Why did Colombia begin producing more goods domestically during the Great Depression?

Colombia began producing more goods domestically during the Great Depression primarily as a response to the collapse of its export-led economy.12

In the late 1920s, the nation relied heavily on the export of coffee, petroleum, and bananas. When the value of these commodities dropped precipitously during the global economic crisis of the 1930s, the country faced a severe decline in its ability to import foreign goods. To address this, Colombia adopted a policy of import substitution, which involved replacing imported products with those manufactured domestically. This shift marked the beginning of a transition toward self-sufficiency in the production of nondurable consumer goods, a trend that continued through the mid-20th century.123
