Structural breaks reveal accelerating climate sensitivity of global cereal production 1: European Commission, Joint Research Centre (JRC), Seville, Spain; 2: Ss. Cyril and Methodius University in Skopje, Faculty of Agricultural Sciences and Food, Skopje, North Macedonia Global cereal production is increasingly constrained by rising temperatures, yet the timing and extent of changes in crop yield sensitivity to climate remain unclear. We apply Bai–Perron structural break detection to identify candidate instability points of yield-climate data for six major crops across 156 countries (1962–2022), followed by first-difference panel regressions to quantify shifts in climate-yield relationships. Structural breaks predominantly occurred between the late 1980s and early 2000s, coinciding with agronomic and policy transitions. Post-break, yield sensitivity to temperature intensified by approximately 50–100%, while precipitation effects remained weaker and more variable. C₄ crops like maize exhibited more frequent breaks, reflecting physiological vulnerability to heat and moisture stress. These findings indicate that climate-driven yield sensitivities have accelerated historically, underscoring the need to refine yield projections and target adaptation and risk management strategies in a warming world. | |
