This paper models control of invasive buffelgrass (Pennisetum ciliare), a fire-prone African bunchgrass spreading rapidly across the southern Arizona desert as a spatial dynamic process. Buffelgrass spreads over a gridded landscape. Weed carrying capacity, treatment costs, and damages vary over...

This study examines the spatial nature of optimal bioinvasion control. We develop and parameterize a spatially explicit two-dimensional model of species spread that allows for differential control across space and time, and we solve for optimal control strategies. We find that the qualitative...

Although there have been numerous studies on the economics of weed control, relatively few of these studies have focused on natural ecosystems. The aims of this papers are: A) to identify the combination of control options that is optimal for blackberry (Rubus anglocandicans) in Australian...

As environmental deterioration and global warming arouses more and more attention, identifying cleaner and more environmentally friendly energy sources is of interest to society. In addition to environmental concerns, both the high price of gasoline and the fact that the United States has heavy...

The nitrogen cascade concept indicates that agriculture serves as a significant link between emissions of the potent greenhouse gas (GHG) nitrous oxide and losses of nitrate-N to surface waters. Conservation practices have the potential to exploit this link, as their implementation is found to...

Landowner characteristics influence his/her willingness to change landuse practices to provide more or less environmental benefits. However, most studies of agricultural/environmental polices identify landowners as homogenous. And, the primary cause of failure of many environmental and other...

In this paper, we simulate the Brazilian agriculture and transportation fuel sectors using a price endogenous mathematical programming model to analyze the impacts of recent changes in fuel policies and strong demand in world sugar markets on producers’ supply responses, consumers’ driving...

There is a need for cost-effective methods to reduce nitrogen pollution from agriculture. Marginal abatement cost (MAC) curves for nitrate-nitrogen pollution in an agricultural watershed are evaluated using estimated crop yield and nitrate pollution production functions for alternative cropping...
