Ribeirão Prêto's air quality reflects its position as one of São Paulo state's major agribusiness capitals in the interior Canaã plateau, with vehicle emissions from the growing metropolitan area combining with seasonal sugarcane burning from the surrounding sugarcane belt that historically generated some of Brazil's most severe agricultural burning episodes. Mechanised harvesting has reduced but not eliminated the seasonal burning contribution.
