If you think the local weather forecaster has trouble predicting if it will rain tomorrow, imagine how hard it is to forecast crop production world-wide.
If there is too little rain in Brazil in August, it could delay planting of the country’s summer maize crop and subsequently diminish that harvest. If the decrease is big enough, it could possibly have implications for international commodity prices and might even impact global food security. This in turn can translate into the need for policy makers to respond to economic and trade issues and problems in countries where food insecurity is a persistent threat.
