Increasing concern as to how human activities impact Africa's lakes has led to
documentation and quantification of the lakes and the environmental changes taking place.
Through a combination of ground photographs, current and historical satellite images, and
narrative based on extensive scientific evidence, this publication illustrates how humans
have altered their surroundings and continue to make observable and measurable changes to
Africa's lakes and their environment.

Chapter 3 - Lake Djoudj
Lake Djoudj, Senegal
Situated in the Senegal river delta, the Djoudj
Sanctuary is a wetland of 16 000 ha, comprising a large lake, referred to as Lake Djoudj in this publication,
surrounded by streams, ponds and backwaters. These two images show the Djoudj Sanctuary before and after
the construction of the Diama Dam. The image from September 1979 shows the impact of drought on the Djoudj
Sanctuary, while the image from November 1999 shows rejuvenation of the sanctuary wetlands due to the
significant floods of that year. The two images vividly depict the impact of climate variability on the
Djoudj Sanctuary‹and demonstrate the broader need for close monitoring of the impacts of climate
variability and climate change on lake environments.
