Between 9000 and 4000 BC the arid Sahara was actually covered with savannas and forests, and was perfect grazing land with regular rainfall but due to climate change and possibly overgrazing, it became the world’s largest desert.
As the pressure increases to Feed 9 Billion, and we see our own climate changing, we need to utilise as much land as possible for crop production. Previously considered impossible, but, due to recent research undertaken by Cornell University, agriculturalists are now beginning to plant Super Vegetable Gardens or allotments in the Sahara. This is largely due to unlocking the secret of the ancient Amazonian farmers, Terra Preta or carbon-sink biochar.
These New Oasis projects have been spearheaded by Pro-Natura International with the use of local people, the nutrient rich black earth which actually replenishes itself is worked into plots along with animal dung and compost, which then yield vegetable crops of 100 tonnes per hectare per year. This is more than enough to feed the local population and provides a surplus to sell.
This has already been successfully initiated with the help of JTS Concept in Algeria, Mauritania, Chad, Burkina Fasso and Senegal.
