main agricultural policy objectives of formerly planned economies is the maximization of agricultural output under a variety of domestic and international constraints, the current changes in incentive structures may be having a mitigating impact on environmental degradation....

Described in this report is the application of an integrated agro-ecological modeling system that has been constructed around Agriculture Canada's Canadian Regional Agriculture Model (CRAM) to analyze the economic and environmental impacts of proposed agricultural policies for Alberta,...

Three alternative Conservation Reserve Program (CRP) scenarios and a targeted Wetlands Reserve Program (WRP) scenario were analyzed using the Basic Linked System (BLS) of applied general equilibrium models to project their likely economic impacts on the agriculture sector of the United States....

Researchers evaluate the profitability of planting flood-tolerant crops in flood plains relative to traditional row crops under different assumptions concerning flood frequency and the level of government crop subsidy. Short rotation woody crops and herbaceous energy crops are evaluated for two...

Analysis of alternative environmental policies often requires execution of computer simulation models of the ecological or economic phenomena involved. This paper explores efficiencies to be gained by using these simulation models in a program of constructing metamodels. Constructing a metamodel...
