to the nearest town. Therefore, travelling to town will cost a Dollar("Dala") and returning will again cost a Dollar, hence the term Daladala originated. Stone Town is the main hub for Daladalas on Zanzibar and nearly all journeys will either start or end here. There are two main Dala Dala stations in Stone Town: Darajani market and Mwanakwerekwe market. The Darajani market terminus serves the North and North East of the island and the Mwanakwerekwe market terminus serves the South and South East. As with most of East African transport, the buses do not run on set schedules – instead departing when full. As there is no fixed schedule, it is not possible to book tickets in advance (with the exception of The Zanzibus). There are plans of implementing a government-operated bus service on the island, which will bring the ground transportations more in line with the relatively developed water and air transport infrastructure, but there is currently no timeline available for this project. With Zanzibar visitor numbers set to top 1,000,000 annually, there will be increasing pressure on the current transportation network – the bus network will reduce the number of vehicles on the road and help reduce environmental impact of tourism on Zanzibar. Maritime transport Ports There are five ports in the islands of Unguja and Pemba, all operated and developed by the Zanzibar Ports Corporation. The main port at Malindi, which handles 90 percent of Zanzibar's trade, was built in 1925. The port was rehabilitated between 1989 and 1992 with financial assistance from the European Union. The Italian contractor, Salini Impregilo S.p.A., was supposed to build wharves that lasted 60 years; however, the wharves lasted only 11 years before crumbling and degenerating because the company deviated from the specifications. After a long legal battle, the company was required in 2005 by the International Court of Arbitration to pay Zanzibar US$11.6 million in damages. The port was again rehabilitated between 2004 and 2009 with a 31 million euro grant from the European Union. The contract was awarded to M/S E. Phil and Sons of Denmark. The then-director of the contractor suggested that the rehabilitation would last a minimum of 50 years. But the port is again facing problems, including sinking. Ferry accidents The MV Faith, which began its final journey at the port of Dar es Salaam, sank in May 2009 shortly before docking at the port of
