The Landscape of Farming: An Exploration of Spatial Bio-Economic Characterization Approaches

Publication Date: November, 2015

This dissertation consists of three inter-related but standalone papers focused on the theme of measuring the spatial, bio-economic attributes of production agriculture.

Global High-Resolution Soil Profile Database for Crop Modeling Applications

Publication Date: October, 2015

One of the obstacles in applying advanced crop simulation models such as DSSAT at a grid-based platform is the lack of gridded soil input data at various resolutions.

Long-run and Global R&D Funding Trajectories: The U.S. Farm Bill in a Changing Context

Publication Date: October, 2015

We present new evidence that today's middle-income countries—notably China, Brazil, and India— are not only growing in relative importance as producers of agricultural innovations through investments in public R&D, they are also gaining considerable ground in terms of their share of privately performed research of relevance for agriculture.

Research Investment Implications of Shifts in the Global Geography of Wheat Stripe Rust

Publication Date: October, 2015

Comparing the cost of developing stripe-rust-resistant varieties of wheat with the cost of stripe-rust-induced yield losses, we estimate that a sustained annual research investment of at least US$32 million into stripe rust resistance is economically justified.

Rethinking Yield Gaps

Publication Date: April, 2015

We clarify the terminology surrounding yield gaps, show that closing yield gaps is not necessarily economic, and conclude that food security will be better served by policies that directly enhance the productive capacity of agriculture to supply affordable food efficiently and sustainably.

The Potential Distribution of Invading Helicoverpa Armigera in North America: Is It Just a Matter of Time?

Publication Date: March, 2015

Helicoverpa armigera has recently invaded South and Central America, and appears to be spreading rapidly. We update a previously developed potential distribution model to highlight the global invasion threat, with emphasis on the risks to the United States.

Moving Matters: The Effect of Location on Crop Production

Publication Date: March, 2015

Our new spatial output indexes show that 16 to 21 percent of the increase in U.S. corn output over the 128 years beginning in 1879 was attributable to spatial movement in production.

Essays on Agricultural Production, Risk, and Productivity

Publication Date: February, 2015

This dissertation takes two different research perspectives to address the central theme of agricultural production and productivity.

Long-run and Global R&D Funding Trajectories: The U.S. Farm Bill in a Changing Context

Publication Date: January, 2015

We present new evidence that today’s middle-income countries—notably China, Brazil and India— are not only growing in relative importance as producers of agricultural innovations through investments in public R&D, they are also gaining considerable ground in terms of their share of privately performed research of relevance for agriculture.
