Namibia faces a number of challenges providing health care to its citizens. The country has a dual system of public (serving 85% of the population) and private (15%) health care providers. In the financial year 2006/07, Government and private health expenditure combined accounted for 8.3% of the country's Gross Domestic Product.
A river is a large body of water that flows over land in a long channel. Most rivers begin high in the mountains or hills. A river's source may be a melting snowfield or glacier (although in Namibia we generally rule these 2 options out!), a spring, or an overflowing lake. As a river flows in its channel, it receives more water from streams and other rivers, and from rainfall. At the end of a river is its mouth, where the water empties into a larger river, a lake, or an ocean.
Windhoek is the capital and largest city of the Republic of Namibia. It is located in central Namibia in the Khomas Highland plateau area, at around 1,700 metres (5,600 ft) above sea level. The population of Windhoek in 2012 was 322,500 and grows continually due to an influx from all over Namibia.
