Resumen:
This study examines the impact of climate change on aggregate food production across countries with different levels of agricultural technology. Using a dynamic panel model, we find that a 1◦C increase in global (local) temperature anomalies leads to an immediate decline in food production growth of about 3% (1%, respectively). These effects are persistent –lasting about seven years in the case of global anomalies and two years for local ones– and lead to cumulative food production losses of approximately 21.7% and 1.8%, respectively. These effects are not uniform across countries: high-tech countries appear more resilient, whereas low-tech countries experience significantly larger losses. These findings underscore the crucial role of technological adaptation in smoothing the adverse effects of rising temperatures on food production.
