General circulation models predict significant and accelerating changes in local patterns of precipitation and temperature over the next century. The vulnerability of agriculture to climate change will depend on both the biophysical impacts of climate change on crop yields and on the...

We conduct an econometric analysis of the factors influencing U.S. crop yields and acres using U.S. county level data from 1977 to 2007 and evaluate the likely effects of future climate change on U.S. crop yields based on the projected climate changes by IPCC (2001) and our estimated parameters.

The inclusion of cover crops in cropping systems brings both direct and indirect costs and benefits. The literature has shown that cover crops can improve soil conservation and productivity, potentially improving cash crop yields and decreasing cash crop production costs. Farmers will adopt...

The paper estimates an irrigation water demand function using disaggregate climate and well data over a 32 year time period. Aggregating climate information over long periods, like a year, loses important details on temporal climatic variation, while aggregating climate information over space...

We employ state panel data for the period 1961-2004 to identify the role of climate change on U.S. agricultural productivity growth using a stochastic production frontier method. We examine the patterns of productivity changes and weather variations across regions and over time. Climate...

Climate change could affect the costs and returns of livestock production by altering the thermal environment of animals thereby affecting animal health, reproduction, and the efficiency by which livestock convert feed into retained products (especially meat and milk). In the United States,...

We construct a stochastic dual model to investigate the structural adjustment of three aggregate input and two aggregate output categories in U.S. agriculture under climatic change uncertainty. A century of national annual data (1910-2011) is used in the empirical analysis. Independent and...
