That is the Desert Lion Conservation Project in Namibia's Land Cruiser and it was sponsored by the Land Cruiser Club of South Africa. It was a standard 75 LDV converted to a DC version in South Africa.
Use this link for more images of this cruiser in action in Namibia. Whiles looking at the Cruiser images, check-out the web site and possibly see if you can contribute to the Project. Dr Stander, the research person, is a dedicated person for this job and needs all the help he can get.
Cheers
