Buba is the largest city in southern Guinea-Bissau, lying on the Rio Grande de Buba, near the Contanhez National Park. It has a population 6,815 (2008 est).[1] It is also a seaport and is the capital of the Quinara Region.[citation needed] Former President of Guinea-Bissau Kumba Yala planned to move the capital city to Buba.[citation needed] Construction is under way for a deepwater port that could host three 70-tonne vessels at any given time. It is being built by Angola Bauxite in order to export bauxite.[2] The Portuguese constructed an army camp in Buba, which, shortly after independence, was used as the headquarters for a Dutch Foreign Aid Project aimed at providing the villages of Quinara and Tombali with safe drinking water. The construction of a plywood factory through Swedish Foreign Aid in 1982 boosted the economy and growth of Buba, as it installed a steam engine which produced enough electricity to supply the whole town.
