The welfare benefits from potential rice yield-enhancing and water-saving research programs and their distributional implications under alternative farm program provisions are compared. This is done in an ex ante surplus maximization framework by using a multiregional, price endogenous...

An analysis is done on the potential effects of several improved cropping practices in a subsistence agricultural farming system along with analyses of other development options. The farming system is modeled as a linear programming model. The problem involves mixture of perennials and annuals,...

Global climate change from increases in atmospheric carbon dioxide and other trace gases is an issue of international concern. Adverse climate conditions are expected to reduce crop yields and alter the demand for and supply of water. These potential adjustments imply economic costs to...

An analysis is conducted on the port component of the United States grain export system. A transshipment model is utilized which covers both United States internal and foreign shipments of corn, soybeans, and wheat during the four quarters of a year. The model suggests that there will be quarter...

Irrigation, under conditions where water has a high opportunity cost, could be interruptible with water use, only occurring when water is plentiful. Pacific Northwest case studies indicate interruption can substantially lessen the opportunity cost of new irrigation developments, although not...

This study attempts to provide relative magnitudes of average and marginal costs of off-site sediment-related costs in OregonÂ’s Willamette Valley. Water treatment; road, river channel, and dam maintenance; and hydroelectric generation are examined. Road maintenance and water treatment are...
