Brazilian farmers are increasing productivity by cultivating more crops per year from already cleared land, reducing deforestation. The double crop system, where three quarters of Brazil's corn is produced, has been developed with short-cycle soybean and corn varieties by Brazilian scientists. Irrigation enables more crops to be grown annually in the cerrado region. However, managing such a system requires advanced skills and luck to avoid delays due to weather conditions. This approach has been environmentally beneficial, as most soybean expansion in Brazil is from degraded pastures rather than deforested areas.
