Today is Africa Day. And here is a fact most Africans have never been taught.
Between 500 BCE and 700 CE, a civilization called the Garamantes built 750 kilometers of underground irrigation tunnels beneath the Sahara Desert in what is now Libya. They had no river. They built gravity-fed channels that pulled water from deep aquifers and turned desert into farmland that fed a population of 50,000.
They grew grapes, figs, wheat, olives and dates in the middle of the Sahara.
Modern engineers still study these tunnels today for sustainable irrigation solutions. But this is not taught in most African schools. Just like the building techniques, the craftsmanship, and the engineering knowledge before it, we are losing it without ever knowing we had it.
