Namibia, officially the Republic of Namibia, is a country in southern Africa whose western border is the Atlantic Ocean. It shares land borders with Zambia and Angola to the north, Botswana to the east and South Africa to the south and east. Although it does not border Zimbabwe, less than 200 metres of the Zambezi River (essentially a small bulge in Botswana to achieve a Botswana/Zambia micro-border) separates them at their closest points. Namibia has a population of 2.1 million people and a stable multi-party parliamentary democracy. Agriculture, herding, tourism and the mining industry – including mining for gem diamonds, uranium, gold, silver, and base metals – form the basis of Namibia’s economy. Given the presence of the arid Namib Desert, it is one of the least densely populated countries in the world. Namibia enjoys high political, economic and social stability.
