Reductions in the future agricultural workday due to climate change

Description

This repository contains workflows, scripts, and datasets that estimate the heat stress exposure of the global agricultural workforce at high spatial and temporal resolution for Ormaza-Zulueta et al. (2025). The data integrates downscaled CMIP6 climate projections from Williams et al. (2024) with global agricultural workforce estimates from Ormaza-Zulueta et al. (2024) to quantify the impact of climate change on unsafe working conditions for 2000, 2030 and 2050, under different Shared Socioeconomic Pathways (SSP2-4.5 and SSP5-8.5).
