My doctoral dissertation was a study of how the natural resource base of agriculture affects technological change--and how technological change, in turn, can affect the natural resource base of agriculture.  My subsequent work in this area pursues similar themes.

Some research highlights in this area are:

Maryland farmers' adoption of some best management practices is highly responsive to adoption costs, suggesting that cost sharing can induce substantial increases in adoption.  Several practices appear to be complements.

Subsidies for conservation on working farmland can worsen environmental problems by inducing farmers to expand the amount of land cultivated and by increasing cultivation intensity.

Farmers in the Northern High Plains tend to use center-pivot irrigation systems on low-quality land (sandy soils) that is more vulnerable to groundwater contamination.  Commodity price supports may exacerbate problems of groundwater quality and excessive depletion of groundwater stocks in fossil aquifers.
