Latin American researchers used big data from 50 municipalities in Rondônia, Mato Grosso, Goiás and Tocantins to study how El Niño and La Niña affect rainfall and grain production. The team produced a revised planting calendar to reduce water-stress losses.
The work covers areas that account for 39% of Brazil's grain output.
The study is a research tool for planting-date decisions and has no immediate effect on supply or prices. Over time, better planting timing could reduce weather-related yield volatility in Brazilian grain.
