Egypt plan to green Sahara desert

It looks like a mirage but the lush fields of cauliflower, apricot trees and melon growing among a vast stretch of sand north of Cairo's pyramids is all too real - proof of Egypt's determination to turn its deserts green.

While climate change and land over use help many deserts across the world advance, Egypt is slowly greening the sand that covers almost all of its territory as it seeks to create more space for its growing population. With only five percent of the country habitable, almost all of Egypt's 74 million people live along the Nile River and the Mediterranean Sea. Already crowded living conditions - Cairo is one of the most densely populated cities on earth - will likely get worse as Egypt's population is expected to double by 2050.

The government is keen to encourage people to move to the desert by pressing ahead with an estimated $70 billion plan to reclaim 3.4 million acres of desert over the next 10 years. Among the incentives are cheap desert land to college graduates.But to make these areas habitable and capable of cultivation, the government will need to tap into scarce water resources of the Nile River as rainfall is almost non-existent in Egypt.

The plan has raised controversy among some conservationists who say turning the desert green is neither practical nor sustainable and might ultimately backfire. The wisdom of using precious water resources to grow in desert areas unsuited to cultivation and where water will evaporate quickly under the scorching sun. Egypt may be setting the stage for a scenario that's ultimately detrimental to itself.
