Computer model gives early warning of crop failure


An international team of researchers has developed a computer model to predict global crop failures several months before harvest. Since 2008, widespread drought in crop-exporting regions has resulted in large increases in food prices on global commodity markets. With climatic extremes also expected to become more common, being able to predict global crop failures could help developing nations that are reliant on food imports — making them more resilient to spikes in food prices.
