Demand for fertilizer in developing countries has expanded at a rapid rate over the past forty years. The relative scarcity of agricultural land has been a major underlying cause of this expansion in demand. More proximate causes include the development of complementary Green Revolution...

Public research is a major contributor to agricultural productivity growth, but if research investments are not maintained, agricultural productivity can decline over time. Maintenance research replaces deteriorated research knowledge to forestall a productivity decline. Knowledge of the...

Efforts to improve public agricultural research efficiency include calls to increase use of competitive grants. This paper empirically assesses different instruments the USDA uses to fund state-level research. Compared with other instruments, competitive grants focus more on basic research and...

Recent criticisms of the “green revolution” wheats concern the effects of their popularity on crop diversity and the consequences for productivity and conservation. We use a Just-Pope production function to test the relationship of genetic resource and diversity variables to mean and...

Following the failure of legislative proposals for a multi-sector greenhouse gas (GHG) cap-and-trade policy, the shift in focus to energy sector policies ignores the perhaps substantial potential for GHG mitigation from agriculture/forestry. We review estimates of the current U.S. agriculture...
