The report identifies the Caatinga biome in Northeast Brazil as highly vulnerable to climate change, with family farmers facing the greatest risks. Using an aridity index, the study demonstrates that increased drought leads to significant relative productivity losses in beans, corn, and cattle compared to other Brazilian biomes. These climate shocks are correlated with severe socioeconomic declines, including increased poverty, child mortality, school delay, and unemployment. The authors argue that a 'rural just transition' in the region must integrate social development policies with the adoption of low-carbon agricultural technologies to increase the resilience of the most exposed producers.
