Dr. Robin Naidoo, Senior Conservation Scientist, WWF-US, discusses ecological and socioeconomic aspects of community-based conservation in Namibia. The benefits of biodiversity conservation to the provision of ecosystem services have been inferred from many studies of systems in controlled laboratory conditions.  Research on how varying degrees of biodiversity affect tangible economic benefits in real-world socioeconomic systems is much more scarce.  In this Gund Tea Robin shows how biodiversity impacts income generation on communal conservancies in Namibia, both in terms of aggregate gains and efficiencies in production.
