In years to come, Africa's wealthy elite will continue to dominate the territories they command now - this is what their current fortunes tell us.In many parts of Africa, personal wealth comes with great responsibility. Individuals who control a country's major industries are responsible for providing jobs for thousands of households, and generally influencing the territory's economy in a significant manner.For these elite few - the men who are consistently ranked among the world's richest people - sustaining their substantial wealth is as demanding as the effort it required to create it in the first place. In the league of Africa's rich men, there is no such thing as small money, and also, there is no such thing as 'Once rich, always rich'.We profile five of Africa's richest men and find out who is most likely to increase their fortunes over the next decade - and who will give the most back.Aliko Dangote - NigeriaDangote's wealth is currently pegged at around $10.1 billion, most of which was generated through investments in sugar, flour, and cement. The 54-year-old father of three is currently the continent's richest man, according to Forbes magazine.His claim to fame as the 'Cement King' of Africa is inspired by his dominance of the cement trade in a number of Africa countries. Dangote currently owns cement plants in Zambia, Senegal, Tanzania, and South Africa, and has also received approval to build two more plants in Cameroon and the Ivory Coast.Two years ago, Dangote Cement was listed on the Nigerian Stock Exchange, and that has since helped swell his fortunes further.So how does the Dangote story go? There are tales of how he started off with a loan from his uncle, and from there went on to spearhead the growth of the Dangote Group.Dangote is a committed philanthropist who continues to invest heavily in many social issues, including providing healthcare and access to quality education.Dangote has demonstrated beyond measure that his wealth won't fade away - at least not in the next decade.Theophilus Danjuma - NigerianDanjuma is thought to be worth about $600 million, largely derived from his holding in South Atlantic Petroleum (SAPETRO).
