|dc.description.abstract||With rising demographic growth, there is increasing interest in analytical studies that
assess alternative policies to provide an optimal allocation of scarce natural resources while
ensuring environmental sustainability. This dissertation consists of three essays in applied
resource economics that are interconnected methodologically within the agricultural production
sector of Economics.
The first chapter examines the sustainability of biofuels by simulating and evaluating an
agricultural voluntary program that aims to increase the land use efficiency in the production
of biofuels of first generation in the state of Alabama. The results show that participatory
decisions may increase the net energy value of biofuels by 208% and reduce emissions by
26%; significantly contributing to the state energy goals.
The second chapter tests the hypothesis of overuse of fertilizers and pesticides in U.S.
peanut farming with respect to other inputs and address genetic research to reduce the use
of the most overused chemical input. The findings suggest that peanut producers overuse
fungicide with respect to any other input and that fungi resistant genetically engineered
peanuts may increase the producer welfare up to 36.2%.
The third chapter implements a bioeconomic model, which consists of a biophysical
model and a stochastic dynamic recursive model that is used to measure potential economic
and environmental welfare of cotton farmers derived from a rotation scheme that uses peanut
as a complementary crop. The results show that the rotation scenario would lower farming
costs by 14% due to nitrogen credits from prior peanut land use and reduce non-point source
pollution from nitrogen runoff by 6.13% compared to continuous cotton farming.||en_US
