OSU's Derrell Peel Explores Drought Impacts in 2021, 2022 and Beyond

Weekly, Oklahoma State University Extension Livestock Marketing Specialist Derrell Peel offers his expertise in the cattle industry. This is a part of the weekly series known as the "Cow-Calf Corner" published electronically by Paul Beck. Today, Peel talks about current and future drought conditions in the U.S.
At the end of November, 69% of the U.S. was abnormally dry or worse with over 53% in some degree of drought (D1-D4) according to the Drought Monitor. The Drought Severity and Coverage Index (DSCI) is calculated from the D0-D4 categories and was 181 for the U.S. in the latest week. The weekly DSCI for the U.S. has averaged 171 for the year to date. The DSCI can take on values from 0 (no abnormally dry conditions) to 500 (100% of the region in D4 or exceptional drought).
In the Drought Monitor, the West region includes nine states (AZ, CA, ID, MT, NV, NM, OR, UT and WA). The West region has had an average DSCI of 213 for the year to date and is at 212 currently. The year-to-date average DSCI is highest for Utah in this region at 436, followed by NV (398), CA (373), AZ (365) and NM (347). However, the current DSCI is highest for CA (401), followed by MT (393), UT (388), OR (380), and NV (371). The High Plains region of the Drought Monitor includes CO, KS, NE ND, SD and WY. This region has had an average DSCI of 208 for the year so far and has a current value of 188. So far this year the highest average DSCI was in ND (318), followed by WY (258), CO (242) and SD (226). At the current time in the High Plains region, WY has the highest DSCI (278), followed by CO (262) and ND (213).
The drought values above indicate how beef cattle operations are affected in various locations. However, broader cattle market impacts may occur depending on the severity of drought and the size of the cow herd in various regions. Beef cow slaughter is up 8.6% for the year to date and includes some drought liquidation but from exactly where is unclear. I created an ad-hoc index that incorporates drought conditions as measured by the DSCI and the number of beef cows in the states that make up the West and High Plains regions. With drought impacts heavily weighted, the four states of ND, MT, CA and SD show the greatest likely impacts on the U.S. beef cow herd in 2021, with lesser national impacts in UT, NM, OR, WY, NV and CO. The annual Cattle report, due out January 31, 2022, will reveal exactly where and how much beef cow inventories changed along with other cattle inventory data.
Drought in the wintertime is generally not a major cattle market issue with limited exceptions, such as the winter wheat crop (winter wheat grazing). However, the extent and level of drought in the U.S. at this time is troubling because of the potential for drought to extend into the next growing season, at least in some regions. With dry conditions persisting since 2020 in some regions, many beef cattle operations have already made significant adjustments and will have very little flexibility if the current drought extends into 2022. This could result in another severe round of cow liquidation in the first half of next year. A decade ago, severe drought caused the unplanned liquidation of some two million beef cows and affected cattle markets for several years, arguably up to the current time. It is possible it could happen again.
