Botswana

Botswana /bɒtˈswɑːnə/, officially the Republic of Botswana (Tswana: Lefatshe la Botswana), is a landlocked country located in Southern Africa. The citizens refer to themselves as Batswana (singular: Motswana). Formerly the British protectorate of Bechuanaland, Botswana adopted its new name after becoming independent within the Commonwealth on 30 September 1966. Since then, it has maintained a strong tradition of stable representative democracy, with a consistent record of uninterrupted democratic elections.

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 but at most is a few hundred metres long.

A mid-sized country of just over 2 million people, Botswana is one of the most sparsely populated nations in the world. Around 10 percent of the population lives in the capital and largest city, Gaborone. Formerly one of the poorest countries in the world—with a GDP per capita of about US$70 per year in the late 1960s—Botswana has since transformed itself into one of the fastest-growing economies in the world, now boasting a GDP (purchasing power parity) per capita of about $18,825 per year as of 2015, which is one of the highest in Africa. Its high gross national income (by some estimates the fourth-largest in Africa) gives the country a modest standard of living and the highest Human Development Index of continental Sub-Saharan Africa.

Okavango Delta

The Okavango Delta (or Okavango Grassland) in Botswana is a very large inland delta formed where the Okavango River reaches a tectonic trough in the central part of the endorheic basin of the Kalahari. All the water reaching the Delta is ultimately evaporated and transpired, and does not flow into any sea or ocean. Each year approximately 11 cubic kilometers of water spreads over the 6,000-15,000 km² area. Some flood-waters drain into Lake Ngami. The Moremi Game Reserve, a National Park, is on the eastern side of the Delta. The scale and magnificence of the Okavango Delta helped it secure a position as one of the Seven Natural Wonders of Africa, which were officially declared on February 11, 2013 in Arusha, Tanzania. On 22 June 2014, the Okavango Delta became the 1000th site to be officially inscribed on the UNESCO World Heritage List.

The area was once part of Lake Makgadikgadi, an ancient lake that mostly dried up by the early Holocene. Although the Okavango Delta is widely believed to be the world's largest inland delta, it is not. In Africa alone there are two larger similar geological features: the Sudd on the Nile in South Sudan, and the Inner Niger Delta in Mali.

National park

A national park is a park in use for conservation purposes. Often it is a reserve of natural, semi-natural, or developed land that a sovereign state declares or owns. Although individual nations designate their own national parks differently, there is a common idea: the conservation of 'wild nature' for posterity and as a symbol of national pride. An international organization, the International Union for Conservation of Nature (IUCN), and its World Commission on Protected Areas, has defined "National Park" as its Category II type of protected areas.

While this type of national park had been proposed previously, the United States established the first "public park or pleasuring-ground for the benefit and enjoyment of the people", Yellowstone National Park, in 1872. Although Yellowstone was not officially termed a "national park" in its establishing law, it was always termed such in practice and is widely held to be the first and oldest national park in the world. The first area to use "national park" in its creation legislation was the US's Mackinac Island, in 1875. Australia's Royal National Park, established in 1879, was the world's third official national park. In 1895 ownership of Mackinac Island was transferred to the State of Michigan as a state park and national park status was consequently lost. As a result, Australia's Royal National Park is by some considerations the second oldest national park now in existence.

Peace Corps

The Peace Corps is a volunteer program run by the United States government. The stated mission of the Peace Corps includes providing technical assistance, helping people outside the United States to understand American culture, and helping Americans to understand the cultures of other countries. The work is generally related to social and economic development. Each program participant, a Peace Corps Volunteer, is an American citizen, typically with a college degree, who works abroad for a period of two years after three months of training.

Volunteers work with governments, schools, non-profit organizations, non-government organizations, and entrepreneurs in education, business, information technology, agriculture, and the environment. After 24 months of service, volunteers can request an extension of service.

The program was established by Executive Order 10924, issued by President John F. Kennedy on March 1, 1961, announced by televised broadcast March 2, 1961, and authorized by Congress on September 21, 1961, with passage of the Peace Corps Act (Pub.L. 87–293). The act declares the program's purpose as follows:

Chobe National Park

Chobe National Park, in northern Botswana, has one of the largest concentrations of game in Africa. By size, it is the third largest park in the country, after the Central Kalahari Game Reserve and the Gemsbok National Park, and is the most biologically diverse. It is also Botswana's first national park.

Geography and ecosystems

The park can be divided up to 4 areas, each corresponding to one distinct ecosystem:
