Botswana is semi-arid, due to the short rain season. However, the relatively high altitude of the country and its continental situation gives it a subtropical climate.
Politics of Botswana takes place in a framework of a parliamentary representative democratic republic, whereby the President of Botswana is both head of state and head of government, and of a multi-party system. Executive power is exercised by the government. Legislative power is vested in both the government and the Parliament of Botswana. Since independence the party system has been dominated by the Botswana Democratic Party (BDP), which has never lost power since independence. The Judiciary is independent of the executive and the legislature.
There are various traditionally produced alcoholic drinks. Bojalwa ja Setswana (the beer of Batswana) is brewed from fermented sorghum seeds. Other tribes, like Bakalanga, use lebelebele (millet). A commercially produced and packaged beer, Chibuku, brewed from either maize or sorghum, is a favourite drink particularly in the villages, towns, and in some parts of the city.
