Sure you've heard of the Nile Delta with it's life-giving, crop-growing waters. But have you ever heard of the Okavango Delta?
Located in Botswana, this delta is responsible for maintaining one of the largest swamps in the world, and is home to an incredible amount of wildlife, plants and insects - large, miniscule and everything in between. Not only is it important for the flora and fauna, but it also provides valuable resources for the people living on or near it.
The region has been compared to a living system, with pulses of water rushing through the system with rains, and nutrients building up and being exposing in regularly drying patches of land (providing valuable food for terrestrial plant life.)
But like most ecosystems in 2010, it faces threats, namely wildfires, global warming and a burgeoning elephant population.
To raise awareness and to inspire people to action, Earthprint publishers are launching a book called "Okavango Delta: Floods of Life" details the delta's complexity and wealth of life in breathtaking pictures.
