Sun glint causes the White Nile River to appear truly white as it flows past the fields of the Gezira Scheme in Sudan. The Blue Nile borders this agricultural area to the east. The two rivers converge at Khartoum, near the top of the image.

The Gezira Scheme is one of the largest irrigation projects in the world, now covering about now covers 3,400 miles² (8,800 km²) in the Sudanese state of Al Jazirah. It is composed of thousands of kilometers of canals that distribute water from the Blue Nile to farms between the two rivers.

The Gezira (which means “island”) is particularly suited to irrigation because the soil slopes away from the Blue Nile and water therefore naturally runs through the irrigation canals by gravity . The soil has a high clay content which keeps down losses from seepage. The main crop grown in this region is still cotton.

The Nile River, generally regarded as the longest river in the world, can be seen making its way through Egypt (above) and Sudan (below) in this image of northern Africa. Here, the stretch of the river from Lake Nasser (above) to the confluence of its two major tributaries, the White Nile and Blue Nile, near Khartoum (below).

Upon opening the full image, two other segments of the great river can be observed. The first is a part of the river north of Lake Nasser, surrounded by fertile green land. The second is south of Khartoum, and includes the agricultural land of the Gezira Scheme.

The Nile River makes its way northeast through Sudan, towards Egypt. In the upper part of the image, it curves around and southwards before resuming its northward trajectory.

This curve separates two regions of desert: the Nubian Desert and the Bayuda Desert. Thee area above is part of the former, while the terrain below belongs to the latter.

The Nubian Desert is in the eastern region of the Sahara Desert, spanning 50,000 km² of northeastern Sudan between the Nile and the Red Sea. The arid region, a largely sandstone plateau, has lots of wadis flowing towards the Nile. There is virtually no rainfall in the Nubian, and there are no oases.

The Bayuda Desert, on the other hand, is located north of modern Khartoum, west of Kadabas, and south of the Nubian Desert, together making up part of the Sahara’s eastern flank.

Sudan and Ethiopia - June 21st, 2009

The golden yellow terrain of Sudan darkens to brown before crossing the border into Ethiopia, where it takens on a green tint in some areas.

Lake Tana, in Ethiopia’s highlands, appearing greenish in color here, provides the source of the Blue Nile River. The river flows northwest, joining with the White Nile at the city of Khartoum, in Sudan.

Just below the rivers’ confluence is the Gezira Scheme, a huge irrigation project that distributes water from the Blue Nile via a series of canals and ditches to farms lying between the banks of the two rivers. This agricultural area appears slightly greenish here.

Dust Storm over Central and Northern Sudan

Dust storm in Sudan - May 7th, 2009

Dust storm in Sudan - May 7th, 2009

A large dust storm covers northern to central Sudan, from the bare deserts of the North to where the land merges into dry grasslands and savanna.

The sand almost reaches the border with Egypt, although as can be seen in the full image, the skies over Egypt were clear at the time the image was captured.

Near Khartoum, the capital, air currents give the dust a spiral shape. Khartoum is prone to dust storms, particularly in the summer, called haboobs.

A haboob is a type of intense sandstorm commonly observed in the Sahara desert (typically Sudan), as well as across the Arabian Peninsula, throughout Kuwait, and in the most arid regions of Iraq.

African haboobs result from the northward summer shift of the intertropical front into North Africa, bringing moisture from the Gulf of Guinea.
