Oeste Catarinense (West Region) is a mesoregion in the Brazilian state of Santa Catarina.
The macroregion is composed of four microregions: (1) Far west, whose main city is São Miguel do Oeste, on the border with the Argentine Republic; (2) Midwest - whose main city is Chapecó; (3) Alto Irani Region - whose main city is Xanxerê; (4) Rio do Peixe Valley Region - whose main city is Joaçaba
The region is called "granary of the State", because it has a large agroindustrial, agricultural and livestock production, slaughterhouses and food industry.[1]
In geographic terms, the region is strategically located between the two largest metropolitan areas in South America (São Paulo in Brazil and Buenos Aires, in Argentina).
