Agricultural research has fostered productivity growth, but the historical influence of anthropogenic climate change on that growth has not been quantified. We develop a robust econometric model of weather effects on global agricultural total factor productivity (TFP) and combine this model with counterfactual climate scenarios to evaluate impacts of past climate trends on TFP. Our baseline model indicates that anthropogenic climate change has reduced global agricultural TFP by about 21% since 1961, a slowdown that is equivalent to losing the last 7 years of productivity growth. The effect is substantially more severe (a reduction of ~26-34%) in warmer regions such as Africa and Latin America and the Caribbean. We also find that global agriculture has grown more vulnerable to ongoing climate change.
Ariel Ortiz-Bobea (Dyson School, Cornell University) will present in the
2021 Perspectives on the Climate Change Challenge Seminar Series:
This university-wide seminar series is open to the public, and provides important views on the critical issue of climate change, drawing from many perspectives and disciplines. Experts from Cornell University and beyond present an overview of the science of climate change and climate change models, the implications for agriculture, ecosystems, and food systems, and provide important economic, ethical, and policy insights on the issue. The seminar is being organized and sponsored by the Department of Biological and Environmental Engineering and the Cornell Atkinson Center for Sustainability.
