Agricultural producers in South America are contending with severe weather-related risks. In Argentina, a significant hailstorm on August 27 impacted between 30,000 and 80,000 hectares of wheat crops across regions including Bellville, Marcos Juárez, and Entre Ríos. This ~~event~~ event, caused by unexpected thermal shocks in the atmosphere, follows previous losses in corn and soy and occurs as farmers attempt to advance corn planting to mitigate the projected effects of a strong El Niño phenomenon. In Chile, the focus has shifted toward protecting fruit orchards from hail and microtornados. These weather events are identified as critical threats, particularly during the flowering stage and the period preceding harvest. Producers are utilizing various protection strategies, including anti-hail netting, rigid covers, windbreaks, and early warning monitoring systems to prevent total crop destruction. In Brazil, the intensification of El Niño is increasing the risk of extreme weather. In Paraná, farmers have already experienced the devastating impact of tornadoes, resulting in significant property and crop losses. Meteorologists from Simepar, citing NOAA data, indicate a high probability of El Niño reaching strong intensity, which is expected to cause increased instability, frequent storms, and consecutive rainy days through the first quarter of 2027. Experts emphasize the need for rural insurance and preventive agricultural policies to mitigate these growing risks.
