This title presents an overview of the uses and developments of the African Waterfowl Census, illustrates the usefulness of biological data to the implementation of international conventions and agreements, summarises other international waterbird conservation initiatives, and overviews each national effort within Africa. From this, a preliminary strategy for applied programmes for waterbird monitoring in Africa is proposed.
