Application of Data Mining Techniques to Further Understand the Relationship Between Drought and Impacts in the Pacific Northwest

Project Timeline
September 2018 - August 2020

Agricultural crop insurance is an important component for mitigating farm risk, particularly given the potential for unexpected climatic events. Using a 2.8 million national insurance claim dataset from the United States Department of Agriculture (USDA), this research study examined spatiotemporal variations of agricultural insurance loss across the 24-county region of the inland Pacific Northwest (iPNW) portion of the United States, from 2001 to 2015. Applying a time-lagged algorithmic technique to find the most relevant associations between climate and insurance loss, the researchers constructed a random forest model which tracked the overall variation of insurance loss for wheat due to drought, with a modest R2 of .45. The results of this research indicate a threshold relationship between economic and climatic influences on insurance outcomes, with variations based on geography, crop regime, climate, and commodity pricing.
