Juazeiro's air quality reflects its position in the São Francisco River valley on the Bahia-Pernambuco border in the semi-arid Nordeste, with vehicle emissions from the BR-407 and the surrounding fruit irrigation farming corridor and hydroelectric power operations contributing local sources. The São Francisco valley's channelling of northerly and southerly winds provides generally reasonable ventilation, while drought conditions and Caatinga burning contribute seasonal PM10 elevation across this major São Francisco valley agricultural hub.
