To mark World Wetlands Day, this Copernicus Sentinel-2A image features the Okavango Delta on 2 December 2016.
A river delta usually leads to the open sea, but the delta formed by the Okavango River is different. After rising in Angola and flowing through Namibia, the river meanders into Botswana, where it branches out to create an inland delta - one of the world's most important wetlands.
Wetlands, both coastal and inland, are important for people and the environment. Their many benefits include acting as natural safeguards against disasters, protecting communities most vulnerable to the devastating effects of floods, droughts and storm surges. They also provide a habitat for a multitude of animals and plants, and filter and store water.
Every year, 2 February marks World Wetlands Day. It commemorates the Convention on Wetlands also known as the Ramsar Convention, which was signed on 2 February 1971 to provide a framework for national and international cooperation for the conservation and use of wetlands and their resources. This year's theme is 'Wetlands for Disaster Risk Reduction'.
