- Africa (Wikipedia)
Africa is the world’s second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth’s land area and 6% of its total surface area. With 1.4 billion people as of 2021, it accounts for about 18% of the world’s human population. Africa’s population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, ahead of Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Africa an important economic market in the broader global context.
- Botswana, officially the Republic of Botswana, is a landlocked country in Southern Africa. Botswana is topographically flat, with approximately 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, Zambia to the north and Zimbabwe to the northeast. Being a country of slightly over 2.4 million people, and roughly the size of France, Botswana is one of the most sparsely populated countries in the world. It is essentially the nation state of the Tswana people, who make up 79% of the population.
