Out of Africa
In Libya, say migrants, you can get beaten at any moment — or arbitrarily arrested and have the police use your cellphone to call your family in Niger and demand a ransom for your release.
.. Just as Syria’s revolution was set off in part by the worst four-year drought in the country’s modern history — plus overpopulation, climate stresses and the Internet — the same is true of this African migration wave.
.. Chaifou explains that West Africa has experienced two decades of on-again-off-again drought. The dry periods prompt desperate people to deforest hillsides for wood for cooking or to sell, but they are now followed by increasingly violent rains, which then easily wash away the topsoil barren of trees. Meanwhile, the population explodes — mothers in Niger average seven children — as parents continue to have lots of kids for social security, and each year more fertile land gets eaten by desertification. “We now lose 100,000 hectares of arable land every year to desertification,” says Chaifou. “And we lose between 60,000 and 80,000 hectares of forest every year.”
.. Says the U.N.’s Barbut, “Desertification acts as the trigger, and climate change acts as an amplifier of the political challenges we are witnessing today: economic migrants, interethnic conflicts and extremism.” She shows me three maps of Africa with an oblong outline around a bunch of dots clustered in the middle of the continent. Map No. 1: the most vulnerable regions of desertification in Africa in 2008. Map No. 2: conflicts and food riots in Africa 2007-2008. Map No. 3: terrorist attacks in Africa in 2012.
All three outlines cover the same territory.
.. “If we would invest a fraction of that amount helping African nations combat deforestation, improve health and education and sustain small-scale farming, which is the livelihood of 80 percent of the people in Africa, so people here could stay on the land,” says Barbut, “it would be so much better for them and for the planet.”
