Lake Kivu in western Rwanda marks the border with the neighbouring DRC. The four ports will be built with the help of the Netherlands, and spread out from the north to the south of the lake. They will promote improved mobility for passengers and goods between the various districts along the bank. Within twenty years, they should handle the majority of commercial cross-border trade and some 3 million passengers. The Government is also keen to use the ports as a platform for more ambitious plans to kick-start water-based transport on other lakes and rivers in Rwanda. The aim is to reduce the use of onshore transport infrastructures, maintenance of which represents a significant portion of the national budget. Finally, the project will help to boost competitiveness for both the food industry (beer, tea, coffee) and the cement industry, while also giving a lift to the tourist sector.
