CropSyst is a multi-year, multi-crop, daily time step cropping systems simulation model developed to serve as an analytical tool to study the effect of climate, soils, and management on cropping systems productivity and the environment. CropSyst simulates the soil water and nitrogen budgets, crop growth and development, crop yield, residue production and(More)
A n assessment of the potential impact of climate change and the concurrent increase of atmospheric carbon dioxide (CO 2) concentration on eastern Washington State agriculture was conducted. Climate projections from four selected general circulation models (GCM) were All climate projections reflect a warming future climate, but the individual GCMs vary with(More)
This paper argues that an integrated assessment (IA) approach, combining simulation modelling with deliberative processes involving decision makers and other stakeholders, has the potential to generate credible and relevant assessments of climate change impacts on farming systems. The justification for the approach proposed is that while simulation(More)
T he Yakima River Reservoir system supplies irrigation water to over 180,000 irrigated hectares (450,000 acres). Runoff is derived mostly from winter precipitation in the Cascade Mountains, much of which is stored as snowpack and runs off in the spring and early summer. Five reservoirs within the basin have cumulative reservoir storage of approximately 30%(More)

C limate change is expected to bring potentially significant changes to Washington State's natural, institutional, cultural, and economic landscape. Addressing climate change impacts will require a sustained commitment to integrating climate information into the day-today governance and management of infrastructure, programs, and services that may be(More)
Crop models of crop growth are increasingly used to quantify the impact of global changes due to climate or crop management. Therefore, accuracy of simulation results is a major concern. Studies with ensembles of crop models can give valuable information about model accuracy and uncertainty, but such studies are difficult to organize and have only recently(More)
An integrated systems approach under development for watershed restoration in the Northwest Wheat and Range Region in the Pacific Northwest was described and applied to an example watershed in northern Idaho. Two constraints placed on model development are that input data is based on publicly available data sources, and that the models do not require(More)
Prediction of plant water status is necessary for the judicious application of regulated deficit irrigation. CropSyst, a generic crop growth model that is applicable to fruit trees, was used to forecast plant water potential for irrigation management recommendations in a pear orchard. Plant water potential is predicted along with tree transpiration using(More)
