Bright spots in US corn production

We adopt an approach known as bright spots analysis to identify U.S. regions with surprisingly high corn yields given regional expectations, seasonal weather, and soil characteristics. These counties are regional "surprises" that, by definition, …

Past and current dynamics of US agricultural land use and policy

How has agricultural land use and land cover changed? What are the major policy shifts associated with these changes? We show that U.S. agriculture has gradually trended toward an intensely regulated and specialized system. Crop production is …

Changing yields in the central US under climate and technological change

This paper projects the race between technologically driven increases in crop yields and changing climatic conditions in the central USA, one of the world's most productive agricultural regions. Using the highest, average, and lowest decadal rates of …

The impact of agricultural landscape diversification on US crop production

This research uses hierarchical Bayesian models to estimate the relationship between landscape-scale agricultural diversity and the yields of corn, soy, and winter wheat in the coterminous United States. We find that the yields of corn and winter …
