Brian gave us good news from Ann Arbor. Here is what economists say about land use: large, monocultural farms with no windbreaks are best suited to fight erosion. Huh???

Olin School of Business One Brookings Drive Campus Box 1133 St. Louis, MO 63130-4899 UNITED STATES ABSTRACT: We provide a new and more complete analysis of the origins of the Dust Bowl of the 1930s, one of the most severe environmental crises in North America in the 20th Century. Severe drought and wind erosion hit the Great Plains in 1930 and lasted through 1940. There were similar droughts in the 1950s and 1970s, but no comparable level of wind erosion. We explain why. The prevalence of small farms in the 1930s limited private solutions for controlling the downwind externalities associated with wind erosion. Drifting sand from unprotected fields damaged neighboring farms. Small farmers cultivated more of their land and were less likely to invest in erosion control than were larger farmers. Soil Conservation Districts, established by government after 1937, helped coordinate erosion control. This 'unitized' solution for collective action is similar to that used in other natural resource/environmental settings.
