[SIZE=5]Fossil water[/SIZE][SIZE=5] or paleowater is an ancient body of water that has been contained in some undisturbed space, typically groundwater in an aquifer, for millennia.[/SIZE]
Huge reserves of underground water in some of the driest parts of Africa could provide a buffer against the effects of climate change for years to come, scientists said.
Researchers from the British Geological Survey and University College London have for the first time mapped the aquifers, or groundwater, across the continent and the amount they hold.
‘The largest groundwater volumes are found in the large sedimentary aquifers in the North African countries Libya, Algeria, Egypt and Sudan,’ the scientists said in their paper.

They estimate that reserves of groundwater across the continent are 100 times the amount found on its surface, or 0.66 million cubic Kilometers.
Writing in the journal Environmental Research Letters, they cautioned, though, that not all these reserves can be accessed.
Where they can, small-scale extraction using hand pumps would be better than large-scale drilling projects, which could quickly deplete the reservoirs and have other unforeseen consequences.

Groundwater is no panacea for Africa’s water shortages but it could form an important part of a strategy to cope with an expected sharp increase in demand for water as the continent’s population increases.
Villagers, majority of them elders, don’t understand the reason why Northern Rangeland Trust is accumulating millions of acres in arid areas of Kenya. 70 years from today white men will be feeding kenyans at a very high price. Our lands, our cheap labour, white masters
I believe you. Right now in Angola, the Chinese have leased 1000s of acres and are growing Rice and exporting it straight to China. The Kuando Kubango Rice Project

The project is located in Longa town, 70km away from Menongue, the capital city of Cuando Cubango Province, Angola. The farm occupies 4,500 hectares of land. The project contains construction of the followings: 1,500 hectares of rice farm alongside the bank of River Longa, irrigation facilities, grain drying, storage and processing facilities, office and dormitory buildings, and agricultural equipment.The project is designed to have 10,000 tons of annual rice production and 20,000 tons of annual rice processing capacity. http://www.camce.com.cn/en/enBA/enEC/enAP/201503/t20150310_57568.htm
Yeah! Let us destroy the Earth completely! We’ll migrate to Mars, after all, won’t we?
We ought not to have extracted oil in the first instance! They say it is about to get depleted. And it’s only a few 70 years of intensive mining, having been forming and retained there underground for hundreds of millions of years! How long will it be before we deplete those underground waters?
The us supported mobutu even when he publicly executed lumumba…after that, they have secretly been causing chaos through armed militia as they loot resources. Just as they do with the arabs… Why dont they intervene in somalia? The place is only good for growingg fruits and charcoal business
These guys have EVERYTHING that you need to live well from reliable rains, fertile soils, forests, minerals but the white terrorists made sure that they will never enjoy peace so that the foreigners can continually steal…
