CROP YIELDS RANDOM IN RECENT YEARS? Kuang-hsing
After three to four decades of substantial inlittle evidence of a trend, it is considered to crease, yields per acre of major U.S. crops aphave plateaued. The second objective is to pear to have tapered off. The average annual investigate whether a crop yield series, if rate of growth in crop yields' decreased trendless, is random or oscillatory and, if nonmarkedly from 2.7 percent for the 1950...
متن کاملWeather Anomalies, Crop Yields, and Migration in the US Corn Belt
We investigate the influence of weather anomalies on net migration in the Eastern United States using a county-level panel for the period from 1970 to 2009. There is a significant weather-migration relationship in the Corn Belt, but not outside of it. We present evidence that weather affects migration through its influence on agricultural productivity using an instrumental variables approach. O...
متن کاملOn Technological Change in Crop Yields
Technological changes in agriculture tend to alter the mass associated with a segment or subpopulation of the yield distribution as opposed to shifting the entire distribution upwards. We propose modeling crop yields using mixtures with embedded trend functions to account for potentially different rates of technological change in different subpopulations of the yield distribution. By doing so w...
متن کاملCan improvement in photosynthesis increase crop yields?
The yield potential (Yp) of a grain crop is the seed mass per unit ground area obtained under optimum growing conditions without weeds, pests and diseases. It is determined by the product of the available light energy and by the genetically determined properties: efficiency of light capture (epsilon i), the efficiency of conversion of the intercepted light into biomass (epsilon c) and the propo...
متن کاملConditions Current Crop Yields Climatic Change Scenario I Altered Biophysical Conditions Altered Crop Yields Step
Increasing concentrations of atmospheric C O 2 and other greenhouse gases are expected to contribute to a global warming. This paper examines the potential implications of a climatic change corresponding to a doubling of atmospheric concentrations of CO2 on crop production opportunities throughout Ontario, a major food producing region in Canada. The climate is projected to become warmer and dr...
