The study, published in the journal PLOS ONE, analyzed data on crop prices, climate variables, and planted acreage for corn, soybeans, and wheat in the United States from 1990 to 2018. The researchers found that crop prices and climate variables both play a significant role in determining how much acreage farmers allocate to each crop.
Specifically, the researchers found that:
* Higher crop prices are associated with increased acreage for that crop.
* Wetter and warmer conditions are associated with increased acreage for corn and soybeans, but decreased acreage for wheat.
* Droughts are associated with decreased acreage for all three crops.
The researchers also found that the relationship between crop prices and acreage is strongest in regions where farmers have more flexibility in what they plant. In regions where farmers are more constrained by factors such as soil type and climate, the relationship between crop prices and acreage is weaker.
The findings of this study could have important implications for farmers and policymakers. Farmers can use the information to make more informed decisions about what crops to plant and when, based on current market conditions and climate forecasts. Policymakers can use the information to develop policies that support sustainable agricultural production and mitigate the impacts of climate change.
"Our study provides new insights into how crop prices and climate variables affect the acreage farmers allocate to different crops," said study lead author Dr. Emily Chen, a research associate in the Department of Agricultural and Consumer Economics at the University of Illinois. "This information could help farmers make more informed decisions about what to plant and when, and could also inform policy decisions related to agricultural production and climate change."
The study is co-authored by Dr. Scott Irwin, a professor in the Department of Agricultural and Consumer Economics at the University of Illinois, and Dr. Lihong Zhao, a research associate in the Department of Agricultural and Consumer Economics at the University of Illinois.
