The Lake Malawi/Nyasa/Niassa Catchment (LMNNC) supports exceptionally high diversity and endemism of freshwater species. This globally recognised centre of freshwater biodiversity is of extreme importance, not only for its biodiversity value but also for our understanding of evolutionary processes and species sorting.

The Lake Victoria Basin is internationally recognised for its high freshwater species diversity and endemism, which are of critical importance to local livelihoods and national economies within the basin. However, freshwater ecosystems within the region are highly threatened, with current safeguards proving inadequate and the focus of much past and ongoing conservation work in the region focussing on terrestrial ecosystems.

The inland waters of Madagascar and the Indian Ocean islands hotspot support a high diversity of aquatic species with high levels of endemism. The information presented in this report will help support implementation of multilateral Environmental Agreements in Madagascar, such as the Ramsar Convention and the Convention on Biological Diversity, guiding conservation planning and priority setting at national level.

This volume gives the most up-to-date information on the distributions and conservation status of species in all inland water ecosystems across mainland continental Africa and the reasons behind their declining status. This represents the most comprehensive assessment yet of freshwater biodiversity at the species level for an entire continent. For managers, this information will assist in designing and delivering targeted action to mitigate and minimise these threats.

For billions of people throughout the world – especially the poorest – wetlands are critical for livelihoods. Wetlands are also home to an enormous diversity of wildlife, much of it unique to freshwater habitats. Traditional separate biodiversity and livelihood assessment and economic valuation fails to present the full value of a wetland in the face of alternative wetland uses, and as a result wetlands are lost through development activities.
