Climate-Related Indices for Agricultural Production

Summary

Agricultural production faces significant challenges from climate change, particularly due to drought, altered growing seasons, and heat stress on both crops and laborers. This report compiles and explains several common climate indices—such as SPI, SPEI, GDD, and LMGP—that are utilized to characterize and quantify these climate-related impacts. The work is ongoing as these indices are applied to better understand and predict vulnerabilities in different agricultural systems.
