Climate-Related Indices for Agricultural Production

Gunda, Thushara; Brelsford, Christa; Goodnight, James S.

This document summarizes common indices used to characterize climate-related impacts to agricultural production. In particular, we consider indices for three phenomena: 1) drought, 2) growing period, and 3) heat stress (Table 1). It should be noted that these indices are far from exhaustive. Instead, they reflect common concerns related to production of agriculture that are emerging across multiple regions (Gunda et al., 2024). Other indices such as rate of return (Shand et al., 2024) can also be leveraged to support agriculture-related climate analyses as well.
