The purpose of the present study was to determine willingness to pay for improved water quality and sanitation in four rural communities of El Salvador using the Contingent Valuation Method. The research was conducted between November 1998 and January 1999. Different regression estimates reveal...

Agriculture is one of the major sources of water quality impairment, and chemical fertilizer causes most of the surface water contamination. The purpose of this thesis is to design two fertilizer tax systems (Uniform Tax vs Differentiated Tax) embodied in a Computable General Equilibrium model,...

A multiyear regional risk programming model was used in evaluating the impacts of different environmental policies on cropping systems, input use, nonpoint source pollution, farm income and risk. A direct expected utility maximizing problem (DEMP) objective with a Von Neuman Morgenstern utility...

In Afghanistan, where 80% of the population is rural, irrigated agriculture is important for satisfying subsistence needs. While most of the irrigated agriculture is fed by diversion canal systems which tap surface flows, legal and physical water infrastructure in the region is generally poor. A...

Predicted crop yields and wind erosion rates from a multi-year/multi-crop growth simulation model provided input into a multi-period recursive QP model to evaluate erosion implications during the transition to dryland crop production on the Texas Southern High Plains. Three farm-program...

Vegetable production can offer a high-valued cash crop alternative. While returns may be high, vegetables are perceived to have more risk than conventional row crops. This study used stochastic dominance analysis to evaluate terminal market price risk for four vegetable crops across five market...

Linear programming and regional input-output models were applied to estimate the impacts of increased pumping costs for irrigated agriculture due to groundwater depletion principally caused by the expanding urban area of San Antonio, Texas. A biophysical simulator was use to estimate linear...

A multiyear regional risk programming model was used in evaluating the impacts of different environmental policies on cropping systems, input use, nonpoint source pollution, farm income and risk. A direct expected utility maximizing problem (DEMP) objective with a Von Neuman Morgenstern utility...
