Democratic Republic of the Congo - March 5th, 2010

This FAPAR image portrays the vegetation index of a wide central area of the Democratic Republic of the Congo. The country is situated at the heart of the west-central portion of sub-Saharan Africa and straddles the Equator, with one-third to the North and two-thirds to the South.

As a result of its equatorial location, the Congo experiences large amounts of precipitation and has the highest frequency of thunderstorms in the world. The annual rainfall can total upwards of 80 inches (2,032 mm) in some places.

This precipitation sustains the Congo Rainforest, the second largest rain forest in the world (after that of the Amazon). This massive expanse of lush jungle covers most of the vast, low-lying central basin of the river. Most of the land visible here shows good to high photosynthetic activity, indicated by the mostly green to red tones.

Smoke from agricultural fires in central Africa blows towards Lake Volta, near the coast in the lower half of this image. The lake is the largest reservoir by surface area in the world, and the fourth largest one by water volume. It is located completely within the country of Ghana, and it has a surface area of about 8,502 kmĀ² (3,275 square miles).

Lake Volta lies along the Greenwich Meridian, and just six degrees of latitude north of the Equator. The lake’s northmost point is close to the town of Yapei, and its southmost extreme is at the Akosombo Dam, 520 kilometers downstream from Yapei.

Akosombo Dam holds back both the White Volta River and the Black Volta River, which formerly converged, where the middle of the reservoir now lies, to form the single Volta River. The present Volta River flows from the outlets of the dam’s powerhouse and spillways to the Atlantic Ocean in southmost Ghana.

This huge reservoir was formed beginning in 1965, when the large Akosombo Dam was completed. Because of the formation of Lake Volta, about 78,000 people were relocated to new towns and villages, along with 200,000 animals belonging to them. About 120 buildings were destroyed, not including small residences.
