A remote oasis in Tunisia's desert was exhausted by decades of wasteful water use for agriculture -- but now pioneers around an eco-lodge are reviving the spot with innovative projects.
They hope their back-to-basics approach can keep alive the ancient Saharan caravan stop and its traditions as a sustainable alternative to the region's high-irrigation date plantations.
"Among the palm trees, everything can grow," said Mohamed Bougaa, 63, a farmer in the remote Nefta oasis, a seven-hour drive from the coastal capital Tunis.
"There's everything you need here: vegetables, fruit. We can plant peppers, tomatoes, carrots -- everything grows when there's sun and water."
The problem has been that the Nefta spring -- which once delivered some 700 litres (185 gallons) of water per second -- has been exhausted to irrigate the region's famous dates, called "deglet nour".
"The Nefta springs dried up 20 years ago," said Bougaa.
As underground water sources have failed and summer temperatures peaked at a scorching 55 degrees Celsius (131 degrees Fahrenheit) last August, the season's crop has been disappointing.
- Mimicking nature -
Patrick Ali El Ouarghi, who runs an eco-tourism lodge in the oasis, said date palm plantations, at the right scale, can be run sustainably.
He called them an ideal demonstration of permaculture, a system for producing food organically by mimicking natural ecosystems.
"The palm trees protect the fruit trees, and the fruit trees protect the vegetable patches, it's natural in an oasis," El Ouarghi said.
The French-Tunisian set up his Dar Hi lodge 11 years ago -- including the so-called "Palm Lab" where engineers, architects and artists discuss how to conserve the oasis.
The ecology project aims "to make investors and farmers want to reinvest in the oasis, because it's decaying a bit", he said.
A key theme is tackling the severe water shortages by experimenting with technology such as drip irrigation.
The current system of flooding orchards with water, pumped from 100 metres (300 feet) below ground, is wasteful, he said. Read More…
