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...

In this research, we examine if and how altering the scale at which access is defined changes the estimated impact of access on diet quality and health outcomes. We also examine the extent to which there is a gradient between distance to the nearest supermarket and diet-related outcomes and...

Conversion of native sod (grassland) to cropland in the Prairie Pothole Region (PPR) is threatening important breeding habitats for migratory birds. About 50 percent of North American ducks are produced in the grasslands of the PPR, even though this habitat accounts for only ten percent of duck...

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...
