Resumen
Descripción
As of June 2023, the U.S. National Oceanic and Atmospheric Administration (NOAA) declared that El Niño conditions were present and consensus existed among climate prediction centers that El Niño would likely persist from November 2023 to February 2024.
El Niño is typically associated with seasonal climate anomalies and extreme weather events throughout the developing world, especially across sub-Saharan Africa, but the economic impacts caused by these events are difficult to disentangle from those of other climate shocks, natural disasters, and economic cycles. Additionally, the strength and consistency of El Niño’s agroclimatic impacts vary by region.
El Niño’s unique slow onset, periodic pattern, and lead times of prediction (from a few months to a year) make it possible to design anticipatory policies and prepare emergency responses in advance.
Policymakers should closely monitor the evolution of El Niño-Southern Oscillation (ENSO) phases and the potential impacts of El Niño and be prepared to coordinate policy responses quickly as the situation unfolds.
As global warming continues and climate extremes occur more frequently, actions to foster climate-resilient agrifood systems should be broadly prioritized.
