Zanzibar, a Tanzanian archipelago, is experiencing a severe alcohol shortage due to supply chain disruptions, leading to a near 100% increase in beer prices. The shortage began when the Zanzibar Liquor Control Board delayed licensing permits for its three main importers, and the issue persists as new firms undergo a lengthy vetting process. This situation could significantly impact the tourism industry, which accounts for approximately 90% of the archipelago's foreign revenue.
