Economy The area where Cochabamba is situated is commonly referred to as the granary of Bolivia. Its climate is milder than that of the Altiplano region to the west and thus permits extensive agriculture, including grains, potatoes, and coffee in the highlands and sugar cane, cocoa beans, tobacco, and fruit in the Chapare tropical lowlands of the South American Amazon region, an area that had been one of the country's main coca-leaf-producing regions. Cochabamba is also the industrial hub of Bolivia, producing cars, cleaning products, cosmetics, chemicals, and other items like cement. The economy of Cochabamba is characterized by producing goods and services. Recently, the software industry is becoming increasingly important. International companies like GOJA and Assuresoft also have subsidiaries in Cochabamba. Due to this industry growth, Cochabamba is called the "Silicon Valley of Bolivia", with a high demand for professionals immersed in technological careers such as Systems Engineering, Telecommunications and Information Technology. The airline Boliviana de Aviación has its headquarters in Cochabamba. The defunct airline Lloyd Aéreo Boliviano (LAB Airlines) had its management offices on the grounds of Jorge Wilstermann Airport in Cochabamba. In Cochabamba construction has been rapidly increasing in the last couple of years with more than 750 construction sites per year.
