Excerpts: Historically, grain exports from Brazil have relied heavily on road transportation to bridge long distances between major production regions and Brazilian ports. However, the expansion and consolidation of new transport corridors, as well as the addition of new railways and waterways, have made exporting corn and soybeans much more efficient. Over the past decade, Brazil has continuously increased grain production through rising productivity, an expansion of cultivated areas, and an increased number of harvests, particularly corn harvests. As a result, combined corn and soybean production more than doubled between 2010 and 2023, from 124 million tons to 287 million tons. This study analyzes the most recent modal share changes for Brazil’s corn and soybean exports and chronicles improvements in transportation infrastructure, from 2010 to 2023.
