Middle East – June 9th, 2013

A plume of dust blows in a diagonal line across northern Saudi Arabia and Jordan in the upper half of this image. Visible southeast of the plume is an area of circular, irrigated fields near the town of Tabarjal, in northern Saudi Arabia. In the full image, dust can be seen spreading over the southern part of the Red Sea as well.

Desert Agriculture in Saudi Arabia

Saudi Arabia - June 1st, 2012

A great number of circular green and brown fields contrast with the surrounding orange and tan desert sands of arid Saudi Arabia. This agricultural technique is known as Center Pivot Irrigation – water from deep underground is pumped to the surface and distributed via large center pivot irrigation feeds.

These circular fields range from a few hundred meters in diameter to as much as 3 km (2 miles) across. Although the fields may appear to be dotted randomly across the landscape, they actually are planned by engineers who follow ancient river channels now buried by the desert sand.

Libya - December 30th, 2011

Close-up of agriculture

The large, dark brown area in the Libyan Desert on the left side of the main image is the Haruj, a large volcanic field. It spreads across 45,000 km2 (17,000 sq mi) in central Libya, and contains about 150 volcanoes, including numerous basaltic scoria cones and about 30 small shield volcanoes, along with craters and lava flows.

Near the right edge of the main image, and visible at a greater magnification in the close-up, is desert agriculture. These fields appear circular due to center-pivot irrigation (sometimes called central pivot irrigation or circle irrigation), a method of crop irrigation in which equipment rotates around a pivot, creating a circular pattern in crops when viewed from above.

Al Jabel Al Akhdar and Irrigated Fields East of the Haruj, Libya

Libya - August 18th, 2011

The brown area along the coastline of Libya is location of the Al Jabel Al Akhdar, meaning the Green Mountain. The range runs parallel to the Mediterranean Sea, east of the Gulf of Sidra. Visible to the north, near the top edge, is the island of Crete.

Moving south, the Haruj volcanic field appears as a large, brown expanse near the bottom edge. In the full image, between two sand dune seas east of the Haruj, some areas of circular, irrigated fields can be seen, arranged in rows.

Irrigated Fields of New Valley Project, Egypt – May 30th, 2011

Egypt - May 18th, 2011

The New Valley Project (Toshka Project) consists of building a system of canals to carry water from Lake Nasser to irrigate the sandy wastes of the Western Desert of Egypt, which is part of the Sahara Desert.

The canal inlet starts from a site lying 8 km to the north of Toshka Bay (Khor) on Lake Nasser. The canal continues westward until it reaches Darb el-Arbe’ien route, then moves northward along Darb el- Arbe’ien to the Baris Oasis, covering a distance of 310 km.

The number of circular, irrigated fields in the area has increased over the years (click here for previous images).
