Ajdir oasis, some 100 km NW of Timimoun, north of Charouine. The gardens are surrounded by barriers of palm fronds to stop sand blowing in from the NE, and the water comes from hand dug wells that reach water some 15 meters below ground. Traditionally the water was raised by hand and beast, but now it is done with electric pumps. The local farmers told me that the water level is dropping by about one meter/year, and that the village was about 500 years old.
