Least cost solutions for a three million gallon a day land application of municipal wastewater system are estimated for three levels of capital cost subsidy: no subsidy, 7 5 percent, and 85 percent. Irrigation of reed canarygrass is superior of alfalfa, corn, forests, and natural vegetation...

One of the most important groundwater problems in Oregon, Washington and Idaho is the long-term decline of the groundwater surface level, which has been intensified by wells through discharging water from aquifers. Groundwater contamination from agriculture aggravates the depletion problem in...

Research and observations indicate climate change has and will have an impact on On- tario eld crop production. Little research has done to forecast how climate change might in uence the Canadian Federal-Provincial Crop Insurance program, including its premium rates and reserve fund balances, in...

Mounting evidence indicates climate change will adversely influence agricultural crop yields and cause greater year-to-year variability. This paper considers how a rational, forward-looking and competitive commodity market would account for these anticipated changes and thereby influence time...

Perennial crop production is inherently dynamic due to several salient physical characteristics including an establishment period of several years with low or no yields, long lives in commercial production (40 years or more), and path-dependence of yields on input use and other exogenous...

This study seeks to provide a rigorous theoretical and empirical understanding of the effects of exogenous geographic and climate-related factors on the first three moments of crop yields. We hypothesize that exogenous geographic and climate factors that have beneficial effects on crop...
