Why did coffee production decline after Angola became independent?

Following Angola's independence in 1975, coffee production declined sharply due to a combination of political, economic, and social factors:

• Loss of Skilled Labor: The departure of a large number of skilled Portuguese workers, who had previously managed the estates and distribution systems, created a void that the local population was not prepared to fill due to inadequate colonial-era educational development.12
• Economic Disruption: The new government’s attempt to implement a state-run agricultural model, which included nationalizing foreign capital and creating state farms, proved ineffective. The collapse of manufacturing and the flight of Portuguese traders destroyed existing distribution networks.12
• Civil War: The post-independence civil war was the most significant factor. It caused widespread population displacement, destroyed physical infrastructure, and rendered the countryside insecure, effectively halting commercial production.12
• Policy Constraints: The overvaluation of the currency acted as a heavy tax on exports, removing incentives for producers to sell agricultural commodities to urban centers. Furthermore, the widespread presence of land mines buried during the conflict created a lasting impediment to agricultural activity.2
