Fields of the Gezira Scheme in Al Jazirah, Sudan

15.5N 32.5E

March 10th, 2011 Category: Rivers

Sudan - February 10th, 2011

The thumbnail image focuses on the Gezira Scheme, an irrigated agricultural project between the Blue and While Nile Rivers. In the full image, a larger section of the rivers’ courses can be observed as well.

The Gezira Scheme is one of the largest irrigation projects in the world. It is centered on the Sudanese state of Al Jazirah, just southeast of the confluence of the Blue and White Nile. 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.

Dahlak Archipelago, Lake Tana and Gezira Scheme, Eastern Africa

Sudan, Ethiopia and Eritrea - November 9th, 2010

The blue waters of the Red Sea occupy the upper right corner of this image of eastern Africa. In the sea, just off the coast of Eritrea, are the islands of the Dahlak Archipelago.

Moving further inland, Lake Tana can be seen in the Ethiopian highlands. It appears tan in color from sediments. Upon opening the full image, the large Dek Island can be seen in the lake.

While much of the land west and immediately north of the lake appears green and brown in color, it becomes significantly more arid as one moves towards the upper left quadrant, west of the Nile River in Sudan.

The convergence of the Blue Nile (right) and the White Nile (left) Rivers to make the Nile River itself can be observed in the upper left quadrant as well. The irrigated fields between the two rivers up to their point of confluence are part of the agricultural project known as the Gezira Scheme.

Geographical Features in Countries Around the Red Sea

Countries by Red Sea - October 21st, 2010

This image shows various countries around the Red Sea, in Africa and the Middle East. As one moves southward, the terrain changes from arid desert to more fertile, vegetated green land.

Visible to the north of the Red Sea is part of Saudi Arabia, mountainous near the coast. Moving south and crossing over the sea, one comes to Eritrea, along the coast, and then to Ethiopia, further inland. The tan, sediment-filled lake near the bottom edge is Lake Tana, in the Ethiopian highlands.

In the upper left corner, part of Egypt is visible by Lake Nasser, on the Egypt-Sudan border. The left side of the image belongs mostly to Sudan. The Nile River can be seen on this side of the image. In the lower left quadrant, the convergence of the Blue Nile (right) and the White Nile (left) can be observed, with the irrigated agricultural project of the Gezira Scheme situated between the two rivers.

Nile River Passing by Gezira Scheme in Sudan

Sudan - October 13th, 2010

The curved greenish line that crosses this image is a portion of the Nile River in Sudan. While much of the thumbnail image is tan and arid, upon opening the full image, much greener and more fertile lands can be observed to the south.

Much of this green terrain is part of the Gezira Scheme, a large agricultural zone that uses the waters of the Nile for irrigation. The scheme, in the bottom half of the thumbnail, is located below the confluence of the Blue Nile (right) and White Nile (left) Rivers. One of the largest irrigation projects in the world, it provides water to an agricultural area of around 8,800 km².

Lake Nasser and Nile River, Egypt and Sudan

Egypt - June 2nd, 2010

Lake Nasser, on the border of Egypt (above) and Sudan (below) in the upper right corner, appears dark silver in color due to sun glint. Several smaller lakes are visible to the west; these are the Toshka Lakes, created by excess waters from Lake Nasser.

While the left side of the image is mostly sandy desert, the Nile River makes its way across the right side of the image in large curves. The river’s waters are used for irrigation in areas such as the Gezira Scheme, a large agricultural zone partially visible in the lower right corner.
