| | | | | The fertile green territory of Egypt's Nile Delta provides a notable contrast to the bare desert of the Sinai Peninsula in this Envisat view.
Only 2.5% of Egypt's land area is suitable for agriculture, corresponding to the Nile Valley and Delta. These low-lying floodplains are some of the oldest intensively cultivated areas on Earth, supporting up to 1600 inhabitants per square kilometre.
This 14 February 2005 image was acquired by Envisat's Medium Resolution Imaging Spectrometer (MERIS), working in Full Resolution Mode with a spatial resolution of 300 metres and width of 670 km.

| | | | | This Envisat ASAR Wide-Swath radar artificially coloured image shows Lake Tumba (Ntomba), and next to it the longest river in Central Africa, the Congo River, which flows 4,374 kilometres (2,718 miles) from Zambia to the Atlantic Ocean. The Congo also gives its name to the Democratic Republic of the Congo and Republic of the Congo, both countries lying along its banks. The river is also called the Zaire and is noted for its enormous basin, which includes all of Democratic Republic of the Congo (formerly Zaire) and portions of Angola, Zambia, Burundi, Rwanda, Central African Republic, the Republic of the Congo and Cameroon, making it the largest drainage basin in Africa. The cities of Kinshasa and Brazzaville are on opposite sides of the river at the Pool (bottom image), then the river narrows and falls through a number of cataracts in deep canyons and onward to the sea.

| | | | | The narrow, man-made Lake Kariba, located along the border of Zambia and Zimbabwe, as seen by Envisat. Lake Kariba was created in the late 1950s by the construction of a largest dam wall across the Zambezi River running through the Kariba Gorge.
Today Lake Kariba is one of the largest dams in the world, with a surface area of 5580 square kilometres and an average depth of 29 metres, increasing to a maximum of 97 metres. It is 220 km long and in places up to 40 kilometres wide.
The Medium Resolution Imaging Spectrometer (MERIS) acquired this image on 6 June 2005, operating in Full Resolution mode with a spatial resolution of 300 metres. It covers an area of 672 by 672 kilometres.
