Pwani Region
TL;DR
Coastal doughnut around Dar with Bagamoyo heritage and Mafia Island marine park
Pwani (Coast) Region surrounds Dar es Salaam without containing it—a doughnut economy dependent on the commercial capital's overflow. Beach tourism at Bagamoyo (UNESCO World Heritage site and former slave trade port) and Mafia Island Marine Park attract visitors. Salt production and fishing supplement coastal agriculture. The Bagamoyo port expansion was planned as Dar es Salaam alternative. The region's colonial history as slave trade terminus and German East Africa capital created infrastructure that modern tourism repurposes. Mangrove ecosystems provide coastal protection and nursery habitat for fisheries.
