The Copernicus Sentinel-2 captured this image of Tunisia's capital Tunis, in North Africa on 15 December 2017. This image higlights some of the country's important wetlands.
The image shows part of the Mediterranean's Gulf of Tunis, which provides natural protection for this ancient city and busy port. The area has seen a series of settlements over the last 3000 years, but arguably the most famous is Carthage, which now forms a suburb to the northeast of the centre of Tunis.
While the image offers sharp contrast between the city's urban environment and surrounding hills and agricultural fields, it also depicts several bodies of water, which are protected under the Ramsar Convention on Wetlands.
There are seven Ramsar sites around Tunis, five of which are visible in the image. Lake Tunis can be seen close to the coast and features a causeway. It is a brackish lagoon surrounded by intertidal marshes. It offers good nesting grounds for several species of bird and wintering grounds for species such as the Greater Flamingo. Mammals include rodents and bats, and it is an important source of food, a spawning ground and a nursery for several fish species. The main human activity carried out is fishing, regulated according to its protected status.
