Biodiversity in general terms deals with biological and geographical units such as genes, species, ecosystems at different levels of scale up to biogeographic regions.There are many different definitions of biodiversity among which the one used under the Convention on Biological Diversity (CBD) is one of the most frequently cited:"Biological diversity means the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems."
This definition was adopted in the formulation of Zambia's National Biodiversity Strategy and Action Plan (NBSAP). Biodiversity can therefore be considered at ecosystem, species and gene levels. Much of the work on biodiversity in Zambia is at species level and to a limited extent on ecosystems.
