The shape persistence of a crop yield probability density function (PDF) was studied by using two variants of the Visual Impact Method (VIM) to elicit subjective estimations by farmers. In one variant ten weights were used to describe the PDF and in the other variant the farmer chose the number...

Decision Support Systems under Multiple Objectives (MODSS) has been classified as a specific type of system within the broad family of DSS and has been one of the most active areas of research. However, despite its theoretical development large scale real-world applications of multi-objective...

Smoke from fire is a local, regional and often international issue that is growing in complexity as competition for airshed resources increases. BlueSky is a smoke modeling framework designed to help address this problem by enabling simulations of the cumulative smoke impacts from fires...

We describe a two-stage model of global log and chip markets that evaluates the spatial and temporal economic effects of government-subsidized fire-related mechanical fuel treatment programs in the U.S. West and South. The first stage is a goal program that allocates subsidies according to fire...

An international wheat trade model incorporating climate variability is used to simulate different scenarios when wheat producers in the USA, Canada, and Australia adopt El Niño/Southern Oscillation (ENSO)-based climate forecasts for use in production decisions. Adoption timing and rates are...

The impact of livestock grazing on water quality, especially erosion and sedimentation, is an important concern in the southwestern United States. In response to Federal and State regulations, Best Management Practices (BMPs) for rangeland management are being developed and implemented in many...

The economics of information is a broad field covering all aspects of information including decision making. We briefly describe 4 methods used to model the decision-making process. This is not an exhaustive list of the methods used to value information, nor are differences between the methods...

To be immediately useful in practical applications that employ daily weather generators, seasonal climate forecasts issued for overlapping 3-month periods need to be disaggregated into a sequence of 1-month forecasts. Direct linear algebraic approaches to disaggregation produce physically...

This investigation addresses a practical question from an agricultural planning and management perspective: are the NOAA/CPC seasonal climate forecasts skillful enough to retain utility after they have been downscaled to field and daily scales for use in crop models to predict impacts on crop...

Rangelands and pastures are found in every state and cover 55% of the land surface of the United States. Taken as a whole, from Western deserts and grasslands to meadows and woodlands, rangelands comprise some 364 million ha or 80% of the land in the 17 Western states. The vast expanses and...
