Infiltration of water and its effects on soil erosion : a computational analysis pertaining to central Tunisia

Creator:: Tobbi, Belgacem
Abstract:: The purpose of this study was to use computer analysis of soil and rainfall data to predict the possible occurrence of soil erosion in Central Tunisia. Analysis was done with the program OR-NATURE (M.Ungs et al, 1985) . Central Tunisia was subdivided into northern, central, and southern subzones. Data about...

Simulation of cattle cycle demography: cohort analysis of recruitment and culling decisions in the national beef cow herd

Creator:: Nordblom, Thomas L.
Abstract:: This study expresses the hypothesis that historical patterns of national beef cow herd accumulation and liquidations (the cattle cycle) have been related to investment incentive differences across cow ages through time, resulting each year in changes in herd age structure, performance and potentials for adjustment in subsequent years. A review...

Separability tests on wheat production functions in Oregon

Creator:: Bhadra, Binayak Prasad
Abstract:: Many natural resources such as water and forests have become more intensively used in recent years. Often, this has made it necessary to reallocate these resources from less to more efficient productive usage. The knowledge of the existing tradeoffs between alternative uses are necessary to make reallocative decisions. However, these...

Risk modeling using direct solution of expected utility maximization problems

Creator:: Lambert, David K.
Abstract:: A model of agricultural decision making is developed and tested in this thesis. The expected value of utility evaluated under alternative outcomes is directly maximized in a nonlinear programming model. Two features of the model distinguished it from traditional risk programming models. First, alternative attitudes towards the assumption of risk...

Strategy selection in the Oregon trawl fisheries

Creator:: Harman, Ellen Jean
Abstract:: The ocean fishery is an example of a common property resource industry. Behavior of commercial fishermen is determined by a complex set of economic, environmental and social factors. All of these factors contribute to the individual fisherman's success. Fishermen learn to cope with the variability inherent to their occupation. Two...

An economic evaluation of on-farm strategies for reduction of nitrate groundwater pollution : the case of irrigated production in the Columbia basin

Creator:: Johnson, Scott Lee
Abstract:: Technological advances in agricultural production over the past 40 years have contributed to the high standard of living enjoyed by many in the United States. Extensive use of chemicals to enhance yield and improve crop quality has played a major role in creating this highly productive U.S. agricultural system. Increased...

The economic effects of ozone on U.S. agriculture : a sector modeling approach

Creator:: Hamilton, Scott A.
Abstract:: Tropospheric ozone is a pollutant which has detrimental effects on crop yields. The level of ambient ozone can be reduced by environmental policy changes and enforcement. The purpose of this study was to estimate the welfare effects of such changes in ambient ozone using recently available plant response data and...
