Invest in Africa's youth before migration to Europe doubles, says UN official

With continent's population set to soar, agriculture chief Gilbert Houngbo stresses need to make rural life profitable

Economic migration from Africa to Europe driven by poverty could double in the next decade unless urgent investment is made in job creation for young people in rural areas, the head of a UN financial body has warned.

The global population is forecast to reach 9.9 billion by 2050 - a 29% increase - with most of that growth in Africa, where the population is expected to double to 2.6 billion.
