Economics of downscaled climate-induced changes in cropland, with projections to 2050: evidence from Yolo County California
Hyunok Lee, Daniel A. Sumner 2015. This article establishes quantitative relationships between the evolution of climate and cropland using daily climate data for a century and data on allocation of land across crops for six decades in a specific agro-climatic region of California. These relationships are applied to project how climate scenarios reported by the Intergovernmental Panel on Climate Change would drive cropland patterns into 2050. Projections of warmer winters, particularly from 2035 to 2050, cause lower wheat area and more alfalfa and tomato area. Only marginal changes in area were projected for tree and vine crops, in part because although lower, chill hours remain above critical values.

Port Slowdown Impacts California Agriculture.
Georgi T. Gabrielyan and Daniel A. Sumner. ARE Update, Vol. 18, No. 4, 2015.
The West Coast port delays that began in the summer of 2014 and lasted until near the end of February 2015 cost California agriculture dearly. As the delays extended into the winter, citrus exports were hit while exports of storable crops to Asia also slowed. The story for wine is more complex, because California both imports and exports wine through West Coast ports.

Dairy Policy in Canada and the United States
Daniel A. Sumner, Joseph Balagtas and Martha Hall Findlay, July 2014.
An integrated North American dairy market will benefit consumers and producers alike, but it requires policy changes on both sides of an open border. To avoid disruptive trade disputes, the United States needs to remove its remaining dairy subsidies in tandem with Canadian reforms to deal with supply management.
