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,...

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...

This paper presents a novel approach for generating information for regulatory and policy analysis, based on farmers' adoption of weed control technology. A simulation model, WISH, is used to generate cost and risk information on 258 weed control strategies. The environmental policies simulated...

This report summarizes the major findings of a study in which an integrated agro-ecological economic modeling system was constructed around Agriculture Canada's Canadian Regional Agriculture Model (CRAM) to analyze the economic and environmental impacts of proposed agricultural policies. The...

An environmental modeling system is being constructed around the EPIC model that will be interfaced with an economic component (RS-CRAM) within an integrated modeling system to analyze agricultural policies such as GRIP for western Canada. A description of the major EPIC subcomponents is...

Atrazine is the most widely used herbicide for corn and sorghum and the most commonly encountered in surface water and groundwater. In addition to water quality problems, atrazine poses hazards through atmospheric transport, food residues, and exposure of applicators and wildlife. It atrazine...

This report describes the interface between RS-CRAM (resource sensitive Canadian Regional Agriculture Model) and the environmental components of the integrated modeling system for crops, crop sequences, and management systems representative of western Canadian agriculture. An experimentally...

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...

The trade-off between agricultural production stability and environmental sustainability is a growing concern. The two major Canadian farm income stabilization programs of 1991, GRIP (Gross Revenue Insurance Plan) and NISA (Net Income Stabilization Account), are being considered for their...

This paper presents a novel approach for generating information for regulatory and policy analysis, based on farmers' adoption of weed control technology. A systems approach and a simulation model, WISH, are used to generate cost and risk information on 221 weed control strategies. Empirical...
