Partnerships between private sector ecotourism operators and local communities in the Okavango Delta, Botswana: A case study of the Okavango Community Trust and Wilderness Safaris partnership

Botswana is, however, different in having the highest gross domestic product per capita in Africa, relatively low population densities and high levels of socio-economic development. Inequality, however, remains high.

Second, a lack of comparative empirical methods in many studies has limited the identification of causal factors affecting sustainability.
