Botswana

Botswana ( (listen), also UK: ), officially the Republic of Botswana (Setswana: Lefatshe la Botswana; Kalanga: Hango yeBotswana), is a landlocked country in Southern Africa. Botswana is topographically flat, with up to 70 percent of its territory being the Kalahari Desert. It is bordered by South Africa to the south and southeast, Namibia to the west and north, and Zimbabwe to the northeast. Its border with Zambia to the north near Kazungula is poorly defined due to being in the midst of the Zambezi River. This border with Zambia is, at most, a few hundred metres long.A mid-sized country of just over 2.3 million people, it is one of the most sparsely populated countries in the world. About 10 percent of the population lives in the capital and largest city, Gaborone. Formerly one of the world's poorest countries—with a GDP per capita of about US$70 per year in the late 1960s—Botswana has since transformed itself into an upper middle income country, with one of the world's fastest-growing economies.Homo sapiens had first inhabited the country over 200,000 years ago. The Tswana ethnic group were descended mainly from Bantu-speaking tribes who migrated southward of Africa to modern Botswana around 600 AD, living in tribal enclaves as farmers and herders. In 1885, the British colonized the area and declared a protectorate under the name of Bechuanaland. As decolonization occurred, Bechuanaland became an independent Commonwealth republic under its current name on 30 September 1966. Since then, it has been a representative republic, with a consistent record of uninterrupted democratic elections and the lowest perceived corruption ranking in Africa since at least 1998.The economy is dominated by mining, cattle, and tourism. Botswana has a GDP (purchasing power parity) per capita of about $18,825 per year as of 2015, one of the highest in Africa. Its high gross national income (by some estimates the fourth-largest in Africa) gives the country a relatively high standard of living and the highest Human Development Index of continental Sub-Saharan Africa.Botswana is a member of the African Union, the Southern African Development Community, the Commonwealth of Nations, and the United Nations. The country has been adversely affected by the HIV/AIDS epidemic. Despite the success in programmes to make treatments available, and to educate the populace about how to stop the spread of HIV/AIDS, the number of people with AIDS rose from 290,000 in 2005 to 320,000 in 2013. As of 2014, Botswana has the third-highest prevalence rate for HIV/AIDS, with roughly 20% of the population infected.
