Context paragraphs:
Meerkat: The meerkat or suricate ("Suricata suricatta") is a small carnivoran belonging to the mongoose family (Herpestidae).  It is the only member of the genus Suricata.  Meerkats live in all parts of the Kalahari Desert in Botswana, in much of the Namib Desert in Namibia and southwestern Angola, and in South Africa.  A group of meerkats is called a "mob", "gang" or "clan".  A meerkat clan often contains about 20 meerkats, but some super-families have 50 or more members.  In captivity, meerkats have an average life span of 12–14 years, and about half this in the wild.

Watermelon seed oil: Watermelon seed oil is extracted by pressing from the seeds of the "Citrullus vulgaris" (watermelon).  It is particularly common in West Africa, where it is also called "ootanga oil" or "kalahari oil". Watermelons probably originated almost 5,000 years ago in the Kalahari Desert of Africa where botanists have found its wild ancestors still growing.  Watermelons migrated north through Egypt, and during the Roman era they were cultivated and prized.  Traditionally, the seeds are extracted from the seed casing, and dried in the sun.  Once dried, the seeds are pressed to extract the oil.

The Meerkats: The Meerkats, also known as Meerkats: The Movie, is a feature-length 2008 British wildlife fiction film which anthropomorphises the daily struggles of a clan of meerkats in the Kalahari Desert.  It was produced by BBC Films and The Weinstein Company, and filmed by the award-winning BBC Natural History Unit.  It is the debut directorial feature of James Honeyborne, previously a producer of natural history programmes for television.  The worldwide premiere was held at the Dinard Film Festival, France in October 2008, expanding to a wide release the following week.  The film was released in 2009, on 7 August in the UK.  A US date has not yet been announced.  This was dedicated to actor Paul Newman, who died in 2008, shortly before this movie was released.

Kalahari Basin: The Kalahari Basin or Kalahari Depression is a large lowland area covering over 2.5 million km covering most of Botswana and parts of Namibia, South Africa, Angola, Zambia, and Zimbabwe.  The outstanding physical feature in the basin, and occupying the centre, is the large Kalahari Desert.  The city Windhoek is situated in the Kalahari Basin.

Oxford Scientific Films: Oxford Scientific Films (OSF) is a British company that produces natural history and documentary programmes.  Founded on 8 July 1968, by noted documentary filmmaker Gerald Thompson, the independent film company broke new ground in the world of documentaries, using new filming techniques and capturing footage of never before filmed activities of its various subjects.  In 1996, Oxford Scientific Films was sold to Circle Communications, where it retained its own identity as a division within the company.  The following year, Circle Communications was taken over by Southern Star Entertainment UK.  Under the new ownership, Oxford Scientific Films continued to enhance its reputation for innovative film-making, producing multiple award-winning series and films, including the highly acclaimed Animal Planet series, "Meerkat Manor".

Meerkat Manor: Meerkat Manor is a British television programme produced by Oxford Scientific Films for Animal Planet International that premiered in September 2005 and ran for four series until its cancellation in August 2008.  Blending more traditional animal documentary style footage with dramatic narration, the series told the story of the Whiskers, one of more than a dozen families of meerkats in the Kalahari Desert being studied as part of the Kalahari Meerkat Project, a long-term field study into the ecological causes and evolutionary consequences of the cooperative nature of meerkats.  The original programme was narrated by Bill Nighy, with the narration redubbed by Mike Goldman for the Australian airings and Sean Astin for the American broadcasts.  The fourth series, subtitled "The Next Generation", saw Stockard Channing replacing Astin as the narrator in the American dubbing.

Namib: The Namib is a coastal desert in southern Africa.  The name "Namib" is of Nama origin and means "vast place".  According to the broadest definition, the Namib stretches for more than 2000 km along the Atlantic coasts of Angola, Namibia, and South Africa, extending southward from the Carunjamba River in Angola, through Namibia and to the Olifants River in Western Cape, South Africa.  The Namib's northernmost portion, which extends 450 km from the Angola-Namibia border, is known as Moçâmedes Desert, while its southern portion approaches the neighboring Kalahari Desert.  From the Atlantic coast eastward, the Namib gradually ascends in elevation, reaching up to 200 km inland to the foot of the Great Escarpment.  Annual precipitation ranges from 2 mm in the most arid regions to 200 mm at the escarpment, making the Namib the only true desert in southern Africa.  Having endured arid or semi-arid conditions for roughly 55–80 million years, the Namib may be the oldest desert in the world and contains some of the world's driest regions.

Cry of the Kalahari: Cry of the Kalahari (1984) is an autobiographical book detailing two young American zoologists, Mark and Delia Owens, and their experience studying wildlife in the Kalahari desert in Botswana in the mid-1970s.  There they lived and worked for seven years in an unexplored area named Deception Valley in the Central Kalahari Game Reserve.  With no roads and no people and the nearest civilization eight hours away they had only each other and the animals they studied as company, most of which had never seen humans before.  Their research focused mainly on lions, brown hyenas, jackals and other African carnivores.  "Cry of the Kalahari" is the personal story of the Owens' encounters with these and a myriad of other animals and depicts their own struggle to live and work in such an inhospitable and unforgiving environment.

Kalah: Kalah, also called Kalaha or Mancala, is a game in the mancala family imported in the United States by William Julius Champion, Jr. in 1940.  This game is sometimes also called "Kalahari", possibly by false etymology from the Kalahari desert in Namibia.

Kalahari Red: The Kalahari Red is a breed of goat originating from South Africa.  Their name is derived from their red coat and the Kalahari Desert.  They are generally used in meat production.
