By 2050, a quarter of the world's people will be African - this will shape our future | Edward Paice

Africa's unprecedented population growth will impact geopolitics, global trade, migration and almost every aspect of life. It's time for a reimagining of the continentIn 2022 the world's population will pass 8 billion. It has increased by a third in just two decades. By 2050, there will be about 9.5 billion of us on the planet, according to respected demographers. This makes recent comments by Elon Musk baffling. According to him, "the low birthrate and the rapidly declining birthrate" is "one of the biggest risks to civilisation". Fertility rates in Europe, North America and east Asia are generally below 2.1 births per woman, the level at which populations remain stable at constant mortality rates. The trajectory in some countries is particularly arresting. The birthrate in Italy is the lowest it has ever been in the country's history. South Korea's fertility rate has been stuck below one birth per woman for decades despite an estimated $120bn (?90bn) being spent on initiatives aimed at raising it. Japan started the century with 128 million citizens but is on course to have only 106 million by 2050. China's population will peak at 1.45 billion in 2030, but if it proves unable to raise its fertility rate, the world's most populous country could end the century with fewer than 600 million inhabitants. This is the "big risk" alluded to by Musk. The trouble is, his statement seems to imply that "civilisation" does not include Africa. Continue reading...
